Preparation Before Installation - Daikin FDMA125AV16 Installation Manual

<Failure example>
If there is an obstacle in the airflow path or proper installation
space is not provided, the indoor unit will cause air volume
reduction and take in air blown out of the indoor unit,
thus resulting in performance degradation or turning the
thermostat OFF frequently.

CAUTION
• Install the indoor and outdoor units, power supply wiring,
remote controller wiring and transmission wiring at least
1 meter away from televisions or radios to prevent image
interference or noise.
(Depending on the radio waves, a distance of 1 meter may
not be sufficient to eliminate the noise.)
• Install the indoor units as far as possible from fluorescent
lamps.
(2) Use hanging bolts for installation.
Investigate if the installation place can withstand the mass
of the indoor unit and if necessary, hang the indoor unit
with bolts after it is reinforced by beams etc.

4. PREPARATION BEFORE INSTALLATION

(1) Check the relation of location between the ceiling
opening and the indoor unit hanging bolts.
• Provide one of the following service spaces for the
maintenance and inspection of the control box and
drain pump or for other services.
1. Inspection hatch 1 and 2 (450 x 450) for the
el. compo. box and a minimum space of 300 mm at the
bottom of the product. (Refer Fig. 2-2)
2. Inspection hatch 1 (450 x 450) on the control box side
and inspection hatch 2 on the bottom of the
product.(Fig. 2-3, arrow A-1)
3. Inspection hatch 3 on the bottom of the product and on
the bottom side of the control box, see direction view

(2) Mount canvas ducts to the air outlet and inlet so that
the vibration of the indoor unit will not be transmitted
to the ducts or ceiling. Furthermore, attach sound
absorbing material (thermal insulation material) to the
duct inner walls and anti-vibration rubber to the hanging
bolts (refer to 8. DUCT WORK).
(3) The indoor unit is set to standard external static
pressure.
• If external static pressure is higher or lower than the
standard set value, the remote controller may be used to
make on-site setting change in the external static pressure.
