bolts into the unit’s hanging holes. Fasten 
them using the included washers and nuts 
(See Fig. 4.5).   
Fig. 4.5
NOTE: The bottom of the unit should be 
10 - 18mm (0.4-0.7”) 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 o.

 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 
oat switch. If the unit is tilted against the 
direction of condensate ows (the drainpipe 
side is raised), the oat 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.
