Instant drinks
These drinks are prepared by continuously mixing the instant ingredient (powder) with hot water and
then mixing various mixed ingredients in accordance with the drinks recipe, which is set using the vending
machine’s service menu.
 Tomakethedrinkthewaterispumpedintotheoatchamber,fromwhereitgoesintotheboiler,untilit
islled.Theboilerheatsthewaterandmaintainsitatthetemperaturelevelsetinthevendingmachine’s
congurations.
The required quantity of the ingredient is poured out of the container into the mixer. The quantity of the
ingredient is set in accordance with the selected drinks recipe.
Opening one of the valves of the boiler the hot water is supplied to the required mixer, which is located
near the container with the required ingredient.
 Whenthewaterowsintothemixer,theingredientissolvedintotheamountofwatersetintherecipe.

Coffee bean drinks
Coffee beans go from the coffee bean container into the coffee grinder, where they are ground and fed into
thedosingapparatus(ifthedosingapparatuswillnotbelledwithin10secondsthevendingmachinewillau
-
tomatically block the dispensing of ground coffee drinks).
The dosing apparatus activates, feeds the ground coffee into the espresso group, after which the espresso
group closes and the coffee is pressed.
After this hot water release valve is opened towards the espresso group, the internal pump turns ON and
hot water from the boiler reaches the espresso group.
 Thewaterowsthroughthepressedcoffeetabandowsoutintothecup.
 Afterthesetamountofwaterhasownthroughtheespressogroup,theowstopsandtheusedcoffeeis
disposed of into the waste container.
Adding the foamed milk into drinks (FRESH MILK option)
Milk is taken from the milk storage container by the milk supply tube, mixed with air and supplied to the
cappuccinatore. Steam is also supplied from the steam boiler to the cappuccinatore for foaming milk.
To avoid problems associated with milk dispensing locate the milk container level with the vending ma-
chine and make sure that the milk supply tube lies on the bottom of the container and has no kinks.
 ToadjustthemilkowratefromthecontainertheHofmannclamp(seeg.4.2pos.8)isused,whichis

bytheclampscrew(theowrateisloweredwhenthescrewistightened,wherebythemilkfoambecomes
hotter and “airy” and vice versa).
