Commissioning
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 in relation to the rotary knob positioning. As per the
system design rules, the nominal ventilation must equal the total outdoor air volume flow. This nominal air volume
flow must correspond to a rotary knob position according to the illustration of the control unit.

Adjusting the valves
At the start of volume flow measurement, make sure that the supply air and extract air valves are
open as wide as possible.
•
Set the fans to the nominal air volume flow
•
Adjust the valve orifices, throttle valves or throttle foam inserts
•
Measure the volume flows at the outlets using a volume flow hood and flow meter (see air volume protocol)
•
Readjust the valves
•
Lock the valves, shutters and throttles in their adjusted positions
•
Record the set air volumes and all other settings in the documentation intended for this purpose
