NOTES:
1.Symbols used in wiring diagram above are,
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 dlagram shows the wiring of Indoor and Outdoor connecting wires
(specification of 230V), adopting superimposed system of power and signal.
