General Description
The Pharmagard model NU‐PR797 positive pressure recirculating Compounding Aseptic Isolator (CAI) is a bench/table top model, optionally available with several base stand configurations for operation as a console model. The NU‐PR797 CAI is designed to provide a sterile positive pressure work environment for the compounding of non‐ hazardous drugs. The NU‐PR797 Isolator creates HEPA filtered unidirectional flow supply at 20 air changes per minute within both the work zone and interchange areas to assure ISO Class 5 (formerly, Federal Standard 209E, Class 100) conditions. Utilizing unidirectional flow assures a continuous stream of HEPA filtered air across the work zone and interchange areas assuring sterility and minimizing cross contamination. Once the air is through the work area, the airflow is split to front to rear. Then proceeds under the work tray, up the rear divider panel and is re‐circulated again through the supply HEPA. An additional filter assembly on top of the Isolator brings in HEPA filtered room air to assure the Isolators continuous positive pressure.

5.0 Installation Instructions 5.1 Location The location or placement of the Isolator within the pharmacy or nursing station should consider contamination risks, processes and procedures requirements for each Isolator. It is preferred, but not necessary to locate the Isolator within an ISO Class 7 buffer air quality area. At a minimum, the Isolator should be located away from personnel traffic lanes, air vents, doors, or any other source of disruptive air currents. Being an Isolator, disruptive air currents will not affect performance. However, it may affect the process of work product movement in and out of the Isolator. In addition, it may affect ergonomic user comfort. Placing the Isolator away from disruptive air currents will assure maximum CSP sterility and user comfort. Where space permits, a clear 4" (102mm) area should be permitted on all sides of the Isolator. The electrical outlet into which the Isolator is connected should be readily accessible for maintenance purposes. Do not position the cabinet to prevent access to the power cord. The power cord plug serves as the disconnect and should remain readily accessible. If the outlet is inaccessible, such as a conduit (hardwired) connection, then an appropriate warning label should be applied near the cabinets on/off switch to indicate the circuit breaker on the power distribution panel to be used. 5.2 Set‐up Instructions Remove outer shipping protection (carton or crating). The Isolator is fastened to the base skid and it is usually the best procedure to leave the skid in place until the Isolator is located in its approximate location to facilitate ease in handling. It can then be removed form the skid by removing the banding, bolts, and screws holding the Isolator to the skid. Note: There is a base filler panel on the Isolator bottom. If using forklift, the forks should avoid the filler panel area. The Isolator is attached to the skid in two methods depending upon the type of bench mount or base stand purchased. If the Isolator is directly attached to the skid, remove and place on bench mount. If the Isolator is shipped with the base stand attached, follow the instructions below for Isolator removal from skid. CAUTION, IT IS RECOMMENDED THAT NO LESS THAN TWO PEOPLE PERFORM THE SKID REMOVAL AND CASTOR/LEG LEVELER ATTACHMENT PROCESS. 5.2.1 Telescoping Base Support (BCD‐10476) The telescoping base stand is shipped installed, attached to the Isolator at its lowest height. Remove the brackets and banding holding the Isolator to the base skid. Remove the Isolator from the skid. PLEASE NOTE THE BASE FILLER PANEL IF USING A FORKLIFT. To position higher, remove 3/8” bolts (2) on each leg and rise to desired height. Re‐install 3/8” bolts (2) on each leg to lock in desired height. 5.2.2 Adjustable Base Support (BCD‐10480) The adjustable base support is shipped installed, attached to the Isolator at its lowest height. Remove the skid brackets and banding holding Isolator to the base skid. Remove Isolator from skid by pushing Isolator off the skid one corner at a time attaching either castors or leg levelers on each corner as the base plates overhang the skid. PLEASE NOTE: THE BASE FILLER PANEL IF USING FORKLIFT. IN ADDITION, IF FORKLIFT IS USED, LEAVE BASE PLATE SHIPPING BRACKET IN PLACE UNTIL ISOLATOR IS PLACED ON THE FLOOR. Once Isolator is placed on floor with either castors or leg levels, remove base plate holding bracket. Adjustable base support can now be plugged in and height adjusted with up/down switch. 5.2.3 Leveling w/Leg Levelers Using a level placed on the work tray, adjust the leg levelers first end‐to‐end, then, front to back. The NSF approved leg levelers provide a 3/4" (20mm) adjustment.

5.2.4
Bench Mount Installation (BCD‐10400) Place 2 X 2 bench mount bars on bench from front to rear the same width as the Isolator. Attach the 2 X 2 bars to the bench with the brackets provided. Note: No more than a 4‐1/2 inch (144mm) 2 x 2 bar overhang is permitted for bench top installation. Place the Isolator on the 2 X 2 bench mount bars. Attach Isolator to the bars with plate mounts. Lastly, attach plate mount covers. If desired, the joint between the bench and Isolator mounts may be sealed with silicon RTV to prevent spills from migrating under the bench mount system.
