6.6 Cleaning and maintenance
To achieve optimum operation (longer service life) it is important that the condenser
is cleaned to remove dust and dirt regularly, at least four times per year, in addition
to other requirements.
To access condenser, remove the 4 screws on the cover of the condenser element.
Remember! Disconnect mains plug before removal. Cleaning the condenser is best
performed by vacuum cleaning the condenser fins. On CU-450 Split they are
placed on the underside of the con- densor. Exercise caution. The fins are thin and
easily damaged. Replace cover after cleaning. Check drain on cold side to ensure
the water can run freely to the collection tank, drum or the like, on the cold room
side.
To avoid mould forming, bad smells etc, regular cleaning (including inside the cold
room) is essential. We recommend mild, warm soapy water for cleaning inside the
cold room.
Remove the screw, press the lid,
remove the screw and remove
the LED lamp.
Concerning the cooling room this cooling unit is built into, observe the following:
• Children aged from 3 to 8 years are allowed to load and unload the cooling room.
• Consider the temperature distribution in the cooling room concerning storage of
specific types of food.
• Opening the door for long periods can cause a significant increase of the tempera-
ture in the compartment of the appliance.
• Clear regularly surfaces that can come in contact with food and accessible drainage
systems.
• Store raw meat and fish in suitable containers in the refrigerator, so that it is not in
contact with or drip onto other food.
• If it is left empty for long periods, switch o, defrost, clean, dry, and leave the door
open to prevent mould developing within the cooling room.
• Keep clear of obstruction all ventilation openings in the appliance enclosure or in
the structure for building-in.
• Do not use mechanical devices or other means to accelerate the defrosting process,
other than those recommended by the manufacturer.
• Do not damage the refrigerant circuit.
• Do not store explosive substances such as aerosol cans with a flammable propellant
in the cold room of this appliance.
• Do not use electrical appliances inside the cold room of the appliance, unless they
are of the type recommended by the manufacturer.
• The door to use for assembling the cold room, shall be made in a way that can be
opened from the inside with a force smaller than 70N.
