Piping Length/Additional Refrigerant Volume
12.7
The amount of refrigerant put into the Outdoor Unit at the factory is sufficient to fill up to 20m of
!
refrigerant pipework.
If the length of the refrigerant pipework is 20m or less, addition of refrigerant at the installation site
!
is unnecessary.
If the length of the pipework exceeds 20m, extra refrigerant must be added. Refer to the table
!
below for details of the extra amounts.
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 below:
