Espresso group (reversed) [1004572]
Espresso group XL (reversed) [1004798]
The brewer is filled with ground coffee from the coffee grinder.
Then the coffee is compacted, the pump starts and pumps hot
water at a pressure of 10 bar through the coffee. The drink flows
via the splitter into the cup. After the coffee has been made, the
coffee pellet is ejected into the waste bin.

The 230-Vac motor in the drive unit drives the espresso unit.
The drive unit contains two microswitches that check the position
of the espresso group.

Instant group
Each of the ingredient canisters is driven by a motor running at
130 rpm. The instant product (ingredient) is pushed out of the
canister by a worm screw and falls via the dispensing nozzle into
the mixer unit. At the same time, hot water is measured into the
mixer unit by the measuring valve DV2. The instant product and
the water are mixed together by the mixer impeller driven by the
mixer motor running at 16,500 rpm. The drink flows via the drink
outlet into the beaker.
See Section
3.6 Instant group
for operation.
Ventilation mixer group
Most of the water vapour released during the mixing is collected
by the vapour drain ring and extracted via the extraction tray by
the fan. The instant residue is collected by the extraction tray. The
extraction tray can be easily removed (for cleaning) by dismantling
the mixer unit. This largely prevents the water vapour from getting
into the canister outlet and the ingredient from becoming moist.
