WARNING
●
Be sure to comply with local
codes on running the wire
from the indoor unit to the
outdoor unit (size of wire and
wiring method, etc.).
●
Each wire must be firmly
connected.
●
No wire should be allowed to
touch refrigerant tubing, the
compressor, or any moving
part.
CAUTION
Be sure to connect the power
supply line to the outdoor unit
as shown in the wiring dia-

To avoid the risk of electric
shock, each air conditioner
unit must be grounded.
