Espresso group [1000088]

The brewer is ¿ lled 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 À ows
via the splitter into the cup. After the coffee has been made, the
coffee pellet is ejected into the waste bin.
See Section 1.3 for the operation.

Ingredient and mixer system

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 measuring valve DV2. The instant product and the
water are mixed together by the mixer impeller driven by the mixer
motor running at 10,700 rpm. The drink À ows via the drink outlet
into the beaker.

Water vapour drain system

Most of the water vapour given off 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 water vapour getting into the
canister outlet and the ingredient becoming moist.

Door switches

There are two door switches on the inside of the right side wall.
Switch A is activated when the door is closed, and switches the
machine off when the door is opened.
Switch B is operated when the door lock is locked and switches
the hot water valve DV4 when the lock is opened.

Quick release coupling

In this machine various components are used that have quick
release couplings.
To remove the TeÀ on hose from this connection, the outer ring [A]
must be pushed in ¿ rst to release the hose [B].
This outer ring does not have to be pushed in when inserting the
hose.
Telfon® pressure hose
High quality TeÀ on pressure hose is used in this machine.
Never shorten this hose with side cutters. This will deform the
hose and when it is inserted into the quick release connection it
can damage the internal o-ring, resulting in leaks.
Always shorten a new hose using the special cutting tool (see the
illustration) or cut through it with a sharp knife without exerting too
much pressure on the hose.
