CAUTION

R407C must be charged as liquid. Usually R407C cylinder is equipped with a dip-pipe for liquid withdrawal. If there 
is no dip-pipe, the cylinder should be inverted so as to withdraw liquid R407C from the valve.
Do not top-up when servicing leak, as this will reduce the unit performance. Vacuum the unit thoroughly and then 
charge the unit with fresh R407C according to the amount recommended in the speci

fi

 cation.

PURGE BY CHARGING

Vacuuming is necessary to eliminate all moisture and air from the system. The series II Outdoor Unit is provided with flare 
valve fittings.

Vacuuming The Piping And The Indoor Unit

Except for the outdoor unit which is pre-charged with 
refrigerant, the indoor unit and the refrigerant connection 
pipes must be air-purged because the air containing moisture 
that remains in the refrigerant cycle may cause malfunction 
of the compressor.

Remove the caps from the valve and the service port.
 Connect the center of the charging gauge to the vacuum 
pump.
 Connect the charging gauge to the service port of the 3-way 
valve.
 Start the vacuum pump. Evacuate for approximately 30 
minutes. The evacuation time varies with different vacuum 
pump capacity. Confirm that the charging gauge needle has 
moved towards -760mmHg.

Caution

 If the gauge needle does not move to -760mmHg, be sure to 
check for gas leaks (using the refrigerant detector) at flare 
type connection of the indoor and outdoor unit and repair 
the leak before proceeding to the next step.
 Close the valve of the changing gauge and stop the vacuum 
pump.
 On the outdoor unit, open the suction valve (3 way) and 
liquid valve (2 way) (in anti-clockwise direction) with 4mm 
key for hexagon sacked screw.

Charge Operation

This operation must be done by using a gas cylinder and a 
precise weighing machine. The additional charge is topped-up 
into the outdoor unit using the suction valve via the service 
port.

Remove the service port cap.
 Connect the low pressure side of the charging gauge to the 
suction service port center of the cylinder tank and close 
the high pressure side of the gauge. Purge the air from the 
service hose.
Start the air conditioner unit.
Open the gas cylinder and low pressure charging valve.
 When the required refrigerant quantity is pumped into 
the unit, close the low pressure side and the gas cylinder 
valve.
 Disconnect the service hose from service port. Put back 
the service port cap.
