7. MAINTENANCE / CARE
7.1 General
Maintenance of the unit for the end user is limited to the periodic cleaning of the filters and
the intake / exhaust air valves and grilles. Twice a year, the texts “FIL” followed by “tEr”
appear alternately on the display as a reminder to clean the filters. Cleaning of the valves /
grilles is recommended at the same time as the cleaning of the filters. The system must not
be operated without filters. Switch off the unit at the three-position switch or mains power
switch before changing the filters.
