Setting the temperature values
Whentheunitisswitchedon,thedisplaywillinitiallyshowbriey
thetype of oven and aversionnumber.It willthendisplaythe

hold it down until the display shows the new gure required
(25°Cinthisexample).Thenreleasethekey.Thedisplaywillshow
the new setting for5 secondsand will then displaythe actual,
currenttemperature.
Ifalowerworkingtemperatureisrequired,thesameprocedure

Detecting a power failure
Whentheunitisrstswitchedon,thedisplaywillash.Pressing

indicate that the temperature in the oven can no longer be held at
theworkingtemperature,ifthepowerisoffforanextendedperiod.
Thecontrolswillcontinuetooperatenormally,evenifthedisplay
isashing.Theashingmerelyindicatesthat theunithasbeen

appliances or stirring apparates. The total load on the sockets
must not exceed 4,5 amps.

Cleaning
Clean the appliance at least twice per year.
Before cleaning always switch off the appliance. Pull out the
mains plug or switch off or unscrew the fuse.

•Important! The compressor and other parts may
stillbehotfromoperation.
Do not use steam cleaners because of the risk
of injury and damage.
Defrosting
Whenoperatingataverycoldthermostatsetting,theinteriorrear

andcleantheappliance.
Do not use any mechanical devices or other
artificial aids for defrosting other than those
recommended by the manufacturer.
Shutting your appliance down

The permissible room temperature for storing the appliance
after decommissioning is between -10°C and +50°C.
Storing the appliance outside this temperature range can
damage the appliance and cause it to malfunction.
