Disposal notes
• Keep packaging materials away from children - polythene
sheets and bags can cause suffocation!
• Please return the packaging to an official collection point.
Your old appliance: This contains some reusable materials
and should be disposed of properly - not simply with unsorted
household refuse.
• Discarded appliances should be disabled: Remove the
plug, cut through the connection cable and render the
catch unusable so that children cannot become trapped
inside.
• Ensure that the refrigerant circuit is not damaged when
the appliance that is no longer needed is taken away
for disposal.
• Details of the refrigerant can be found on the type plate.
• Appliances which are no longer needed must be disposed of in a
professional and appropriate way, in accordance with the current
local regulations and laws.

Range of appliance use
The interior, which is free from sources of ignition, is used for
storing ammable substances in open or closed containers and
is therefore classied as a Zone 2 hazardous area.
The appliance is not suitable for use in explosion-hazard areas.
For the storage of valuable or temperature-sensitive substances or
products the use of an independent, constantly monitoring alarm
system is necessary.
This alarm system must be designed so that each alarm status
is detected immediately by an authorised person who can then
take appropriate action.
Position the temperature sensor for this system in the upper part
of the interior container (see Opening for external temperature
sensor).
