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 hanging
screw bolts with a block. Position the indoor
unit flat using a level indicator to prevent
leaks.
