4. Filter replacement
The clogging of the filters is monitored automatically
by the M-WRG ventilation unit. In case the filters
need to be replaced, an acoustic signal will inform
you, 2–3 weeks prior to the replacement. The interval
of the acoustic signal will shorten over the time
interval when the filter replacement is necessary. You
must change the filters if the acoustic signal sounds
for an interval of one second per hour.
4.1 Filter selection
For the M-WRG 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 odors 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 made by Meltem!
Otherwise Meltem cannot guarantee a smooth
operation and will not be held liable for any
malfunctions.
