[NOTES]
1. Symbols used in wiring diagram above are,
: Terminal (block), : Connector.
2. Indoor and outdoor connecting wires are made with
polarities, 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.
*
When work to supply power separately to Indoor and
Outdoor unit was applied, refer to Fig. 1.
For power supply system of this unit, refer to the caution
label located near this diagram.
