The freezer was developed taking the different storage requirements of food items
into consideration. The freezer is equipped with freezing drawers in various sizes
giving room to all the little things as well as a big turkey.
To ensure that you get as much joy out of your freezer as possible, it is important
that you become familiar with the freezer functions and know how to use the ac-
cessories. Please read the instructions for use carefully before setting up and using
your freezer.
As these instructions apply to several freezer models, the equipment may vary from
model to model.
Before using the freezer
On receipt, check to ensure that the freezer has not become damaged in transport.
Transport damage should be reported to the local supplier before the freezer is put
to use.
Before lling the freezer with items of food, the freezer interior should be cleaned
with lukewarm water containing a mild detergent. Use a soft cloth. If the freezer has
been stored in cold surroundings (colder than +5°C), it must be allowed to stabilise
for at least 2 hours before being switched on.
Read more about setting up, building in, and installation on pages 12 and 13.

The freezer contains the environment-friendly, non-ozone-depleting refrigerant
R600a. As R600 is a ammable gas, it is important to avoid damage to the refriger-
ating circuit during transport and installation. If the refrigeration circuit is damaged,
avoid using a naked ame in the vicinity of the freezer and connecting power to
the cabinet. Also make sure that there is good ventilation in the room. If you are in
doubt, please con¬tact your supplier.
Transporting and moving the freezer
The freezer must always be moved in the vertical position. The freezer must not be
tilted more than approx. 40°. If the freezer has been tilted more than 40°, the power
supply must not be con¬nected until the appliance has stood upright for at least two
hours.
If the freezer is to remain unused for a time
If the freezer is to remain unused for a period of time, e.g. during refurbishment
work, switch it off by pressing the switch O(1) and disconnecting the power
supply to the cabinet and possibly pulling the plug out of the wall socket.
Empty, defrost and clean the freezer. Leave the freezer door slightly ajar. This will
prevent bad smells in the cabinet.

This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
Old refrigerators and freezers are often tted with complicated latches that can only
be opened from the outside. If you have an old unit like this stored away some-
where, or if you scrap it, remember to destroy the latch to prevent chil¬dren from
being exposed to danger by getting locked inside the unit.

Setting up and installation
Where to place the freezer
For safety reasons the freezer must not be installed outdoors; it must be placed in a dry
room. Never place the appliance close to sources of heat such as cookers or radiators,
and avoid placing it in direct sunlight. The surface on which the appliance is placed must
be plane. Do not use a frame or similar. The small wheels mounted at the rear of the
freezer make it easy to place it in the required position.
The freezer can stand freely on the oor or be built into a kitchen element or a refrigera-
tor element.
It is important that the appliance stands completely level and that there is good air
circulation over, under and around it. The freezer can be adjusted by turning the four
adjusting screws on the plinth. After adjustment, the feet and the two rear wheels must
be in contact with the surface on which the appliance stands.

GB/IE
Electrical connection
The appliance is intended for connection to alternating current. The connection values
for voltage (V) and frequency (Hz) are given on the nameplate in the cabinet.
Power must be connected via a wall socket with switch. The wall socket should be
easily accessible.
All earthing requirements stipulated by the local electricity authority must be observed.
The cabinet plug and wall socket should then give correct earthing. If in doubt, contact
your local supplier or an authorised electrician.
WARNING – This appliance must be earthed
The exible cord (mains lead) tted to this appliance has three cores for use with a
3-pin 13-amp plug. If a BS 1363 (13-amp) fused plug is used, it should be tted with
a 13-amp fuse.
IMPORTANT
The cores in this mains lead are coloured in accordance with the following code:
GREEN-AND-YELLOW: EARTH
BLUE: NEUTRAL
BROWN: LIVE
These colours might not correspond with the colour markings identifying the terminals
in your plug.
Note:
First connection to the mains.
The appliance provides information about the higher temperature (Hi alarm ) till the
moment of cooling.
The alarm is signalised by a sound signal and “Hi” caption on the display.
To cancel the alarm, press any push button.
Until the moment of cooling, the alarm is repeated every 15 minutes.
Such an operating mode is normal until the required temperature settings are
reached.

Maintenance and Service
The sounds that can be heard during normal operation:
• clicks - heard when the control activates or deactivates the compressor
• buzz - the sound of the compressor intensely working shortly after its activation
• crackles and clatter - coming from the cooling system, caused by expansion and shrin-
king of parts due to temperature differences before and after compressor activation
• rustle, gurgle, whistle - coming from the cooling system piping, caused by the co-
olant owing inside.
● Expanding and shrinking of parts caused by temperature changes causes crackling
sounds that may be heard
Easily corrigible sources of noise:
● noise caused by the appliance positioned not level - adjust the position with the
adjustable turn-in front feet.
● rubbing the adjacent piece of furniture - move the refrigerator a bit.
● creaking of the drawers and shelves - take out and put back the drawer or shelf.
