can be connected to the water supply and power supply.
• Connect the appliance to an earthed wall socket.
• Position the appliance in such a way that no damage can be caused if it leaks.
• Do not tilt the appliance, always position and move the appliance upright.
• Connect an overflow pipe to the drainage tube.
• Water always remains in the heating system: for this reason the appliance must not
be placed in an area where the temperature can fall below freezing point.
• When installing the appliance, always observe the local rules and use approved
materials and parts.
• The Installation chapter must again be followed when repositioning the appliance.
• Connect the appliance to the cold water mains.
2.1.2 Use
• Inspect the appliance before using it and check it for damage.
• Never submerge or spray the appliance.
• Do not press the buttons with a sharp object.
• Protect the controls against dirt and grease.
• During use some parts will become very hot.
• Do not position the container on open fire, or hot plate.
• First disconnect the electric cable before transporting the container.
• It is advisable to take the plug out of the socket and close the water tap if the ap-
pliance is not going to be used for longer periods of time
2.1.3 Maintenance and troubleshooting

• Overdue maintenance to the heating system can result in high repair costs and an-
nulment of the guarantee.
• Do not leave the appliance unattended when maintenance is being performed.

• When descaling the appliance, it is advisable to wear safety glasses and protective
gloves.
• Wash your hands after descaling.
• Have all repairs carried out by a qualified technician.
• The plug must be taken out of the socket if the appliance has to be opened for
cleaning or repairs.
2.2 Safeguards
The appliance is fitted with the following safe guards
2.2.1 On/off switch
The on/off switch is used to switch the appliance on and off. Remember that the appliance
can still be live after being switched off! For this reason you should always remove the
plug from the socket to render the appliance voltage-free.
2.2.2 STOP button
The coffee making process can be interrupted at any point using the STOP button located
on the control panel.
2.2.3 Swivel arm and container detection
This appliance is equipped with a safety device through which it is only possible to start
the brewing process if the swivel arm and container are in the correct position. If the swiv-
el arm and/or container are moved out of position during the brewing process, the brewing
process is interrupted, a swivel arm and/or container symbol appears in the display and
there is a sound signal (2x short). Once the positioning fault has been resolved the brewing
process can be restored by pressing the START button.
2.2.4 Dry-boil protection
This appliance is equipped with a dry-boil protection. This protection triggers if the heat-
ing elements overheat owing to a fault. Once the fault has been resolved, the dry-boil pro-
tection can be reset at the outside of the appliance. The most common cause of the dry-
boil protection being triggered is not descaling the heating system in time.
2.2.5 Warning indication display
A technical fault is reported by displaying an error code in the display. The relevant prob-
lem can be localised and resolved with the help of this code. In this case see chapter 13-
Troubleshooting.

about the alternatives for recycling the materials. All plastic parts have been given stand-
ard codes. The parts of the appliance such as the printed circuit board and accompanying
parts form electrical and electronic waste. The metal body is made of stainless steel and
