DO NOT START PUMP BEFORE ADDING OIL
The following procedures will prevent oil from being drawn
START-UP
Open one intake port and isolation valve,
close gas ballast valve and start pump.
Make vacuum connections.

may have to be changed several times
during evacuation.
After initial fill up of oil, it is best to check
oil level with pump running.
SHUT-DOWN
Close isolation valve and open gas
ballast valve all the way. Continue
running pump for 2-3 seconds. With
gas ballast valve still opened, stop pump
and then close valve.
Remove hose connections and cap

CHANGING OIL
To reach deep vacuum, Platinum pumps need
clean, moisture-free oil throughout evacuation.
Care should be taken to avoid contact on skin and clothing when changing oil.
Used oil should be disposed of in a leakproof corrosive-resistant container.
1. After every evacuation while pump is warm and oil is thin, place
pump on level surface and open oil drain. Oil can be forced from
the pump by opening one intake 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.
2. Close drain. Remove oil fill cap and fill to top of OIL LEVEL line

TROUBLESHOOTING CHART
Symptom
Pump won’t start.
Pump won’t pull deep vacuum.
Oil drips from point where shaft
enters the pump housing.
Pump shuts down and will not start.
Possible Cause(s)
1. Power cord not plugged in securely.
2. Motor switch not on.
3. Pump temp. below 30°F.
4. Inconsistent line voltage.
1. Contaminated oil.
2. Oil level too low.
3. Air leak in system being evacuated.
4. Pump inlet fittings missing or not
tightened.
5. Coupler slipping
Damaged oil seal.
Thermal overload may be open.
Corrective Action
1. Plug power cord in securely.
2. Turn motor switch to ON position.
3. Warm up pump to 30°F & turn motor
switch on.
4. Line voltage must be within 10% of
115 volt.
1. Change oil.
2. Add oil.
3. Locate & repair leaks.
4. Clean or replace O-ring.
5. Tighten coupler setscrews to flats of
cartridge and motor.
Replace.
Disconnect pump from system. Wait about
15 minutes for motor to cool and turn it on
again. If it cycles off again, return pump to
factory for repair.
Pump cycles on and off from a
completely cold start and then runs
smoothly.
Oil backed up into cartridge and was
being cleared out. Pump has not been
shutdown properly.
1. Remove 1/4" cap.
2. Turn pump on.