5.2.5
Gas Service NuAire does not recommend the use of natural gas within the Isolator. All NuAire Isolator’s have precautionary warning labels that say the following: Use of explosive or flammable substances in this Isolator ! should be evaluated by your appropriate safety personnel. Plumbing Services Ground key cocks with the type of service specified by the removable button on the handle, are located in the work zone. The Ground Key cocks are not recommended for pressure over 30 p.s.i. (2.0 BAR). Reducing valves should be installed external to the Isolator if necessary. Ground key cocks should never be used for flammable gasses or oxygen service. A special needle valve for oxygen service or certified valve is required and available upon request.
CAUTION
5.2.6
External connection is to 3/8 inch NPT coupling in the inner sidewalls. Connection to plant utilities should be made with proper materials for the individual service and according to national and/or local codes. Observe all labels pertaining to the type of service and operating pressure. 5.2.7
5.2.8
Drain Valve The Isolator may or may not come with the drain valve installed depending upon the basestand type purchased. If the drain valve requires installation, remove from packaging. Apply thread lock liquid provided in package and attach to threaded drain stub located on the bottom right side of the Isolator. Tighten so handle is located on the left side of valve, so the handle will be pulled forward to close the drain. Electrical Services The NU‐PR797 series Isolator is connected via an electrical power cord with hospital grade plug or optionally, “hardwired”. The unit requires 115 VAC, 60 Hz, single phase (current rating varies per CAI size, reference Electrical/Environmental Requirements). It is recommended that power to the unit be on its own branch circuit, protected with a circuit breaker or fuse at the distribution panel.
PLEASE NOTE THIS UNIT CONTAINS ELECTRONIC BALLASTS FOR THE FLUORESCENT LIGHTING. ELECTRONIC BALLASTS OPERATE WITH HIGH INRUSH CURRENT. IT IS NOT RECOMMENDED TO USE THIS PRODUCT WITH GROUND FAULT CIRCUIT INTERRUPTERS (GFCI'S) BECAUSE THE BALLASTS MAY CAUSE THE GFCI TO TRIP.

Final Assembly REMOVE THE PROTECTIVE CARDBOARD COVER OVER THE FILTERS, located on top of the Isolator. The powder coat urethane and polycarbonate glove port panel is easily cleaned with any mild household detergent. Use a soft cloth on the panels. Recommended cleaners for polycarbonate are: Formula 409 (for external surfaces only) Windex D w/Ammonia D (for external surfaces only) 70% Isopropyl Alcohol The use of polycarbonates has some important don'ts: Do Not use abrasive or high alkaline cleaners. Do Not scrape with squeegees, razor blades, or other sharp instruments. Please refer to section 12.0 for Polycarbonate material compatibility. Do not attempt to clean the HEPA filter media. Isolator interior walls or work surface are easily cleaned with any mild household detergent cleaner using a soft cloth. Page 13 of 43
5.3 Certification Testing Methods and Equipment After installation and before use, NuAire recommends that the Isolator be certified or commissioned to factory standards. At a minimum, the following tests should be performed. 1. HEPA Filter Leak test 2. Downflow Velocity (calibration) test 3. Isolator Pressure (calibration) test 4. Cleanliness Classification test 5. Enclosure Integrity test The testing methods and equipment required are specified on the factory inspection report included with this manual (see insert in back cover). IT IS RECOMMENDED THAT THESE TESTS BE PERFORMED BY A QUALIFIED TECHNICIAN WHO IS FAMILIAR WITH THE METHODS AND PROCEDURES FOR CERTIFYING ISOLATORS. PLEASE VISIT THE NUAIRE WEBSITE WWW.NUAIRE.COM UNDER TECH‐SERVICE SUPPORT AND REVIEW INDEPENDENT SERVICE TECHS FOR YOUR AREA. AFTER THE INITIAL CERTIFICATION, NUAIRE RECOMMENDS THAT THE ISOLATOR BE RECERTIFIED AT A MINIMUM ON AN ANNUAL BASIS MORE OFTEN IF REQUIRED BY REGYLATORY REQUIREMENTS AND AFTER EVERY FILTER CHANGE OR MAINTENANCE ACTION OR ANY TIME THE OPERATOR FEELS IT IS NECESSARY. Note that the Pharmagard Isolators, filters, and seals provide premium performance. Quality Control in both design and manufacturing assure superior reliability. However, protection to product and is so vital that certification to the performance requirements should be accomplished as stated by the factory standards.

6.0 Operating the NU‐PR797 6.1 Electronic Control System 6.1.1
Overview The electronic control system is designed to service the control requirements of the NU‐PR797 Isolator. The control system consists of one electronic module and several discrete components that will perform the following functions: Control blowers via solid‐state switch. Control lights via solid‐state switch. Control outlets via solid‐state switch. Disable audible alarm switch with ring back function. Control supply blower, DC ECM Motor with solid state DC Motor Controller. Monitor and display airflow system performance via minihelic gauges.
