The high side pressure gauge must be capable of
reading pressures up to 800 psi.
NOTE
: Using the recovery pump, achieve a 15-
Inch vacuum prior to charging the system.
After Recovery Is Complete
1. Set up recovery pump, recovery tank, gauge
manifold, and scale (see
Refrigerant
Charging Connections
).
2. Connect the blue hose from the refrigerant
cylinder to the low side port of the manifold.
3. Open the R-410A refrigerant cylinder to purge
the air from the blue refrigerant hose using
the low side port manifold valve.
4. Connect the yellow hose from manifold to the
charge valve on the high-pressure side of the
sealed system.
5. Connect the red hose from the manifold
gauge to the filter on the inlet port of the
recovery pump.
6. Connect the outlet port of the recovery pump
