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 there is no risk of flammable gas leaking.
• The equipment is not intended for use in a potentially
explosive atmosphere.
• Where piping between indoor and outdoor units is possible within
the allowable limit. (Refer to the installation manual of the outdoor
unit.)
• This is a class A product. In a domestic environment this product
may cause radio interference in which case the user may be
required to take adequate measures.
• Keep indoor unit, outdoor unit, inter unit wiring and remote
controller 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 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 125 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 ( = air flow direction))
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.)
