IMPORTANT NOTICE

 DANGER:

- Pressure Vessel and Safety Device: This air conditioner is equipped with a high pressure vessel under PED (Pressure Equipment Directive). The pressure vessel has been designed and tested before shipment according to PED. Also, in order to prevent the system from an abnormal pressure, a high pressure switch, which needs no field adjustment, is utilized in the refrigeration system. Therefore, this air conditioner is protected from abnormal pressures. However, if abnormally high pressure is applied to the refrigeration cycle including the high pressure vessel(s), it will result in serious injury or death due to explosion of the pressure vessel. Do not apply a pressure higher than the following pressure to the system, by modifying or changing the high pressure switch.

- Start-up and Operation: Check to ensure that all the stop valves are fully opened and no obstacle exists at the inlet/outlet sides before start-up and during the operation. - Maintenance: Periodically check the high pressure side pressure. If the pressure is higher than the maximum allowable pressure, stop the system and clean the heat exchanger or remove the cause.

SYSTEM DESCRIPTION

3. SYSTEM DESCRIPTION ■■ Long piping for high-rise buildings. ■■ Flexibility of indoor unit control. ■■ Space saving. ■■ Easy installation.

 NOTE:

For more information refer to indoor unit installation and operation manual PMML0208A(RWM-(8.0/10.0)FSN3E) or PMML0257A(RWM-(8.0/10.0)HFSN3E).

4. BEFORE OPERATION

 CAUTION:

- Supply electrical power to the system for approximately 12 hours before start-up or a long shutdown. Do not start the system immediately after power supply, it may cause a compressor is not heated well. - When the system is started after a shutdown longer that approximately 3 months, it is recommended to check the system by your service contractor.

- Turn OFF the main switch when the system is to be stopped for a long period of time: If the main switch is not turned OFF, electricity will be used, because the oil heater is always energised during compressor stopping. - Make sure that the outdoor unit is not covered with snow or ice. If covered, remove it by using hot water (approximately 50 ºC). If the water temperature is higher that 50 ºC, it will cause damage to plastic parts.

AUTOMATIC CONTROLS

5. AUTOMATIC CONTROLS The system is equipped with the following functions:

■■

THREE MINUTE GUARD The compressor remains off for at least 3 minutes once it has stopped. If the system is started within approximately 3 minutes after it has stopped, the RUN indicator is activated. However, the cooling operation or the heating operation remains off and does not start until after 3 minutes has elapsed.

■■

FROST PREVENTION DURING COOLING OPERATION When the system is operated in a low temperature room, the cooling operation may be changed to fan operation for a while to avoid frost formation on the indoor heat exchanger.

■■

AUTOMATIC RESTART AFTER POWER FAILURE If the power supply is interrupted for short periods of time (up to 2 seconds) the Remote Control switch will retain the settings and the unit will restart when the power is restored. If Automatic Restart is required after periods of lost power supply in excess of 2 seconds please contact your distributor (optional function).

■■

SLOW AIR CONTROL DURING HEATING OPERATION When the compressor is stopped while the thermostat is OFF, or the system is performing the automatic defrosting operation, the fan speed is set at the slow position or stop.

■■

AUTOMATIC DEFROSTING CYCLE When the heating operation is stopped by pressing RUN/STOP switch, frosting on the outdoor unit is checked and the defrosting operation may be performed for the maximum of 10 minutes.

■■

PREVENTION OF OVERLOAD OPERATION When the outdoor temperature is too high during heating operation, heating operation is stopped due to activation of the outdoor thermistor until the temperature becomes low.

■■

HOT START DURING HEATING OPERATION To prevent cold air discharge, the fan speed is controlled from the slow position to the set position according to the discharge air temperature. At this time the louver is fixed horizontally.

■■

COMPRESSOR HOT START RAS-8~10 HRNME-AF Series does not operate within 4 hours after power supply (stopagge code d1-22). In case of operating within 4 hours, see “Test Run” chapter.

6. BASIC TROUBLESCHOOTING

 CAUTION:

When you smell or white smoke occurs from the unit, stop the system and contact your contractor.

■■ THIS IS NOT ABNORMAL

■■ Sound from deforming Part During system starting or stopping, and abrading sound might be heard. However, this is due to thermal deformation of plastic parts. It is not abnormal. ■■ Refrigerant Flow Sound While the system is being started or stopping, sound from the refrigerant flow may be heard. ■■ Steam from Outdoor Heat Exchanger During defrosting operation, ice on the outdoor heat exchanger is melted, resulting in making steam. ■■ Dew on Cabinet When the cooling operation continues for a long period of timer (higher than 27ºC DB/80% R.H.), dew can form on the cabinet.