The NU‐PR797 incorporates the use of an electronic module that improves the Isolator’s performance. The main control module, through the use of the front panel, controls the on/off functions of the blowers, fluorescent lights, and outlets. All the above functions are shown in a system block diagram(see Figure 1).
OM0189 September/2014
Figure 1
Page 16 of 43
6.1.2
Front Panel The control system front panel contains the following functions described in detail (see Drawing BCD‐10313).
6.1.2.1 6.1.2.2
Blower Keys The blower keys indicate and control ON/OFF power to the blower. Light Keys The light keys indicate and control ON/OFF power to the fluorescent light.
6.1.2.3 Outlet Keys The outlet keys indicate and control ON/OFF power to the outlets. 6.1.2.4 Interchange Chamber Minihelic Gauge The Interchange chamber minihelic gauge displays positive static pressure within the interchange chamber. The gauge is calibrated in “inches of water gauge” pressure. The interchange chamber positive pressure will read greater than 0.05” w.g. during normal operation. If the external interchange door is opened, the gauge reading will drop to 0.00” w.g. Once the external interchange door is closed, again the reading will increase back to normal. If the internal interchange door is opened the gauge reading will increase and read the same as the main chamber minihelic gauge. 6.1.2.5 Main Chamber Minihelic Gauge The main chamber minihelic gauge displays the positive static pressure within the main chamber. The gauge is calibrated in “inches of water gauge” pressure. The main chamber positive pressure will read greater than 0.15” w.g. during normal operation. If the external interchange door is opened, pressure may drop, but will still read greater than 0.15” w.g. However, if the internal door is opened, the reading will decrease and read the same as the interchange chamber minihelic gauge. 6.1.2.6 Pharmagard Digital Monitor (optional) The optional Pharmagard Pressure Monitor displays the positive static pressure within the main chamber. The pressure monitor is calibrated in “inches of water gauge” pressure. The pressure monitor will read the same as the main chamber minihelic gauge and in addition, allow a low/high alarm limit point to be set. The default alarm limits is set to 0.10” w.g. low and 0.50” w.g. high. See optional equipment section for greater detail.

6.1.3
Run Mode Operation Operation of the Isolator is initiated by plugging the power cord into the appropriate power connection. In the power off condition (Isolator is unplugged) all calibration and running parameters will be stored in the microprocessor's EEPROM memory. During the power on condition (Isolator is plugged in), the Isolator blowers, lights, and outlets may be turned on. 6.1.3.1 Airflow Control The operating airflows within the Isolator as well as the inlet blower are controlled by potentiometers located in the control center on the main control board controlling the pulse width modulation (PWM) signal applied to the motor/blowers. The potentiometer is adjustable with a slotted screwdriver, which varies the PWM signal from 0 to 10 Vdc. 6.2 Operating Guidelines
!
CAUTION
DO NOT use for compounding hazardous drugs.
The intent herein is to present general operational guidelines that will aid in the use of the Isolator to provide a sterile positive pressure work environment for the compounding of non‐hazardous drugs. Regulatory and recommended guidelines, published by USP, ASHP and the state boards must be observed. In addition to regulatory and recommended guidelines, the operating guidelines are based on performance testing using the CETA CAG‐002‐2006 Compounding Isolator testing guide. The testing guide, while testing for all basic performance criteria, has two tests directly impact operating guidelines. These tests are recovery time test (2.07) and preparation ingress and egress test (2.09). The testing guide recommends that the results of these tests are noted as shown below and displayed on the CAI. The complete test results are published in the NuAire Technical Bulletin GTB0150. 2.07 Recovery time determination test results were less than 1 minute. Adding a margin of safety to this value, NuAire recommends a minimum of 5 minutes to establish the ISO Class 5 Environment within the workzone. 2.09 Preparation ingress and egress test results indicated that all particle counts were well below ISO Class 5 levels. This Isolator can be used outside an ISO Class 7 clean room with no wait or purge time required during the material transfer process. Procedure protocols defined in terms of the Isolator or control concepts unique to the Isolator must be developed in order to obtain a maximum potential for drug compounding efficiency and sterility. The pre‐planning necessary to develop these protocols is based on several fundamental considerations and each will contribute to optimum CAI use benefits. a. Know your "Safe Working Area" b. Personnel cleansing and garbing c. Product movement d. Utilize unidirectional airflow e. Employ aseptic techniques 6.2.1 Know Your "Safe Working Area" The Isolator has two distinct areas, the interchange area, and the work zone area. The interchange area has constant unidirectional airflow from the supply HEPA filter. This area remains at ISO Class 5 when the exterior access door is closed. The work zone area also has constant unidirectional airflow from the same supply HEPA filter. This area will remain at ISO Class 5 even if the exterior access door is open, however if both interior and exterior access doors are open, the possibility of contamination migrating into the work zone exists. In addition, if the front‐hinged window is opened, contamination will migrate into the workzone and require the Isolator start up operating sequence to be performed.
