Sub Cooling The Recovery Tank; Recovery Procedures - Haier GE AZ95H09DACK1 Technical Service Manual

Sub Cooling the Recovery Tank

When working in extreme ambient temperatures,
the recovery tank can be sub cooled before the
recovery procedures are performed. This sub
cooling can speed up the recovery process.
NOTE: To sub cool the recovery tank, it is
necessary for the tank to contain a minimum of
5-pounds of liquid R-410A in the tank.
1. Connect one end of the blue hose to the
pump inlet port and the other end to the vapor
port on the recovery tank.
2. Connect one end of the red hose to the pump
outlet port and the other end to the liquid port
on the recovery tank.
3. Start the recovery pump.
4. Throttle the output valve so that the output
pressure is 100 psi greater than the input
pressure, but not more than 300 psi.
5. Run until the recovery tank is cold.

Recovery Procedures

Standard recovery procedures remain unchanged.
The only difference is the necessity to use a
recovery machine and cylinders approved for the
higher pressures of R-410A.
WARNING: When working in extreme ambient
temperatures, the recovery tank can be sub
cooled before the recovery procedures are
performed (see Sub Cooling the Recovery
Tank, previous section).
NOTE: Check all hoses to make sure the "O"
rings are in place before connecting to system.
1. Tap the sealed system at the process stub
tube, using the WR5X27079 tap valve.
