Note1.Since the outdoor side electric wiring may change be sure
to check the outdoor unit electric wiring for servicing.
2.Indoor and outdoor connecting wires are made with polarities,
make wiring matching terminal numbers (S1,S2,S3).
3.Symbols used in wiring diagram above are as follows.
, :CONNECTOR
:TERMINAL
(HEAVY DOTTED LINE):FIELD WIRING
(THIN DOTTED LINE):OPTIONAL PARTS
SYMBOL EXPLANATION
4.Use copper supply wire.
