Notes to the installer
I
Read this manual carefully to ensure correct installation. Be sure
to instruct the customer how to properly operate the system and
show him/her the enclosed operation manual.
Explain to the customer what system is installed on the site. Be
I
sure to fill out the appropriate installation specifications in the
chapter "What to do before operation" of the outdoor unit
operation manual.
S
ELECTING INSTALLATION SITE
When the conditions in the ceiling are exceeding 30°C and a relative
humidity of 80%, or when fresh air is inducted into the ceiling, an
additional insulation is required (minimum 10 mm thickness,
polyethylene foam).
For this unit you can select different air flow directions. It is necessary
to purchase an optional blocking pad kit to discharge the air in 2 or 3
directions.
1
Select an installation site where the following conditions
are fulfilled and that meets your customer's approval.
•
Where optimum air distribution can be ensured.
•
Where nothing blocks air passage.
•
Where condensate water can be properly drained.
•
Where the false ceiling is not noticeably on an incline.
•
Where sufficient clearance for maintenance and service can be
ensured.
•
Where piping between indoor and outdoor units is possible within
the allowable limit. (Refer to the installation manual of the outdoor
unit.)
•
Keep indoor unit, outdoor unit, power supply wiring and
transmission wiring at least 1 meter away from televisions and
radios. This is to prevent image interference and noise in those
electrical appliances.
(Noise may be generated depending on the conditions under
which the electric wave is generated, even if 1 meter is kept.)
2
Ceiling height
This indoor unit may be installed on ceilings up to 3.5 m in height
(for 80~125 units: 4.2 m). However, it becomes necessary to
make field settings by the remote controller when installing the
unit at a height over 2.7 m (for 80~125 units: 3.2 m). To avoid
accidental touching, it is recommended to install the unit higher
than 2.5 m.
Refer to the chapter "Field setting" and to the decoration panel
installation manual.
3
Air flow directions
Select the air flow directions best suited to the room and point of
installation. (For air discharge in 2 or 3 directions, it is necessary
to make field settings by means of the remote controller and to
close the air outlet(s). Refer to the installation manual of the
optional blocking pad kit and to the chapter "Field setting".) (See
figure 1 (
= air flow direction))

Use suspension bolts for installation. Check whether the
ceiling is strong enough to support the weight of the indoor
unit. If there is a risk, reinforce the ceiling before installing
the unit.
(The installation pitch is marked on the paper pattern for
installation. Refer to it to check for points requiring reinforcing.)

Ceiling-panel overlapping dimension
Installation is possible with a ceiling dimension of
NOTE
910 mm (marked with*). However, to achieve a ceiling-
panel overlapping dimension of 20 mm, the spacing
between the ceiling and the unit should be 35 mm or
less. If the spacing between ceiling and the unit is over
35 mm, attach ceiling material to the part or recover
the ceiling.
2.
Make the ceiling opening needed for installation where
applicable. (For existing ceilings.)
•
Refer to the paper pattern for installation for the ceiling opening
dimensions.
•
Create the ceiling opening required for installation. From the side
of the opening to the casing outlet, implement the refrigerant and
drain piping and wiring for remote controller (unnecessary for
wireless type) and indoor-outdoor unit casing outlet. Refer to
each piping or wiring section.
•
After making an opening in the ceiling, it may be necessary to
reinforce ceiling beams to keep the ceiling level and to prevent it
from vibrating. Consult the builder for details.
3.
Install the suspension bolts. (use either a W3/8 or M10 size bolt.)
Use anchors for existing ceilings, and a sunken insert, sunken
anchors or other field supplied parts for new ceilings to reinforce the
ceiling in order to bear the weight of the unit. Adjust clearance from
the ceiling before proceeding further.
