1.SymboIs used in wiring diagram above are, :Connector, :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 208V/230V), adopting superimposed
system of power and signal.
● For power supply system of this unit, refer to the caution label located near this diagram.
1:Use copper supply wire.
