Tab. 77: Setting the extraction capacity regulation

1. Close all detection elements (Pos. 1).

2. Switch on the product. (See also chapter Commissioning)

3. Now open the most distant central extraction elements fully so that

approx. 20% of the free cross-sectional area is reached. In this example,

A + B must be opened.

4. Open the control cabinet (Pos. 2) and, on potentiometer (Pos. 3), adjust

the extraction capacity so that it matches the required need or

regulations.

5. Further extraction elements can now be opened. The extraction

capacity control detects the falling negative pressure and automatically

regulates the air requirement so that the previously set extraction

capacity is guaranteed at the respective central extraction elements.

NOTE

It is not the potentiometer that is used to set the fan speed, but the

vacuum in the extraction pipe. Please note the following:

The filter cartridges become saturated over their life cycle, which means

that the extraction capacity decreases. The extraction power

compensates this automatically, but only until the maximum fan speed is

reached. Any further readjustment via the potentiometer is then

ineffective.

When the maximum fan speed is reached, the optimum extraction

capacity at the respective central extraction elements can no longer be

guaranteed. A filter change is required.
