3.2.1 Dosing unit
Fragrance dosing is performed using a hose pump, which can also reliably convey
the smallest dosing quantities, even when air bubbles are trapped in the suction
line. The rotating rollers press the dosing hose against the wall, which pushes the
liquid in the hose out from the rollers while simultaneously feeding behind it. It is
exceptionally reliable and very easy to operate.
Fragrance concentrations may be exceptionally aggressive. The dosing hose used
is resistant to most commercially-available concentrates.
ATTENTION!
The composition of fragrances varies. This may reduce the service life of the hose. The
fragrance pump must therefore be checked regularly in accordance with the
maintenance schedule, or rather each time the fragrance is refilled.
3.2.2 Control unit
The operating parameters at the rotary potentiometer can be set at the control unit. The control board is
installed in a splashproof casing.
