Installation Procedures

This manual cannot completely illustrate all the properties of the products you bought. Please contact the local Carrier
distribution center if you have any question or request.
Please use the standard tools listed in 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 a suitable installation location. Indoor units should be installed in places that allow
even circulation of cool and warm blows. The following places should be avoided.
Places with high salinity (beaches), high sulfureted gas(such as the thermal spring regions where copper tubes and
soft soldering can easily be eroded), excess oil (including mechanical oil) and steam; places where organic substance
solvents are frequently used; places where machines generate high frequency electromagnetic wave (abnormal
condition will appear in the control system); places with high humidity – for example near the door or windows (dew is
easily formed); and places where special sprayers are 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 flow all over the house. 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 that the connecting pipe between the outdoor and indoor units and the drainpipe should be as short
as possible.
6. Please read the attached installation instructions which regulate the amount of refrigerant that should be filled in
outdoor units when it becomes necessary.
7. The connecting flange should be inspected 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. This is important to prevent condensate from dropping over 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 through
pipes housing wires or any other 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.
Support the unit firmly. Change the shapes of connection pipe, connecting wires and drain pipe so they can easily
pass through the hole.
