1.
Mark the position of bracket holes based on
dimensions in the Unit Mounting Dimensions
chart.
2. Pre-drill the holes for the expansion bolts.
3. Clean dust and debris away from holes.
4. Use plug and bolt / screw made for walls to
screw the wall bracket.
5. Check that the mounting brackets are level.
6. Carefully lift unit and place its mounting feet on
brackets.
7. Bolt the unit firmly to the brackets.
1.
All wiring must comply with local and nation-
al 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 side panels of the indoor and outdoor units.
3. If there is a serious safety issue with the power
supply, stop work immediately. Explain your rea-
soning to the client, and refuse to install the unit
until the safety issue is properly resolved.
4. Power voltage should be within 90-100% of rat-
ed voltage. Insufficient power supply can cause
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 1/8in (3mm) must
be incorporated in the fixed wiring. The 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 wir-
ing 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 1 meter (40in) away from any
combustible materials.
To install the unit on the wall, do the following:
TO REDUCE VIBRATIONS OF
WALLMOUNTED UNIT
OUTDOOR UNIT INSTALLATION
If allowed, you can install the wall-mounted unit with rubber
gaskets to reduce vibrations and noise.
Before installing a wall-mounted unit, make sure that the wall
is made of solid brick, concrete, or of similarly strong material.
The wall must be able to support at least four times the
weight of the unit.
The outside unit’s terminal block is protected by an electrical
wiring cover on the side of the unit. A comprehensive wiring
diagram is printed on the inside of the wiring cover.
