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.
If diassembly 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.
1.Failure To Start
Check the line voltage. The pump ned to start at ±10% line voltage (loaded) at 32°F. At extremes,
switching between the startand 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 OIL LEVEL line on the sight glass when the pump is running. Do not overfill operating
temperatures will cause the oil 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.
(5)Be sure the inlet ports are capped then turn on the pump. Allow it to run for one minute then
check the oil level space. If the oil is below the sight glass OIL LEVEL line add oil slowly (with the
pump running) until the oil reaches the OIL LEVEL line. Replace the exhaust fitting, making sure
the inlet is capped and the drain cap is tight.
(6) a) lf 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 not 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 force the oil from it, carrying more contamination. When the oil ceases to flow,
turn off the pump.
Repeat this procedure as required until the contaminatin is removed.
Replace the OIL DRAIN cap and refill the reservoir to the proper level with fresh pump oil.
