Installing the Freezer
1. Always let an authorised electrician install the freezer (read the operating instructions).
2. The freezer should be located in a dry, cool place, out of direct sunlight. The freezer gives off a great
deal of heat when in operation. If the ambient temperature is too high, there is a risk that the freezer
will not operate correctly. Always ensure that the room is proper ventilated, so that the room
temperature does not exceed 25° C at most. Class N.
3. Place the freezer on a solid and flat substrate. This will eliminate any vibration and irritating noise. The
freezer should be placed with at least 30 cm free to the sides and against the wall.
Electrical Connection:
The machine meets current EU directives. Low voltage 2006/95/EEC.
Electromagnetic compatibility 2004/108/EEC.
The machine should be given extra protection in accordance with the Electricity Supply Regulations in order
to protect the user against dangerous electric shocks in the event of faults.
If the switch is for a three-pin plug, a three-pin plug should be used, and the conductor with yellow/green
insulation should be connected to the Earth terminal marked E.
Data regarding voltage and absorbed power / current are given on the rating plate.
Electrical connection must be made in accordance with the local regulations.

IMPORTANT!
Please remove the styropor plate witch is placed between the two
condenser coils on the back of the freezer before commissioning
the freezer!

Warning-Regulations require that this appliance must be earthed:
The manufacture declines all liability for injury to persons or animals and for damage to property resulting
from failure to observe the above procedures and reminders.
If the socket and plug are not of the same type, please have the plug or socket replaced by a qualified
electrician.
Do under no circumstances use extension leads or adaptors.
1. The freezer should be connected by an authorised electrician, or by the company, which sold the
freezer! Incorrect installation may damage the freezer.
2. Place the freezer on a flat floor, which can take the weight of the freezer.
3. The electrical installation should be earthed.
4. Do not use extension cables, but connect the freezer directly to a fixed installation. If the freezer is
connected to a long extension cable there is the risk that the cable will become hot.
5. The freezer should be placed in a dry location, and should not be subjected to water on the cabinet. If
water gets into the electrical parts it may cause short-circuiting.
6. In the event of functional or electrical irregularities please contact an authorised servicing engineer
Before Commissioning:
Clean the freezer both inside and out using a damp, wrung out cloth. Dry with a dry cloth.
The smell from the plastic parts in the freezer will disappear once the freezer has been cooled down.
Start Procedure
Put the plug in the socket. The freezer should run for at least 1 hours before the thermostat is changed.
(Stabilisation of the cooling system).
Caution!
Do not place bottles or boxes containing carbonic acid or chemical agents in the freezer.
Do not place inflammable liquids such as ethane, petrol or alcohol in the freezer. Risk of explosion!
No bottles or tins should be placed in the freezer, as they could explode and cause injury to personnel.

POTENTIAL FREE ALARM CONTACT
The purpose of having the potential free contact (CTS) is to make it possible to receive a signal
when the controller of the freezer registers some kind of error. By using the potential free contact,
it is ensured to receive the signal regardless of which kind of surveillance system is used.
As the potential free contact works like a switch on/off contact, it is independent of any possible
software or hardware that might be used in the surveillance system.
You CANNOT se WHAT caused the setting of the alarm, but only that an alarm has been set off
and therefore has to be checked in order to locate the problem.

There is no guarantee for the contents of the freezer.
If the freezer does not work: call an authorised servicing engineer!
Contact the distributor or an authorised service repair shop!
Cleaning and Maintenance of the Freezer:
1. After prolonged operation a layer of frost or ice may form on the cooling elements. If the layer of frost or
ice becomes too thick, it will increase the energy consumption.
2. Take the contents out of the freezer. Pull out the plug and leave the door open until the ice can be
removed. (Remember safety gloves).
3. Remove the frost layer from time to time with a plastic scraper. Caution! Do not use any metal objects.
Risk of damage!
3. Dry the inner container with a cloth until it is not damp any longer!
4. Clean the outside of the freezer with a damp cloth. Be careful not to get damp (water) on the
electrical parts, or water into the vent holes, as water and damp may damage the electrical
parts and cause the freezer to short-circuit!
6. Use authorised cleaning products. The use of alcohol, dissolvent and alkaline cleaning agents
is prohibited.
4. As a rule of thumb, the appliance should be completely defrosted once a year.
5. The refrigerating machine with the heat exchanger - metal grating on the rear of the freezer should be
cleaned (dusted) once a year, e.g. with a paintbrush or vacuum cleaner. Dust deposits raise the energy
consumption and in extreme cases may lead to failure of the refrigerating machine due to overheating.
Ensure that no cables are pulled off or bent.
Do not put bottles containing carbonic acid or inflammable products in the freezer.
Disposal and scrapping of the freezer:
Remove the lock, so that there is no risk of children getting locked in the freezer whilst playing.
Note:
Before carrying out maintenance, unplug the appliance.
Do not use abrasive products, stain removers (e.g. acetone, trichloroethylene) to clean the appliance.
Disposing of the Freezer:
To prevent harmful environmental effects, contact the distributor and ask where the freezer should be
delivered.
Remove the locking function so that children cannot be locked in the freezer whilst playing.
You can obtain information on the disposal of refrigeration appliances from:
!Your supplier
tAuthorities (The Local council, Ministry of the Environment, etc.)
