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) Connect the charge set’s centre hose to refriger-
ant reclaiming equipment.
● Purge the air from charge hose.
(4) Open the valve (Low side) on the charge set
and discharge the refrigerant until the gauge
indicates 0.05 MPa (0.5 kg/cm
2
G) to 0.1 MPa
(1 kg/cm
2
G).
● If there is no air in the refrigeration cycle (the pressure
when the air conditioner is not running is higher than
0.1 MPa (1 kg/cm
2
G), discharge the refrigerant until
the gauge indicates 0.05 MPa (0.5 kg/cm
2
G) to 0.1
MPa (1 kg/cm
2
G). 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 also be dis-
charged.
(5) Turn on refrigerant reclaiming equipment .
