Check items
1. Grounding protection with a no-fuse breaker (earth leakage breaker[ELB]) is usually installed for B and K.
2. The power cable thickness of C and B have been selected for a voltage drop up to 20m.If the cable length exceeds
20m,select a cable thickness appropriate to that estimated voltage drop.
3. The connection wiring F between the outdoor and indoor units can be extended up to a maximum of 50 meters,and the
total extension including the crossover wiring between rooms is a maximum of 80m.
Use flat cable (three core wires) for indoor and outdoor connection wiring,and connect the core wires in their line-up order
to S1,S2,and S3 of the outdoor unit’s terminal board.(The core wire connected to terminal S2 should be in the center.)
4. Be careful about choosing the installation location for the earth leakage breaker and how it is installed as the initial electric
current may cause it to malfunction.

Check items
1. The power cable thickness have been selected for a voltage drop up to 20 m. If the cable length exceeds 20 m, select a
cable thickess appropriate to tthat estimated voltage drop.
2. Be careful about choosing the installation location for the earth leakage breaker and how it is installed as the initial electric
current may cause it to maifunction.
3. Power supply cords and indoor unit / Outdoor unit connecting cords shall not be llghter than polychloroprene sheathed flex-
ible cord. (design 254 IEC 57)
..
Caution:
Do not push the contactor button (52C) on the outdoor unit, otherwise the compressor may be damaged.
