Follow local codes for wiring
and safety devices between
outdoor unit and power source.
Recommend using AWG14, stranded and
insulated wire for connections between indoor and
outdoor units.
Local code always supersedes recommendation.
NOTE
Take care to ensure that all wiring between indoor unit and outdoor unit has a consistent connection. Any splices can cause
communication errors.
