•
The amount of refrigerant put into the outdoor unit at the factory is equivalent to the one that fills up 20m length of
refrigerant pipe.
•
If the length of refrigerant pipe is 20m or less, addition of refrigerant at the installation site is unnecessary. If the length of
the pipe exceeds 20m, add the refrigerant R-22.
•
Overcharge or undercharge of refrigerant in the outdoor unit will cause malfunction of the compressor. The prescribed
amount of the replenishment of the refrigerant is shown in the table above.
The permissible amount of refrigerant is the prescribed 50g.
•
For RAV-362A8-PE and RAV-462A8-PE, if the length of pipe exceeds 30m the diameter of the gas pipe must be increased
by one rank (i.e. 19.0
→
22.2).
