VACUUMING AND CHARGING
Vacuuming is necessary to eliminate all moisture and air from the system.
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 leakage 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.
