secured table, bench, cabinet or food and drink counter.
Cabinet Front

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

Cabinet Interior
10. A swivel open door provides access to the plastic product containers, each fitted with a
gear driven worm screw located in the base of each canister to dispense ingredients in
exact amounts.
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 three
canisters are removed and steam hoods of the mixing bowls are removed the extract chamber
can be removed for cleaning.
11. Located on the upper 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.
12. 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.
13. 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.
