Notes: 1. SymboIs used in wiring diagram above are,
:Terminal (block).
2. Indoor and outdoor connecting wires are made with poIarities,
make wiring matching terminal numbers (S1, S2, S3).
3. Since the outdoor side electric wiring may change, be sure to
check the outdoor unit electric wiring for servicing.
4. This diagram shows the wiring of indoor and outdoor connecting
wires.(specification of 230V), adopting superimposed system
of power and signal.
*1: When work to Supply power separately to indoor and
outdoor units was applied, refer to Fig 1.
*2: For power supply system of this unit, refer to the caution
