Caring for the environment

Disposal of the packing
material

The transport and protective packing
has been selected from materials which
are environmentally friendly for
disposal, and can normally be
recycled.

Ensure that any plastic wrappings,
bags etc. are disposed of safely and
kept out of the reach of babies and
young children. Danger of suffocation!

Rather than just throwing these
materials away, please ensure that they
are recycled.

Disposal of your old appliance

Please ensure that the appliance
presents no danger to children while
being stored for disposal.

It should be unplugged or
disconnected from the mains electricity
supply by a competent person. The
plug must be rendered useless and the
cable cut off directly behind the
appliance to prevent misuse. See the
"Warning and Safety" section of this
booklet for further details.

Electrical and electronic appliances
often contain materials which, if
handled or disposed of incorrectly,
could be potentially hazardous to
human health and to the environment.
They are, however, essential for the
correct functioning of your appliance.

Please dispose of your old appliance at
your local community waste collection /
recycling centre and not with your
household waste.

Take care not to damage the pipework
at the back of it before or during
transportation to an authorised
collection depot.
In this way, refrigerant in the pipework
and oil in the compressor will be
contained, and will not leak out into the
environment.

avoid the risk of injury do not allow
children to play on or near it, or to play
with the controls. Supervise its use by
the elderly or infirm.

which is very environmentally friendly.
Although it is flammable, it does not
damage the ozone layer and does not
increase the greenhouse effect. The
use of this environmentally friendly
coolant has, however, led to a slight
increase in the noise level of the
appliance. In addition to the noise of
the compressor, you might be able to
hear the coolant flowing around the
system. This is unavoidable, but does
not have any adverse effect on the
performance of the appliance.
Care must be taken during the
transportation and installation of the
appliance that no parts of the coolant
system are damaged. Leaking coolant
can damage the eyes.
In the event of any damage:

- avoid open fires

- air the room in which the appliance is

located for several minutes and

- contact the Service Department
for advice.

should be installed in. In the event of a
leakage, if the appliance is in a small
room, there is the danger of
combustible gases building up.
For every 8 g of coolant at least 1 m
room space is required. The amount of
coolant in the appliance is stated on the
data plate inside the appliance.

the rating on the data plate
corresponds to the voltage and
frequency of the household supply.
This data must correspond in order to
avoid the risk of damage to the
appliance. Consult a qualified
electrician if in any doubt.

The electrical safety of this

appliance can only be guaranteed
when continuity is complete between it
and an effective earthing system which
complies with local and national safety
regulations. It is most important that this
basic safety requirement is present and
regularly. Where there is any doubt, the
household wiring system should be
inspected by a qualified electrician.
The manufacturer cannot be held liable
for the consequences of an inadequate
earthing system (e.g. electric shock).

Safe operation of the appliance is

only assured if it has been installed
and connected in accordance with
these operating and installation
instructions.

Installation work, maintenance and

repairs may only be carried out by
suitably qualified and competent
persons to ensure safety.
Repairs and other work by unqualified
persons could be dangerous and the
manufacturer will not be held liable.
Ensure current is not supplied to the
appliance while maintenance or repair
work is being carried out.

The appliance is only completely

isolated from the electricity supply
when:

it has been switched off at the socket

–

and the plug has been withdrawn.

– the mains fuse has been withdrawn,

or

– the screw-out fuse is removed (in

countries where this is applicable).

Do not connect the appliance to

the mains electricity supply by an
extension lead.
Extension leads do not guarantee the
required safety of the appliance (e.g.
danger of overheating).

Use

Never handle frozen food with wet
hands. Your hands may freeze to

the frozen food. Danger of frost burn.

Do not take ice cubes out with your

bare hands and never place ice
cubes or ice lollies in your mouth
straight from the freezer. The very low
temperature of the frozen ice or lollies
can cause frost burn to the lips and
tongue.

7

Warning and Safety instructions

Do not refreeze thawed or partially

thawed food.
Defrosted food should be used up as
quickly as possible, as food soon loses
it nutritional value and goes off.
Defrosted food may only be re-frozen
after it has been cooked.

Never store explosive materials in

the appliance. Thermostats
switching on may produce sparks
which could present a fire hazard.
Flammable compounds could explode.

Do not use any electrical

equipment in this appliance, e.g.
ice cream makers. Danger of sparking
and explosion!

How to save energy

Normal energy
consumption

Defrosting Defrost the freezer when a layer of

ice one centimetre thick has built
up.

Increased energy
consumption

A layer of ice hinders the cold
from reaching the frozen food, and
causes an increase in energy
consumption.
