Note : Noise was measured in accordance with JIS standards, Japan.
Between 7.5 m and 15 m, when using a connection pipe other than that in the table,
charge additional refrigerant with 20 g /1 m as the criteria.
ADDITIONAL REFRIGERANT CHARGE
Refrigerant suitable for a piping length of 7.5 m is charged in the outdoor unit at the factory.
When the piping is longer than 7.5 m, additional charging is necessary.
For the additional amount, see the table below.
PIPE LENGTH 7.5 m 10 m 15 m
ADDITIONAL REFRIGERANT None 50 g 150 g
The maximum length of the piping is 15 m. If the units are further apart than this,
correct operation can not be guaranteed.
