6. PERFORMANCE CHARACTERISTICS
Piping Length/Additional Refrigerant Volume
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:
