NOTE ON ADDING REFRIGERANT
CAUTION
36
•
• DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system. Doing so
can damage the unit or impact it’s functioning.
• Charging with unsuitable substances may cause explosions or accidents. Ensure that the appropriate
refrigerant is used.
• For the R290 or R32 refrigerant model, make sure the condtions within the area have been made
safe by control of flammable material when the refrigerant added into air conditioner.
Refrigerant containers must be opened slowly. Always use protective gear when charging the system.
•
• DO NOT mix refrigerants types.
N=2(one-twin models), N=3(one-three models), N=4(one-four models), N=5(one-five models).
Depending on the length of connective piping or the pressure of the evacuated system, you made need
to add refrigerant. Refer to table below for refrigerant amounts to be added:
Refrigerant charging must be performed after wiring, vacuuming, and the leak testing.

N=2(one-twin models),N=3(one-three models),N=4(one-four models),N=5(one-five models). Some systems
require additional charging depending on pipe lengths. The standard pipe length is 10m. The additional
refrigerant to be charged can be calculated using the following formula:
Make sure to remove the additional refrigerant charge according to the rated volume (5m refrigerant
piping) when doing market or government verification test.
