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 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.
