GENERAL FEATURES
Madeira is a plug-in refrigerated counter for the display and sale of meat, cold cuts, dairy products, fruit
and vegetables with ISO 23953-2 class 3 climate operating conditions.
The maximum depth of the counter when using 450mm shelves is equal to 850mm and is available in
937, 1250, 1875 and 2500 mm lengths. In addition, it is available in Eco Madeira where a sliding door is
provided that allows good energy savings.
All wall counters in the Madeira range are, furthermore, available in plug-in and remote versions. The
plug-in wall counter is equipped with a compressor and begins operation as soon as the plug is con-
nected to the mains supply, while the counter in the remote version requires connection to the central
refrigerant.

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 the front grate. Clean the condenser with a brush every month;
 To access, slide the painted strip upwards Fig. 1b;
 Rotate the aluminium profile until it is released and remove it from the position Fig. 1c, 1d;
 Remove the screws and cover Fig. 1e;
 Clean the condenser Fig. 1g;
 Replace the condenser cover fastening it with the previously removed screw and reattach the
painted strip and aluminium profile.

WARNINGS
Installation recommendations
 Qualified technical personnel must perform installation and maintenance of this appliance;
 Correct positioning of the counter;
 Check that the mains voltage corresponds to that provided on the identification plate.
 This equipment may not be used in the open air and cannot be exposed to rain.
 Connect the appliance to an efficient earthing system.
 Installation and the electrical connection must be performed in compliance with national and local
standards in force.
 For the replacement of the cable and plug use only original factory spare parts.
 Connect the power cable to a plug that is easily accessible even after the counter is positioned.
 Isolate the power circuit upstream by means of an omnipolar circuit breaker switch with a minimum
contact opening of 3 mm.
ATTENTION: The arrangement and amount of products must not exceed the load limit. We also rec-
ommend making sure that the full load is not excessive for the structure of the counter. The following
are the approximate capacity values of the shelves. Respect these indications as much as possible.
N.B.: it is important that the full load of 350 Kg is not exceeded for a 1250 mm module.

General recommendations
To be read before using the counter.
 This manual forms an integral part of the product and must be stored with the equipment to facili-
tate rapid consultation.
 The adjuster must not be used with other functions other than those described below, specifically it
can not be used as a safety device.
 Before proceeding check the application limits.
Safety precautions.
 Before connecting the counter ensure that the supply voltage is as required.
 Do not expose the unit to water or humidity: use the counter only within the limits of operation pro-
vided for.
 Attention: before carrying out any kind of maintenance remove electric connections from the
counter.
 The electric panel must never be opened.
 If malfunction or failure occurs, contact qualified staff for analysis and repair.
Adjustment
Compressor
The compressor's relay is enabled to maintain a defined temperature fixed from the set point. The hys-
teresis Hy is automatically added to the set point. If the temperature increases and reaches the set
point plus hysteresis the compressor is started and then turned off when the temperature reaches the
set point value. (refer to figure)
In case of probe fault, compressor on and off are governed by time through the parameters Con and
COF.
Defrosting
There are two defrost modes via the parameter tdF:
- tdF = EL: defrosting with the electrical resistance (the compressor is switched off);
- tdF = in hot gas defrost (the compressor remains on).
Through the IdF parameter the interval between defrosting cycles with MdF its maximum duration,
with Con P2P the second probe is enabled (defrosting end and temperature) or it disables it (end of
timed defrost).
Once defrosting ends dripping time starts, manageable through the Fdt parameter.
Synchronised defrosting
If the digital entry is set with i1F = dEF defrosting would be synchronised. When any network tool re-
quests defrosting it enables its relay and closes all the digital entrances connected. When it ends its
defrosting it opens the relay, leaving the line free and remains paused until the digital entrance is
opened. It is opened only when the last network device has finished defrosting.

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.

ELECTRIC COMPONENTS
Lighting
For that which regards counter lighting, remember to switch the lights off as soon as possible to save
energy.
Furthermore the counters are equipped with electronic reactors which, if operating conditions are not
appropriate, can trip switching off the lights connected to them. To restore correct functioning, just
switch the counter off and back on.
Electric panels
The following are the different types of electric controllers belonging to the panels with which the
counter can be configured. Also remember that the product will only have one of the available configu-
rations.
ATTENTION: For further information on the chosen instrument, consult the specific manual of the de-
vice supplied together with the counter (see pag. 17). Also pay close attention to consult the technical
sheet of the controller actually installed on your counter.
