2. Additional Charge
The refrigerant is pre-charged in the outdoor unit. If the piping length is less than 5m, additional charge after vacuuming is not
necessary. When the piping length is more than 5m, use the table below.

1. Purging 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
airpurged because the air containing moisture that remains in the
refrigerant cycle may cause malfunction of the compressor.
The outdoor unit is equipped by two 3 ways refrigerating
connecting valves. The suction valve is the larger one while the
small one is the liquid valve. Both valves are supplied with service
port valve for connection to a manometer.
• 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. Check the low pressure manifold gauge
until it indicates 0.9 bar. The evacuation time varies with each
vacuum pump capacity but generally in half an hour.
• Close the manifold valve and stop the vacuum pump.
• On the outdoor unit, open the suction and liquid valve (anti
clockwise) with 4mm key for hexagon sacked screw.
• The air conditioner unit is ready for start.
• If the reading is close to 0, the refrigerant circuit must be
evacuated (by vacuum pump) and charged again.

Check with refrigerant detector whether there is a
leak on the flare type connection of the indoor unit
and outdoor unit.
