• 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 performance.

The air coverage range is the distance to which the 0.8 ft/sec. air can reach, when air is blown out horizontally from the unit at 
the High notch position.
The coverage range should be used only as a general guideline since it varies according to the size of the room and the furni-
ture inside the room.
