Specifications

▶ Indoor unit power is supplied from the outdoor unit.
▶ On M-Series models, use AWG-14-3 600 VAC-rated
copper wiring between outdoor unit and indoor unit for
high voltage and controls circuits.
▶ On P-Series models, use AWG-16-3 600 VAC-rated
copper wiring between outdoor unit and indoor unit for
high voltage and controls circuits.
▶ If larger gauge wiring is required by code – use that on
S1 and S2 terminals while using proper wire size on S3
communication terminal (16 gauge on P-Series and 14
gauge on M-Series).
▶ Two types of connection patterns, for 1:1 system and for
P-Series “twin" operation (“twinning") are shown in the
diagrams at right.
