pipes with adhesive vinyl tape.
2) Be sure to connect the drain hose to the drain port in place
of a drain plug.
3) Shape the refrigerant pipe along the pipe path marking on
the mounting plate.
4) Pass drain hose and refrigerant pipes through the wall

the drain pipe.
The indoor unit must be installed in such a way so as to prevent short circuit of the cool discharged air with the
hot return air. Please follow the installation clearance shown in the figure. Do not place the indoor unit where there
could be direct sunlight shining on it. Also, this location must be suitable for piping and drainage, and be away
from doors or windows.
