E. WIRE CONNECTIONS
Before performing any electrical work, read these warnings.
Before any electrical or wiring work, turn off the main power to the system.
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 Diagram located 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 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.
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.
If the unit has an auxiliary electric heater, it must be installed at least 40 in (1 m) away from any combustible materials.
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.
