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.
