  Commissioning the FOCUS unit 

 

Readiness for operation 

The unit is ready for operation once all the requirements of the safety regulations and installation 
conditions have been met. In particular, this means ensuring that the ventilation tube material is clean 
and that all the ventilation technology components required to operate the system are present, 
properly installed and ready for operation.

 

Check all the safety-related components and carry out a function test.

 

 

Adjusting the air volume flow 

Once you have checked that the FOCUS unit is ready for operation, you can commission it as described below. Diagram 
1 shows the scale for the available air volume flow to enable rotary knob positioning. According to the plant design the 
total outside air volume flow is to be laid out as nominal ventilation. This nominal air volume flow should correspond to 
a rotary knob position of figure control panel.