OM0189 September/2014
Page 19 of 43
6.2.2
6.2.3
Personnel Cleansing and Garbing Follow all personnel cleansing and garbing requirements per USP, ASHP and State Board Guidelines. Based on CETA CAG‐002‐2006 test results NuAire recommends at a minimum, all basic clothing and personal hygiene requirements should be met. No shoe, head, facial hair or face covers are required. Use standard pharmacy gown, perform hand hygiene and don sterile, powder‐free gloves. During material movement process, gloves should be sanitized with adequate frequency with an effective disinfectant. Product Movement Always plan movement in and out of the Isolator. The source of contamination is typically the room environment and the material handling process itself. Planning movement in and around the Isolator will increase efficiency and minimize the risk of contamination. In general terms, the Isolator interior door should always remain closed unless moving material from the interchange area to the workzone. This is also true for the exterior door. Typical product movement would be, to open the exterior door; move materials into the interchange area, then using the unidirectional airflow remove any final packaging and wipe down materials as they are placed on the interchange worksurface, then close the exterior door. No purge time is required for the interchange area due to the constant unidirectional airflow. Then, use the glove ports to access the interior door, open and move material into the workzone. Then close the interior door and perform aseptic compounding procedure. Then reverse the material movement procedure to remove material from the Isolator. During material removal, perform material wipe down as required to assure no hazardous material is present
6.2.4
Utilize Unidirectional Air Flow The operator must keep two important facts in mind: (1) The air, as supplied to the work area through filters from the top, is contaminant free and (2) airborne contamination generated in the work area is controlled by the unidirectional flow of parallel air streams in a top‐to‐bottom direction.
A solid object placed in a unidirectional air stream will disrupt the parallel flow and consequently, the capability of controlling lateral movement of airborne particulates. A cone of turbulence extends below the object and unidirectional air stream is not regained until a point is reached downstream, approximately equal to three to six times the diameter of the object. Within the parameters of this cone, particles may be carried laterally by multidirectional eddy currents. Transfer of viable materials and manipulations which may generate aerosols should not be performed above sterile or uninoculated materials. Items should be localized on the work surface in "clean" and "dirty" groups.
6.2.5
OM0189 September/2014
Employ Aseptic Techniques The operator must not assume an attitude of "let the Isolator do it" when performing procedures within an Isolator. Properly balanced and properly used Isolators will do an excellent job of controlling airborne contamination, but the Isolator will not eliminate contact transmission of contamination. Normal pharmacy contamination control procedures and basic aseptic techniques are necessary to obtain maximum benefits from the Isolator. Page 20 of 43
6.3 Operating Sequence 6.3.1 Start Up Turn on Isolator blowers and lights; check pressure gauges on control panel to assure positive pressure is registering. Assure the specified differential pressure between the pass‐through and main chamber. Per UPS 797, the recommended standard operating procedure states, “When LAFWs or barrier isolators are used as the ISO Class 5 air quality environment, their blowers must be operated continuously during compounding activity, including during interruptions of less that 8 hours. When the blower is turned off and before other personnel enter to perform compounding activities, only one person can enter the contiguous buffer area for the purposes of turning on the blower (for at least 30 minutes) and of sanitizing the work surface”. However, through product testing, the Pharmagard can achieve an ISO Class 5 environment in less than 1 minute. Adding a margin of safety to this value, NuAire recommends a minimum of 5 minutes to establish the ISO Class 5 environment within the workzone. 6.3.2
Wipe Down At the beginning of each compounding activity session, and after liquids are spilled, the surfaces of the direct compounding environment are first cleaned with Purified Water to remove water‐soluble residues. Immediately thereafter, the same surfaces are sanitized with sterile 70% isopropyl alcohol, or other effective disinfectant, using a non‐lint wipe. Alcohol should be allowed to air dry. Caution: USE OF CHLORINATED OR HALOGEN MATERIALS IN THE ISOLATOR MAY DAMAGE STAINLESS STEEL.
6.3.3
Materials & Equipment The apparatus and materials should next be placed into the Isolator. If the hinged window is opened for material installation and additional 5 minutes of run time is required to purge the work zone from contaminants. All normal work material should enter via the exterior and interior doors. At no time should both doors be open simultaneously. All materials should be staged away from the Isolator, shipping containers, and cardboard discarded. The materials should then be brought over to the Isolator via a dedicated cart or other material moving device. Then open the exterior door, move materials into the interchange area and remove final packaging using the unidirectional or first air and wipe down materials as they are placed on the interchange slide tray. Note: certain syringe designs require an aseptic connection immediately upon removal from the wrapper. These units are to be removed from the wrapper after placement in the main chamber. Once all the materials are placed into the interchange chamber, close the exterior door, open interior door and pull the slide tray into the main working chamber.

