Note
It is advisable to check the LED on the ventilation unit regularly.
ä Attention
!
If a dirty filter is detected, the resident also receives a signal
because the operation suddenly seems to work the other way
around: if you press the Low mode button on the remote control,
the ventilation unit goes to High mode and if you press High
mode, the unit goes to Low mode. Check the LED on the
ventilation unit. If it flashes, the filter needs to be cleaned or
replaced.
2.8.4. Filters
The HRU ECO 350 has two filters, one for each air flow. Both
filters are placed in the ventilation unit in such a way that they
protect the exchanger from contamination. In addition, the filter in
the air supply also protects the user against dust and other
contaminants in the sucked in outside air.
There are different types of filters:
●
Filter G3 (Filter ISO Coarse
³45%
).
This filter is supplied as standard with the appliance and is very
suitable as a 'building material filter' in the first period after
delivery of the new home. After about three months the filter has
to be replaced by a G4 or F7 filter.
●
Filter G4 (Filter ISO Coarse ISO 65%.).
This coarse filter is mainly used to filter relatively large dust
particles from the air. This mainly protects the heat
exchanger against penetrating dirt.
●
Filter F7 (Filter ISO ePM2.5 70%).
In addition to the coarser dust particles, this fine filter also
stops finer dust particles (pollen). Especially people with
allergy complaints, who are sensitive to this, can benefit
from this.
Over time, the filters will become dirty, which will reduce the
capacity of the ventilation unit. It is therefore necessary that the
filters are cleaned according to the instructions and eventually
replaced.
2.8.4.1. Filter warning
The control of the ventilation unit keeps track of when the filters
need to be cleaned or replaced by means of a counter. If a dirty
filter is detected, the LED (

) on the ventilation unit flashes orange.

Warning!
