NOTICE
Before completely recharging, perform vacuum drying on the outdoor unit's internal
refrigerant piping as well.
Typical workflow – Completely recharging refrigerant typically consists of the
following stages:
1 Determining how much refrigerant to charge.
2 Charging refrigerant.
3 Filling in the fluorinated greenhouse gases label, and fixing it to the inside of
the outdoor unit.
INFORMATION
Also read the precautions and requirements in the following chapters:
▪
"3 General safety
▪
"8.1 Preparing refrigerant
If the total liquid piping
length is...
≤10 m
>10 m
INFORMATION
Piping length is the one-way length of liquid piping.
WARNING
▪
ONLY use R410A as refrigerant. Other substances may cause explosions and
accidents.
▪
R410A contains fluorinated greenhouse gases. Its global warming potential (GWP)
value is 2087.5. 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).
