INTRODUCTION
Your vacuum pump has been factory tested and meets Robinair’s stringent
quality standards. This high performance pump will provide you with years of
trouble-free service if you follow these instructions for operating and maintain-
ing the pump.
The pump’s offset rotary vane design provides high efficiency operation. The
motor is properly sized to ensure 32
o F (0 o C) starting at 90 percent of the rated
voltage. And the inlet “tee” fitting lets you use one pump for R-12, R-22,
R-500, R-502, and R-134a systems.
Be careful when removing the pump and contents from the shipping carton. If
there is any apparent shipping damage to the pump, the shipping company
should be notified immediately and the container saved for inspection.
OPERATING INSTRUCTIONS
WARNING! Wear safety goggles when working with
refrigerants. Contact with refrigerant can cause eye
injury.
1. Remove and discard the red shipping plug at the top of the finned reservoir.
2. Fill the pump reservoir to the “OIL LEVEL” line on the sight glass on the
front of the pump. Use the oil packaged with the vacuum pump or fresh
Robinair Premium High Vacuum Pump Oil, available at your supplier.
3. Install the black plastic operating exhaust plug. Note that the operating plug
is notched to allow exhaust flow.
CAUTION! Do not attempt to operate the pump with the exhaust
port plugged. To do so could result in permanent damage to the
pump or could cause the plug to be blown from the pump reservoir.
4. Note the electric motor voltage rating, and connect to the proper power
source.
CAUTION! Avoid the use of extension cords. An exten-
sion cord may overheat and cause fire. If you must use an
extension cord, use the shortest possible cord with a
minimum size of 14 AWG.
You are now ready to remove the inlet cap for the appropriate inlet ( 1 /

" for
R-12, R-22, R-500, and R-502; 1 /

the air conditioning system. Follow the system manufacturer’s directions for
evacuation.

FAILURE TO START
1. Check the line voltage. Your vacuum pump is designed to start at minus
ten percent of rated voltage and at 32 o F (0 o C). However, at or near these
extremes, there may be some hesitation in starting.
2. If the pump is accidentally shut down in a vacuum condition, the pump
may hesitate when restarted. This is because the vacuum pump oil has been
drawn into the pump module. The pump will run normally after clearing
the oil from the module.
Oil Leakage
1. Verify the oil is not a residual accumulation due to spillage, overfilling, or
similar causes.
2. If the pump is actually leaking oil, you may have to replace the O-ring in
the end shell or return the pump to the factory for servicing.
WARRANTY
Robinair high vacuum pumps are warranted against defects in material or work-
manship for a period of one year of normal use from date of purchase. If within
one year from date of purchase, the vacuum pump should prove faulty due to
manufacturer error, return it to the distributor from whom you originally purchased
the vacuum pump. You must provide the distributor with proof of purchase and
the warranty claim check tag which is supplied with each vacuum pump.
Upon determining that a valid warranty claim exists, the Robinair distributor is
authorized to exchange the faulty vacuum pump for a new vacuum pump of the
same model at no additional charge. If a vacuum pump is returned for a warranty
claim and the claim is determined to be invalid, a minimum service charge plus
the cost of repair parts and return freight will be charged. Final determination of
valid warranty claims will be made by Robinair, Owatonna, MN.
The warranty shall not apply to any product or part which has been subject to
