Maintenance/Cleaning
Filters
Recommended maintenance intervals: because levels of
air pollution depend typically on geographical location
and are variable, the life of the filters will be similarly
variable. With this general consideration in mind, check
following alarms for filter maintenance (see also "Use"):
- Pre-alarm: actives the notice about filters checking and
cleaning
- Alarm: actives the notice about clogged filters
Resetting filters timer (See: Operation and Use: "User
operation menu", "Resetting filters timer") is resetted also
the counter.
NOTE Failure to clean or replace filters can seriously
affect system efficiency, causing:
- increased pressure losses in the air circulation system
and reduced airflow;
- drop in system performance and comfort levels caused
by pressure losses.
To access the filters, follow the instructions below:
• disconnect the appliance from the mains.
• remove the filters from the appliance (figs. 25,26,27)
