CAUTION
Ensure that the unit is completely level.
Improper installation can cause the drain pipe to back up into the unit or
water leakage.
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.
