If you will install the unit on a wall-mounted
bracket , do the following:
CAUTION
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 chart.
2. Pre-drill the holes for the expansion bolts.
3. Place a washer and nut on the end of each
expansion bolt.
4. Thread expansion bolts through holes in
mounting brackets, put mounting brackets
in position, and hammer expansion bolts into
the wall.
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.
8. If allowed, install the 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.

CHOOSE THE RIGHT CABLE SIZE
The size of the power supply cable, signal cable,
fuse, and switch needed is determined by the
maximum current of the unit. The maximum
current is indicated on the nameplate located on
the side panel of the unit. Refer to this nameplate
to choose the right cable, fuse, or switch.
a. Using wire strippers, strip the rubber
jacket from both ends of cable to reveal
about 40mm (1.57in) of the wires inside.
b. Strip the insulation from the ends of the
wires.
c. Using a wire crimper, crimp u-lugs on the
ends of the wires.
ATTENTION TO LIVE WIRE
PAY
While crimping wires, make sure you clearly
distinguish the Live ("L") Wire from other wires.
WARNING
ALL WIRING WORK MUST BE PERFORMED
STRICTLY IN ACCORDANCE WITH THE
WIRING DIAGRAM LOCATED INSIDE OF
WIRE COVER OF THE OUTDOOR UNIT .
2. Unscrew the electrical wiring cover and remove it.
3. Unscrew the cable clamp below the terminal
block and place it to the side.
4. Connect the wire according to the wiring
diagram, and firmly screw the u-lug of each
wire to its corresponding terminal.
5. After checking to make sure every connection is
secure, loop the wires around to prevent rain
water from flowing into the terminal.
6. Using the cable clamp, fasten the cable to the
unit. Screw the cable clamp down tightly.
7. Insulate unused wires with PVC electrical tape.
Arrange them so that they do not touch any
electrical or metal parts.
