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

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).
