IMPORTANT INSULATION CONDITIONS
Climate
The climate conditions of the environment where the counter is installed must be within the tempera-
ture range established by the counter class. To be within these parameters, it could be necessary to
install an air-conditioning system. The system should include an air humidity controller as excessive
humidity harms proper operation of the counter.
Dehumidifying the air with an air conditioner instead of with evaporators could be more economical as
the counters operate at lower temperatures and therefore absorb more electric energy at the same
cooling capacity efficiency.
Grouping several counters together in the same area could be advantageous operating-wise but could
be inconvenient for customers.
Air draughts
The counters must be positioned in such a way to limit or avoid air draughts which keep them from
operating properly. The counters must not be installed near doors or in areas exposed to strong air cur-
rents coming from ventilation or air conditioning vents, for example.
The design of the ventilation systems must take into account that there must be low air speed near
the counters, which in any case must never exceed 0.2 m/s.
Special attention must be paid to heating vents.
Thermal radiation and lighting
To limit the negative effects of radiant heat, make sure that the counters are not exposed to sunlight,
diffusers or air ducts, to uninsulated roofs or walls heated by sun or other heat sources. The penetra-
tion of radiant heat inside the counter increases operating costs and downgrades performance. Do not
point spotlights or other concentrated lighting devices towards the inside of the counters. External
fluorescent lighting is preferable to incandescent lighting and should be used.
Should incandescent lights be used, make sure that the lighting devices are appropriately ventilated by
large ventilation slots.
Surfaces at room temperature radiate enough heat to harm proper operation of the counter. This ef-
fect can be limited by installing heat-reflecting ceilings or placing the counters one in front of the
other.
Condensation
It is normal for absolute humidity to condensate on a cold surface if the air dew point is higher than
the temperature of the surface. Regardless of how a counter is insulated, condensation will be formed
if there is no ventilation around it. We therefore recommend leaving at least 60mm between the
counter and wall or any other object which can obstruct proper air circulation around the counter.
Transport and handling
The counter is shipped packed in a plastic sheet and fastened on two wooden boards which act as a
delivery support to facilitate handling. Keep the counter fully packed until it reaches the installation site
to prevent it from being damaged during transport. When the counter has been unpacked, do not dis-
pose of the packaging in common waste disposal centres, but contact specific waste collection facili-
ties for the recovery of materials and substances harmful for the environment.
The counter must be moved using a forklift truck, paying attention to the electrical devices and drains
underneath the counter.
Cleaning
The frequency at which display cabinets for vegetables, meat and other unpacked products must be
cleaned varies depending on the displayed product. Counters for preserving products such as meat,
dairy products and cold cuts must have the display surface cleaned at least once a week to prevent
the development and accumulation of bacteria.
The bottom of the tank must be washed frequently in cabinets subject to leakage of liquids or other
food products.

7
De Rigo Refrigeration s.r.l.
The frequency of cleaning however depends on how the counter is used and on hygienic require-
ments or other particular reasons. Blockage of the water drain can cause a failure which could possibly
damage other parts of the counter. Therefore qualified technical personnel should clean the drains pe-
riodically.
We recommend:
 Wait for the counter temperature to come close to room temperature, empty the counter and clean it
without using abrasive products or solvents;
 Daily cleaning with water and non-aggressive detergents of the outside zones surrounding the dis-
play area and the top parts of the shelves in contact with the product, paying special attention if meat
counters. Do not touch electric parts with a wet cloth;
 Weekly, full cleaning of bottom shelves with water and non-aggressive detergents, lifting them with
the supplied hook and wearing the protective gloves foreseen by standards in force;
 Full cleaning every three months of all parts of the counter, wearing the protective gloves foreseen
by standards in force;
 Do not clean the appliance with water jets.
Cleaning the condenser
If present, the counter condensers gather dust and filth and must be cleaned regularly. In standard use
conditions, this operation must be done at least once a month using a hard bristle brush and a vacuum
cleaner. We recommend wearing gloves as the reduced thickness of the fins can cause cuts and abra-
sions. A dirty condenser reduces the counter's performance and increases energy consumption.
In detail: :
 Periodically remove dust from in front of the frontal grate;
 Switch-off the machine and disconnect the power supply cable before performing this operation;
 Access the condenser by loosening the clamping screw of the frontal grate;
 Slide the frontal protective grate to the right;
 Clean the condenser with a jet of air or dry brush and eliminate, with vertical movements, the dust
and fluff deposited on the fins;
 Slide the frontal grate to the left, fixing it with the previously removed screw and power the machine
again.
ATTENTION
During all maintenance and cleaning operations of the counter, use the specific personal protective
equipment, provided by the safety standards in force.

