7 Servicing and maintenance
To permanently ensure a hygienic heat recovery ventila-
tion system, it is particularly important to maintain and
service the system at regular intervals. For this reason, we
recommend signing a maintenance contract with a fitter for maintaining and cleaning the system. According to DIN
1946-6, the parts listed below should be inspected regu-
larly and replaced or cleaned if necessary.
Components Maintenance / inspection intervals
Air filter
Inspection of all air filters (also in the ventilation unit, in extract air valves, prefilters, such as
earth-air heat exchangers or preheaters if any) for contamination and replacement if necessary
every six months
Ventilation unit
Inspection and, if necessary, cleaning of the heat exchanger and/or fans
Inspection of condensate drain and siphon every 2 years
Air distribution
Inspection and cleaning, if necessary, of the ventilation ducts, manifolds and ventilation valves
every 2 years
We recommend inspecting the air filters after three
months of operation and replacing them according to the
degree of contamination. Orange flashing incl. an acoustic
signal of the fault report indicator on the internal control panel and indication of an error message in the profi-air
cockpit app will remind you of filter replacement after the set
interval has expired.
