Barista can produce a drink called Latte Macchiato, composed by
milk and coffee and served in the cup in differently coloured bands,
typically milk, coffee and milk;
to get this special drink, refer to a specific package of instructions,
every step of which is called “LM dispensing cycle”; please keep in
mind some general principles to achieve this special drink quality:
- the first milk dispensing cycle shall not be too much mixed;
- the second milk dispensing cycle should occur after 10/15
seconds; mixing shall be extended and performed at the
maximum rotation speed of the impeller;
- the espresso coffee should be dispensed at least 15/20
seconds after the second milk dispensing cycle in the cup;
the data supplied by the table provide for a “latte macchiato”
dispensing cycle and they can be adapted to achieve dispensing
cycles more suitable for the users’ wishes;

to extract the slide including the fundamental components of the
vending machine, just remove the three screws A and separate the
two electric connectors B after having removed the coffee unit (see
13.05.) and the connectors of the temperature probes (see
05.38.a. and c.); now, you can extract the slide from the machine
cabinet;
after having extracted the slide of hydraulic components from the
cabinet, some “internal” parts can be easily inspected and
accessed; e.g. if the machine is disassembled this way, you can
easily set up the right phase of the coffee unit, which shall be
exactly in the position of the picture during the brewing phase;
the central articulation of the connecting rod shall be “moved
backwards” by some degrees compared to the ideal line joining the
axis of rotation of the unit and the upper end of the connecting
rod;
to achieve this result:
- loosen the socket head screw A;
- adjust the switch position by rotating the support as well as by
anticipating or postponing the cam trip on the switch lever;
- screw the socket head screw again;

the Rhea Barista vending machine is a machine explicitly designed
for being easily used by all users since no specific competence is
required in preparing drinks;
the function consists in dispensing drinks by mixing food products
and water at a proper temperature; the correct operation of the
vending machine occurs in closed rooms in normal environmental
conditions and at a room temperature between 5°and 35°C, the
relative humidity below 80%;
use only specific ingredients for vending machines;
dispense by briefly pressing a key of the selection keyboard
(see 05.02.); make sure that the cup has been properly positioned
at the dispensing station, if necessary by using the flap support for
caps (see 03.08.);
after having closed the door, press the buttons to dispense; keys
will assume various functions in the programming mode (see 09.)
and enable the user to modify the machine parameters; keys are
numbered progressively from the left: 1, 2, …;
the front cover side just above the selection pushbutton panel
accommodates the pocket where to insert the stripe specifying the
names of the selections you can obtain;
the display messages inform users and operators about the
operation state of the vending machine;
the front panel of the door is lighted by a neon tube arranged in a
door compartment; the panel is orange in the espresso machine
and light blue in the instant machine;
a light indicator is blinking (colours as above) during the dispensing
cycle of drinks;
the Barista vending machine has got a fixed drink dispenser on the
cup support surface;
the door is closed by means of a lock; the key is mapped and
numbered for identification;
it collects all residual drops from the dispenser and, if necessary,
the waste water in excess from the boiler; it is slided at the bottom
of the machine case, in the front, and it is composed by a covering
drawer and a grilled cover that can be washed by running water;
an electric contact is intended to control the filling level (see 10.01.
and 13.01.); the floater is raised if the content is in excess;
a three-terminal socket is arranged at the back of the case for the
connection of the mains cable;
to power on and off the machine;
installed on the mains power supply (see 03.11.);
from where to let the silicone tube from the boiler come out for
emptying, in I machines;
the water inlet solenoid valve on R machines only has got an anti-
flood safety device intended to stop the water inlet in case of
failures; to its electrical pins can be connected in parallel an any
submersible pump (see 03.03.);

