5 SERVICE AND PROGRAMMING
The service panel has a different function in each mode. Installation mode (see chapter 5.1) ,
operating mode
(see chapter 5.2) and service mode (see chapter 5.3) are discussed in the
following paragraphs.
Faults may occur if the incorrect settings are used.
ᏘWhen you insert the service key, the power supply to the machine is
switched on.
➭Functions of the buttons
The 0button on the service panel opens the menu, closes the menu item
and saves the settings. The pin code “123” must be entered within 3
seconds after the 0 .
The beverage button of your choice or button 4on the service panel
enables you to scroll through the menus from top to bottom and increase
the values.
The beverage button of your choice or button 5on the service panel
enables you to scroll through the menus from top to bottom and decrease
the values.
To scroll through the menus and increase or decrease the values, press
the buttons to make small changes or press and hold to change the
values quickly.
5.1 Installing the machine
The machine can be switched on or off using the door or the service key.
☞To connect the machine, refer to the user manual.
The installation menu is meant to fill and empty the machine and to set a default setting of
variables and parameters. The menu can be entered by pressing the drink key 1 in the service
entry “installation”. By pressing the drink key 1 it is possible to go to the next entry.
