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.
•
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.
