Charging refrigerant
4.5.1
To determine the additional refrigerant
amount
If the total liquid
piping length is...
≤10 m
Do NOT add additional refrigerant.
>10 m
R=(total length (m) of liquid
piping – 1 0 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.
4.5.2
To charge additional refrigerant
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.
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.

NOTICE
Applicable legislation on fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO

Formula to calculate the quantity in CO
tonnes: GWP value of the refrigerant × total refrigerant
charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge
label.
2 Fix the label on the inside of the outdoor unit near the gas and
liquid stop valves.
