INFORMATION
Also read the precautions and requirements in the following chapters:
▪
"2 General safety
▪
"7.1 Preparing refrigerant
If the total liquid piping
length is...
≤10 m
>10 m
If the total liquid piping
length is...
≤10 m
>10 m
INFORMATION
Piping length is the one-way length of liquid piping.
INFORMATION
If a complete recharge is necessary, the total refrigerant charge is: the factory
refrigerant charge (see unit name plate) + the determined additional amount.
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.
