Vacuum Pump Operation; Routine Maintenance - CPS Pro-Set VP2 Operation Manual

VACUUM PUMP OPERATION

WARNING: Do not operate on systems under pressure.
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 IEC inlet to power supply outlet.
4. Check oil level in vacuum pump
5. Connect vacuum pump as shown in Diagram.
6. Open isolation valve (VP4, VP6 only)
and/or manifold valves.
7. Turn vacuum pump power switch "ON".
8. Run vacuum pump until final vacuum
level is met.
9. If the vacuum pump is slow on reaching the
final vacuum level, open the gas Ballas valve
for 1 minute. This will purge moisture that
may have accumulated in the reservoir. Close
Gas Ballast valve.
10. Once the final vacuum level is reached, close
the isolation & manifold valves.
Turn power switch "OFF".
VACUUM OPERATION COMPLETE
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 oil fill cap and add oil until it is seen in the middle of the oil
sight glass. Re-secure oil fill cap.
Damage to the pump may occur.
