VACUUMING AND 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.
