Push Pull Recovery Procedure - Appion G5 Twin Operation Manual

Machine Usage
⚠ CAUTION
To reduce the risk of injury or product damage, read this entire operating manual, with
particular emphasis on the Safety and Preparation sections (Page 3-8), prior to operating the G5Twin.
PUSH/PULL RECOVERY PROCEDURE
The Push/Pull method induces a siphon from the system directly into the recovery cylinder using the G5Twin.
This method is useful for recovering large amounts of liquid from a system. This will only work on large
systems where the liquid can be accessed easily. Do not attempt this on systems that contain less than 15 lbs.
of liquid refrigerant (unless there is a receiver tank), or it may not work correctly.
⚠ CAUTION
Once the siphon starts, it can continue to fill the tank even when the machine has been
powered o . To avoid overfilling, you must close all valves on the tank and system when finished.
1. Setup the G5Twin as shown in Diagram 7 (below). Make sure that all connections are tight.
A. Connect a Valve Core Removal Tool to the AC/R System Liquid Port.
B. Connect a Valve Core Removal Tool to the AC/R System Vaport Port.
C. Connect the AC/R System Vapor Port to the G5Twin output port.
D. Connect the AC/R System Liquid Port to the Recovery Cylinder Liquid port.
E. Connect the G5Twin input port to the Recovery Cylinder Vapor port.
Diagram 7
The Push/Pull recovery method induces
a siphon to move large amounts of liquid
directly from the system to the recovery
cylinder.
2. Slowly open both valves on the G5Twin.
3. Turn on the G5Twin. The compressor and fan should start.
4. Slowly open the valves on the tank and system. The liquid should now begin to be pulled out of the
system. You can monitor the progress with an inline sight glass.
Make sure to completely open the Recovery Cylinder valves to prevent "output restrictions" (SeeTip #1,
Page 14).
5. When all the liquid has been siphoned o , turn o the G5Twin and close all the valves.
6. You can now proceed to remove the remaining refrigerant vapor using the Standard Recovery Procedure
(Page 9).
