Fan unit ELS EC..
Commissioning without a filter is not permitted, as otherwise the unit and entire duct system will be contamina-
ted. The functionality of the fire damper may be affected by contamination. This can be prevented through regular
cleaning. Non-observance will result in a loss of warranty.
Special installation situations – plaster compensation
– casing too deep:
If the casing has been fitted too deep into the wall, the facade can be fixed with longer plastic screws (suitable plastic
screws are provided for each facade, scope of delivery: per 2 pcs, 25 mm and 40 mm).
6.3 Installation of presence sensor ELS EC.. P types
Detection angle horizontal approx. 100°, vertical approx. 80° (see Fig. 21, range information see section 7.3).
After the installation of the fan unit in the flush-mounted/surface-mounted casing, the sensor hanging from the cable
must be clipped in the provided opening on the rear of the facade frame (see Fig. 15/16). The correct position of the
sensor is ensured by a guide. Before mounting the facade frame, the sensor cable must be stored carefully (do not
clamp or mechanically load the cable).
Subsequently mount and screw the facade frame into place.
- Do not allow facade frame with mounted sensor to hang freely from the sensor cable, as otherwise the sensor
and control unit could be damaged.
- The sensor contains a very sensitive electronic component and it must not be opened or damaged in any
case.
