Installation Procedures

This manual cannot completely illustrate all the properties of the products you bought. Please contact the local Carrier distributor
center if you have any question or request.
Please use standard tools according to the installation requirements.
Except the standard attached accessories of the series units, please prepare other accessories according to this
manual request.
1. Choose a suitable installation location. Indoor units should be installed in places that allow even circulation of hot
and cool air. 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 easily eroded), much oil(including mechanical oil) and steam; places where organic substance
solvent is frequently used; places where machines generate the high frequency electromagnetic waves (abnormal
condition will appear in the control system); places where there is high humidity near the door or windows (dew is
easily formed); and places where the special sprayer is frequently used.
Indoor
1. The distance between wind outlet port and the ground should not be more than 2.2m.
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, lines, and drainpipe.
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. 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 on the wall and put the connecting pipe and connecting thread into the PVC, which is purchased
at the local shop. With a slight downwards tilt towards the exterior, the gradient should be kept at least 1/100,
as shown in Fig. 1.
(2) Before cutting the hole, check if there are pipes or reinforcing steel bars at the rear of the hole. Making the
hole in the place where wires or pipes are should be avoided.
(3) Fix the unit support and change the connection pipes, connecting the shapes of wires and drainpipes so as
to let them go through the wall hole.
(4) When unit can be installed beside the wall, and be fixed with screw through the wall, the position should as
the Fig.2. Then, unit can be fixed with screw under the ground, the position should be as shown in Fig.3
