If the total liquid piping
length is…
Then…
≤10m Do NOT add additional refrigerant.
>10m R=(total length (m) of liquid piping⁠–⁠10m)×0.020
R=Additional charge (kg) (rounded in units of
0.01kg)
INFORMATION
Piping length is the one-way length of liquid piping.
8.4.4 To determine the complete recharge amount
INFORMATION
If a complete recharge is necessary, the total refrigerant charge is: the factory
refrigerant charge (see unit name plate) + the determined additional amount.
8.4.5 To charge additional refrigerant
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).
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
"15.2To pump down"[4267] for more details.
