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
circuit.
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.
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.

BEFORE PERFORMING ANY
ELECTRICAL OR WIRING WORK,