6.3.4
Perform Work The work can now be performed. a. After proper introduction into the Isolator of supply items required for and limited to the assigned operations, they are so arranged that a clear, uninterrupted path of HEPA‐filtered air will bathe all critical sites at all times during the planned procedures. That is, no objects may be place behind an exposed critical site in a horizontal position or above an exposed critical site in a vertical position. b. If totes, plastic bags, or transport bags are used for material handling, these items should not be brought into the main chamber. These items should be left on the slide tray to minimize the potential for contamination. c. All supply items are arranged in the Isolator to reduce clutter and to provide maximum efficiency and order for the flow of work. Assign operations so they are arranged that a clear, uninterrupted path of unidirectional or “first air” will bathe all critical sites at all times during the planned procedures. d. All procedures are performed in a manner designed to minimize the risk of touch contamination. Gloves are sanitized with adequate frequency with an approved disinfectant. e. All rubber stoppers of vials and bottles and the neck of ampuls are sanitized with 70% isopropyl alcohol before the introduction of a needle or spike for the removal of product. f. After the preparations of every admixture, the contents of the container are thoroughly mixed and then inspected for the presence of particulate matter, evidence of incompatibility, or other defects. g. After procedures are completed, used syringes, bottles, vials, and other supplies are removed or discarded, but with a minimum of exit and re‐entry into the Isolator to minimize the risk of introducing contamination into the aseptic work space.
6.3.5
Terminal Purging & Wipedown Following completion of work, allows the Isolator to run for 2‐3 minute period without personnel activity to purge the unit. The decontamination of the interior surfaces should be repeated after removal of all materials, etc. A careful check of grills and diffuser grids should be made for spilled or splashed nutrients, which may support fungus growth, and resulting spore liberation that contaminates the protected work environment.
6.3.6
6.3.7
Paper Catch A permanent paper catch is installed behind the rear divider panel of the work zone. This area forms the return air path to the motor/blower; and if the airflow is blocked, it could seriously affect the performance of the Isolator. Therefore, THE PAPER CATCH SHOULD BE CHECKED ON A ROUTINE basis if procedures dictate the use of paper products. Any paper removed must be properly disposed. Prefilters Located on top of the Isolator, toward the front is a prefilter combination. This area forms the air path to the supply motor/blower. If the air flow is blocked by excessive buildup of particulate the performance of the cabinet could be seriously affected. Therefore, THE PREFILTERS SHOULD BE CHECKED AND CLEANED NO LESS THAN ON A MONTHLY BASIS. The top prefilter may be vacuumed to remove particulate debris. Both prefilters may be replaced as necessary (see replacement parts list). In order for the Isolator to function properly, ! the correct prefilters must be in place. Exhaust Filter Located on top of the Isolator, toward the back is an exhaust filter. If the airflow is blocked by excessive buildup of particulate, the cabinet will increase in pressure and will increase in temperature. The flow control plate located beneath the exhaust filter can be opened to decrease the pressure in the cabinet and to reduce the temperature. This filter should be checked no less than twice a year. The exhaust filter may be replaced as necessary (see Replacement Parts List).

6.4 Ergonomics Ergonomics, the study, or accommodation of work practices is extremely important for proper Isolator usage and user health and safety. An evaluation of normal work practices should be performed with each user when working in an Isolator. Evaluation criteria should be at a minimum: a. Proper user posture b. Effective work zone layout for work practice c. Vision or sightlines For each of the above evaluation criterion, several aids may be supplied to accommodate the user. Ergonomic chair ‐ A six‐way articulating seat and back control for personalized adjustment to assure proper user posture. Be sure feet are resting on the floor, chair foot support or foot rest. Also, be sure back is fully supported with proper chair adjustments. Forearm/armrest support ‐ The Isolator is provided with glove ports that provide forearm support. Periodic mini‐ breaks during work practice should be taken resting forearm to avoid stress and fatigue. Effective work zone layout ‐ Always prepare your work procedure to minimize reach to avoid neck and shoulder stress and fatigue. Rotating tables are optional to maximum work zone and minimize reach. Vision and sightline ‐ Always prepare your work procedure to eliminate glare and bright reflections on the window. Keep your window clean and sightlines clear to your effect work zone.
NuAire offers many ergonomic aids. Please visit our on‐line store website at www.scientificvisions.com. 6.5 Cleaning Procedures Cleaning the Isolator is an important function in terms of sterility. Use the following procedure to effectively clean or surface disinfect the Isolator work zone surfaces. Cleaning under the worksurface and checking the paper catch should be performed on a routine basis depending upon product usage. High use could be as frequent as monthly with low usage extended out to quarterly. Remember to document all cleaning activities per Standard Operating Procedures (SOP’s) of your facility.
a. Either raise the hinged window to a full‐open position or leave closed cleaning through the gloves. b. Apply appropriate disinfecting solution to Isolator surfaces. Most surface disinfectants require a specific contact time. CONSULT APPROPRIATE DISINFECTANT DOCUMENTATION FOR PROPER APPLICATION AND SAFETY PRECAUTIONS. Use soft lint free wipes for wiping process Recommended cleaners for polycarbonates are: Formula 409 (for external surfaces only) Windex D w/Ammonia D (for external surfaces only) 70% Isopropyl Alcohol The use of polycarbonate has some important don’ts: Do Not use abrasive or high alkaline cleaners Do Not scrape with squeegees, razor blades, or other sharp instruments. Please refer to section 12.0 for Polycarbonate material compatibility. NOTE: DISINFECTANTS THAT USE CHLORIDES AND HALOGENS WILL CAUSE DAMAGE TO THE STAINLESS STEEL SURFACES IF LEFT ON FOR LONG PERIODS OF TIME.
c.
