Before Operation
When you keep on tightening the flare nut with a spanner, there is a point where the tightening torque
suddenly increases. From that position, further tighten the flare nut the angle shown below:
Pipe size
6.4 (1/4")
9.5 (3/8")
12.7 (1/2")
15.9 (5/8")
19.1 (3/4")
8.2.5 Misswiring Check Operation
(Refer to the "CAUTION ON OPERATION" on the PCB (A1P) on the outdoor unit for settings. Operation
will not be possible immediately after power is turned on (until the LED H2P goes off: up to 12 minutes).
1. Use monitor mode to check the number of indoor units connected.
2. Press the "Wiring check" button for 5 seconds after returning to setting mode 1, and carry out the
miswiring check operation. The LED H2P will light up during operation and go out when complete.
3. After completion of operation, wait about one minute, and then use monitor mode to check the number
of indoor units connected again to see whether the number is the same as before. If it is not, the
difference represents the number of indoor units whose wiring has been done incorrectly. Use the
operation remote control to operate the indoor units, and correct the wiring on units which display "UF"
on the remote control.
8.2.6 Disposal Requirements
Dismantling of the unit, treatment of the refrigerant, oil and eventual other parts, should be done in
accordance with the relevant local and national regulations.
