Switching the appliance on and off

WSwitching on: Press the on/off button 3 so that the temperature display lights up/ﬂashes.

-When the appliance is switched on for the ﬁrst time and while it is still warm, the display will contain dashes until the temperature falls below 0°C.

-The lighting will light up when the door is open.

WSwitching off: Press the on/off button for approx. two seconds so that the temperature display goes out.

Setting the temperature

The appliance is pre-set for normal operation. We recom- mend a temperature of -18°C.

WTo reduce the temperature: Press the DOWN button 2.

WTo increase the temperature: Press the UP button 2.

- While you are entering the temperature, the set tempera- ture will ﬂash on the display.

-When you press the temperature setting buttons for the ﬁrst time, the most recent setting (known as the "refer- ence setting") is displayed.

-You can change the settings in increments of 1°C by brieﬂy pressing the buttons again. If the buttons are held down the temperature setting will change faster.

-The electronic controls will switch over automatically about 5 seconds after the last time you pressed the but- ton, and the actual temperature in the freezer (known as the "actual setting") will be displayed.

-The temperature can be set at between -14°C and -28°C. Whether you can obtain the lowest temperature depends on where the appliance is positioned (if it is located in an area with a high ambient temperature it will not reach the lowest temperature).

Temperature display

The highest temperature of the frozen food 1 is displayed

in normal operating mode.

The display will ﬂash:

- if you change the temperature or

- if the temperature rises by several degrees, indicating cold loss, e.g. if you place fresh, "warm" food in the freezer or if you remove or re-pack frozen food the temperature may rise for a short time due to warm air ﬂowing into the freezer. Once you have ﬁnished loading or re-packing, the electronics will automatically re-set the temperature to the most recent setting. Short-term rises in temperature will not affect the frozen food.

W If "F 1" to "F 5" appears in the display, the appliance has a fault. Consult the customer service department indicat-ing the fault number displayed as this will tell the techni-cian what kind of irregularity has occurred.

* Depending on model and options

Audible warning signal

The audible warning signal helps to protect frozen food and to save energy.

WThe audible warning device is switched off by pressing the audible warning button 5.

-It switches off automatically as soon as the temperature is low enough or the door is closed.

Audible door alarm

-This sounds when the door has been left open for longer than about 60 seconds. The sound switch-off function is active as long as the door is left open. The alarm auto- matically switches back to standby when the door is shut.

Audible/visual temperature alarm

-It always sounds if the freezer temperature is not low enough (dependent on the temperature setting).

-The temperature display ﬂashes at the same time. This can be caused by:

-warm, fresh food being placed in the freezer,

-too much warm air from the outside entering when re- arranging or removing frozen food.

The temperature display will continue to ﬂash until the cause of the alarm has been rectiﬁed. It will then stop ﬂashing and light up continually. The audible warning signal is now automatically reset.

Power failure/FrostControl display

If appears in the display, this means that the freezer tem- perature has risen too high during the last few hours or days due to a power failure.

WIf you press the audible warning on/off button 5 whilst

the display is reading , the highest temperature regis- tered during the power failure will be displayed.

- Check the quality of the food and its suitability for con- sumption in case it has become too warm or even de- frosted.

-The highest temperature will appear for approx. 1 minute. After that, the actual temperature in the freezer will re- appear. The display can be switched off by pressing the audible warning on/off button.

Once the power is re-instated, the appliance will continue to operate at the most recent temperature setting.

Additional functions

In set-up mode you can set the child-proof lock and adjust the brightness of the display*:

Activating set-up mode:

WPress SuperFrost button for approx. 5 secs - the Super- Frost button ﬂashes - the display shows c for child-proof lock.

Note: the value to be altered ﬂashes.

WSelect the required function by pressing the Up/Down button:

c = child-proof lock or h = brightness.

WNow select/acknowledge function by pressing SuperFrost button brieﬂy:

•For c = child-proof lock, press the Up/Down button to select c1 = child-proof lock on or c0 = child-proof lock off and acknowledge with the SuperFrost button. When the symbol 6 is lit, the child-proof lock is activated.

•For h = brightness, press Up/Down button to select h1= minimum to h5 = maximum bright- ness and acknowledge with the SuperFrost

button.

Exit set-up mode:

WTo exit the set-up mode, press the On/Off button; after 2 mins. the electronic system switches over automatically.
