(Lack of refrigerant in the refrigeration cycle)
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 refrigerant
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/cm2G), discharge the refrigerant until the
gauge indicates 0.05 MPa (0.5 km/cm2G) to 0.1 MPa (1
kg/cm2G). 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
discharged.
5. Turn on refrigerant reclaiming equipment.
