Use
Freezer
• The freezer compartments are designed to store only frozen food.
• Never put hot or warm foods in the freezer, allow them to cool fully
before putting them into the freezer.
• Follow the instructions on the food packaging for storage of frozen
food. If no information is provided, foods should not be stored for
more than three months after the purchase date.
• Store food in small packages (ideally less than 2.5kg). This reduces
the freezing time and improves the quality of the food after thawing.
• Wrap food before putting into the freezer. To stop the wrapping
sticking together, ensure it is dry.
• Label the food before freezing with information including type of
food and dates of storage and expiry.
• Once food is thawed, it must not be refrozen unless it has been
completely cooked. Only defrost as much food as is required, to
prevent wastage.
• Bottled or canned drinks should not be stored in the freezer
compartments as they could explode.
• Check the rating plate to confirm the maximum amount of fresh food
that can be frozen within a 24 hour period.
• Do not attempt to freeze more than the maximum amount.
• To freeze fresh food more quickly, switch the dial to setting 5 a few
hours prior to placing the food in the freezer.

7
Storage and use
This freezer is suitable for storing deep frozen food (food which
has already been frozen before being added to the freezer), for
storing fresh food for a short period (2-3 weeks) by freezing it and for
making ice and ice cream.
Always remember to observe and adhere to the recommended
expiration date of food.
Fresh food, and food which needs to
be stored for a long period, should be
kept at a temperature of -18°c or below.
For this, we recommend using setting 4
or 5.
If food only needs to be stored for a
short period then a setting of 2 or 3 will
suffice.
Please remember: Ice cream or ice
for drinks should be allowed to sit at room temperature for several
minutes before being used as they can still be cold enough to cause
damage to skin and lips.
Please note: The freezer should be defrosted regularly. If you are
unsure of when then it is advisable to do so when, and if, the ice
layer reaches 5mm thickness.

Controls
Thermostat dial
The temperature controls for this fridge are simple and consist of a
single thermostat dial (1). To change the temperature, simply turn the
dial left and right to cycle through the available settings. A centrally
located embossed arrowhead indicates the setting. The settings
available range from OFF to 5 with OFF being the ‘Off’ setting and ‘5’
being the coldest.
After changing the temperature setting, the time taken to achieve
the new temperature will depend on how big the change is from the
previous setting.
Switching On and Off
When the fridge is connected to a power supply the power
indicator (2) will illuminate and the freezer will begin cooling unless
the thermostat dial is set to ‘OFF’. To begin cooling, turn the dial to a
setting between 1 and 5. The temperature warning indicator (3) will
illuminate if the interior is not yet cold enough. To switch the appliance
off, turn the dial to setting ‘OFF’. If you are turning the appliance off for
a long time, then switch off the mains power supply also.

Super freeze function
The freezer is equipped with a super freeze function which causes
the compressor to run continuously. This is intended to be used for
freezing large amounts of produce as quickly as possible. For best
results, switch the function on a few hours before introducing the
items to be frozen. To avoid damage to the system, do not use this
function for more than 24 hours.
To switch the super freeze function on simply press the superfreeze
button (5). The super freeze light (4) should illuminate.
To switch the function off, simply press and hold the super freeze
button (5) for 3 seconds. The super freeze light should extinguish.
Care and cleaning
Always disconnect the appliance from the power supply before
any cleaning or maintenance.
The freezer should be cleaned using a solution of bicarbonate
of soda and lukewarm water. Do not use abrasive products or
detergents. After washing, rinse and dry thoroughly.
Clean the drawers separately by hand with a mild solution of washing
up liquid and water. Do not put them in the dishwasher.
If the appliance is not to be used for prolonged periods of time,
unplug and clean the appliance. The doors should be left slightly
ajar to prevent the formation of mildew and unpleasant odours. It
is important however that you ensure that no child or person could
become trapped in the appliance.

10
Defrosting the freezer
Do not use heaters or defrosting sprays in this appliance.
Never use any metallic or sharp objects such as knives or forks to
remove the ice as this could damage the lining.
The freezer compartment should be defrosted regularly to ensure the
most efficient running of the freezer.
Once the ice is more than 5mm thick, the freezer should be defrosted.
• 24 hours before defrosting the freezer, turn the thermostat dial to
setting 5 or switch on the super freeze function to ensure the frozen
food is fully frozen.
• Before switching off the freezer, wrap the the frozen food in sheets
of paper and store it in a cool place.
• Switch the appliance off at the thermostat dial and the mains and
then remove the freezer drawers.
• To speed up the defrosting process, place a bowl of warm water in
the base of the freezer compartment.
• The freezer should be cleaned using a solution of bicarbonate
of soda and lukewarm water. Do not use abrasive products or
detergents. After washing, rinse and dry thoroughly.
• Clean the drawers separately by hand with a mild solution of
washing up liquid and water. Do not put them in the dishwasher.
• Once cleaning is complete, reconnect the power.

Troubleshooting
If you have any problems with your appliance, you should check
the troubleshooting prior to calling CDA Customer Care to prevent
unnecessary service calls and potential cost.
If the appliance is not working, check the following:
• There is power to the appliance.
• The house fuses are intact and the fuse in the plug has not blown.
• The on/off switch is not set to off.
• The plug socket is functioning fine. To check this, plug another
electrical appliance in to see if the socket is faulty.
If the appliance is working, but not very well, check the following:
• The appliance is not overloaded.
• The thermostat is set to an appropriate temperature.
• The doors are closing properly.
• The cooling system at the rear of the appliance is clean and free of
dust, and not touching the rear wall.
• There is enough ventilation at the side and rear walls.
If the appliance is noisy, check the following:
• The appliance is level and stable.
• The side and rear walls are clear, and there is nothing resting on
the appliance.
• Note: The cooling gas in the refrigerator may make a slight bubbling
or gurgling noise, even when the compressor is not running.

12
If there is water in the freezer, check the following:
• The appliance has power and the green power light is on.
• There are no items touching the rear wall of the appliance. If there
are, adjust their position so that they no longer touch it.
• That there is some resistance when opening the door of the
appliance. If it opens at the slightest touch it may mean that the
door seal needs to be replaced.
• Inspect the door seal for any kinks, debris or damage. If you notice
any, and are unable to resolve the issue yourself, contact CDA
Customer Care so that the seal can be replaced.
If excessive ice or frost has formed in the freezer:
• It is normal for some ice and frost to form in the freezer. This does
not constitute a fault with the appliance. If the ice layer is thicker
than 5mm, try defrosting the appliance.
• Ensure that the thermostat is at the position you intend for it to be
and hasn’t been accidentally set to the highest setting. If the
freezer is set to the maximum, try lowering the setting.
• Check that there is some resistance when opening the door of the
appliance. If it opens at the slightest touch it may mean that the
door seal needs to be replaced.
• Check the door seal for any kinks, debris or damage. If you notice
any, and are unable to resolve the issue yourself, contact CDA
Customer Care so that the seal can be replaced.
If the temperature warning light (
!
