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-adjustable product outlet into the container. The beverage required is selected via five beverage selection buttons.

The beverage selection buttons employ a click pushbutton design that provides both tactile and visual feedback. Large, illuminated product fields indicate the beverage currently selected.

A filling chute enables pre-ground, decaffeinated varieties of coffee to be processed.

The c5 coffee maker exhibits the latest marks of conformity, indicating that it satisfies the necessary certification standards.

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 relevant 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 additional 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.

For hot milk processing with integrated, fully automatic cleaning, the c5 coffee maker satisfies the HACCP hygiene requirements.

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 water 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.

1.2.4 "Draw hot water" option

It is possible to draw hot water in user-defined quantities by pressing a button.

1.2.5 "Draw steam" option

Steam can be drawn from the steam tap, and is continuously adjustable.

OI c5 eng V9 / 18.08.2006 1-3 © Cafina / Melitta

DESCRIPTION

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 allows a second variety of coffee to be used. Without this option, the second bean hopper is locked.

1.2.8 "Raised bean hopper" option

A higher been hopper (a unit) can be placed on top of the bean hopper(s) to increase the coffee bean capacitiy.

1.2.11 "Raised feet" option

To clean the area underneath the machines, 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 possible to monitor the level of the waste water can (see also section «5.2 Water connection, 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

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 coupled 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.

The five beverage selection buttons are allocated 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 (coffee + 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.

DESCRIPTION

1.2.15 Key cards

Key cards are needed to access the functions of the c5 coffee maker.

Functions such as switch on/switch off, counter readout or programming can only be used if one has the relevant authorised key card.

1.2.15.1 "user" key card

The "user" key card is the card of the person who operates the c5 coffee maker. This card can be configured as a multi-user card for up to six c5 coffee makers.

1.2.15.2 "manager" key card

The "manager" key card is the card of the person (manager), who uses this card to gain access to the higher-level functions. This card can be configured as a multi-user card for up to six c5 coffee makers.

1.2.15.3 "memory" key card

The "memory" key card contains all the system data for the c5 coffee maker, as it was configured at the time of (first) installation by the service technician.

The "memory" key card enables the coffee maker to be reset following an emergency.

1.2.15.4 "free vend" key card

The "free vend" key card enables beverages to be dispensed at no charge, using external billing modules.

1.2.15.5 "vip" key card

The "vip" key card enables the self-service mode to be enabled or disabled without having to delve into the programming of the c5 coffee maker.

1.2.15.6 "external" key card
