Replenishing refrigerant
This model is a 20 m chargeless type that does not
need to have its refrigerant replenished for refrigerant
pipes up to 20 m. When a refrigerant pipe longer than
20 m is used, add the specified amount of refrigerant.
Refrigerant replenishing procedure
1. After vacuuming the refrigerant pipe, close the
valves and then charge the refrigerant while the air
conditioner is not working.
2. When the refrigerant cannot be charged to the
specified amount, charge the required amount of
refrigerant from the charge port of the valve on the
gas side during cooling.
Requirement for replenishing refrigerant
Replenish liquid refrigerant.
When gaseous refrigerant is replenished, the
refrigerant composition varies, which disables normal
operation.
Adding additional refrigerant
21~30 m: L
SM56 20 g × (L-20)
SM80 40 g × (L-20)

The refrigerant need not be reduced for a 20 meter
(or less) refrigerant pipe.
