Installation Manual

If you will install the unit on a wall-mounted
bracket, do the following:
CAUTION
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.
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. 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.
8. Bolt the unit rmly to the brackets.
TO REDUCE VIBRATIONS OF WALL-
MOUNTED UNIT
If allowed, you can install the wall-mounted
unit with rubber gaskets to reduce vibrations
and noise.
Step 4: Connect signal and power cables
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.
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 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 reasoning 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
rated voltage. Insufficient power supply can
cause electrical shock or fire.
5. If connecting power to xed 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 rmly connected. Loose
wiring can cause the terminal to overheat,
resulting in product malfunction and possible
re.
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 40in (1 meter) away
from any combustible materials.