to power off the machine when the door is open;
attention
some parts remain anyway network-connected
act extremely carefully
use the service key to supply the vending machine if it is necessary
to activate the machine when the door is open; the service key is
in a support on the left wall inside the vending machine;
the button giving access to the programming mode of the machine
is arranged inside the door at the bottom of the cover (PROG);
the connection for insertion of the flash key is made available on
the cover, on the right side;
it contains coffee beans, it is protected by a cover; an orange
closing baffle enables the operator to lift it on safe conditions;
the grinder grinds the coffee beans in the hopper to pour them into
the coffee unit underneath; the grinding degree can be adjusted by
means of the index inside the semicircular sector;
after having received and compressed the ground dose, the coffee
unit will brew it with the water coming from the pump; the used
dose is conveyed to the grounds container (see 05.23.); it is
fastened by means of a lever;
the coffee brewer motor will rotate some parts of the coffee brewer
to compress ground coffee for brewing; rotation is controlled by a
switch driven by a cam that will inform the CPU on the position of
the brewer;
a switch makes sure that the coffee unit is properly installed to
prevent it from dispensing espresso in case of shortage;
it collects over sixty ground doses in E machines after having used
them in the coffee brewer; a software option (see 09.01.n.) will
show a warning message as soon as the tray is full;
instant product canisters dispense their content in the underlying
mixing bowls; an internal worm screw driven by the product motor
will push the instant product to the product slide; they can be
equipped with a wheel and a stirrer for constant dispensing; the
outlet, the dimension of which can be either standard or smaller,
has got a closing baffle;
the coffee bean canister (hopper) has a closing blade for insertion
before lifting it and a metal tongue that enables the machine to
dispense espresso drinks after having inserted it into its seat (see
05.35);
to protect the products, canisters are closed by a cover; the
versions not connected with the water mains are complete with a
water tank in the place of a product canister and it can be filled
through a cover hatch of the vending machine (see 05.29.);
they are intended to rotate the worm screws inside instant product
canisters to pour the product quantity necessary for selection in the
mixing bowls;
the mixing bowls of the mixers will accommodate the instant
products you have poured to mix them with water; the fan of mixer
motors will act at the bottom and the drink outflow to the
dispenser occurs by means of a silicone tube; mixing bowls and
outlet tubes can be washed with lukewarm running water;

the motors of mixers help to mix instant products with water by
means of the rotation of the fan mounted on their axis; the
rotation speed can be adjusted (see 09.01.a.) to the features of the
various products;
a support on the cup station accommodates the dispensers coming
from the mixer bowls; it can be locked in its open position for a
better access to the machine;
only in A machines, on the cover of the vending machine, a door
enables the operator to access the water tank inside for filling
purposes; the tank is complete with a floater signalling by means
of a red stripe that it has been filled in excess;
an aspirator will eject suspended product residuals from the
vending machine; the aspirator is connected with a drawer to
intercept the residual impalpable powder coming from selections;
the action time of the aspirator is programmable by means of a
software parameter (see 13.18. and 09.01.f.); aspirated air is
ejected through the slots of the rear panel;
to aspirate the air from the internal environment of the machine to
avoid any condensate;
in E machines, it accumulates water for conveyance to the heat
exchanger; the level is controlled by a switch operated by a floater
and, if higher than established, it will flow back to the safety device
of the inlet solenoid valve, thus preventing further water from
flowing in;
for the espresso version only, it supplies the CPU with the water
quantity flowing through the coffee unit to determine its volume
and dispense the espresso you wish;
the water quantity of instant selections is established by the time
set in the “water N” parameter only (see 09.01.a.);
in E machines, a vibration pump with by pass conveys water to the
heat exchanger supplying the espresso hydraulic circuit;
this switch is pressed when the coffee hopper is installed in the
right position; otherwise, no drink including espresso coffee will be
dispensed;

it heats and accumulates water for the circuit of instant drinks;
active elements (heating element, heat protections, temperature
sensor, pumps) are all secured to the cover;
pumps with turbines immersed in the boiler water; water is
conveyed in tubes feeding mixing bowls; (attention to the
polarisation of motors; see 03.16.); the water quantity of instant
selections is established by the time set in the “water N” parameter
(see 09.01.a.);
