OPERATION MANUAL

GENERAL INFORMATION

Introduction

Thank you for purchasing the CPS® Pro-Set® VP vacuum pump series. Our vacuum pumps are specifically designed for the air-conditioning and refrigeration service industry. The VP and VPC series both utilize an electrical motor and oil filled rotary vacuum pump cartridge construction.

Features:

• Equipped with our exclusive oil mist free exhaust port
• VP series dual stage models are equipped with gas ballast valve
• The dual voltage models can be quickly converted to 115 or 230 volt operation
• Sure-Grip handle, ergonomically designed for superior comfort and portability
• Solid rubber base provides extreme shock resistance
• Air cooled motor design allows for operation under high temperature conditions
• The VP & VPC series excel in vacuum performance, rated 10-15 microns (Dual Stage) and 50-100 microns (Single Stage)
• All vacuum pumps allow for multiple connections, therefore giving full operational preference
• Accessible oil drain port & sight glass make both oil maintenance and accuracy easy

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.

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.

Troubleshooting Chart

Condition	Possible Problem	Solution
Unusually noisy	1. Bad bearings. 2. Loose motor bolts. 3. Coupling drive. 4. Dirty, low, or improper oil. 5. Air leaks in connections.	1. Replace motor. 2. Tighten bolts. 3. Adjust or replace coupling. 4. Replace oil. 5. Fix leaks.
High temperature	1. Low or improper voltage. 2. Worn bearings. 3. Low oil level.	1. Check power source voltage. 2. Replace motor. 3. Add or replace.
Poor vacuum	1. System leaks. 2. Low oil level. 3. Dirty oil. 4. Air leaks at connection. 5. Air leak through seal. 6. Worn rotary mechanism.	1. Fix leaks. 2. Add or replace oil. 3. Flush and replace oil. 4. Fix leaks. 5. Replace shaft seal. 6. Replace cartridge.
Oil leaks	1. Oil leaks through exhaust. 2. Oil leaks through shaft seal. 3. Oil leaks through reservoir. 4. System vented pressure. 5. Pump tipped over.	1. Oil level too high. 2. Replace shaft seal. 3. Tighten bolts or replace gasket. 4. Check oil level. 5. Check oil level.
Pump does not start	1. No power to motor. 2. Damaged motor. 3. Thermal cutout.	1. Check fuses in IEC panel. 2. Replace motor. 3. Wait for thermal switch to reset. Check for cause of thermal.
Thermal cutout	1. Low or incorrect voltage. 2. Cold weather. 3. Dirty Oil.	1. Check voltage, move voltage selector switch to correct setting. 2. Start and run vacuum pump with the intake fitting open for 1 minute to warm up oil. 3. Flush and replace oil.
