SELECTING INSTALLATION SITE
When the conditions in the ceiling exceed
300˚C/860˚F and a relative humidity of
80%, or when fresh air is inducted into
the ceiling, an additional insulation is
required (minimum 10mm/0.4" thickness,
polyethylene foam).
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.)
• Keep indoor unit, outdoor unit, unit
wiring
and remote control wiring at least 40"
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 40"is kept.)
CEILING HEIGHT
• Install this unit where the height of
bottom panel is more than 2.5m/8.2'
so that the user cannot easily touch.
USE INSTALLATION HOOKS 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.
• Space required for installation see the
figure below ( air flow direction)

to support the weight of the unit, the unit could be
out of place and cause serious injury.
