INSTALLATION INSTRUCTIONS
This manual cannot completely illustrate all the properties of the products that were purchased. Please contact the local
Haier distribution center if you have any question or request.
WARNING
Protect the machine from winds or earthquake and install according to regulations. Improper installation will cause
accidents due to unit coming loose and falling.
CAUTION
• Choose a suitable installation location.
• Avoid places with high salinity (salt water) and high sulfur gas. Unit will corrode and damage will not be covered
by warranty.
• Avoid excess oil (including mechanical oil) and steam. This can reduce efficiencies and product performance.
• Avoid areas where machines generate high frequency electromagnetic waves; this can cause control issues.
Installation information:
1. The distance between air outlet and the ground should
not be more than 8.8ft (2.7m).
2. Select appropriate places for installation where the
airflow can be spread evenly throughout the house.
Arrange proper locations for connecting pipes and lines
as well as the drainpipe to the outdoor.
3. Ceiling construction must be sturdy enough to hold the
weight of the unit.
4. Make sure that the connecting pipe, the drain pipe and
connecting refrigerant lines can be put through the
outside walls to connect the outdoor units.
5. Make the connecting pipe between the outdoor and
indoor units and the drainpipe as short as possible.
6. Please read the attached installation instructions for
outdoor unit refrigerant charging instructions.
7. The connecting flange should be checked by users.
8. Electrical appliances such as television, instruments,
devices, artwork, piano, wireless equipment and other
valuables should not be placed under the indoor unit to
avoid possible condensate from dripping onto them and
causing damage.
The following steps can be taken after selecting the installation place:
1. Cut a hole in the wall and insert connection pipe and connecting wires through a field
supplied PVC pipe. The hole should be inclined slightly downward with an inclination of
at least 1/100.
2. Before cutting the opening; ensure no pipe or rebar is placed behind the cutting
position. Avoid cutting the opening near wires or connection pipes.
3. Hang the unit on a horizontal and firm roof. If the unit base is not stable, it may cause noise, vibration or leakage.
4. Support the unit firmly and shape the connection pipe, connecting wires and drain pipe to allow them to easily get
through the opening.
