DIAGRAM FOR “PUSH/PULL” METHOD
SET-UP DIAGRAM FOR TANK
PRE OR SUB COOLING PROCEDURE
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 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.
ƽ
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 overfill-
ing of the recovery tank.
See page 10 of this manual for more information.
1. To start you must have a minimum of 5 lbs. of liquid
refrigerant in the tank.
2. Throttle the output valve so that the output pres-
sure is 100 psi greater than the input pressure,
but never more than 300psi.
3. Run until the tank is cold.
