Note On Adding Refrigerant

CAUTION
・ Refrigerant charging must be performed after wiring, vacuuming, and the leak testing.
・ 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.
・ Refrigerant containers must be opened slowly. Always use protective gear when charging the system.
・ DO NOT mix refrigerants types.
・ 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.
・ The maximum refrigerant charge amount of R32 is 305 grams.
N=2(1 x 2 models), N=3(1 x 3 models), N=4(1 x 4 models), N=5(1 x 5 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:
