Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be used in the searching for or detection of
refrigerant leaks. A halide torch (or any other detector using a naked flame)
shall not be used.
The following leak detection methods are deemed acceptable for all refrigerant systems.
Electronic Ieak detectors may be used to detect refrigerant Ieaks but, in the case of FLAMMABLE
REFRIGERANTS, the sensitivity might not be adequate. or might need recalibration. (Detection
equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not apotential
source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at a
percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed, and the
appropriate percentage of gas (25 % maximum) is confirmed.
Leak detection fluids are also suitable for use with most refrigerants but the use of detergents
containing chlorine shall be avoided as the chlorine can react with the refrigerant and corrode the
copper pipe-work.
If a leak is suspected, all naked flames shall be removed/extinguished.
If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from
the system. or isolated (by means of shut off valves) in a part of the system remote from the leak.
All services shall be done by the accredited persons by the manufacturer according to local regulation.
Services related to breaking into the refrigerating circuit, opening of sealed components are not allowed
to be done in the user condition, must be taken to the designed location.
Sealed electrical components shall be replaced.
Intrinsically safe components must be replaced.

CONGRATULATIONS ON YOUR NEW COOLER
Note these instructions apply to all coolers. Installations of equipment may not exactly correspond to your
model.
INSTALLATION
Make sure that the cooler is not damaged on arrival. Your supplier must be notified of any transport damage,
within 24 hours of delivery.
The cooler should be placed in a warm, dry room, with suitable ventilation.
Place the cooler in such a way, as to allow the free circulation of air around it. That is, with at least 100mm
space all around it.
Never place the cooler in strong sunlight. The cooler be placed on a level surface. Make sure that it does not
rock.
If the cooler has been stored or transported cold, it must not be started before the compressor is judged to
have reached a temperature at least 41°F. It is recommended to clean up the cooler before starting it.

ELECTRICAL CONNECTION
The cooler must be connected to a socket with the correct voltage/frequency, as show on the nameplate.
The standard for u.s is 115V/50HZ. Voltage variations of ±10% are acceptable. Greater variations can
damage the cooler, and in such cases the factory warranty is not valid. In the case of extreme voltage
variation, above or below the standard, your local supplier will be able to advise you, what to do.
The cooler requires extra protection according to the Danish Heavy Current Regulations.
This also applies, if a new cooler is replaced, which did not have such protection. The purpose of extra
protection, is to protect the user from dangerous electric shocks, in the case of defect.
OPERATION INSTRUCTIONS
The temperature in the cooler is automatically regulated by a pre adjusted thermostat.
The position of the cooler, the ambient temperature, the number of times the lid is opened and for how long
the lid is opened, all these factors affect the temperature in the cooler, which should therefore not be placed
in sunlight or closed to a heat-radiating surface.
If your cooler is fitted with a lock, the key should be kept out of the reach of children. If your new cooler is to
replace an older one, which is not in use any more, you should remove the lock mechanism, on the old one,
before disposing it.
STORAGE OFF FOOD STUFFS
The cooler is only designed as a conserver, and is the not suited to cold freeze foodstuffs. In other words,
only refrozen food must be placed in the cooler. Next to that the cooler must not be filled beyond the height
limit of the contents line, or in cases where there is no such line, to within 100mm below the lid. This is to
ensure the product temperature less than 36°F.
DEFROSTING THE CABINET
In the course of time, a frost layer will be naturally formed within the cooler.
When this layer is 5-8mm thick, the cabinet should be defrosted the following way:
—remove the plug from the socket;
—open the lid and leave it open;
—loosen the frost layer using a plastic or wooden scraper.
The defrosting process can be speeded up by using bowls of hot water.
Never use sharp or pointed instruments
After final defrosting, the cabinet should be cleaned as described in section: Maintenance. the cabinet
should be thoroughly dried after cleaning.

OPERATION
Do not throw items into the storage area. Failure to heed these recommendations could result in damage to
the interior of the cabinet.
Refrigerated cycle
Refrigerators: During the refrigeration cycle, the evaporator fans wilt run continuously even when one or
more doors are open. The door switch will activate the lights when opened.
1. Every 6 hours, the unit will turn off and to allow the evaporator coil to defrost. The controller now
displays the defrost symbol. When the coil temperature reaches 41°F or after 20 minutes of defrost, the
unit will turn on again.
2. Anti-condensation heaters on door frames work in conjunction with the compressor.
3. The factory setting for the temperature range is 34°F to 38° F.

MAINTENANCE
This cooler can be cleaned using warm water and a mild detergent. Rinse with clean water to finish off.
Never use detergents that contain chlorine.
The lid may be cleaned in the same way as the cooler.
If a condenser and associated fan are fitted at the back bottom of the cooler, they can gather dust and dirt. If
cleaning is necessary, they should be vacuumed with a soft brush.
Please note that the parts behind the protective grille can be hot and rotating.
TROUBLE SHOOTING
If you are having problems with your cooler, please check the following point before calling service
personne
l:
—Is the cooler connected to the power supply?
—Is the socket switch on?
—Is the fuse in the switch cabinet intact?
—Has the earth leak circuit breaker (if there is one) cut out?
—Has there been power cut?
If the cooler is in a place that is very hot or with bad ventilation, make sure to provide adequate ventilation. If
the condenser mentioned in Section Maintenance is not clean, make sure to vacuum it.
If the above points have been checked and the cooler is still not working, please call service personnel.
Inform them the nature of the problem, the type of cooler, serial number and item number (provided on the
nameplate at the back of the cabinet).
Do not open the cabinet, as every opening hastens the thawing point. As s rule, the goods will not suffer
damage at the first 12 hours. If more time passes, the goods must be moved to another cooler.
DISPOSAL
When a worn-out cooler is to be disposed off, this must be done in a correct manner, with respect to the
environment. Please be aware of the rules covering the disposal of such terms; there may be special
requirements or conditions to be observed.
Information about disposal may be obtained from:
—your supplier;
—the relevant authorities (the Local Authority, environmental agencies, etc.).
SPECIAL POINTS TO NOTE
The information contained in these instruction for use, was correct at the term of printing. On account of our
constant produce development, however, we reserve the right to make changes in the cooler described here.
Naturally, we will attempt to keep instructions for use up to date.
If you are in doubt as to the correct use of the cooler, please contact your supplier, who will be able to advise
you.
The producer is not responsible for accident or problems, occurred as a result of wrong connection of the
cooler.
