Before Using Your Vacuum Pump In all cases, motors are designed for operating voltages plus or minus 10% of the normal rating. Single voltage motors are supplied fully connected and ready to operate. 1. Check to be sure the voltage and frequency at the outlet match the specifications on the pump motor decal. Check the ON-OFF switch to make sure it is in the OFF Position before you plug the pump into an outlet. Check to be sure the gas ballast valve is closed. Remove and discard the exhaust plug from the end of the pump’s handle. 2. The pump is shipped without oil in the reservoir. Before starting the pump, fill it with oil. Remove the OIL FILL Cap and add oil until oil just shows in the bottom of the sight glass. The approximate oil capacity of the pump is between 6.1 oz. and 20 oz. Depending on the size of the pump. (Reference the Table in Section 5 Technical Data for your specific requirements).

Pump explosion Before Using Your Vacuum Pump, continued 3. Replace the OIL FILL Cap and remove the cap from one of the inlet ports. Turn the motor switch to ON. When the pump runs smoothly, replace the cap on the inlet port. This may take from two to 30 seconds depending on the ambient temperature. After the pump runs for approximately one minute, check the sight glass to ensure proper oil level. Oil in sight glass should be even with the SIGHT GLASS OIL LEVEL line. Add oil if necessary. Note: When the pump is running, the oil level should be even with the line on the sight glass. Under filling will result in poor vacuum performance. Over filling can result in oil blowing from the exhaust.

During Operation The Valu-Vac series is manufactured with an internal breaker that shuts down the pump to prevent overheating. It is generally recommended that you shut down your pump after every 4-6 hours of usage to allow for cooling of the unit. Warning Do not run pump open to direct air for more than 3 minutes as sever damage may occur. Shutting Down Your Vacuum Pump After Use To help prolong pump life and promote easy starting, follow these procedures for shut down. 1. Close the manifold valve between the pump and the system. 2. Remove the hose from the pump inlet. 3. Cap the inlet port to prevent any contamination or loose particles from entering the port.

Maintenance

Vacuum pump accessories continued

Vacuum Pump Oil The condition and type of oil used in any high vacuum pump are extremely important in determining the ultimate attainable vacuum. We recommend the use of Model #5000 Super X Premium Vacuum Pump Oil. This oil has been specifically blended to maintain maximum viscosity at normal running temperatures and to improve cold weather starts.

Manifolds Thermal Engineering is proud to re-introduce its side wheel charging manifold. Its features include floating valve stems, forged brass construction, hose holders, chrome plated hanging hooks, and charging line sight glass. The right manifold for the right price!

Oil Change Procedure 1. Be sure the pump is warmed up. 2. Remove the OIL DRAIN cap. Drain contaminated oil into a suitable container and dispose of properly. Oil can be forced from the pump by opening the inlet and partially blocking the exhaust with a cloth while the pump is running. Do not operate the pump for more than 20 seconds using this method. 3. When the flow of oil has stopped, tilt the pump forward to drain residual oil. 4. Replace the OIL DRAIN cap. Remove the OIL FILL cap and fill the reservoir with new vacuum pump oil until the oil just shows at the bottom of the sight glass. The approximate oil capacity of the pump is 6-20oz. (reference the technical data). 5. Be sure the inlet ports are capped, then turn on the pump and allow it to run for one minute, then check the oil level. If the oil is below the SIGHT GLASS OIL LEVEL line; add oil slowly (with the pump running) until the oil reaches the SIGHT GLASS OIL LEVEL line. Replace the OIL FILL cap, making sure the inlet is capped and the drain cap is tight. 6. a) If the oil is badly contaminated with sludge that forms when water is allowed to collect in the oil, you may need to remove the oil reservoir cover and wipe it out. b) Another method of dealing with heavily contaminated oil is to force the oil from the pump reservoir. To do this, allow the pump to run until it is warmed up. While the pump is still running, remove the oil drain cap. Slightly restrict the exhaust. This will back-pressure the oil reservoir and forces the oil from it, carrying more contaminants. When the oil ceases to flow, turn off the pump. Repeat this procedure as required until the contamination is removed. Replace the OIL DRAIN cap and refill the reservoir to the proper level with fresh pump oil. 3

5000 Vacuum Pump Oil Airserco Super-X Vacuum Pump Oil keeps any high vacuum pump at maximum performance. No pump can deliver a lower pressure than its sealing oil’s vapor pressure. This oil must have the viscosity to lubricate and seal clearances in the pump’s moving parts at the extreme temperatures developed during continuous use. Super-X oil is a premium quality mineral oil formulated to tolerate exposure to vacuums of 5 microns. Super-X oil resists the formation of deposits and maintains its original lubricating properties over a long life. Super-X offers very high vacuums, excellent lubrication, and long oil life. Available in 1 gallon plastic containers, 4 per case, or 1 quart bottles, 12 per case. Super-X Oil Typical Characteristics Gravity, API: 29.2 Viscosity: SUS at 100°F 335 Flash Point: 450°F Pressure, microns, Hg, max: 5 Tru Pro Charging Hoses For those interested in premium quality, the Thermal Engineering Tru Pro Series refrigerant charge hose is the only choice. Made in the USA, these hose assemblies conform to UL 1963, SAE J-51, J-639, J-2196, and J-2197. With 4000psi minimum burst and a working pressure 800psi these hoses are long lasting, durable, and come in a range of options to meet your specific requirements.

Troubleshooting Your pump has been designed for dependable use and long life. If something should go wrong, however, the following guide will help you get the pump back into service as quickly as possible. If disassembly of the pump is required, please check your warranty. The warranty may be voided by misuse or customer tampering which results in the pump being inoperable. Failure To Start Check the line voltage. The pumps are designed to start at ±10% line voltage (loaded) at 32˚F. At extremes, however, switching between the start and run windings may occur. Oil Leakage 1. Be sure the oil is not a residual accumulation from spillage, etc. 2. If leakage exists, the module cover gasket or the shaft seal may need replacing. If leakage exists in the area of the oil drain plug, you may need to reseal the plug using a commercial pipe thread sealer. Failure To Pull A Good Vacuum 1. Be sure the vacuum gauge and all connections are in good condition and leak-free. You can confirm leakage by monitoring the vacuum with a thermistor gauge while applying vacuum pump oil at connections or suspected leak points. The vacuum will improve briefly while the oil is sealing the leak. 2. Be sure the pump oil is clean. A badly contaminated pump may require several oil flushes. 3. Be sure the oil is at the proper level. For maximum pump operation, the oil must be even with the OIL LEVEL line on the sight glass when the pump is running. Do not overfill – operating temperatures will cause the oil to expand so it will appear at a higher level than when the pump is not running. To check the oil level, start the pump with the inlet capped, check the oil level in the sight glass. Add oil if necessary.
