Notes:
1.SymboIs used in wiring diagram above are, 
: Connector, 
: Terminal (block).
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.
+1 : Use copper supply wires.
