NOTE:
The bottom of the unit should be
10-25mm(0.4-0.98”)higher than the ceiling
board. Generally, L (indicated in the following
figure) 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 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.
Step 3: Drill wall hole for connective piping
1. Determine the location of the wall hole
based on the location of the outdoor unit.
2. Using a 65mm (2.56”) or 90mm(3.54”)
(depending on models )core drill, drill a
hole in the wall. Make sure that the hole
is drilled at a slight downward angle, so
that the outdoor end of the hole is lower
than the indoor end by about 12mm (0.5”).
This will ensure proper water drainage.
3. Place the protective wall cuff in the hole. This
protects the edges of the hole and will help
seal it when you finish the installation process.
