CAUTION
The unit body must be completely
aligned with the hole. Ensure that
the unit and the hole are the same
size before moving on.
2. Install and fit pipes and wires after you
have finished installing the main body.
When choosing
where to start, determine
the direction of the pipes to be drawn out.
Especially in cases where there is a ceiling
involved, align the refrigerant pipes, drain
pipes, and indoor and outdoor lines with
their connection points before mounting
the unit.
3. Install hanging screw bolts.
Cut off the roof beam.
Strengthen the point at which the
cut was made. Consolidate the
roof beam.
4. After you select an installation
location, align the refrigerant pipes,
drain pipes, as well as indoor and
outdoor wires with their connection
points before mounting the unit.
5. Drill 4 holes 10cm (4”) deep at the
ceiling hook positions in the internal
ceiling. Be sure to hold the drill at a
90° angle to the ceiling.
6. Secure the bolt using the washers
and nuts provided.
7. Install the four suspension bolts.
8. Mount the indoor unit with at least
two people to lift and secure it. Insert
suspension bolts into the unit’s
hanging holes. Fasten them using
the washers and nuts provided.
9. Mount the indoor unit onto the han-
ging screw bolts with a block. Position
the indoor unit flat using a level
indicator to prevent leaks.
