4. Installing the refrigerant piping
4.6. Addition of refrigerant
• Additional charging is not necessary if the pipe length does not exceed 30 m.
• If the pipe length is exceeded, charge the unit with additional R410A refrigerant
according to the permitted pipe lengths in the following table.
* When the unit is stopped, charge the unit with the additional refrigerant
through the liquid stop valve after the pipe extensions and indoor unit have
been vacuumized.
When the unit is operating, add refrigerant to the gas check valve using a
safety charger. Do not add liquid refrigerant directly to the check valve.
* After charging the unit with refrigerant, note the added refrigerant amount on
the service label (attached to the unit).
Refer to the "1.5. Using R410A refrigerant air conditioners" for more informa-
tion.
