2) Balance refrigerant of the 3-way(liquid side), 3-way(gas side) valves
(Gas leakage)
• Procedure
Confirm that both the liquid side and gas side valves are set to the back seat.
Connect the charge set to the 3-way(gas side) valve's port.
• Leave the valve on the charge set closed.
• Connect the charge hose with the push pin to the service port.
Open the valve (Lo side) on the charge set and discharge the refrigerant until the gauge indicates 0 kg/cm
2
g.
- If there is no air in the refrigerant cycle (the pressure when the air conditioner is not running is higher than 1
kg/cm
2
g), discharge the refrigerant until the gauge indicates 0.5 to 1 kg/cm
2
g. In case of this, it will not be nec-
essary to apply an evacuation.
- Discharge the refrigerant gradually; if it is discharged too suddenly, the refrigeration oil will also be discharged.