After the specified contact time, wipe up excess disinfectant. IF THE DISINFECTANT USED CONTAINS CHLORIDES OR HALOGENS, RE‐WIPE ALL SURFACES WITH 70% ISOPROPYL ALCOHOL OR SIMILAR NON‐CORROSIVE ANTI‐ MICROBIAL AGENT TO REMOVE CHLORIDES OR HALOGENS PREVENING DAMAGE TO STAINLESS STEEL SURFACES.
OM0189 September/2014

6.6
Sleeve/Glove Usage The Pharmagard Isolator utilizes Nitrile sleeves and gloves. Nitrile, which is known as Butadiene Acrylonitrile, is made as a synthetic polymer. Nitrile offers great properties for both sleeve and glove application. Nitrile: is flexible and shows outstanding tensile and compression stress qualities; offers strong resistance to most aromatic hydrocarbons, petroleum solvents, oils, fats, acids, and greases; is recommended for ethanol, gasoline, hexane, isopropanol, turpentine, and xylene; is not prone to induce allergic reactions; dissipates electrostatic charge as well; resists puncture and offers excellent abrasion protection; The NU‐PR797 utilizes a smooth sleeve configuration for cleanability. In addition, the glove can be removed from the sleeve, as well as the sleeve can be removed from the glove port. (See BCD‐10484 for sleeve/glove replacement procedure.)
Depending upon Isolator usage, NuAire typically recommends sleeve/glove replacement on the following schedule: Sleeves – Once every six months Gloves ‐ Once per week Of course, sleeve/glove replacement is largely dependent upon usage and wear, so more frequent replacement may be necessary. Reference ASHP and NIOSH for additional guidance documents. The NuAire selection of gloves provided on the Isolator was based on general usage, type, cost and availability. Other glove types may be used if desired or found to perform better for CAI users. At a minimum, the gloves should be at least 6 mils thick, sterile, power‐free, either ambidextrous or form fit being at least 12 inches long. For NuAire NU‐797 Isolator replacement gloves/sleeves, see insert.

Airflow Calibration !
Failure to calibrate airflow to the specified requirements may result in unsafe conditions of performance (i.e. product and/or personnel protection, noise and vibration)
CAUTION
The NU‐PR797 airflow calibration consists of adjustments to balance the airflow within the Isolator. THIS WORK SHOULD BE DONE ONLY BY A QUALIFIED TECHNICIAN WHO CAN MEASURE THE AIRFLOW FROM THE FILTERS WITH A SUITABLE VELOMETER. NuAire provides one adjustment to calibrate the airflow within the Isolator. This is: a. The supply airflow PWM signal, adjust via DC Motor Speed Control. Motor/blower PWM signal DC voltage should also be monitored and recorded upon final calibration. The motor voltage may be monitored using a digital voltmeter. The two test points to measure supply PWM signal voltage are located on the main control module (see sketch below). Supply Blower Speed Adjustments at P26 and/or P28

PWM signal test points (0 ‐ 10 Vdc) are Black‐Red from P28 and or P26. It may be easiest to measure this signal by following the cable to the bulkhead connector above the supply HEPA filter access panel. b. Recirculating air inside the Isolator can impact the pressure and temperature of the Isolator. This can be adjusted by the flow control plate, which can be accessed by removing the exhaust filter on top of the Isolator.
The Isolator is considered to be certifiable if the following airflow measurements are present: a. Downflow Average: 35 fpm (.18 m/s) minimum. b. Isolator Pressure: Work zone: 0.15" w.g. minimum Interchange: 0.10" w.g. minimum, and at least .05” w.g. lower than workzone pressure. BEFORE STARTING AIRFLOW CALIBRATION PROCEDURE, LET THE ISOLATOR RUN FOR AT LEAST 10 MINUTES. 7.5.1 Downflow Calibration Step 1: Raise hinged window to access workzone and place a velometer in the Isolator work zone on the horizontal plane 6 inches (152mm) from the supply diffuser. Spot check several points on the recommended downflow velocity test grid found in table 7.0. Step 2: If necessary, adjust airflow control potentiometer, located on the main control module in the control center to the above stated airflow requirements. Step 3: Proceed to pressure calibration.
