IV. Troubleshooting Guide
Following guide will help you to recover the functionality should there be any
malfunction occurs:
1. Failure To Start
Check the operating voltage. The pumps are designed to start at ±10% operating
voltage (loaded) at 5°C. However, if exceeded the maximum voltage, switch
malfunction may occur.
2. Oil leakage
(a) Ensure the oil is not a spillage from vacuum pump, etc.
(b) If leakage exists, the housing gasket or the shaft seal may need to be replaced. 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 Attain A Good Vacuum
(a) Ensure 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.
(b) Ensure the pump oil is clean. A badly contaminated pump may require several oil
flushes.
(c) Ensure the oil is at the proper level. For optimum pump operation, the oil must be
even with the Oil Level line on the sight glass when the pump is running. Do not
overfill as operating temperatures will cause the oil to expand, which will appear at a
higher level than when the pump is not running. To check the oil level, start the pump
with the inlet covered. Check the oil level in the sight glass. Add oil if necessary.
