STEP 6: CONNECT SIGNAL CABLE
BEFORE PERFORMING ANY ELECTRICAL WORK, READ THESE REGULATIONS
1. All wiring must comply with local and national electrical codes and 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 and contact a
licensed electrician. Do not continue with the installation 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 1/8" (3mm) must be incorporated in the fixed wiring. A 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. 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 40" 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.

Before performing any electrical or wiring work, turn off the main power to the system.
