BEFORE PERFORMING ELECTRICAL WORK, READ THESE REGULATIONS
All wiring must comply with local and national electrical codes, and must be installed by a
1.
licensed electrician.
All electrical connections must be made according to the Electrical Connection Diagram
2.
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
3.
reasoning to the client and suspend all installation until the safety issue is properly resolved.
Power voltage should be within 90-110% of rated voltage. Insufficient power supply can
4.
cause malfunction, electrical shock, or fire.
Connect power through fixed wiring, install a surge protector and a disconnect switch box,
5.
and a dedicated circuit breaker with a capacity of 1.5 times the maximum current of the unit.
A properly rated HACR-type fuse or circuit breaker that disconnects all poles and
6.
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 fuse.
Only connect the unit to an individual branch circuit. Do not connect another appliance
7.
to that outlet. This equipment requires its own dedicated and protected circuit.
Make sure to properly ground the air conditioner.
8.
Every wire must be firmly connected. Loose wiring can cause the terminal to overheat,
9.
resulting in product malfunction and possible fire.
Do not let wires touch or rest against refrigerant tubing, the compressor, or any moving
10.
parts within the unit.
BEFORE PERFORMING ANY ELECTRICAL OR WIRING WORK,
