11 Maintenance and cleaning
Make sure that the product is disconnected from the mains before starting
any operations.
11.1 Filters
Recommended maintenance timetable: In general the level of air pollution
depends on the geographical installation area, and therefore filter duration
is variable. With these considerations in mind, the maintenance times for
filters can however be set as follows:
• Filter inspection: every 50/60 days
• Filter replacement: after 3,9 or 12 months (depending on which was
set during installation by the installer). A pre-alarm signal, which warns
the user that filter replacement is necessary, will appear on the display.
Filters must be replaced within 2 months from this signal. The saturated
filter alarm will be activated at the end of this time. The counter will also
be reset when an error is reset (described in the paragraph on "Alarm
menu display").
Note well: Failure to clean or replace filters causes serious problems for
system efficiency, including:
• increased pressure losses in the air circulation system and reduced airflow;
• Consequent decrease in machine yield and worsening of comfort in the environment
Note well: Saturated filters are the most common cause of device blocking.

11.3 Heat exchanger
Checking and any cleaning of the exchanger must be carried out by professionally qualified personnel, preferably every 3
years. For cleaning, use a vacuum cleaner; for the H models the enthalpy exchanger can be cleaned using lukewarm water,
not at high pressure, and a detergent; rinse well after washing.
