CAUTION!
● Prior to the installation, please make a good preparation for all piping (refrigerant pipe,
drain pipe) and wring (wires of the wired controller, wires between the indoor and outdoor
unit) of the indoor unit to make the further installation much easy.
● If there is an opening in the ceiling, it is better to reinforce it to keep it flat and prevent it
vibrating. Consult the user and builder for more details.
● If the strength of the ceiling is not strong enough, abeam made of angle iron can be used
and then fix the unit on it.
● 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.
