5. Remove the OiL FiLL CAP (Model 15310 or 15510) or EXHAUST
FittiNg (Model 15115), and fill the reservoir with new vacuum pump
oil until the oil appears at the bottom of the sight glass. For oil capacities,
refer to Pump Specifications in this manual.
6. Verify the inlet ports are capped; then turn ON the pump. allow it to run
for one minute, and 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 OiL LeVeL line. Replace the OiL FiLL CaP / exhaust
FittiNg, and confirm the inlet is capped and the drain cap is tight.
7. a) if the oil is badly contaminated with the sludge that forms when water
is allowed to collect in 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 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 until fresh oil
appears at the bottom of the sight glass.
Clean the pump with soap and water only. Do not use commercial
cleaners that contain degreasing agents.
this product must be grounded. in the event of an electrical short,
grounding reduces the risk of electrical shock by providing an escape
wire for the electric current. This product is equipped with a power cord
having a grounding wire with an appropriate grounding plug. The outlet
used must be correctly installed and grounded according to local codes
and ordinances.
waRNING : Incorrect installation of the grounding plug
will result in electrical shock. when repair or replacement
of the power cord or plug is required, do NOt connect the
grounding wire to either flat blade terminal. The wire with
green insulation (with or without yellow stripes) is the
grounding wire.
