ADDITIONAL CHARGE OF REFRIGERANT

(ASY9FSBCW / AOY9FSBC)

(ASY12FSBCW / AOY12FSBC)

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

ADDITIONAL REFRIGERANT None 50 g

15 m

150 g

Between 7.5 m and 10 m, when using a connection pipe other than that in the table,

charge additional refrigerant with 20g /1 m as the criteria.

(The maximum length of piping is 15m. If the units are further apart than this, correct

operation can not be guaranteed.)
