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 R32 refrigerant model, make sure the conditions 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.
Some systems require additional charging depending on pipe lengths. The standard pipe length
varies according to local regulations. For example, in North America, the standard pipe length is
