Initial Preparation

1. If the vacuum pump is equipped with a dual voltage motor, make sure the voltage selector switch is set for the desired voltage operation.
2. The vacuum pump is shipped without oil in the reservoir. Remove the exhaust/oil fill cap and add oil until it is seen in the middle of the oil sight glass. Re-secure cap.
3. Remove the 1/4″ inlet service port cap, turn on the vacuum pump. After 15 seconds, replace 1/4 cap back on inlet port.
4. Re-check vacuum pump oil level. Add or remove oil if necessary.
   To achieve good final vacuum levels, the oil level should be visually seen through sight glass.

CAUTION: DO NOT RUN THIS EQUIPMENT WITH LOW OR NO OIL. RUNNING THIS EQUIPMENT WITH NO LUBRICATION WILL CAUSE PREMATURE FAILURE.

VACUUM PUMP IS NOW READY FOR USE.

Vacuum Pump Operation

WARNING: Do not operate on systems under pressure.

Damage to the pump may occur.

1. Check the correct power supply outlet to be used.

2. The VP series is equipped with a dual voltage motor. Make sure the voltage selector switch is set for the desired voltage operation.
   Caution: The motor will overheat and trip the thermal protector if the voltage selector and the power supply voltage do not match.

3. Connect the correct power cord from vacuum pump to power supply outlet.

4. Check oil level in vacuum pump.

5. Connect vacuum pump as shown in Figure – 1.

6. Open manifold valves.

7. Turn vacuum pump power switch “ ON ”.

8. Run vacuum pump until final vacuum level is met.

9. Once the final vacuum level is reached, close manifold valves, turn power switch “ OFF ”.

VACUUM OPERATION COMPLETE

Routine Maintenance

It is recommended to change the vacuum pump oil after 50 hours of usage. The purity of the oil will determine the final vacuum level achieved. Always use the CPS recommended vacuum pump oil ( VPOQ / VPOP / VPOG ). The oil provided with the pump has been specially blended to maintain maximum visosity at normal running temperatures as well as cold weather starts.

OIL CHANGE PROCEDURES:

1. Be sure the pump oil is warmed up. if not warm, turn vacuum pump “ ON ” for 10 minutes.
2. Make sure vacuum pump is not plugged in.
3. Remove the oil drain cap and drain the contaminated oil into a suitable container. Tilt the vacuum pump toward the oil drain port.
4. Once all the oil has been drained, re-secure the oil drain cap back onto the oil drain port.
5. Remove the exhaust / oil fill cap and add oil until it is seen in the middle of the oil sight glass. Re-secure exhaust/oil fill cap.
