INFORMATION
Also read the precautions and requirements in the following chapters:
▪
General safety precautions
▪
Preparation
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.
CAUTION
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).
1 Connect the refrigerant cylinder to the service port.
2 Charge the additional refrigerant amount.
3 Open the gas stop valve.
If pump down is needed in case of dismantling or relocating the system, see

"14.2 To pump
down" [
1 Fill in the label as follows:
Do NOT add additional refrigerant.
R=(total length (m) of liquid piping – 1 0 m)×0.020
R=Additional charge (kg) (rounded in units of
0.01 kg)
