1.2 Mode of operation
1.2.1 c5 coffee maker
The c5 coffee maker is a fully automatic
coffee making machine which, in the basic
version, can dispense pre-programmed
coffee products through a height-adjust-
able product outlet into the container. The
beverage required is selected via five bev-
erage selection buttons.
The beverage selection buttons employ a
click pushbutton design that provides both
tactile and visual feedback. Large, illumi-
nated product fields indicate the beverage
currently selected.
A filling chute enables pre-ground, decaf-
feinated varieties of coffee to be pro-
cessed.
The c5 coffee maker exhibits the latest
marks of conformity, indicating that it satis-
fies the necessary certification standards.
For hot milk processing with integrated, ful-
ly automatic cleaning, the c5 coffee maker
satisfies the HACCP hygiene require-
ments.
The patented, Automatic Coffeequality
System (ACS) quality monitoring system
continually monitors relevant parameters
such as fineness of grind, coffee powder
weighed-in quantity, infusion time and wa-
ter temperature.
The piston system is optimally controlled
via a Variable Pressure System (VPS).
The water supply can be directly connected
to the water mains or to a water can.
1.2.2 "Installed EF milk cooler"
option
The installed EF milk cooler consists of a
compressor cooling unit, a separate pump
system, a temperature regulator unit and a
6 litre capacity milk container.
The milk is automatically added to the rele-
vant coffee products. The milk cooler door
can be lockable.
1.2.3 "External FC milk cooler"
option
The external FC milk cooler consists of an
industry-standard refrigerator.
If the c5 coffee maker is fitted with an addi-
tional external FC milk cooler, the c5 coffee
maker will contain an extra pump system
for the automatic addition of milk into the
relevant coffee products.
1.2.4 "Draw hot water" option
It is possible to draw hot water in user-de-
fined quantities by pressing a button.
1.2.5 "Draw steam" option
Steam can be drawn from the steam tap,
and is continuously adjustable.

1.2.6 "cw cup warmer" option
The autonomous cw cup warmer has three
levels with built-in heating elements.
1.2.7 "Second coffee bean
grinder" option
The second coffee bean grinder option al-
lows a second variety of coffee to be used.
Without this option, the second bean hop-
per is locked.
1.2.8 "Raised bean hopper"
option
A higher been hopper (a unit) can be pla-
ced on top of the bean hopper(s) to increa-
se the coffee bean capacitiy.
1.2.9 "Bean hopper lockable"
option
Lockable versions of both the standard and
raised bean hoppers are available.
1.2.10 "Milk level monitoring"
option
Milk level monitoring is used in conjunction
with the installed EF milk cooler. It is cou-
pled to the c5 coffee maker control system.
Warnings on the LCD enable the user to
keep an eye on the level of milk while the
machine is in operation.
1.2.11 "Raised feet" option
To clean the area underneath the ma-
chines, all the machines can be fitted with
raised feet.
1.2.12 "Waste water container
level monitoring" option
If the c5 coffee maker is connected to fresh
water and waste water cans, it is pos-
sible to monitor the level of the waste water
can (see also section «5.2 Water connec-
tion, 5 - 4»). The level monitoring is coupled
to the control system. The control system
outputs level-specific information to the
LCD.
1.2.13 Shift function
The five beverage selection buttons are al-
located as standard at two levels with one
pre-programmed beverage per level in
each case.
The Shift function switches the beverage
selection buttons to the second level and
back again.
1.2.14 TWIN function
Normally, one pass of coffee grinding with
subsequent infusion operation produces a
single quantity of the selected coffee (cof-
fee + milk) product.
With the TWIN function, one pass of coffee
grinding with one subsequent infusion op-
eration produces a double quantity of the
selected coffee (coffee + milk) product.
The TWIN function has to be activated by
the Technical Customer Service.
