Troubleshooting Guide Your pump has been for dependable use and long life. If something should go wrong, the following guide will help you get the pump back into service as quickly as possible. 1. Failure To Start VACUUM PUMP Check the line voltage. The pump ends to start at±10% line voltage (loaded) at 32F. At extremes, switching between the start and run windings may occur. 2. 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. 3. 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. Yo check the oil level, start the pump with the inlet capped, and Check the oil level in the sight glass. Add oil if necessary.
