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.
•
Conne ct thechargehosewith thepush 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
gaugeindicates 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.
