Installation Procedures
This manual cannot completely illustrate all the properties of the products you bought. Please contact the local Haier
distribution center if you have any question or request.
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. They can cause control issues.
Warning:
protect the machine from winds or earthquake, install according to regulations. Improper installation will cause accidents
due to unit coming loose and falling.
Indoor Units
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 drainpipe and
connecting guide line can be put into walls to connect the
outdoor units.
5. It is recommended to make the connecting pipe between
the outdoor and indoor units and the drainpipe as short as
possible.
6. Please read the attached installation instruction of the
outdoor unit for refrigerant charging if necessary.
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 as to
prevent condensate from dropping 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 (see Figure 1).
2. Before cutting the hole, ensure no pipe or rebar is placed behind the cutting position. Avoid cutting a hole 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 hole.
