ELECTRICAL CONNECTIONS
Please read all power regulations on this page. We recommend having a
qualified electrician connect power to the unit.
BEFORE PERFORMING ELECTRICAL WORK, READ THESE REGULATIONS.
• All wiring must comply with local and national electrical codes and must be installed by a licensed
electrician.
• All electrical connections must be made according to the Electrical Connection Diagram located on the side
panels of the indoor and outdoor units.
• If there is a serious safety issue with the power supply, stop work immediately.
• Power voltage should be within 90%–110% of rated voltage. Insufficient power supply can cause electrical
shock or fire.
• 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.
• 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 in. (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 outlet. 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.
