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.
WARNING
To avoid the risk of electrical shock, each air
conditioner unit must be grounded.
For the installation of a grounding device, please
observe local electrical codes.
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.
Place a dedicated ground more than 2 meters away
from other grounds and do not have it shared with
other electric appliances.
CAUTION
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.
Do not run wiring for antenna, signal, or power lines of
television, radio, stereo, telephone, security system,
or intercom any closer than 1 meter from the power
cable and wires between the indoor and outdoor units.
Electrical noise may affect the operation.
