Maintenance and cleaning
Fig. 35-36
Ordinary maintenance - 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:
•
Pre-alarm: actives the notice about filters checking and cleaning (See:Operation and Use: Pre-alarm:“Checking filters”)
•
Alarm: actives the notice about clogged filters (See: Operation and Use: Alarm:“Filters replacing”)
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.
