3. Filter Replacement
The clogging of the filters is monitored automatically
by the M-WRG-S ventilation unit. In case the filters
need to be replaced, an acoustic signal will inform 2–3
weeks prior to the replacement. The intervals of the
acoustic signal will shorten over the time period when
the filter replacement is necessary. You must change
the filters if the acoustic signal sounds for a period of
one second per hour.
3.1 Filter selection
•
For the M-WRG-S ventilation unit you have
multiple filter options. For normal operation the
Standard Filter (G4) is sufficient.
•
For persons suffering from allergies, you may
choose to install the Allergy Filter (F7). (only
needed for supply air )
•
In order to prevent unpleasant odours and
emissions or even harmful gases (gasoline,
nitrogen oxides, etc.) from entering your
home, you may choose to install the Activated
Carbon Filter (F6). (only needed for supply air)

Only use original filters from Meltem!
Otherwise Meltem cannot guarantee a smooth
operation and may not be held liable for any
malfunctions.
Replacement filters can be ordered at your local
