NOTE
The bottom of the unit should be 10 - 18mm higher than
the ceiling board. Generally, L (indicated in Fig. 4.6) should
be half the length of the suspension bolt or long enough to
prevent the nuts from coming off.
NOTE
Ensure that the indoor unit is 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.
CAUTION
•
Ensure that the unit is completely level.
•
Improper installation can cause the drain pipe to back
up into the unit or water leakage.
