Wiring
BEFORE PERFORMING ANY
ELECTRICAL WORK, READ THESE
REGULATIONS
1. All wiring must comply with local and national
electrical codes, regulations and must be
installed by a licensed electrician.
2. All electrical connections must be made
according to the Electrical Connection Diagram
located on the panels of the indoor and outdoor
units.
3. 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.
4. Power voltage should be within 90-110% of
rated voltage. Insufficient power supply can
cause malfunction, electrical shock, or fire.
5. If connecting power to fixed wiring, install a
surge protector and main power switch with
a capacity of 1.5 times the maximum current
of the unit.
6. If connecting power to fixed wiring, a switch
or circuit 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.
14. The unit must be connected to the
main outlet. Normally, the power supply
must have a impedance of 32 ohms.
15. No other equipment should be
connected to the same power circuit.
16. Connect the outdoor wires before
connecting the indoor wires.
7. Only connect the unit to an individual
branch circuit outlet. Do not connect
another appliance to that outlet.
8. Make sure to properly ground the air
conditioner.
9. 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 mustbe installed at least 1 meter (40in)
away from any combustible materials.

Wiring
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 and
interference.
