Initial commissioning
Before you start commissioning:
Check that the grilles are correctly seated.
Remove protective film, if any.
Ensure that all grilles are clean and free from
residues and foreign matter.
Ensure that the devices have been correctly
fixed and connected to the ducting.
For commissioning see also VDI 6022, part 1 – 'Hy-
giene requirements for ventilation and air-condi-
tioning systems and units'.
Volume flow rate balancing
When several grilles are connected to just one
volume flow controller, it may be necessary to bal-
ance the volume flow rates.
