• Procedure

(1)Confirm that both the 2-way and 3-way valves are set to the back seat.

(2)Connect the charge set to the 3-way valve’s port.

–Leave the valve on the charge set closed.

–Connect the charge hose with the push pin to the service port.

(3)Open the valve (Lo side) on the charge set and discharge the refrigerant until the gauge indicates 0 kg/cm2G.

–If there is no air in the refrigerant cycle (the pressure when the air conditioner is not running is higher than 1 kg/cm2G), discharge the refrigerant until the gauge indicates 0.5 to 1 kg/cm2G. if this is the case, it will not be necessary to apply a evacuatin.

–Discharge the refrigerant gradually; if it is discharged too suddenly, the refrigeration oil will also be discharged.
