CAUTION
G 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.
G Do not run wiring for antenna, signal, or power lines of television, radio, stereo, telephone,
security system, or intercom any closer than 3'4" (1 m) from the power cable and wires
between the indoor and outdoor units. Electrical noise may affect the operation.
G To avoid the risk of electric shock, each air conditioner
unit must be grounded.
G For the installation of a grounding device, please
observe local electrical codes.
G Grounding is necessary, especially for units using
inverter circuits, in order to release charged electricity
and electrical noise caused by high tension.
Otherwise, electrical shock may occur.
G Place a dedicated ground more than 7' (2 m) away from
other grounds and do not have it shared with other elec-
tric appliances.
