DUCTED INDOOR UNITS INSTALLATION
INSTALLATION OF THE INDOOR DUCTED UNIT
Requirements on the Installation Location
1. Ensure the hanger is strong enough to withstand the weight
of the unit.
2. The drainage pipe is easy for connection.
3. No obstacle is in the inlet/outlet and the air circulation is in
good condition.
4. Ensure the installation space is left for access to
maintenance.
5. It should be far away from where there is a heat source,
leakage of any inflammable, explosive substances, or smog.
6. It is the ceiling type unit (concealed in the ceiling).
7. The power cords and connection lines of the indoor and
outdoor units must be at least 1m away from the TV set or
radio to avoid the image interference and noise (even if 1m
is kept, the noise may be produced due to the strong
electromagnetic wave).
Installation of the Indoor Ducted
Unit
1. Insert the M10 expansion bolt into the hole, then knock the
nail into the bolt. Refer to the Outline Dimension Drawings
of the Indoor Unit for the distance between holes and see
Fig. 50 for the installation of the expansion bolt.

S Prior to the installation, make a good pre paration for a ll piping
(refrigerant pi pe, dr a in pi pe) and wir ing ( w i re s of the wired
controller, wi r es between the indoor a nd outdoor unit) of t he
indoor unit to make the fur ther inst allati on much easier.
S If there is an opening in the ceiling, its better to reinforce it
to keep it flat and prevent it from vibrating. Consult the user
and builder for more details.
S If the ceiling is not strong enough, the uni t ca n be se cured on
an angle iron beam.
S If the indoor unit is not installed in the air conditioning
area, place a sponge around the unit to prevent condensing.
The thickness of the sponge depends on the actual
installation environment.

CAUTION
INDOOR DUCTED UNIT HORIZONTAL CHECK
After the installation of the indoor unit, its horizontality must be
checked to make sure the unit keeps a horizontal fore and aft and
maintains an inclination of 5_ toward the drain pipe right and left,
as shown in Fig. 53.
