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.

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.

1.2.2 "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.

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.

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.

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

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 operation produces a double quantity of the selected coffee (coffee + milk) product.

The TWIN function has to be activated by the Technical Customer Service.

5.5.4 Refill milk

The description of the procedure below applies to both the installed EF milk cooler and the external FC milk cooler.

! The installed EF milk cooler can option-

ally be fitted with a milk level monitoring system.

NOTE

•

The milk container for the installed EF milk cooler holds approx. six litres of milk.

• If the installed EF milk cooler is

fitted with milk level monitoring, then this will be activated when the milk supply in the milk container has dropped to about 1 litre or when the milk container is not in the installed EF milk cooler.

• When replenishing the milk

supply, always cover the lip seals of the milk cooler door of the installed EF milk cooler.

• The milk used to replenish

the milk container must be pre-cooled, i.e. it must not be any hotter than 1 - 5 °C. If hotter milk is used, the milk will overheat when "milky coffee" beverages are dispensed, insufficient froth will be created and it will not be possible to comply with the hygiene regulations.

• If the milk container is empty

when the machine comes to dispense beverages that include milk, the c5 coffee maker will dispense steam instead of milk.

CAUTION

• If the milk container is emp-

ty:

the addition of steam instead of milk to beverages can result in splashing of hot liquid, causing scalds.

• Replenish the milk supply

immediately.

6.1.1.2 Intervals between services

The c5 coffee maker is designed for a maximum of 100,000 cups per year.

The built-in safety mechanisms (relieve pressure valves) must be checked once a year to ensure that they are working properly. We recommend that this check is carried out during an (A) service of the whole system.

- "A" service

An "A" service of the whole system is required every 50,000 cups or no later than one year since the last "A" service. The following display message indicates the need for maintenance:

Contact Customer Support.

- "B" service

If the coffee maker has a milk system (EF or FC), than a "B" service of the milk system is required every 15.000 milk or coffee-plus-milk beverages (e.g. hot milk, cappuccino, latte macciato etc.). The following display messages indicate the need for maintenance:
