Haier AE072FEAHA Installation Manual - page 9
Refrigerant piping
In order to drain water normally, the drain pipe shall be processed as specified in the installation
manual and shall be thermal insulated to avoid dew generation. Improper hose connection may
cause indoor water leakage.
Requirements
The indoor drain pipe shall be thermal insulated.
The connection part between the drain pipe and the indoor unit shall be insulated so as to
prevent dew generation.
The drain pipe shall be slant downwards (greater than 1/100). The middle part shall not be of
S type elbow, otherwise abnormal sound will be produced.
The horizontal length of the drain pipe shall be less than 20 m. In case of long pipe, supports
shall be provided every 1.5 - 2m to prevent wavy form.
Central piping shall be laid out according to the following figure.
Take care not to apply external force onto the drain pipe connection part.
Pipe and insulation material
Rigid PVC pipe VP31.5mm (internal diameter)
Foamed PE with thickness above 7 mm

Hose
Drain pipe size: 19.05mm (3/4") PVC pipe
The hose is used for adjusting the off-center and angle of the rigid PVC pipe.
Directly stretch the hose to install without making any deformation.
The soft end of the hose must be fastened with a hose clamp.
Please apply the hose on horizontal part
Insulation treatment:
Wrap the hose and its clamp until to the
indoor unit without any clearance with
insulating material, as shown in the figure.
Drain confirmation
During trial operation, check that there is no leakage at the pipe connection part during water
draining even in winter.

The electric wiring work shall be conducted by qualified electricians according to the installation
instructions. A separate power circuit shall be used. Insufficient power cord amperage or improper
wiring will cause danger of electric shock or fire.
During wiring connection, the power cord shall be of the specified cable and reliably fastened
so that external forces applied to the cable wouldn't transfer to the terminals. Improper connection
or fastening will cause danger of heating, fire etc.The power cord must be fitted with a grounding
wire.
Grounding shall be made as specified. Unreliable grounding will cause electric shock. The
grounding wire shall not be connected to the gas pipeline, water pipeline, thunder arrestor and
telephone wire.
! Warning
Electrical wiring
The specifications are listed in the table below. Smaller capacity may cause overheat or burnout.
