During the application of the discharge unit always make sure that mixing air flow will be
supplied first then the aerosol flow.

chambers can become contaminated. A high mixing air flow (depending on version, max. 18
or 36 m

Dismantling can only be effected by the manufacturer as an exact adjustment of the
components is essential when reassembling it.
