WARNING
▪ Only use R32 as refrigerant. Other substances may cause explosions and
accidents.
▪ R32 contains fluorinated greenhouse gases. Its global warming potential (GWP)
value is 675. Do NOT vent these gases into the atmosphere.
▪ When charging refrigerant, ALWAYS use protective gloves and safety glasses.
NOTICE
To avoid compressor breakdown, do NOT charge more than the specified amount of
refrigerant.
Prerequisite: Before charging refrigerant, make sure the refrigerant piping is
connected and checked (leak test and vacuum drying).
