Notes:
1. SymboIs used in wiring diagram above are,
2. Indoor and outdoor connecting wires have poIarities, make sure to match terminal numbers (S1, S2, S3) for correct wirings.
3. Since the outdoor side electric wiring may change, be sure to check the outdoor unit electric wiring diagram for servicing.
4. This diagram shows the wiring of indoor and outdoor connecting wires (specification of 230V), adopting superimposed system of
power and signal.
w1: When work to supply power separately to indoor and outdoor units was applied, refer to Fig 1.
w2: For power supply system of this unit, refer to the caution label located near this diagram.