■■ NO OPERATION

Check whether the SET TEMPERATURE is set at the correct temperature.

18

PMML0215A rev.1 - 02/2012

■■ NOT COOLING WELL OR HEATING WELL

■■ Check for obstruction of air flow of the outside or inside units. ■■ Check if too much heat source exists in the room. ■■ Check if the air filter is clogged with dust. ■■ Check to see if the doors or windows are opened or not. ■■ Check if the temperature condition is not within the operating range.

■■ IF TROUBLE STILL REMAINS...

If the trouble still remains even after checking the above items, contact your service contractor and inform the following data: Unit Model Name Content of Trouble Alarm Code no. on Liquid Crystal Display

 CAUTION:

- Use refrigerant R410A in the refrigerant cycle. Do not charge oxygen, acetylene or other flammable and poisonous gases into the refrigerant cycle when performing a leakage test or an air-tight test. - These types of gases are extremely dangerous and can cause an explosion. It is recommended that compressed air, nitrogen or refrigerant be used for these types of tests. - Check to ensure that no pressure exists inside the stop valve before removing the flange.

Outdoor Unit

Charging Cylinder

Gas Stop valve Liquid Stop valve

■■ Evacuation and Refrigerant Charge Evacuation and refrigerant charging procedure should be performed according to the following instructions. The stop valve has been closed before shipment. However, make sure that the stop valves are closed completely. Connect the indoor unit and the outdoor unit with field-supplied refrigerant piping. Suspend the refrigerant piping at certain points and prevent the refrigerant piping from touching the weak part of the building such as wall, ceiling, etc., (If touched, abnormal sound may occur due to the vibration of the piping. Pay special attention in case of short piping length) Apply refrigerant oil thinly to the seat surface of flare nuts and pipe before tightening. Connect the gauge manifold using charging hoses with a vacuum pump or a nitrogen cylinder to the check joints of the liquid line and the gas line stop valve. Check for any gas leakage at the flare nut connection, by using nitrogen gas to increase the pressure at 4.15MPa for HRNME outdoor units inside of the field-supplied piping. Operate the vacuum pump for 1 to 2 hours until the pressure decreases lower than a pressure of 756 mmHg in vacuum. For charging refrigerant, connect the gauge manifold using charging hoses with a refrigerant charging cylinder to the check joint of the liquid line stop valve. Charge the proper quantity of refrigerant according to the piping length (Calculate the quantity of the refrigerant charge). Fully open the gas line stop valve, and slightly open the liquid line stop valve. Charge refrigerant by opening the gauge manifold valve. Charge the required refrigerant within the difference range of ±0.5kg by operating the system in cooling. Fully open the liquid line stop valve after completing refrigerant charge. Continue cooling operation for more than 10 minutes to circulate the refrigerant. Remove the “close” plate from the stop valve and hook the attached “Open” plate at the stop valve.

 NOTE:

- Charge the refrigerant correctly after calculation.

Overcharge and insufficient charge of the refrigerant may cause the compressor failure. Insulate the liquid pipe for prevention of the capacity decrease according to the ambient air conditions and the dewing on the pipe surface by the low pressure. - Check to ensure that there is no gas leakage. When large amount of the refrigerant leaks, the troubles as follows may occur: - Oxygen deficiency - Generation of Harmful gas Due to Chemical Reaction with fire. - Use thick gloves to protect your hands from liquid refrigerant injuries when handling refrigerant.

 CAUTION:

Check for refrigerant leakage in detail. If a large refrigerant leakage occurs, it will cause difficulty with breathing or harmful gases would occur if a fire was being used in the room. An excess or a shortage of refrigerant is the main cause of trouble to the units. Charge the correct refrigerant quantity.

 CAUTION:

1. Prepare locally-supplied copper pipes. 2. Select the piping size with the correct thickness and correct material which can have sufficient pressure strength. 3. Select clean copper pipes. Make sure there is no dust and moisture inside. Blow the inside of the pipes with oxygen free nitrogen to remove any dust and foreign materials before connecting pipes. 4. After connecting the refrigerant piping, seal the open space between Knockout hole and refrigerant pipes by using insulation material as shown bellow: Insulation material Field-Supplied Unit Side

Insulation material

Insulation material

NOTE:

A system with no moisture or oil contamination will give maximum performance and lifecycle compared to that of a poorly prepared system. Take particular care to ensure all copper piping is clean and dry internally. There is no refrigerant in the cycle of the indoor unit.

