7.9.4 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.
Please use the standard tools according to the installation requirements.
The standard attached accessories of the units of this series refer to the packing list; prepare other accessories
according to the requirements of the local installation point of our company.
1.Choose the suitable installation location. Indoor units should be installed in places with the environment
of even circulation of cool and warm blows. The following places should be avoided.
Places with high salinity (beach), high sulfureted gas(such as the thermal spring regions where copper tubes
and soft soldering are easy to be eroded), much oil(including mechanical oil) and steam; places where organic
substance solvent is frequently used; places where machines generate the high frequency electromagnetic wave
(abnormal condition will appear in the control system); places where there is high humidity exists near the door or
windows (dew is easily formed); and places where the special sprayer is frequently used.
Indoor Units
1. The distance between wind outlet port and the ground should not be more than 2.7m.
2. Select appropriate places for installation where the outlet air can be spread to places all over the house and
arrange proper locations for connecting pipes and lines as well as the drainpipe to the outdoor.
3. Ceiling construction must be hard 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 are as
short as possible.
6. Please read the attached installation instruction of outdoor units for regulation of filling amount of refrigerant if
necessary.
7. The connecting flange should be checked by users.
8. Those 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 into them and
causing damage.
2.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 locally purchased 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 at the place of 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 change the shapes of connection pipe, connecting wires and drain pipe to make
them easily get through the hole.
3.Dimension (unit: mm).
