Notes:
1.Symbols used in wiring diagram above are, :Connector, :Terminal (block).
2.Indoor and outdoor connecting wires have polarities, 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
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 wires.
Utilisez des fils d’alimentation en cuivre.
