Adding refrigerant (R-410A)
The outdoor unit is loaded with sucient refrigerant for standard piping. Thus, refrigerant must be added if the piping is
lengthened. This operation can only be performed by a qualied refrigeration specialist. For volume of additional refrigerant,
refer to “How to Calculate the Volume of Additional Refrigerant” section.
1. Check that the stop valve is closed entirely.
2. Charge the refrigerant through the service port of liquid stop valve.
• Do not charge the refrigerant through the gas side service port.
NOTE
3. If you cannot charge the refrigerant according to the steps above, following these :
1) Open both liquid stop valve and gas stop valve.
2) Operate the air conditioner by pressing the K2 key on the outdoor unit PCB.
3) About 30 minutes later, charge the refrigerant through the service port of gas stop valve.
• If necessary, refer to the pressure table classied by outdoor temperature.

How to Calculate the Volume of Additional Refrigerant
The volume of additional refrigerant is variable according to the length of the liquid pipe. Determine the liquid pipe length
before adding refrigerant. This operation can only be performed by a qualied refrigeration specialist.
