Oil change Procedure
➢ Be sure the pump is warmed up.
➢ Remove the OIL DRAIN cap. Drain contamined oil into a suitable
container and dispos 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.
➢ When the flow of oil has stopped, tilt the pump forward to drain
residual oil.
➢ 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 220-250 mL.
➢ Be sure the inlet ports are capped, then turn on the pump. Allow it
to run for one minute, then check the oil level. If the oil is below the
sight glass OIL LEVEL line. Replace the OIL FILL cap, making sure
the inlet is capped and the drain cap is tight.
➢ If the oil is badly contamined 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.
➢ Another method of dealing with heavily contamined 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 force 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.
6 Troubleshooting Guide
Your pump has been designed for dependable use and long life. If
something should go wrong, however, the following guide will help you
get 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.
6.1
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.
6.2
Oil leakage
➢ Be sure the oil is not a residual accumulation from spillage, etc.
➢ If leakage exists, the module covers 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.
