Adding refrigerant (R-410A)

The outdoor unit is loaded with sufficient refrigerant for standard piping. Thus, refrigerant must be added if the piping is 

lengthened. This operation can only be performed by a qualified 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 :

2)  Operate the air conditioner by pressing the K2 key on the outdoor unit PCB.
