12cm-15.5cm (4.7"-6.1") deep at
the ceiling hook positions in the
internal ceiling. Be sure to hold the
drill at a 90° angle to the ceiling.

hooks into the pre-drilled holes.
Secure the bolt using the
included washers and nuts.
4. Install the four suspension bolts
(See Fig. 3.4).

NOTE: The bottom of the unit should be
10 - 25mm (0.4-0.98") for 24k-60k models
or 24mm (0.9") for 12k-18k models higher
than the ceiling board. Generally, L (indicated
in Fig. 3.6) should be half the length of the
suspension bolt or long
enough to prevent the nuts from coming off.

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.
