Adding refrigerant

i.e. 1 indoor unit 

If you have used more than “P”, add "Q" of refrigerant for extra meter.  
(For maximum piping length and height, refer to page 13)    

 

The quantity of additional refrigerant is variable according to the installation 
situation. Thus, make sure the outdoor unit situation before adding    
refrigerant. This operation can only be performed by a qualified refrigeration  
specialist.
