Filter Dirty filters make the unit less effective. It is therefore neces-
sary to clean or replace the filters at regular intervals. The
contamination of filters is measured with the optional filter
sensor or calculated on the basis of the lifespan.
With the optional filter sensor, the unit measures the filter
contamination every 24 hours by running the fans at the high-
est speed for 40 seconds. In this menu, you can set the time at
which this check should be carried out.
Warning:
w
As default, the check is carried out at 00:00
a.m. (midnight). Be aware that the airflow of
the unit can set objects in motion. This might
set off an alarm system in the building at
night time.
The cleaning interval can be adjusted to match the actual con-
tamination of the filters.
The lifespan of the filter is calculated on the basis of the usage
of the unit if no filter sensor has been installed. You can adjust
this by setting the maximum lifespan of the filter.
When the filters are contaminated or when the maximum
lifespan is reached, a message appears on the Home screen.
Also, a signal can be generated on one of the outputs.
You can clean the filter with a vacuum cleaner, for instance.
After several cleanings, however, the filter must be replaced.
Replacement filters are available from Biddle.