PRECAUTIONS FOR USE AND MINOR MAINTENANCE
Before starting any cleaning, maintenance or parts replacement, even if not electrical, make sure that
electric power is disconnected and/or open the omnipolar power isolator.
Any technical assistance and extraordinary maintenance must only be carried out by qualified technical
personnel.
ATTENTION: when the appliance is no longer working or usable, do not dispose of it in com-
mon waste disposal centres, but contact specific waste collection facilities for the recovery of
materials and substances harmful for the environment.
Loading products for display
Height of Load
Food products preserved within the load limit are appropriately refrigerated. Those preserved beyond
the load limit cannot be appropriately refrigerated and impair the circulation of air, thus jeopardising
operation of the counter and deterioration of all the food products. Also remember that products must
not cover the air inlet for the counter to operate properly.
A refrigerated display counter is not intended to chill perishable food products but rather to keep them
at the temperature at which they were introduced. Food products warmer than that specified for the
counter should not be placed in a refrigerated counter.
Do not leave refrigerated food products on pallets or similar structures inside the shop longer than that
strictly necessary for transport and loading.
Do not overload the counter: this is the most common error which can cause secondary defects, such
as the anomalous formation of frost thus blocking the evaporator and even causing the complete stop-
page of the counter. The even distribution of the goods without leaving empty spots guarantees the
best operation of the counter. It is good practice to rotate the stock when loading the counters with
new products. The older products must be the ones closest to the customers so they are sold first.
N.B.: Counter operation is guaranteed in the climate conditions indicated on the serial number plate
and according to standards ISO 23953-2 if loaded evenly and not beyond the conforming loading line
on each counter.

EMERGENCY SITUATIONS
1. The counter does not start or switches off.
 Check whether there is an electrical blackout in progress;
 Check that the main wall switch is on.
If the electrical interruption does not depend on the above-mentioned reasons, immediately contact
the closest service centre and fully empty the counter, placing the removed products in cold rooms or
in other equipment capable of preserving them.
2. The counter temperature is too low.
 Check that the counter is not loaded beyond the recommended level and that the air vents are
not obstructed;
 Start a forced defrost and clean the counter (following safety measures) to then resume standard
operation;
 Make sure that the counter is not near heat sources and/or air draughts which could hinder
proper operation;
 Should malfunctioning persist, immediately contact the closest service centre.
3. The counter makes too much noise.
 Check that the screws and nuts are fastened all the way.
 Using a level, check that the counter is level.
Should the noise persist, immediately contact the closest service centre.
4. Gas Leak or Fire.
The refrigerant circuit must not be damaged to prevent leaks into the environment. If the gas comes
into contact with the air, there is a risk of fire in the presence of a suitable trigger such as an open
flame or sparks caused by electrical equipment.
For this reason components have been adapted to prevent these risks and when they need to be re-
placed, original components which have been approved for the specific use must be requested.
If servicing due to a breakdown or malfunction, qualified personnel must always be contacted to as-
sess and perform the type of procedure required in compliance with statutory safety regulations for
this type of gas.
The equipment needed for the procedures must comply with the same requirements as the compo-
nents of the system, thus avoiding electrical equipment and flames in the presence of flammable
gases.
For specific procedures related to emptying and loading the system, proceed with equipment suitable
for
the type of gas (vacuum pump, leak detector, etc.) and in any case avoid the presence of flammables
in the premises and in particular contact with flames or sparks.
5. Other particular situations.
 Metal parts must be handled with care to avoid possible and not unlikely abrasions and/or cuts as
well as possible crushing.
 Removing the bottom surfaces exposes the evaporator and motor fans with the ensuing danger
that this could cause.
