Notes to the installer

• 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 sure to fill out the appropriate installation specifications in
the chapter "What to do before operation" of the outdoor unit
operation manual.

SELECTING INSTALLATION SITE

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 installed on ceilings up to 3m in height.
3. 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.)
Space required for installation see figure 1.

PREPARATIONS BEFORE INSTALLATION

1. Relation of ceiling opening to unit and suspension bolt
position. (see figure 2)

5 Suspension pitch
6 Unit outside dimensions
7 Panel outside dimensions
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.
Installation example see figure 3.
1 Ceiling slab
