Indoor Unit
Installation
CAUTION
The unit body should align perfectly with the
hole. Ensure that the unit and the hole are the
same size before moving on.
2. Drill 4 holes 5cm (2”) deep at the ceiling hook
positions in the internal ceiling. Be sure to hold
the drill at a 90° angle to the ceiling.
3. Using a hammer, insert the ceiling hooks into
the pre-drilled holes. Secure the bolt using the
included washers and nuts.
4. Install the four suspension bolts.
5. Mount the indoor unit. You will need two
people to lift and secure it. Insert suspension
bolts into the unit’s hanging holes. Fasten
them using the included washers and nuts.
NOTE:
The bottom of the unit should be
10-18mm(0.4-0.7”)(
Slim models
) or
24mm
(0.9”)(Compact models) 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.
Water level
CAUTION
Ensure that the unit is completely level.
Improper installation can cause the drain pipe
to back up into the unit or water leakage.
