• 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

CAUTION: DO NOT RUN THIS EQUIPMENT WITH LOW OR NO OIL. RUNNING
THIS EQUIPMENT WITH NO LUBRICATION WILL CAUSE PREMATURE FAILURE.
DANGER - Avoid breathing refrigerant
vapors and lubricant vapor or mist. Breath-
ing high concentration levels may cause
heart arrhythmia, loss of consciousness,
or even cause suffocation.
DANGER - ELECTRICAL SHOCK
HAZARD - Always disconnect power
source when servicing this equipment.
WARNING - Do not operate the vacuum
pump on systems under pressure. Dam-
age to the pump may occur.
CAUTION - All hoses may contain liquid
refrigerant under pressure. Contact with
refrigerant may cause frostbite or other
related injuries. Wear proper personal pro-
tective equipment such as safety goggles
and gloves. When disconnecting any hose,
please use extreme caution.
CAUTION - Avoid breathing refriger-
ant vapors and/lubricant mist. Exposure
may irritate eyes, nose, throat and skin.
Please read the manufacturers Mate-
rial Safety Data Sheet for further safety
information on refrigerants and lubricants.
CAUTION - To reduce the risk of fire, avoid
the use of extension cords thinner than
NO. 14 awg. (2,5mm2) to prevent the over-

Vacuum Pump Operation
Initial Preparation
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.
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.

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.
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”.
