TIPS, MAINTENANCE & SERVICE
TIPS AND SUGGESTIONS
• Fresh and frozen foods should not be stored beside each other in the cabinet. Doing so may cause fresh food
to freeze and/or spoil.
• When the appliance is set at temperatures of 0° or lower, do not store glass bottles or liquids such as beer,
milk, juices or soft drinks in the unit as these may freeze and shatter, leak or burst.
• Items such as fruit and vegetables should be stored closer to the top of the cabinet as this area is normally
slightly warmer. This will reduce the risk of spoiling and ensures that damage is not caused by being crushed by
heavier items.
• To improve the efficiency of your Fridge/Freezer it is best to have the cabinet as full as possible at all times. A
full cabinet will have lower power consumption compared to a half empty one. When the cabinet is full there is
little air space between the goods and the cold air is trapped. When there is a large air space the cold cannot
be captured and held. On a trip it is a best to replace finished products with bottles of water or similar. This will
fill the empty spaces and keep the coldness of the cabinet.
• Frequent opening of the lid will allow warm air to enter the cabinet. Where possible keep the number of times
you open the lid to a minimum.
• When located in the rear of a car or trailer, it is recommended that the appliance is kept away from direct
sunlight to reduce the risk of increased heat. It should also be provided with suitable ventilation to guarantee
efficient power consumption and performance. Remember that when a vehicle is parked in the sun that on a
day where the ambient temperature is +30°C, the interior of the vehicle can reach +55°C.
MAINTENANCE & SERVICE
Your Fridge/Freezer is delivered cleaned by the factory - you should nevertheless clean it prior to first using it. Use a
cloth which has been slightly moistened with lukewarm water. Take care that no water drops into the seals as this
could possibly damage the electronics. Clean your Fridge/Freezer periodically and whenever it gets dirty.
CAUTION WHEN CLEANING:
• DO NOT use solvents or agents with sand or acid in them for cleaning your Fridge/ Freezer.
• DO NOT use brushes, graters or hard / sharp tools to clean your Fridge/Freezer.
• Before cleaning, the power cable should be disconnected and the Fridge/Freezer switched OFF.
• Clean the Fridge/Freezer inside and out with a damp cloth. For stubborn dirt, use some sodium bicarbonate
dissolved in lukewarm water.
• After washing, rinse with clean water and dry carefully.
For additional queries, service and maintenance please contact our After Sales Support. They will provide you
with expert advice on further information you may require.
