CU-450 Split ECO is our split unit, with capacity of 10,000 litres respectively. It is
designed for chilling food for use in private households and similar applications.
The correct temperature in the cold room will depend on correct construction and
insulation.
The warm and cold elements of split units are separate. The cold element is installed
in the cold room and consists of: evaporator, fan, thermostat, capillary tubes, fil-
ter and light fitting with switches. The warm element is installed in the machinery
compartment and consists of: refrigeration compressor, condenser, fan, electrical
cabinet and defrosting timer. There are several reasons why the warm element
should not be installed in an adjacent room: heat emission, lack of space, aesthetic
grounds etc.
The units require a power supply of 220-240VAC 50 Hz and must be connected to
an earthed min.10A mains socket. The power cable is connected to the condenser.
If the cable is not long enough (2.6m) call an electrician to install a socket closer.
The mains socket must be easily accessible for installation/service. The warm ele-
ment can be located up to 10m pipe length from the cold room, and the two parts
must be connected by copper pipe and electric cable. The mains socket must be
easily accessible for installation/service.
It is essential that there is sucient ventilation around the warm element in the
machinery compartment. Ambient temperature on the warm side outside the cold
room must always be higher than inside, but must not exceed 38°C, or be less than
16°C.
Scandinavian Appliances AS also supplies other products that you need for a self-
build cold room.

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.

8. Disposal of used products
This is based on guidelines laid down in environment protection legislation accord-
ing to the European Parliament’s directives on disposal of electric and electronic
products (WEEE). The directive is intended to protect and improve the environ-
ment, protect human health and exploit natural resources sparingly and sensibly.
We kindly ask you, the end-user, to observe the following:
1. If the product stops working, including after having been repaired, check if it can
be repaired before you dispose of it. If in doubt, contact your vendor or dealer for
further information on possible repair of the product.
2. If the product is at the end of its service life – i.e. cannot be repaired or recycled,
do not dispose of the product with other unsorted refuse. Contact your local waste
disposal or recycling facility, in order for them to collect the product for recycling.
To contribute to the improvement and recycling process of this product, do not
remove or destroy parts of the product before collection. By doing so you can
reduce its potential for recycling.
NOTE: Disposing of electronic and electrical products in landfill and by incinera-
tion can cause severe harm to the environment. When worn out substances
are not recycled, new resources have to be used for new products. This
represents a loss of resources, as the consumption of energy, transport and
the negative eect on the environment if such processes is great. Another
problem is that this type of product can contain coolants with gases such
as hydro fluorocarbon (HFC). HFC gases exacerbate the greenhouse eect
which in turn causes a warmer climate when they are released into the
atmosphere.
The symbol below, which is also found on the product, indicates separate collection
of electric and electronic appliances based on the European Union’s WEEE
directive.
Disposal Old appliances still have some surplus value. An environmentally friendly
approach will ensure that valuable raw materials are recycled. The refrigerants
used in your equipment and insulation materials require special handling proce-
dures. Make sure there is no pipe damage on the back of the equipment before
handling. Up-to-date information on the options for disposing of old equipment
and packaging from old equipment can be obtained from the local municipal
oce.
If the product carries this symbol, it is your respon-
sibility as consumer to contribute to recycling by
ensuring the product is not disposed of with other
refuse, but is delivered to your local refuse depot
and recycling centre. Please contact the relevant
authorities in your area for more information on
collection schemes.
Finally, make sure you comply with all recycling legislation applicable in your
municipality or your country.
