C.3.3 Function: Mixer Unit
●
For the delivery of certain beverages (e.g.
espresso, cappuccino, cocoa-containing
beverage, iced cappuccino or iced choco) a
mixer unit is required. (Fig.1)
●
Mixer units are installed on the right and
left delivery side.
●
The impeller (1) of the mixer unit mixes the
water-concentrate mixture in the combi-
trough. (Fig. 1)
●
The mixer unit starts with a certain delay
(mixer delay) after the dosing of the water-
concentrate mixture.
●
The mixer unit remains switched on for a
certain time period (mixer time).

●
Mixer time and mixer delay can be adjusted
via the service device for espresso,
cappuccino and iced cappuccino.
(See chap. 4)
●
When delivering larger beverage volumes,
the mixer motor (2) remains switched on for
the set or fixed time. Dosing is, however,
adapted in such a way that the beverage
does not overflow the combi-trough. (Fig.1)
●
When using two mixer units, the second
mixer motor (2) can only be switched on,
when the connecting current of the first
mixer motor decreased below a certain
value. (Fig. 1)
