CIAT COADIS LINE 600 Manuel D'instructions page 36

Warning:
- 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).
● Fitting the Visual 180 ° or Visual 360 ° return/discharge panel:
We recommend fitting this component only when the box is already installed in the
suspended ceiling to prevent damage to the panel or clogging of the filter during tests
when switching on for the first time.
- Remove the electrostatic film applied to the box's air intake.
- Open and remove the intake grille on the nozzle (Fig. 5, a).
- Fit the panel (Fig. 5, b). Warning: for improved efficiency, direct the Visual 180°
nozzle towards the glass walls.
- Pivot the 4 bolts to hold the nozzle in position (Fig. 5, c).
- Tighten the 4 bolts (Fig. 5, d).
- Refit and close the intake grille again.
Attention: do not press hard on the corners of the panel as this could deform them.
Check that the panel is securely affixed.
The COADIS LINE has a directly integrated return/discharge interface which is able
to isolate the flow of air handled by the unit from the suspended ceiling. The use of a
connecting air duct between the air return and discharge is therefore not necessary.
The COADIS LINE has an inlet for clean fresh air equipped with a 100 mm diameter
connection sleeve integrated in the frame, with a removable plug (Fig. 6 - a).
Recommended max fresh air flow 90 m
When using the COADIS LINE with fresh air, as a filtration cassette according to
standard VDI 6022, the air handling unit must fulfil the criteria for this standard and
must be equipped with an F7 filter as a minimum.
