Continued efficient operation, reliability and a long serv-
ice life as well as safety, require inspections and mainte-
nance work to be regularly carried out by an expert
technician on an annual basis.
You must employ a qualified technician to complete
such work.
Caution! You must always ensure that units mounted
high up and units mounted in roof spaces can easily be
reached using suitable equipment.
a Caution!
We recommend making a maintenance agree-
ment. The operational reliability of the device
can be impaired, resulting in damage to proper-
ty or personal injury, if maintenance work is
not carried out.
The following must be checked:
– Soiling of the filters (cleaning or replacing the filters)
– Condensate discharge
– Function of the installed bypass unit
You as the owner or user may execute the following
maintenance work yourself:
– Clean and replace the filters in the domestic ventila-
tion unit.
– Clean and replace the filter in the bypass casing
(if installed).
– Clean the fresh air or exhaust air valves in the living
space.
– Reset the time interval for filter replacement in ac-
cordance with section 4.6 "Settings from the basic
display" Caution: Always ensure suitable access equip-
ment is used to gain access to eqipment installed at
high levels or in a loft space.
Caution!
a
Always ensure that the facilities installed high-
er or in the loft must be well accessible, if re-
quired, a suitable equipment must be used.
It depends on the contamination levels how often the fil-
ters must be cleaned or replaced. We recommend to
regularly check the filters during the initial operational
period and asses the need to clean them e.g. every
three months. If you then feel that the filters are only
slightly contaminated or dirty, you may extend the in-
terval.
h Note
Replace the filters at least once a year or after
maximum 2000 operating hours.
You can clean the filters with a vacuum cleaner. If this is
not enough, the filters must be replaced. Cleaning the
filters with water or other liquids is expressly prohibited.
Dispose the used filters with the domestic waste.