OM0189 September/2014
Page 27 of 43
7.5.2
Adjustment of Differential Pressure between Main Workzone Chamber and Interchange Chamber The pressure in the interchange chamber should be maintained at .05”w.g. lower than the pressure in the main workzone chamber. This pressure differential can be adjusted by changing the position of the slide baffle beneath the interchange worktray. If a greater differential pressure is needed, then loosen the fasteners and slide the baffle beneath the worktray. If a smaller differential pressure is needed than slide the baffle out from the worktray. Be sure to tighten the fasteners before returning to operation of the unit. Note: The minihelic gauge should be periodically checked for its zero reading. If the zero reading has drifted, re‐zeroing is accomplished by unscrewing the front cover counterclockwise using a small sheet of rubber between the cover and the palm of the hand. Once the cover is removed, the zero‐adjust screw is located behind the scale at the pair marked “zero”. Use the hex Allen wrench provided (located in control center) and adjust until pointer is on zero. This must be done with the cabinet blower off and the control panel in its normal position. Once adjusted, replace cover.
7.6 Filter Integrity Check In order to check filter and filter seal integrity, the HEPA filter media and seals must be directly accessible, by the measuring instrument. The challenge material (i.e. PAO) should be supplied in the rear center of the workzone over the intake slots.
The diffuser plate placed below the HEPA to protect the filter during normal usage may be removed as follows: The diffuser is secured to the Isolator shell by #1/4‐20 acorn nuts located immediately behind the front viewing window. After removing the fasteners, drop the front of the diffuser plate several inches and pull forward gently. Note that the diffuser is purposely a tight fit ‐ it is secured to the back wall of the Isolator interior by a light push ‐ fit with projecting studs. The intake filter does not require testing, since the airflow will be taken directly into the supply HEPA filter. The exhaust filter does not require testing on the positive pressure Isolator either. Table 7.0 Recommended Measurement Methods for Isolator Downflow Downflow Measurement a. Recommended Instruments: TSI 8355 Thermo anemometer b. Procedure: Downflow velocities are measured on a grid; in a horizontal plane 6 inches (152mm) below the supply filter diffuser. No readings should be taken closer than 6 inches (152mm) from the inside perimeter. Downflow velocities are typically taken with the hinged window open. However, downflow velocities can be also taken with the hinged window closed. In the closed position, downflow average velocities readings will be approximately 10% less than in the open position due to unidirectional airflow restriction of the Thermoanemometer reading, but still well above the minimum average downflow requirement. c. Test Data ‐ Inches (mm): 400 6 11.81 17.62 23.43 29.25 (152) (300) (448) (595) (743) 600 6 11.91 17.82 23.73 29.64 35.55 41.46 47.37 53.25 (152) (303) (453) (663) (753) (903) (1053) (1203) (1353) 6 (152) 10 (254) 14 (356)
Number of Readings: Average Velocity ft./min. (m/s) d. Acceptance Criteria: 1. Average downflow velocity > 35 fpm (.18 m/s) minimum. 2. Individual readings must be within +20 percent (factory) + 25% (field) or + 16 fpm of the average downflow velocity whichever is greater. 7.7 Cleanliness Classification Test OM0189 September/2014
Page 28 of 43
7.8
7.9
The Isolator cleanliness classification test is performed to assure compliance to ISO 14644‐1, Cleanrooms and Associated Controlled Environments, Part 1: Classification of Air Cleanliness. The cleanliness classification test is performed using a particle counter to measure particle counts within the Isolator workzone. The particle count process would be to connect the input tubing to the test port provided on the Isolator both inside with several feet of tubing/sampling cone and outside. Turn on Isolator and let warm up for several minutes. Turn on particle counter and flush out sample tubing line to remove latent particles. Set the particle counter to measure 0.5 micron or larger particles at the appropriate measuring rate. Take 5 test points in 1‐minute intervals on a grid in a horizontal plane as measured by the centerpoint of the glove ports. The grid location is designated as the workzone centerpoint and each corner measured 6‐inches (152mm) from the inside perimeter. Record the 5 particle count values for each of the test points over the 1‐minute sample time. All final count values shall be less than 100 particles per cubic feet (ppcf) or 3520 particles per cubic meter (ppcm). Enclosure Integrity Test The Isolator enclosure integrity test is performed to verify that no contamination entry points exist within the Isolator workzone. The enclosure integrity test is performed using a particle counter to measure particle counts within the Isolator workzone in specific locations, i.e. window seal, glove port, sleeves and gloves. The particle count process would be to connect the input tubing to the test port provided on the Isolator both inside with several feet of tubing/sampling cone and outside. Turn on Isolator and let warm up for several minutes. Turn on particle counter and flush out sample tubing line to remove latent particles. Set the particle counter to measure 0.5 micron or larger particles at the appropriate measuring rate. Scan all areas as described below in 1‐minutes intervals. 1 inch from entire perimeter of hinged window gasket area. 1 inch from perimeter of glove ports, sleeves and gloves. 1 inch from internal interchange door perimeter seal. Record particle count values for each of the areas over the 1‐minute sample time. During the scanning process, a momentary surge or spike of particle counts may be an indication of particle intrusion and must be investigated and corrected. All final count values shall be less than 100 ppcf or 3520 ppcm. Main Control Board Description & Replacement The main control board consists of one Printed Circuit Board (PCB) assembly. The assembly consists of a power supply, relay logic and an independent motor speed control. CAUTION: Disconnect electrical power from the unit before attempting any maintenance action. The main control board is fastened to the control center with (6) 6‐32 studs, lockwashers and nuts. All electrical connections are made with removable terminals and/or Faston connectors. All AC circuits are fuse protected and when replacement is necessary, USE ONLY FUSES OF SAME TYPE AND RATING FOR PROTECTION AGAINST RISK OF FIRE.

