(Gas leakage)
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 0.5
to 1 kg/cm
2
G (0.05 to 0.1 MPa) .
• If there is no air in the refrigeration cycle [ the pressure
when the air conditioner is not running is higher than 1
kg/cm
2
G (0.1 MPa) ], discharge the refrigerant until the
gauge indicates 0.5 to 1 kg/cm
2
G (0.05 to 0.1 MPa). If
this is the case, it will not be necessary to apply a
evacuation.
• Discharge the refrigerant gradually; if it is discharged
too suddenly, the refrigeration oil will be discharged.
