S
ELECTING
INSTALLATION
SITE
(See
figure 1
and
4
)
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
interference in those electrical appliances.
(Electric noise may be generated depending on the conditions
under which the electric wave is generated, even if 1 meter is
kept.)
•
Never place anything under the indoor unit that you don't want to
get wet. The unit may sweat when the humidity is over 80% or
when the drain outlet is clogged.
•
Never place other heating equipment directly beneath the indoor
unit. Subject to deformation caused by heat.
•
The unit should be installed at least 2.5 m from the floor.
2.
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.
P
REPARATIONS
BEFORE
INSTALLATION
1.
Suspension bolt position.
(See figure 6)
For other installation than standard installation, contact your
Daikin dealer for details.
2.
The fan speed for this indoor unit is preset to provide high
external static pressure.
If lower external static pressure is required, reset the external
static pressure by changing the initial setting from the remote
controller.
Refer to
"Setting of static pressure" on page 5
.
3.
Install the suspension bolts.
(Use M10 size bolt for the suspension 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.
