10. Installation
Installing on a new ceiling
1
Place the pattern sheet on the ceiling at the spot
where you want to install the fan coil unit.
NOTE
• Because the pattern sheet is made of paper, it may
shrink or stretch slightly due to temperature or
humidity.
Take the following steps to install one or more inspection
holes according to the panel type.
•
For installing a ceiling type square panel
Install an inspection hole along the direction of
connection parts of the water pipe and the drain hose.

•
For installing a ceiling type circular panel
Install an inspection hole along direction of the
connection parts of the water pipe and the drain hose and
another along the direction of the fan coil unit display.

Drill holes on the ceiling or the ceiling support, and
then insert the foundation bolts, as shown in the
following figure:

Install suspension bolts, depending on the ceiling
conditions.
• Before hanging the fan coil unit, make sure that the
ceiling is strong enough to support the weight of
the unit. Test the strength of each suspension bolt
installed.
• Install the suspension bolts in various ways suitable
for the type and material of the ceiling. Anti-
vibration treatment is required when the ceiling
fixing bolt is 1.5 m or more.

Secure a total of 8 nuts and washers to each
suspension bolt. However, leave a little space between
the nuts into which the hanger bracket of the fan coil
unit will be inserted.
• At this time, if you cut the stopper pad and insert
it under the upper washer, the washer will not flow
down, making the installation easier.
• For installation of the fan coil unit, be sure to install
at least four suspension bolts.

Insert a hanger bracket between the nuts fixed to each
suspension bolt to hang the fan coil unit.
• When installing the product, be sure to install the
piping inside the ceiling. When an existing ceiling
is used, install the piping inside the ceiling before
installing the fan coil unit.

Tighten the nuts to firmly fasten the fan coil unit.
7
Adjust the position of the fan coil unit while
considering the space for installing the front panel.
• Remove the jig made in the pattern sheet, and then
use the jig to adjust the space between the ceiling
and the fan coil unit, as shown in the figure below.
• If not installed in alignment with the jig, noise may
occur.
• Adjust the position of the fan coil unit in alignment
with the jig.
• Adjust the level of the fan coil unit by using a
leveler, and then fix the unit securely.
• First, fix the front panel with the panel fixing bolts,
and then install the front panel so that it comes in
close contact with the fan coil unit body.
