CAUTION:
Ensure that the unit is completely level.
The unit is equipped with a built-in drain pump and
float switch. If the unit is tilted against the direction of
condensate flows (the drainpipe side is raised), the float
switch may malfunction and cause water to leak.
NOTE FOR NEW HOME INSTALLATION
When installing the unit in a new home, the
ceiling hooks can be embedded in advance.
Make sure that the hooks do not come loose
due to concrete shrinkage. After installing the
indoor unit, fasten the installation paper
template onto the unit with bolts (M6X12) to
determine in advance the dimension and
position of the opening on the ceiling. Follow
the instructions above for the remainder of the
installation.
