WIRING PRECAUTIONS
WARNING
BEFORE PERFORMING ANY ELECTRICAL WORK, READ THESE WARNINGS.
All wiring must comply with local and national
electrical codes, regulations and must be installed
by a licensed electrician.
All electrical connections must be made according
to the Electrical Connection Diagramlocated on
the panels of the indoor and outdoor units.
If there is a serious safety issue with the power
supply, stop work immediately. Explain your
reasoning to the client, and refuse to install the
unit until the safety issue is properly resolved.
Power voltage should be within 90-110% of rated
voltage. Insufficient power supply can cause
malfunction, electrical shock, or fire.
Installation of an external surge suppressor at the
outdoor disconnect is recommended.
If connecting power to fixed wiring, a switch or
circult breaker that disconnects all poles and
has a contact separation of at least 1/8in (3mm)
must be incorporated in the fixed wiring. The
qualified technician must use an approved
circuit breaker or switch.
Only connect the unit to an individual branch
circuit. Do not connect another appliance to that
outlet.
Make sure to properly ground the air conditioner.
Every wire must be firmly connected. Loose
wiring can cause the terminal to overheat,
resulting in product malfunction and possible fire.
Do not let wires touch or rest against
refrigerant tubing, the compressor, or any
moving parts within the unit.
If the unit has an auxiliary electric heater,
it must be installed at least 1 meter (40in)
away from any combustible materials.
To avoid getting an electric shock, never
touch the electrical components soon
after the power supply has been turned
off. After turning off the power, always
wait 10 minutes or more before you touch
the electrical components.
Make sure that you do not cross your
electrical wiring with your signal wiring.
This may cause distortion, interference or
possibly damage to circuit boards.
No other equipment should be connected
to the same power circuit.
Connect the outdoor wires before
connecting the indoor wires.
WARNING
BEFORE PERFORMING ANY
ELECTRICAL OR WIRING
WORK, TURN OFF THE MAIN
POWER TO THE SYSTEM.
