Maintenance / cleaning
Before commencing any servicing operation, make sure that the appliance is disconnected from the electrical power supply.
Dismantling and assembly are special maintenance operations and must be entrusted to professional technicians.
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, the following filter maintenance intervals are recommended:
Inspect filters: every 50/60 days;
filter replacement: after 6/24 months from the last replacement
(according to the settings made by the installer during
installation) the machine goes into "dirty filter prealarm". This
status is signalled by some slow blinks of the led. From this
point on the filters must be replaced within 2 months; at the end
of these 2 months the saturated filter alarm is enabled (the led
stays on) and the machine stops. When the error is reset (as
described in "View alarm menu" paragraph), the counter will
also be reset.
N.B. 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.
N.B. Clogged air filters are the most frequent cause of the
appliance locking up.