Optional Equipment
10.1 Pharmagard Digital Monitor
10.1.1 General The Pharmagard Digital Monitor uses an integrated digital pressure transducer to monitor positive pressure. The monitor indicates through both a segment display and LED’s. The segment display is green and operates to + 0.01” w.g. sensitivity. The LED’s indicate acceptable pressure (green), caution or near alarm points to within 0.005” w.g. (yellow) or alarm condition (red). The monitor starts when the Isolator blower is turned on. Upon start up, all segments displays, and LED’s will light and a short audible alarm will sound to indicate a properly functioning monitor. During the next 4 minutes, the segment display will indicate dashes and green LED will blink during the warm‐up period. Once the 4‐minute warm‐up period is complete, the monitor will measure and display the current main workzone chamber pressure. If the monitor is not functioning properly, the green, yellow and red LED’s will blink to indicate an error. During external door openings, the Isolator’s pressure will decrease. The monitor will display the low setpoint and indicate a pending alarm. This will initiate a 60 second audible alarm delay for material movement purposes. If the Isolator pressure remains low for more than 60 seconds, the audible alarm will sound. The monitor is powered by 24 VAC supplied from the main control board. The monitor also has alarm contacts, COM, NO, NC for external monitoring. All user interaction is accomplished through the arrow and reset keys. It is recommended that the monitor be calibrated during the certification process.

Nominal Pressure Calibration The Pharmagard Digital Monitor is factory calibrated to match the main workzone chamber minihelic gauge pressure value. This is accomplished through an offset calibration procedure. To accomplish, perform the following once the Isolator has been certified to its proper airflow and the monitor is through the warm‐up period. Press and hold [] and [] arrow key simultaneously for 3 seconds until the red LED blinks and the display alternates “In” and a pressure value. Use [] and [] arrow keys to adjust the display value to match the main workzone chamber pressure minihelic gauge. Press [RESET] key to enter the nominal pressure value (red LED will stop blinking and display will indicate pressure value). High/Low Alarm Setpoint Calibration The Pharmagard Digital Monitor is factory calibrated to 0.10” w.g. low and 0.50” w.g. high. To verify or to change the alarm setpoints, perform the following procedure. Press and hold either [] key for high alarm or [] key for low alarm for 3 seconds until the red LED blinks and the display alternates either “Hi” or “Lo” and a pressure value. Use [] and [] arrow keys to adjust the display value desired. Press [RESET] key to enter the alarm setpoint value. Audible alarm The audible alarm should be activated whenever the pressure reaches the high or low alarm setpoint. However, once the alarm pressure is reached, it must stay on the alarm limit foe 5 seconds consistently or it will not recognize it as an alarm. If at any time, the pressure returns to acceptable limits, the alarm would be reset and silenced. Once the 5 second period of constant alarm is present, the audible should sound for 30 seconds, then ring back 1 second every 10 seconds. If the [RESET] key is pressed, the alarm should be silenced for 5 minutes, then continue to ring back for 1 second every 10.

10.2 Sharps/Garbage Disposal System for Non‐Hazardous Drugs 10.2.1 General (BCD‐13592) The Sharps/garbage disposal system for non‐hazardous drugs provides a unique method to dispose of Sharps and waste material within the Isolator during the Compounding Sterile Product (CSP) preparation process. The waste chute is designed with a large sealed stainless steel (SST) tube that extends from the worksurface to just under the bottom of the Isolator. The SST tube is covered within the workzone with a machined plastic stopper with a post to push wrapper materials down into the Sharps container. The Sharps container is located directly under the SST tube and held in place with a hinged platform. The Sharps containers top opening is inserted into the SST tube and sealed with a ring gasket as it is pushed up tight against the bottom of the Isolator. The Sharps container is locked into position with a spring lock handle. The Sharps container contents cannot be emptied once full. Upon removing a full Sharps container, the transport lid should be placed over the top opening and disposed of through the proper procedures of the facility. NuAire utilizes BD medical system Sharps containers and may be reordered through the NuAire on‐line store, www.scientificvisions.com, or any BD medical system distributor.
