The outdoor unit is loaded with sufficient refrigerant for the standard piping. Thus, refrigerant must be added if the
piping is lengthened. This operation can only be performed by a qualified refrigeration specialist. For quantity of adding
refrigerant, refer to page 17.
1. Check that the stop valve is closed entirely.
2. Charge the refrigerant through the service port of liquid stop valve.
3. If you cannot charge the refrigerant according to the upper steps, 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.

Adding refrigerant
(R-410A)
• Inform user if system contains 5 tCO2e or more of fluorinated greenhouse gases. In this case, it has to be checked for leakage
at least once every 12 months,according to regulation n°517/2014. This activity has to be covered by qualified personnel only.
In case situation above (5 tCO2e or more of R-410A), installer (or recognized person which has responsibility for final check) has to
provide a maintenance book, with all the information recorded according to REGULATION (EU) No 517/2014 OF THE EUROPEAN
PARLIAMENT AND OF THE COUNCIL of 16 April 2014 on fluorinated greenhouse gases.
