Cleaning the filter casing
Personnel:
Properly trained person
Protective equipment:
Light respiratory protection
It is usually not possible to regularly clean and dis-
infect the ductwork between the second filter stage
and the filter casing, and neither is it required for
hygienic reasons. As a prerequisite, however, you
have to keep the ducts clean during installation.
It is then sufficient to clean and disinfect (wipe) the
filter casing and the diffuser face; this has to be
done for the first time just before the ventilation and
air conditioning system is switched on for the first
time.
The casing may be cleaned with a damp cloth.
Sticky dirt or contamination may be removed with a
commercial, non-aggressive cleaning agent.
Cleaning agents that contain chlorine must not be
used.
Once you have completed cleaning, disinfect the
filter casing and any connecting rooms.
