Install the indoor unit on the ceiling:
CAUTION:
a. Prior to the installation, please make a good preparation for all piping (refrigerant pipe, drain pipe) and wiring
(wires of the wired controller, wires between the indoor and outdoor unit) of the indoor unit to make the further installation
much easier.
b. If there is an opening in the ceiling, it is better to reinforce it to keep it at and prevent it vibrating. Consult the
user and builder for more details.
c. If the strength of the ceiling is not strong enough, a beam made of angle iron can be used and then x the unit on
it.
d. If the indoor unit is not installed in the air conditioning area, please use sponge around the unit to prevent
condensing. The thickness of the sponge depends on the actual installation environment.
4.1.6 Horizontality Check of the Indoor Unit
After the installation of the indoor unit, its horizontality must be checked to make sure the unit keep horizontal fore
and aft and keep an inclination of 5° toward the drain pipe right and left.
