WARNING
G
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.).
G
Each wire must be firmly connected.
G
No wire should be allowed to touch refrigerant
tubing, the compressor, or any moving part.
G
Be sure to connect power wires correctly
matching up numbers on terminals of the
outdoor unit and respective indoor units A – D.
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
1 meter 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 2 meters
away from other grounds and do not have it
shared with other electric appliances.
