For the following items, take special care during 
construction and check after installation is finished

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.

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, 3 or
4 (closed corners) 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 there is no risk of flammable gas leaking.

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, inter unit wiring and remote
controller 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.)

When installing the wireless remote controller kit, the distance
between wireless remote controller and indoor unit might be
shorter if there are fluorescent lights who are electrically started
in the room. The indoor unit must be installed as far as possible
away from fluorescent lights.

2

Ceiling height

This indoor unit may be installed on ceilings up to 3.5 m in
height (for FCQH100~140 units: 4.2 m). However, it becomes
necessary to make field settings using the remote controller
when installing the unit at a height over 2.7 

m (for

FCQH100~140 units: 3.2 m).
To  avoid accidental touching, it is recommended to install the
unit higher than 2.5 m.
Refer to 

"Field setting" on page 8

  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 

"Field setting" on page 8

(See

figure 1)

 (

4

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.)
