If you will install the unit on a wall-mounted
bracket, do the following:
Before installing a wall-mounted unit, make
sure that the wall is made of solid brick,
concrete, or 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
2. Pre-drill the holes for the expansion bolts.
3. Clean dust and debris away from the holes.
4. Place a washer and nut on the end of each
5. Thread the expansion bolts through the holes
in the mounting brackets, put the mounting
brackets in position, and hammer the
expansion bolts into the wall.
6. Check that the mounting brackets are level.
7. Carefully lift the unit and place its mounting
feet on the brackets.
8. Bolt the unit rmly to the brackets.
TO REDUCE VIBRATIONS OF WALL-
If allowed, you can install the wall-mounted
unit with rubber gaskets to reduce vibrations
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.
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

to install the unit until the safety issue is
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 1/8 in
(3 mm) 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.
