Avoid therefore:

obstacles to the airflow
 exchange difficulties
 leaves or other foreign bodies that can obstruct the exchange
batteries

winds that hinder or favour the airflow

heat or pollution sources close to the unit (chimneys,
extractors etc)
 stratification (cold air that stagnates at the bottom)

recirculation (expelled air that is sucked in again)

positioning below the level of the threshold, close to very high
walls, attics or in angles that could give rise to stratification
or recirculation phenomenons.
Ignoring the previous indications could:

energy efficiency decrease

alarm lockout due to HIGH PRESSURE (in summer) or LOW
PRESSURE (in winter)
CBK, CCK, CCKP configurations only
Avoid the accumulations of snow and ice in front of the exhaust
air outlet.
Pressure relief valve gas side
The installer is responsible for evaluating the opportunity of
installing drain pipes in compliance with the local regulations in
force (EN 378).
If ducted, the valves must be sized according to EN13136
.
Only if electronic filter is present
The most common contaminants for which the filter is designed,
are:
 air pollution by PM10, PM 2,5 and PM1
Contaminants that can be filtered:
 dry smokes

powder (up to 0,3 microns)
 smoke electrostatically charged
Contaminants that can NOT be filtered:

water vapors also in low concentration

oil vapors

large amounts of dust

metal shavings,iron filing dusts and waste generally

Gas
Absolutely to avoid:

metal dusts also fine

fumes produced by combustion of organic and not materials
(wood, coal, gasoline, etc.)
only CBK, CCK, CCKP
Avoid snow accumulating
