• For a small amount of fresh food approximately 2-5kg, press the SuperFrost button 6 hours earlier before loading the fresh food.
• For large amounts of fresh food of more than 5kg, press the SuperFrost button 24 hours earlier before loading the fresh food.

Note:
The SuperFrost function switches off automatically. Depending on the quantity of food placed in the freezer, this will normally between 48 and max. 72 hours. When you press the SuperFrost button, the compressor might not switch on for up to 8 minutes. This is due to the integrated rise-delay switch which is designed to increase the life span of the refrigeration unit.

To save energy, SuperFrost can be switched off before the 48 hours have elapsed by pressing the SuperFrost button again. Ensure that the temperature is at least -18°C.

You should not switch on the SuperFrost function:

• when placing frozen food in the freezer;
• when freezing up to approx. 2 kg fresh food daily.

Notes on freezing

• Always store identical food items together.
• Pack food that you are freezing yourself in quantities appropriate to your household. To ensure that the food freezes right through, the following quantities should not be exceeded per package: fruit, vegetables: up to 1 kg, meat: up to 2.5 kg.
• In order to achieve fast freezing, food should be in contact with the interior walls when it is placed in the freezer.
• Pack frozen food in standard freezer bags or reusable plastic, metal or aluminum containers.
• Do not allow fresh food which is to be frozen to come into contact with food already frozen. Always keep packs dry in order to avoid them sticking together.
• Always write the date and contents on the pack and do not exceed the stated storage time for the food.
• Do not freeze bottles and cans which contain carbonated drinks as they might burst.
• Only take out as much food as is immediately required for thawing. Use food that has been thawed in prepared meals as quickly as possible.

Frozen food can be thawed in the following ways:

• in a fan oven
• in a microwave oven
• at room temperature
• in the refrigerator

Equipment

Interior LED light
An LED lamp is fitted as a standard to illuminate the interior of the appliance. The interior light switches on automatically when the lid is opened and switches off again when it is closed.

Replacing the lamp
If the lamp is defective, it can be replaced taking into account the following points.

1. Pull out the plug or switch off the fuse.
2. Remove the cover panel in the direction of the arrow.

Only original LED lamps from the appliance manufacturer may be used. The lamp can be purchased from the customer service department or specialist dealers.

WARNING!
When using LED lamps made by other manufacturers, there is a risk of overheating or fire.

Basket CFf

• The stable baskets support the storage of frequently required frozen goods and enable ergonomic access.
• The top level of the basket is the maximum basket load limit.

Baskets CFd

• Thanks to the possibility of adjusting the handles, the baskets can be used for different applications:
• The baskets can be suspended in the frame of the freezer by their handles.
• The baskets can be placed on top of one another, by sitting the upper basket on the handles that are folded inwards. To do this, press the handle down, lift, and tilt it inwards.

Lock
The lock is only fitted for the CFD model. A similar lock can be installed to the CFf model as retrofitted.

The lock is equipped with a safety mechanism.

Locking the appliance

1. Press the button and keep it depressed.
2. Turn the key 90°.

Freezer tray
With the freezer tray, small frozen food items (berries, herbs, chopped vegetables) can be gently frozen. Spread the frozen items out on the freezer tray (pieces of fruit do not stick together and so keep their shape).

The freezer tray can either be suspended on the basket or can be slid into the interior container and used as a partition.

Cold-storage accumulators
In the event of a power failure, the cold-storage accumulator delays the temperature increase in the freezer compartment. When switching it on for the first time, insert the accumulator in direct contact with the interior container side walls and the interior container floor so that it freezes quickly.

• When the accumulator is completely frozen, position it at the top of the interior container.
• To do this, place the freezer tray containing the accumulator in one of the top baskets.
• If the freezer tray continues to be needed as a partition, place the accumulator in the basket directly on top of the frozen goods.

The accumulator is only provided in the CFD model. The additional accumulators can be purchased from the customer service department or specialist dealers.

StopFrost system

• This system reduces the formation of frost or ice so that the appliance needs defrosting less frequently.
• The formation of frost or ice depends on the operating and ambient conditions.

Important note
To ensure correct functioning, the opening of the Stop-Frost system at the back of the lid must not be closed.

Defrosting

After the appliance has been in operation for some time, a layer of frost or ice will form on the inside walls. This increases energy consumption.

• Switch on SuperFrost the day before defrosting to give the food a cold boost.
• Switch the appliance off to defrost. Pull out the mains plug.
• Wrap the frozen food, possibly still in the freezer basket, in paper or blankets, and store it in a cool place.
• Remove the plug from the drain opening. Remove the dividing wall or freezer tray and place it underneath the appliance so that the defrosted water escapes through the drain opening into the dividing wall or the freezer tray.
• Leave the lid open while defrosting. After defrosting mop up the remaining water and clean the appliance.

Do not use any mechanical devices or other artificial aids for defrosting other than those recommended by the manufacturer.

Cleaning

A failure to follow these instructions may result in food spoilt.

• Before cleaning, always disconnect the appliance from the mains. Pull out the plug or switch on the fuse.
• Surfaces in the food storage area must be cleaned at regular intervals. Only store foods that have been packed.

If the door is left open for a lengthy period, the temperature in the appliance’s compartments may rise dramatically.

• Clean the inside, equipment parts, and outer walls with lukewarm water and a little detergent. Do not use chemical solvents or any cleaning agents containing sand or acid.
• Motor compartment ventilation
  • Don’t open the cover.
  • Clean the ventilation holes by using a vacuum cleaner or brush.
  • Advisable to clean after 3 to 6 months.

CAUTION
Risk of damage to the appliance components and risk of injury due to hot steam.

Do not use steam cleaning equipment to clean the appliance.

• Ensure that no cleaning water penetrates into the electrical components or ventilation grille.
• Dry all parts well with a cloth.
• The ventilation grilles should be cleaned regularly. Dust deposits increase energy consumption. Ensure that none of the wires or other components are dislodged, bent, or damaged.
• Do not damage or remove the type plate on the rear side of the appliance. It is very important for servicing purposes.

If the appliance is left empty for a lengthy period, it must be switched off, defrosted, cleaned, and dried and the door is to be left open to prevent mold formation.
