Be sure to use a hexagonal wrench to operate the valve stems.
7. Mount the valve stems nuts and the service port cap.
Be sure to use a torque wrench to tighten the service port cap to a torque 18N.m.
Be sure to check the gas leakage.
6.7 Balance refrigerant of the 2-way, 3-way valves
Procedure:
1. Confirm that both the 2-way and 3-way valves are set to the open position.
2. Connect the charge set to the 3-way valve’s service port.
Leave the valve on the charge set closed.
Connect the charge hose with the push pin to the service port.
3. Open the valves (Low side) on the charge set and discharge the refrigerant until the gauge indicates
0.05 to 0.1Mpa.
If there is no air in the refrigeration cycle the pressure when the air conditioner is not running is higher
than 0.1Mpa, discharge the refrigerant until the gauge indicates 0.05 to 0.1 Mpa. In this case, it will not
be necessary to apply an evacuation.
Discharge the refrigeration gradually; if it is discharged too suddenly, the refrigeration oil will be
discharged.
