NOISE LEVEL
Note : Noise was measured in accordance with JIS standards, Japan.
Between 5 m and 10 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 5 m is charged in the outdoor unit at the factory.
When the piping is longer than 5 m, additional charging is necessary.
For the additional amount, see the table below.
PIPE LENGTH 5 m 10 m 15 m
ADDITIONAL REFRIGERANT None 100 g 200 g
