AIR FILTER
It is very important for the air treatment coil to be able to offer
maximum thermal exchange. Therefore, the unit must always
operate with the filters installed and clean.
Cleaning and replacement of filters are very important in terms
of health and hygiene.
The operating with clogged filters leads to a reduction of the
air flow, leading to malfunctions and unit shutdowns.
How often the filters need to be checked depends on the
quality of outdoor air, unit operating hours, dust and number
of persons in the rooms.
Approximately, cleaning should ideally take place between
weekly and monthly. It is advisable to start with frequent
checks, and to adjust the frequency based on how much dirt
is discovered.
Old filters must be disposed of, according to the law in force .
The filter is replaced after 2500 hours of operation with
the appearance of the alarm C3.

Filter extraction
Cleaning of the aeraulic system is to be carried out by
a specialised technician trained in aeraulic hygiene air
processing (in compliance with technical regulations
and national/local regulations in force).
The aeraulic system must be checked regularly to
verify the state of conduits.
If there are any dirt deposits, contact a specialised
technician and have it cleaned.
Cleaning is performed with the aid of suitable
instruments (wheel brushes mounted on a flexible
cable, vacuum cleaners, etc.), on supply and return
conduits, distribution boxes, grilles and aeration inlets/
outlets.
Conduits subject to dirt build-up are those that extract
air from the room, while inlet conduits are less subject
to clogging as the air is filtered; if an electrostatic filter
is mounted, filtration improves and the air introduced
into the room will be cleaner, thus resulting in cleaner
conduits within Elfofresch-Evo
