Precautions for unfavorable installation:
The preparation of all pipes (connecting pipes and drainage pipes) and cables (connecting lines of
wire controller, indoor unit and outdoor unit) must be ready before the installation, so as to achieve smooth
installation.
Drill an opening on the ceiling. Maybe it is required to support the ceiling to ensure the evenness of it
and avoid the vibration of it. Consult with the user or a construction company for details.
In case the strength of ceiling is not enough, use angle iron sections to set up a beam support. Place
the unit at the beam and fix it.
Level inspection of the indoor unit
After the indoor unit is installed, it is required to check the level of the whole unit. The unit must be
placed horizontally, but the condensate pipe shall be installed obliquely, so as to facilitate the drainage of
condensate.
