4 - INSTALLATION AND CONNECTIONS
To prevent injury or damage to the unit or room, the hydraulic connections must only be made by
qualified personnel.
4.1 - Mechanical connections
Ensure there are no obstacles in order to guarantee optimal air distribution.
An electrostatic film applied to the air intake prevents dust from entering the unit during assembly and can be left
in place until the diffuser is fitted in its final position.
The air handling box is placed inside the suspended ceiling, at the edge of the room with the air discharge opposite
windows and the electrical box facing the interior of the building for models with a Visual 180° return/discharge
panel (Fig. 4 - a).
For Visual 360 ° models, position the box in the centre of the room (Fig. 4 - b), with the electrics box oriented towards
the building's interior. Ensure that the neighbouring suspended ceiling panels can be easily removed to allow
maintenance and servicing operations to be carried out. To facilitate positioning of the unit, we recommend that
you remove one of the T-shaped profiles. The COADIS LINE™ must be suspended from the ceiling using 4 threaded
rods (not supplied) either 6 mm or 8 mm in diameter, which are fixed to the unit's 4 support brackets using antivibration
resilient mounts (optional, Fig. 3 - a) or a nut/washer assembly positioned on either side of the mounting bracket
(Fig. 3 - b)
Note: To enable access to the auxiliary condensate drain pan and to the electrical and hydraulic connections,
a flap must be provided or access must be possible via adjacent panels in the suspended ceiling.
CIAT strongly recommends the use of antivibration resilient mounts when securing the unit, in order to reduce the
transmission of vibrations through the building structure during operation.
The fitting template found in the air handling box packaging is used to trace the anchoring points for the threaded
rods onto the ceiling.
Insert the threaded rods in the notches on the support brackets.
The unit must be level and rest gently on the base of the T-shaped profiles in the suspended ceiling (Fig. 3 - c) or
between the profiles depending on the type of fitting (Fig. 3 - d).
■ Check that the impeller rotates freely and that there is no friction. If necessary, readjust the
plastic inlet (Fig. 9, a) fitted to the air intake under the main pan, by gently loosening the 3
mounting bolts (Fig. 9, b). This check must be performed each time the main condensate drain
pan is disassembled and before the unit is switched back on.
■ The unit must be perfectly level in relation to the suspended ceiling to prevent condensate
draining problems.
■
For configurations with a Visual 180°, return/discharge panel, the rear of the unit must be a
sufficient distance from the wall (at least 300 mm, recommended 600 mm) to allow suitable
access to the hydraulic, electrical and air connections.
■ Reminder: the air discharge is always directed towards glass partitions in order to minimise
heat flow due to radiation.
■ If a room thermostat is fitted, place it on an inside wall (not behind a door) and at a height of
1,50 m from the floor. Keep it away from sunlight and all sources of heat.
4.2 - Air connections
Air quality
Comfort units are not designed to control the humidity of outside air. Fresh air handling must be provided by an
independent system in accordance with accepted engineering practice (see CIAT air handling unit ranges).
