9-1-4. ADDITION OF REFRIGERANT
• Additional charging is not necessary if the pipe length does not exceed 20 m(70 ft) for A12-A36 or 30 m(100 ft) for A42.
• If the pipe length exceeds the specified length above, charge the unit with additional R410A refrigerant according to the
permitted pipe lengths in the chart below.
*
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).
• Be careful when installing multiple units. Connecting to an incorrect indoor unit can lead to abnormally high pressure and have
a serious effect on operation perform
ance.
