4. Installing the refrigerant piping
4.6. Addition of refrigerant
• Additional charging is not necessary if the pipe length does not exceed 21 m, 70 ft
for A12-A30, 30 m 100 ft for A36, A42.
• Especially, additional charging is not necessary if the pipe length does not exceed
30 m 100 ft for A24, 30, 36, A42 connected to the A-COIL indoor unit (PAA-A18,
24, 30, 36, 42).
• 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.

*1. If outdoor unit is connected to the A-COIL indoor unit (PAA-A18, 24, 30, 36, 42), pipe length is "Max. 30 m, 100 ft".
*2. This additional refrigerant chart is used only when connected to an indoor unit other than A-COIL indoor unit (PAA-A18, 24, 30, 36, 42). Additional charging is not necessary
if the pipe length does not exceed 30 m 100 ft for A24, 30, 36, A42 connected to the A-COIL indoor unit (PAA-A18, 24, 30, 36, 42).

Notes:
1. 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 vacu-
umized.
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.
2. 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.
• 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 per-
formance.
