Servicing And Maintenance; Air Filter; Condensate Drain Pans - CIAT COADIS LINE 600 Instruction Manual

5 - SERVICING AND MAINTENANCE

The unit must be serviced periodically between the heating and cooling seasons. In particular, components prone
to clogging (filter, condensate drain pan, coil, etc.) must be checked.
Disconnect the electrical supply to the unit before carrying out any work. The hydraulic circuit must also be closed.

5.1 - Air filter

The COADIS LINE™ is equipped as standard with an "EPURE" high-efficiency pleated filter.
The filter is crucial to the correct operation of the unit. Without it the heat exchange coil would become clogged,
the performance drop and the unit's sound level rise.
CIAT recommends regular inspections of the filter's appearance in order to define the frequency with which it should
be replaced, which varies depending on the premises and the operating conditions (replacement at least every two
years). If maintenance is carried out more frequently, the filter can be cleaned by running a vacuum attachment (in
the opposite direction to the flow of air). The above recommendations are for information only.
To guarantee optimal thermal, acoustic and air purification efficiency throughout the unit's life, CIAT recommends
the use of an "EPURE" filter. Using a different type of filtration system could compromise the performance of the
unit and be detrimental to users.
Accessing the filter:
■ Mark the two retaining lugs (Fig. 16, a) positioned on the micro perforated return air grille
■ Push the two lugs to release the return air grille.
■ Lower the hinge-mounted return air grille until it is at right angles to the diffuser.
■ Release the filter from its housing.
■ After fitting a new filter, refit the return air grille. Lock it near to the panel by simultaneously pushing the two lugs
sharply upwards.
■ Check that the grille is securely affixed.
Note: the micro perforated return air grille must never be pushed in beyond the discharge panel.

5.2 - Condensate drain pans

The main and auxiliary condensate drain pans must be kept clean. The pans and drainage fittings may be completely
cleaned using non-abrasive, water-based detergents. Also check periodically that the drain pipe is not blocked.
When using the COADIS LINE™ as a filtration cassette, according to standard VDI 6022, it is essential to clean
the drain pan.
Removing the pans:
■ To remove the auxiliary pan:
- Unscrew the bolt under the pan (Fig. 17, b).
- Then unclip it from its location.
- Refit the bolt on the cassette (Fig. 17, a).
■ To remove the main pan.
- Open and remove the intake grille on the nozzle (Fig. 18, a).
- Loosen the 4 bolts (Fig. 18, d).
- Pivot the 4 bolts holding the nozzle in position (Fig. 18, c).
- Remove the panel (Fig. 18, d).
- Remove the 4 brackets (8 bolts) (Fig. 18, e)
- Swivel the pan (approximately 30°) downwards (Fig. 18, f) and release it from its retaining lugs. (Fig. 18, g)
To refit, perform the operation in reverse order.
