ELECTRICAL CONNECTIONS
NOTE: 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 indoor and outdoor unit
panels.
3. It there is a serious safety issue with the power supply, stop work
immediately. Resolve the issue before proceeding with the
installation.
4. Power voltage should be 90-110% of the rated voltage. An
insufficient power supply can cause a malfunction, electrical shock
or fire.
5. If connecting power to fixed wiring, a surge protector and main
power switch should be installed.
6. If connecting power to fixed wiring, a switch or a circuit breaker
that disconnects all poles and has a contact separation of at least 1/
8in(3mm) must be incorporated in the secured wiring. The
qualified 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. 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 the wires to touch or rest against the refrigerant
tubing, the compressor, or any moving parts within the unit.
11. To avoid an electrical shock, refrain from touching the electrical
components shortly after the power supply has been turned on.
After turning off the power, always wait at least ten minutes before
touching electrical components.
12. Ensure you do not cross electrical wiring with signal wiring. Doing
so may cause distortion and interference.
13. The unit must be connected to the main outlet. Normally the power
supply must have a impedance of 32 ohms.
14. No other equipment should be connected to the same power
circuit.
15. Connect the outdoor wires before connecting the indoor wires.
NOTE: In North America, the appliance should be wired according
to NEC and CEC requirements.
