9-2-3. CAPACITY CORRECTION
Cooling and heating capacity is lowered according to pipe length. Capacity can be obtained by referring to the capacity
curves below.
Corrected pipe length (m) = actual pipe length (m) + number of bends x 0.3 (m)
Corrected pipe length (ft) = actual pipe length (ft) + number of bends x 1 (ft)

Note: The permitted pipe length is up to 75m<245ft>.

When HAs pipe is one size larger than standard size, capacity can be obtained by referring to capacity curves of
standard size.
9-2-4. ADDITION OF REFRIGERANT
• Additional charging is not necessary if the pipe length does not exceed 30 m (100 ft).
• 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.
