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 com-
pressor, or any moving part.
Be sure to connect power wires correctly matching up numbers on
terminals of the outdoor unit and respective indoor units A – D.
To avoid the risk of electric shock, each air conditioner unit must
be grounded.
Be sure to connect the power supply line to the outdoor unit as
shown in the wiring diagram. The indoor unit draws its power from
the outdoor unit.
