\ The Model 2000s/i
Pouring a steaming hot latte or cappuccino starts with the push of a button. The
Acorto lModel 2000 grinds fresh whole beans, brews the espresso, steams and froths
fresh miilk and delivers a perfect freshly brewed espresso beverage in less than 60
seconds,,
ln 1990, Acorto introduced the first fully automated espresso machine in Seattle,
Washintr5ton. The innovative machine earned Acorto several patents and broke new
ground by incorporating the grinding and brewing of fresh espresso, the steaming and
frothing of milk, and the 'oon board" refrigeration of milk, all in one machine.
Acorto super-automatic espresso machines are used in a wide variety of locations
ranging from corporate cafeterias, universities, hospitals; to casual dining and fine
dining restaurants; to convenience stores, hotels, supermarkets; to cruise ships, ski
resorts and airports.
Because the Acorto 2000s/i is completely automatic, computer-controlled and easy to
clean, mLinimal training is needed to run and maintain the machine. Our customers
are able to offer freshly brewed, premium quality espresso drinks around the clock.
The Gomponents
Touch Pad
z-1 The touoh pad provides a user-friendly interface for selecting and pouring a beverage.
CPU
The Central Processing Unit (CPU) acts as the "brain" of the Model 2000 and
controls all functions within the machine.
Electrical Encosure
The elec;trical enclosure houses the CPU, AC Board, and DC Board
Bean Hoppers
Each bean hoppers holds 2 % lbs offresh beans.
Water ltump
The waller pump increases the water pressure to 140psi during the extracting of
espresso.
Hot Warter Tank
The hot water tank elements heat the water used to brew espresso. Additionally, the
tank is aLttached to the brew group, so heat from the tank dissipates to heat the brew
group assembly.
Acorto 2000s/i Technical Support 2-3

Section 2: Overview 3o2o-oo2A
Brew Group
The brew group assembly precisely brews espresso, cup after cup. After fresh
espresso beans are groundinto the biew chamber, hot water is forced into th,e top of '\-"
the brew group, through the espresso grounds, and out the bottom of the chaLrnber to
the product outlet.
The brew group automatically pushes the used coffee oopuck" out of the chamber and
discards it into the Dress Bin.
Steam Tank
The steam tank provides steam for the automatic frothing of milk and optional steam
wand.
Refrigeration Unit
The on-board refrigeration unit holds two 1-gallon milk containers.
Grounds Bin
Located inside the left hand door, the Grounds bin catches the used ground coffee
pucks. The Grounds Bin holds approximately 40-50 coffee pucks, depenLding on
beverage size.
Drink Dispensing
The product outlet dispenses freshly brewed espresso while the patented milk valve
froths the milk. Both steaming hot milk and freshly brewed espresso are poured into
the waiting cup simultaneously.
