Safety tips
Do not use electrical appliances such as hair dryer or heater to defrost your
freezer.
Do not store inflammable gases or liquids inside your DC refrigerator.
Disposal
Old appliances still have some residual value. An environmentally friendly
method of disposal will ensure that valuable raw materials can be recovered
and used again. The refrigerant used in your appliance and insulation
materials requires special disposal procedures. Ensure that none of the pipes
on the back of the appliance are damaged prior to disposal. Up-to-date
information concerning options for disposing of your old appliance and
packaging from the new one can be obtained from your local council office.
This symbol on the product or in the instructions means that your electrical
and electronic equipment should be disposed at the end of its life separately
from your household waste.

Installation Instructions
Location
When selecting a position for your appliance you should make sure that the
floor is flat and firm, and the room is well ventilated with an average room
temperature of between 16°C and 35 °C. Locate the appliance away from
direct sunlight and source of heat (stove, heater, radiator, etc.) Direct sunlight
may affect the acrylic coating and heat sources may increase electrical
consumption. Extreme cold ambient temperatures may also cause the
appliance not to perform properly. This unit is not designed for use in a
garage or any other outside installation. Avoid locating the appliance in moist
areas. It must therefore be installed so that the appliance has at least 15cm/6
inches from the wall at the back and side. The appliance door can either open
to the right or the left, depending on whichever suits you. See page 5-7 if you
want to reverse the door swing. Do not drape your appliance with any
covering.
Moving the appliance
Position your appliance in front of its final operating position and gently slide
the appliance into position. A minimum of two persons must be used to move
the appliance.

Operating Your Refrigerator/Freezer
Switching on your DC Refrigerator
1. Before connecting the appliance to the DC power supply, make sure
that the thermostat control dial is set at position 0. This is located on
the right part of the fridge.
2. Turn the thermostat knob clockwise to set it to the desired position.
Bear in mind that the higher the number, the colder the temperature.
3. To ensure that the appliance is cool enough to sufficiently chill your
food wait 24 hours before filling with food.
Adjusting the temperature
The internal temperature of your appliance is controlled by a thermostat.
Position 7 makes the appliance coldest and position 1 makes it warmest and 0
turns the appliance off. The recommended setting for the appliance is
between 1-4 for colder working environment (i.e. during winter) and 4-6 for
hotter environments. The temperature of the appliance may not operate at
the correct temperature if it is in a particularly hot or cold room or if you open
the appliance door often.

Care and Maintenance
Defrosting
Your DC Refrigerator is frost free, and the ice build in will normally
defrost automatically. However, if the freezer door is left open for a
period of time, ice may build in the freezer compartment. Temporarily
this can be scraped away using a plastic scraper. NEVER use a metal or
sharp instrument. Complete defrosting will however become necessary
if the frost layer exceeds 5cm (2”) to maintain the efficiency. This should
be carried out if the frost build up cannot be scrapped away, or if it
begins to interfere with the food storage. Choose a time when the
stock of food is low and proceed as follows:
1. Take out the chilled food, turn the DC refrigerator off at the
power supply and leave the door open. Ideally the chilled food
should be put into another refrigerator. If this is not possible,
wrap the food in several sheets of newspaper or large towels
and keep it in a cool place.
2. Scrape away as much frost build up as possible using a plastic
scraper. Thawing off the remainder can be sped up by placing
bowls of hot water inside the fridge cabinet and closing the
door. As the solid frost loosens, pry it away with the plastic
scraper and remove.
3. When defrosting is completed, clean the DC refrigerator as
described in the previous column.
Noises inside the DC Refrigerator
If you have not owned this type of appliance before, you may notice it
makes some rather unusual noises. Most of these are perfectly normal,
but you should be aware of them.
Humming, purring or pulsating
This is the compressor motor working, as it pumps the refrigerant
around the system.
Gurgling, whooshing
These noises are caused by the circulation of the refrigerant liquid in
the cooling system. It has become more pronounced since the
introduction of CFC free gases. This is not a fault and will not affect the
performance of your appliance.
Shut the door!
To prevent cold air escaping, try to limit the limit the number of times
you open the door. When returning from shopping, sort foods to be
kept in your appliance while the door is closed and only open it to put
food in or take food out.
NOTE:
ALWAYS WRAP AND STORE RAW MEAT, POULTRY AND FISH ON THE LOWEST
SHELF AT THE BOTTOM OF THE APPLIANCE. THIS WILL STOP THEM FROM
DRIPPING ONTO, OR TOUCHING OTHER FOODS. DO NOT STORE
INFLAMMABLE GASES OR LIQUIDS IN THE APPLIANCE.
Replacing the bulb
1. Ensure the appliance is unplugged and disconnect from the
power supply.
2. Remove the bulb cover and unscrew the bulb in counter-
clockwise direction.
3. Replace the bulb with a new one.
4. Replace the cover and reconnect the appliance to the power
supply.
Reversing the Door Swing:
Ensure the appliance is unplugged and empty. Adjust the two leveling
feet to their highest position. We recommend you have someone assist
you.
