3. Clean dust and debris away from holes.
4. Place a washer and nut on the end of each expansion bolt.
5. Thread expansion bolts through holes in mounting brackets, put mounting
brackets in position, and hammer expansion bolts into the wall.
6. Check that the mounting brackets are level.
7. Carefully lift unit and place its mounting feet on brackets.

WARNING: ELECTRICAL HAZARD
 Before performing electrical work, read these regulations:
1. All wiring must comply with local and national
electrical codes, 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. Explain your reasoning to the
client, and refuse to install the unit until the safety
issue is properly resolved.
4. Power voltage should be within 90-110% of
rated voltage. Insuffi cient power supply can cause
malfunction, electrical shock, or fi re.
5. When connecting power to fi xed wiring, install a surge
protector and main power switch with a capacity of
1.5 times the maximum current of the unit.
6. When connecting power to fi xed 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 fi xed wiring. The licensed
electrician must use an approved/listed circuit
breaker.
7. Only connect the unit to an individual branch /
dedicated circuit. Do not connect another appliance
to that circuit.
8. Make sure to properly ground the outdoor unit.
9. Every wire must be fi rmly connected. Loose wiring can
cause the terminal to overheat, resulting in product
malfunction and possible fi re.
10. Do not let wires touch or rest against refrigerant
tubing, the compressor, or any moving parts within
the unit.
