▪ Check for leaks again.
▪ Perform vacuum drying again.
NOTICE
Be sure to open the gas stop valve after piping installation
and vacuuming. Running the system with the valve closed,
the compressor may break down.

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 0.1 kg)
INFORMATION
Piping length is the one way length of liquid piping.
4.5.2

To charge 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
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes
CO -equivalent) is used to determine the maintenance
2
intervals. Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
2 Fix the label on the inside of the outdoor unit near the gas and
liquid stop valves.
