10.3 Component descriptions
10.3.1 Fans
The fans (pos. 3 and 8 figure 10) have external rotor motors of EC type which can be steplessly controlled
individually 20–100%. The motor bearings are life time lubricated and maintenance free. It is possible to
remove the fans for cleaning, see “User Manual” for more information.
10.3.2 Filters
The factory installed filters are of filter quality F7 for the supply air and G3 for the extract air filter. The filters
need to be replaced when polluted. New sets of filters can be acquired from your installer or wholesaler.
Filter quality G3 can be installed for supply air filtering.
The filter type is labelled on the top of the filter
Note:
If type G3 filters are used instead of F7 , the system curve for Supply Fan (SF) must be changed:
For G3 type filter: 11–20, for F7 type filter: 1–10. See chapter 7.3

10.3.3 Heat exchanger
SAVE VTR 200/B is equipped with a highly efficient, rotating heat exchanger. Required supply air
temperature is therefore normally maintained without adding additional heat.
The heat exchanger is removable for cleaning and maintenance, see “User Manual” for more information.
10.3.4 Print card
The main print card (pos. 6 figure 10) controls the functions and set temperatures of the unit. It is possible
to connect external accessories to terminals in the print card. See wiring diagram for more information.
