If units are equipped with TRANE control, then a corresponding warning message is dis-
played on the HMI (see
) when the differential pressure limitation is reached.

Warning message filter
If such a warning message is displayed, then appropriate actions have to be taken immedi-
ately (e.g. change of air filters).
9.3.1 Panel filters
Dry panel air filters (cleanable). The contamination level of the filter can be controlled by the
differential pressure drop (check every 14 days to 1 month). Reaching the pressure differ-
ence indicated in the technical data sheet, cleaning or replacement is required.
Cleaning:
-
Dirty filters dismount, tapping, suck off with a vacuum cleaner or clean it with air pressure
(max. 5 bar).
-
Wash the filter in max.35° C warm water with mild commercial detergent, then rinse thor-
oughly.
-
Let fatty filters about 1h in suds.
-
Not wrestle cleaned filter, let filters drain before mounting. The synthetic fibers dry quickly
and can be installed and put back into service also if they are still wet.
-
Clean also the filter section before remounting the filters, check filter tightness and reseal
if necessary.
-
Filters can be cleaned 2-3 times then a replacement of the filters is necessary.
Seals for panel filters and soft bag filters
Seals are self-adhesive and are supplied loose. Sealing: only the front side, only 1 sealing
stripe…
-
between the filters,
-
between filter and door,
-
between wall and filter.