Cap the end of the pipe when pipe is to be inserted through a hole. Do not put pipes on the ground directly without a cap or vinyl tape at the end of the pipe.

If piping installation is not completed until next day or over a longer period of time, braze off the ends of the piping and charge with oxygen free nitrogen through a Schrader valve type access fitting to prevent moisture and particle contamination. Do not use insulation material that contains NH3 because it can damage cooper pipe material and can be a source of future leakage. Completely insulate both refrigerant gas piping and liquid piping between the indoor unit(s) and the outdoor unit. If not insulated, dew will ocur on the piping surface.

10.1.2. SUSPENSION OF REFRIGERANT PIPING Suspend the refrigerant piping at certain points and prevent the refrigerant piping from touching the weak part of the building such as wall, ceiling, etc. (If touched, abnormal sound may occur due to the vibration of the piping.

Caution on Refrigerant Leakage Specifiers/installers have responsibility to follow local codes and regulation which specify safety requirements against refrigerant leakage. Maximum Permissible Concentration of HCFC/HFC Gas The refrigerant R410A, charged in the HRNME system, is an incombustible and non-toxic gas. However, if leakage occurs and gas fills a room, it may cause suffocation. The maximum permissible concentration of HCFC/HFC gas, R410A in air is 0.44 kg/m³, according to EN378-1 Therefore, some effective measure must be taken to lower the R410A concentration in air below 0.44 kg/m³, in case of leakage.

If not, some component will be damaged. Follow local codes and regulations when performing electrical wiring. Use twisted shielded pair wiring for operation wiring between outdoor unit and indoor unit, and also for operation wiring between indoor units (H-Link connection)

It can be also used Shielded pair wiring. Shield shall be connected to earth only in one cable side. Do not use more than 3 cores for operation wiring (-H-Link). Core sizes must be selected according to the national regulations. Open a hole near the connection hole of power source wiring when multiple outdoor units are connected from one power source line. The recommended breaker sizes are shown in Table of electrical data and recommended Wiring, Breaker Size/1 O.U. In the case that a conduit tube for field-wiring is not used, fix rubber bushes with adhesive on the panel. All the field wiring and equipment must comply with local and international codes.

TEST RUNNING

13. TEST RUNNING When installation is completed, perform test run according to the following procedure, and hand over the system to the customer. Perform test run regarding indoor units one by one in order, and confirm that the electrical wiring and the refrigerant piping are correctly connected. Test run should be performed according to the Test Run Procedure on next page.

 WARNING ■■ Do not operate the system until all the check points have been cleared: - Check to ensure that the electrical resistance is more than 1 MΩ, by measuring the resistance between ground and the terminal of the electrical parts. If not, do not operate the system until the electrical leakage is found and repaired. Do not impress the voltage on the terminals for transmission 1 and 2. - Check to ensure that the stop valves of the outdoor unit are fully opened, and then start the system. - Check to ensure that the switch on the main power source has been ON for more than 12 hours, to warm the compressor oil by the oil heater. ■■ Pay attention to the following items while the system is running: - Do not touch any of the parts by hand at the discharge gas side, since the compressor chamber and the pipes at the discharge side are heated higher than 90°C. - DO NOT PUSH THE BUTTON OF THE MAGNETIC SWITCH(ES), it will cause a serious accident. ■■ Do not touch any electrical components for more than three minutes after turning OFF the main switch.

■■ Confirm that the gas line stop valve and the liquid line stop valve are fully open. ■■ Confirm that the leakage of the refrigerant does not exist. The flare nuts are sometimes loosened by vibration during transportation. ■■ Check that the refrigerant piping and the electrical wiring conform to the same system. ■■ Confirm that the dip switch setting on the printed circuit board of the indoor units and the outdoor units are correct. ■■ Check whether or not the electrical wiring of the indoor units and the outdoor units are connected as shown in the chapter ELECTRICAL WIRING.

 CAUTION:

Confirm that field-supplied electrical components (main switch fuse, fuse-free breaker, earthleakage breakers, wires, conduit connectors and wire terminals) have been properly selected according to the electrical data given in the Technical Catalog of the unit and ensure that the components comply with national and local codes.
