Specifications

Push/pull method only works with large systems where the liquid is readily accessible. Do not use this
method on systems that contain less than 6.8 kg (15 lbs.) as it may not work.
The sight glass is used to provide a method of determining the moisture content and quality of a system’s
refrigerant.
m CAUTION: When using the “Push/Pull” method, once the siphon is started, it can continue and overfill
the storage tank even if the tank is equipped with a float level sensor. The siphon can continue even
when the machine is turned off. You must manually close the valves on the tank and the unit to prevent
overfilling of the recovery tank.

PRE OR SUB COOLING PROCEDURE
See page 9 for more information on Sub Cooling.
Note: To begin this process you must have a minimum
of 5 lbs. of liquid refrigerant in the tank. If this is not the
case, using a fully evacuated empty tank will help you
achieve the fastest recovery time.
1. Close INPUT and OUTPUT valves
2. Turn MODE knob to "RECOVERY"
3. Turn RECOVERY/PURGE knob to "RECOVER"
4. Start machine
5. Open INPUT valve to the "LIQUID" position
6. Throttle the OUTPUT valve so that the output pres-
sure is 100 psi greater than the input pressure, but
never more than 300 psi
7. Run until tank is cold
1. Close INPUT and OUTPUT valves
2. Turn MODE knob to "RECOVERY"
3. Turn RECOVERY/PURGE knob to "RECOVER"
4. Start machine
5. Open INPUT valve to the "VAPOR" position and
OUTPUT valve to "OPEN"
6. When the refrigerant scale stops rising, close all
ports
CAUTION: Do not overfill tank
7. Turn MODE knob to "STOP"
8. Switch off machine
