1.1 USE, OPERATION AND HANDLING
This unit should be used by adults and only handled by quali󰄈ed personnel. The manufacturer accepts no liability for
damage caused by improper use or unauthorised repairs.
This unit is heavy. Take the necessary precautions during installation.
This unit should be earthed directly to protect against electrical shock. The earth cable should not be cut or modi󰘰ed.
If any electrical work is necessary for installation or maintenance of the unit, this should be done by quali󰘰ed personnel.
Ensure that the power cable is not trapped beneath the unit or in contact with the motor.
To ensure that the unit functions properly, it should be installed somewhere with adequate ventilation and a temperature no higher
than 32OC (climate class N).
Do not forget to disconnect the unit before carrying out any repairs, maintenance or cleaning.
This unit is 󰘰tted with a refrigeration circuit. This should not be damaged by any cleaning or maintenance.
The unit should only be used for the purpose for which it was designed and under the conditions speci󰘰ed in the manual.
1.2 UNIT PACKAGING, TRANSPORT AND RECEPTION
The packaging protects the unit against possible damage during transport. All the material used are environmentally-friendly and can
be recycled or reused.
The unit is palletised and wrapped in a wooden structure. It should be transported, stored and unloaded in the position: ALWAYS
HORIZONTAL. If this is not the case, the unit should be left standing for a few hours before operation in order to allow the compressor
oil to settle.
Check that the packaging has not been damaged during transport. If damage is present, make a claim with the transport company
or agency that provided the transport service IMMEDIATELY (no damaged units may be returned without reporting the damage and

without authorisation after resolving this situation with the transport agency).
Cut the transport strips and remove any plastic and cardboard, taking care with any wood staples or splinters. Do not mark or strike
the unit with the tools used for unpacking. Always leave the transport pallet until last.
1.3 UNIT INSTALLATION
Move the unit with a pallet jack to the position where it will be installed. Carefully remove the pallet cover so as not to damage the unit.
Then remove all the protective elements from the unit (cork, 󰘰lm, etc.).
Do not place the unit in the sun, near any heat sources or near any hot air vents.
Leave enough free space around the unit where the air vents are located and do not cover these vents, so that hot air can be vented
without obstruction.
1.4 POWER CONNECTION
Before plugging in a refrigerated unit, check that a suitable voltage supply can be provided according the documentation accompanying
the unit.
The power cable should have a section matching the power consumption of the unit and must have an EARTH connection (the lack
of an earth connection poses a serious risk to your safety and immediately cancels the manufacturer’s guarantee).
Do not insert objects into the protective grilles on the refrigerating unit.
Disconnect the power to the unit before cleaning or performing any maintenance.
For your own safety, do not walk barefoot on a wet 󰘱oor or with wet hands in case of electrical shock.
If the power cable is damaged and to avoid any possible harm to yourself, it should be replaced by the manufacturer via its after-sales
technical service or by similar quali󰘰ed personnel.
This unit is designed to be STATIC (not mobile).
The electrical components (thermostat, connections, etc.) should only be handled by quali󰘰ed personnel as improper adjustment

could lead to serious damage to unit operation or the products stored in it.
The place where the unit is installed should have the following:
. Electrical wiring with a di󰘯erential switch and thermal-magnetic circuit breakers.
. An earthed power supply connection.
1.5 UNIT GUARANTEE
- Due to the demanding conditions to which our products are subject for industrial use, they are guaranteed for a period of TWO
YEARS, from the date of sale, against any manufacturing fault provided that they are handled by quali󰘰ed professionals in accordance
with current regulations and under normal conditions.
- The terms of the guarantee must be met in order for the same to be applicable and, in any case, the fault detected with the unit
must be accepted by our Technical Department. In order for the latter to take place, the defective parts must be sent to the Technical
Department for assessment.
- Our guarantee only covers material replacement at no cost to the buyer. Under no circumstances do we accept liability for any
damage that may have been incurred due to the fault, either directly or indirectly.
- The guarantee only covers manufacturing faults. Under no circumstances does the guarantee cover faults caused by incorrect
installation, power supply, etc. not related to a manufacturing fault, nor damage caused by adverse weather conditions (storms,
lightning strikes, wind, etc.) or any other kind of force majeure.

2.1 DESCRIPTION
Our units are designed for the storage of food products. This unit is classi󰘰ed under climate class N and is made from non-toxic materials
and steel. The refrigerating system contains R134a gas for refrigeration units. The body is injected with CFC-free polyurethane at a
density of 40 Kg/cm3. Optimum operating temperatures: +4oC and 8oC.
2.2 START-UP
Connect the power cable to the electricity supply and, if the display message reads OFF, press the on button on the thermostat.
Once connected, check that the refrigerating unit (compressor and fan) is working. The thermostat is programmed to perform the
start-up and shut-down operations. The unit will function automatically from this point forward.
On sushi models, the refrigerating unit operates non-stop until the unit is manually switched o󰘯.
In the event of a malfunction, do not touch anything and contact the supplier who provided the unit.
NOTE: The external switch turns the internal light on and o󰘯. Check that this is working properly by changing the switch position and
ensuring that the lights turn on and o󰘯.
2.3 TIPS
Let the unit reach the optimum operating temperature before placing food inside.
Do not place hot food in or on the unit.
Remember that this unit is for displaying food products. Refrigerated food products should therefore be used up each day. The unit
should be emptied and cleaned at the end of each day to avoid the accumulation of condensation in the tray and the formation of ice.
Under no circumstances should the unit be used to store food for long periods of time.
Do not leave the cover open for a long time as this may a󰘯ect the temperature inside the unit.
2| DESCRIPTION AND OPERATION OF THE UNITS

7
If you intend to store food with an odour that could a󰘯ect the smell or taste of the other food, wrap it or keep it in an air-tight container.
If the unit is not going to be used for an extended period of time, disconnect it from the power supply, remove any food, clean the
inside and leave the cover slightly open.
Do not use mechanical devices or other means to accelerate the defrosting process.
Do not use electrical appliances inside the compartments used for storing food other than those recommended for this purpose.
3.1 CLEANING AND UPKEEP
One of the 󰘰rst tasks to do after unpacking the unit is to clean the interior with water and a neutral soap product.
The condenser should be cleaned regularly, keeping it free of foreign bodies. A sti󰘯 brush (not a wire brush) is recommended for
cleaning the condenser. If you lack the equipment necessary, ask the technical service to clean the unit for you. This will ensure the
refrigerating unit continues to perform properly.
Clean the condenser to ensure it performs properly.
The exterior should be cleaned daily using soapy water as food scraps and grease can damage the various parts of the unit.
Do not damage the refrigeration circuit when cleaning as this may lead to serious consequences.
We do not recommend the use of aggressive products, such as bleach, acids, etc.
3.2 MAINTENANCE
Maintenance should be performed by quali󰘰ed personnel. Maintenance operations will depend on the conditions of your premises
and the use made of the unit.
Maintenance tasks should include cleaning the condenser and places where food scraps or liquids accumulate but not reached by
the daily cleaning process.
