Procedure for Fast Recovery Procedure for Fast Recovery Procedure for Fast Recovery Procedure for Fast Recovery
The goal of any technician is to recover all the refrigerant from an A/C system in as short a time as possible.
This refrigerant will typically be in both liquid and vapor states. The TX200 must never be connected directly
to a source of liquid refrigerant, as this may damage the unit. The following shows Cylinder 1 connected
between the A/C system and the TX200. Scale 3 should be used to prevent overfilling Cylinder 1. The Liquid
in the A/C system will be rapidly drawn into Cylinder 1 as the TX200 recovers vapor only and stores it in
Cylinder 4. The liquid can be observed in Sight Glass 2 connected in-line.
When all the liquid is removed, Cylinder 1 should be removed and the TX200 connected directly as shown in
the next illustration. The TX200 will then rapidly draw all the remaining vapor refrigerant from the A/C system.
Once the A/C system has been emptied, the TX200 can be reconnected to Cylinder 1 and the remaining
refrigerant recovered (this can be done while the technician is servicing the A/C system).
