Technical Information
INTRODUCTION
1. The Vitro X3 Beverage Machine dispenses hot beverages in response to a capacitive touch
screen drink selection. All beverages are dispensed in cup measurements. A liquid crystal
display provides status indications and operational information. All operations are
microprocessor controlled.
2. A cup is placed under the dispense head and the selection is made via a capacitive touch
screen. The drink is then dispensed in the required quantity. The machine does not accept
money as standard, but a feature such as this can be added.
3. The status of the machine may be monitored, and the configuration altered, by accessing a
program using the keypad and display. The program offers a menu of options; each
consisting of a number of sub-options which can be altered.
4. The Vitro X3 Beverage Machine has a feature, which heats the water in the boiler very
quickly, with one heater connected to the instant boiler and another to the espresso boiler,
from the same 230V~, 16A single-phase supply.

GENERAL DESCRIPTION
8. The Vitro X3 Beverage Machine is a table top unit which may be mounted on a secured
table, bench, cabinet or food and drink counter.
Cabinet Front
9. The cabinet front door has a large glass panel and located within this panel are 10
capacitive touch switches. On the rear of the door is the display for accessing product
information and machine settings with an internal keypad which provides access to the
Operator’s and Engineer’s Program and a USB port
10. The panel can, when unscrewed, be hinged to give access to the ZMCU control board,
button control board, ZMCU adaptor and capacitive touch PCB’s.
Cabinet Rear
11. The rear lower portion on the cabinet has six screws which if removed allow the espresso
boiler, solid state replay, pump and valves to be accessed by sliding the metalwork which
all of this is mounted onto out.
Cabinet Interior
12. A swivel open door provides access to the three plastic product containers, each fitted with
a gear driven worm screw located in the base of each canister to dispense ingredients in
exact amounts. Accessed through the lid of the machine is the forth bean hopper canister.
The ingredients are mixed with hot water in mixing bowls prior to the beverage being
poured from the dispense head.
A plastic agitator is located inside of the milk topping and chocolate canister to ensure free and
consistent flow of product. Additionally a whipper unit, located beneath the mixing bowls,
ensures that the product and water are correctly mixed.
The ingredient canisters must be removed for filling of the products and when all four canisters
are removed and steam hoods of the mixing bowls are removed the extract chamber can be
removed for cleaning.
13. Located on the rear of the machine on the back left hand panel is the machine on/off
switch, which controls the power to the MPU, power supply. Access to all other components
is either by removal of the lid assembly/boiler cover and motor shelf.
14. Further access to the inner components is achieved by removing the left-hand side panel
by unscrewing the location screw and then the panel will drop down clear of its keyhole
slots. Removing this panel gives access to all internal components.
15. The mains electricity supply cable enters the machine via a cable gland on the base panel
of the machine, where it terminates in a terminal block. The supply is then connected via
the terminal block, line filter to the on/off switch on the front of the machine.

WATER SYSTEM
16. The main water supply enters the machine via a double inlet valve, which is mounted in the
cabinet base panel. A length of tube then takes the water supply into the top of the water
boiler via an air break into a channel, which is directed, to the bottom of the heater tank for
the instant products.
The Espresso system water enters through the same double inlet valve mounted in the
base of the cabinet. The water then enters an internal water tank where it sits before being
pumped via an ULKA pump into the espresso boiler.
17. Instant hot water is dispensed from the boiler, via the appropriate solenoid operated valve,
to the mixing bowl. A length of tube directs any overflow from the boiler via overtemp safety
thermostats to the waste tray.
Espresso hot water is dispensed from the boiler, via the appropriate solenoid operated
valve, to the brewer group. A length of tube attached to the purge valve on the top of the
coffee valve directs any overflow into the water tray. The boiler is protected via overtemp
safety thermostats to the waste tray.
18. The cold water mains supply enters the machine at the back of the cabinet and connects
with a double solenoid operated inlet valve, which controls the flow of water to both the
instant and espresso boilers. The water is maintained at a constant level in response to
signals from a water level probe which is connected to the Controller Board for the instant
and a volumetric counter for the Espresso system.
19. The water is heated to the required temperature by a single heating element in the instant
boiler and a single element in the espresso boiler. The Controller Board ensures that the
temperature is maintained to a predetermined level by controlling the supply to the heater in
response to signals from the N.T.C. temperature sensor which forms part of the
level/temperature probe assembly in the Instant boiler and temperature sensor in the
Espresso boiler.
20. Hot water from the boiler is fed directly to the mixing bowls where it mixes with the
dispensed ingredient to produce the selected beverage. Solenoid operated valves
distribute the hot water to the selected mixing bowl, the amount of water being determined
by the program setting.
21. The temperature of the water is monitored by the Controller Board via a sensor inserted into
the tank, thus causing the supply to the heater to be removed when the water in the boiler
reaches its required temperature setting. If the temperature in the boiler increases causing
the water to boil over, the water will flow down the overflow pipe over the overtemp sensors
which will cut off the electrical supply to the heating elements. These sensors are mounted
on the cabinet rear and are re-settable.
Heater and Boosting
22. The instant heating control system employs an intelligent algorithm to obtain maximum
performance as follows:-
Boost operation takes place when the inlet valve opens following a selection being taken. The
heater control algorithm is instructed to turn on the SSR’s for the duration specified in the
variable CUP BOOST referred to Section 2 paragraph 24.
If the temperature is 50 more than the DESIRED TEMPERATURE, set in the CHANGE
SETTING MENU (see Section 2 paragraph 24) all boosting operations are disabled.
If the actual temperature is between 0 –35 less than the DESIRED TEMPERATURE one SSR
