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 xed wiring, a
surgeprotector and main power switch should
be installed.
6. If connecting power to xed 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 xed wiring.
The qualied technician must use an approved
circuit breaker or switch.
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.
10. Do not let wires touch or rest against
refrigerant tubing, the compressor, or any
moving parts within the unit.
11. If the unit has an auxiliary electric heater, it
must be installed at least 1 meter (40in) away
from any combustible materials.
12. 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.

13. Make sure that you do not cross your electrical
wiring with your signal wiring. This may cause
distortion and interference.
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.
