5 INSTALLATION AND OPERATION
5.1 SAFETY INFORMATION
WARNING! Risk of electrocution!
The device must be installed by qualified professionals.
•Device may cause injuries due to improper installation!
•Before installation, check the data of the local power grid with the technical specifications of the
unit (see nameplate).
•Connect the device only if they match! Follow the safety instructions!
•The device may only be operated when connected to a properly installed single socket with protec-
tive contact. Don’t use any multiply sockets. A safety switch is mandatory when installing a unit.
•Do not pull the plug from the socket by the cable.
•The power cord must not come into contact with hot parts.
WARNING! Hot surface!
During operation, some parts of the device become very hot. To avoid burns, do not touch hot parts!
•Do not use this device if it is not working properly, is damaged or has been dropped.
•Do not use any accessories and spare parts which are not recommended by the manufacturer.
These could pose a hazard to the user or cause damage to the device and cause personal injury,
and also void the warranty.
•Do not lay the cable over carpets or other heat insulation. Do not cover the cable. Keep the cable
away from work areas and do not immerse in water.
•Do not move the device during operation and do not tip it over.
•Never heat food or liquids in sealed containers or bottles. This builds up a pressure which can
cause the container or bottle to explode.
•The multifunctional well must not be used as a storage area. Accidental activation or residual heat
can cause objects left there to melt or burn.
•Make sure that the cable does not come into contact with heat sources or sharp edges. Do not
hang the cable off the table or counter.

5.2 INSTALLATION AND ELECTRIC CONNECTION
5.2.1 INSTALLATION OF THE MULTIFUNCTIONAL WELL
•Put your device on a level and safe surface which stands the weight of the device.
•Prepare the cut-out of the table according to our installation drawings and check the cut-out.
•For Dekton (artificial stone) and stone plates please refer to the stone manufacturer’s references.
•Make sure the surface is free from dust and grease.
•Locate the multifunctional well in the middle of the cut-out.
•The multifunctional well should not protrude beyond the work surface.
•The built-in multifunctional wells must be professionally glued with a suitable adhesive in the cover
plate.
•Connect the controller and both cables to the circuit board according to the connection plan.
NOTE regarding the installation!
•The device has to be installed in vertical position.
•The multifunctional well has to left in vertical position at least 15 minutes before operation.
•The multifunctional wells can be built-in flush-mounted or sunk in every top plate (wood, granite,
corean or stainless steel).
•The supply and exhaust air must be ensured for all the built-in units. The ambient temperature of
30°C mustn’t exceed in operation (heat accumulation) because the cooling performance decreases
and the device might get damaged. Please note that warm air rises. Please use parts of the wide
range of built-in accessories like fans or tubes in adverse built-in situations. Referring to this, the
qualified professional can give you some advices.
•Built-in device: On-site supply and exhaust air must be taken into account when installing the
devices in base cabinets. The open cross-section for the supply air and exhaust air openings must
be at least 200 cm², and the air should be able to flow freely over the cooling unit.
•Built-in device: The supply air of the devices must not mix with its own exhaust air or the exhaust
air from other devices. The exhaust air from the devices must be discharged unhindered, no
exhaust air may accumulate near the devices.
•Built-in device: If devices are installed next to each other in a common substructure, then each de-
vice must have a separate supply air and the exhaust air from each device must be discharged un-
hindered. In the common substructure, no exhaust air must accumulate near the devices and the
exhaust air from the devices must not be routed through other devices. The supply air and exhaust
air from the devices must not mix.
ATTENTION!
The device must be installed by a qualified professional.

5.3 OPERATION
•Clean the device prior to use as described in chapter 6.2 Cleaning.
•Press the button to switch on the device.
•Do not place food directly on the surface. All foods should always be placed in appropriate con-
tainers on the surface of the multifunctional well. Use only suitable tableware. Do not use plastic
tableware.
•Do not use pots or pans with a bottom which has ridged edges or is unevenly enameled. This can
cause permanent scratches.

Noise during operation (only for compact system)
To keep the selected temperature constant when cooling, from time to time, the multifunctional well
switches the compressor of the cooling unit on. The sounds which occur are related to functionality. They
will reduce automatically as soon as the unit has reached operating temperature. The humming noise
comes from the compressor.
