Haier AE072FEAHA Installation Manual - page 8
Installing the suspension screw:
Use M8 or M10 suspension screws (4,prepared in the field)(when the suspension screw
height exceeds 0.9m,M10 size is the only choice).These screws shall be installed as
follows with space adapting to air conditioner overall dimensions according to the original
building structures.
Wooden structure
A square wood shall be supported by the beams and then set the suspension screws.
New concrete slab
To set with embedded parts,foundation bolts etc.
Original concrete slad
Use hole hinge,hole plunger or hole bolt.
Steel reinforcement structure
Use steel angle or new support steel angle directly.
Hanging of the indoor unit
Fasten the nut on the suspension screw and then hang the suspension screw in the T
slot of the suspension part of the unit.
Aided with a level meter,adjust level of the unit within 5mm

The indoor and outdoor units should use separate special power lines.
The leak breaker and indoor switch using the same outdoor unit
should use the same power.
Indoor power
The remote controller wire is polarized 3-core
wires
.
The grouped remote controller wire (between the indoor
and indoor units) is polarized 2-core wires. (Fig. 2)
Central controller communication wiring
The centralized controller communication wire are non-
polarity 2-core wires.
To prevent electromagnetic disturbance, please use
shielded wires.
Remote controller wiring
(Fig.1)
The remote controller wire is low voltage circuit, which should not be connected to 220-230V
or 380-400V power line. It should not share the same wire pipe with the power cable.
The wire is round 3-core chielded wire, which can be extended to 200m if the diameter is
0.75mm

and extended to 500m if the diameter is 1mm

.
Remote controller wiring
Wiring should be done according to the number of the block terminal
