or interlacement with other cables, trample on, crushing,
stretching.
A wrong installation could cause damages to people,
animals or things, for which the manufacturer cannot be
deemed responsible.
12) FIRST CAREFUL CLEANING
OBLIGATION
IMPORTANT – DURING THE WHOLE CLEANING
OPERATION USE WORKING GLOVES OF CLASS
II TO PROTECT YOUR HANDS ALL THE TIME
AND THE PERSONAL PROTECTIVE EQUIPMENT
ACCORDING TO THE LAW OF YOUR COUNTRY.
Before switching on the unit, take away the protective film that
covers some external and internal parts of the cabinet (for example
the display surface, etc.). Clean the refrigerated cabinet thoroughly,
both inside and outside, using warm water (max. 30°C) and a
solution of bicarbonate of soda (1 tea spoon every 2 liters) or
white vinegar. Carefully dry the unit with a soft cloth.
PROHIBITION
During the cleaning operation it is forbidden:
- To use detergent products, metal pads or abrasive sub-
stances that could damage the aesthetic appearance of the
equipment.
- To use sharp objects (any damage resulting from the use
of these objects will not be covered by warranty).
- To spray water directly on the electric parts and to wet
the electrical parts (fans, lighting, electrical cables, etc.).
- To wash the refrigerated cabinet with water jets.
Once the cleaning is finished, switch the unit on through the
ON/OFF switch and wait until the cabinet reaches the proper
temperature for the products that have to be displayed. It will take
approx. 3 hours for the cabinet to reach the proper temperature.
The products to be displayed will have to be already cold according
to the cabinet temperature.
13) LOADING INDICATIONS
This refrigerated cabinet is proper for the preservation of
foodstuffs if the following rules are respected:
a) place the foodstuffs on the display area in such a way as to never
exceed the loading line, so that the correct air circulation is not
prevented (fig. L);
ATTENTION
The loading line is indicated by a label applied on the glass
(fig. L). In case the label is damaged or replaced, the loading
line has to be indicated at 15 cm.
b) place the products in a regular way, without leaving empty
spaces;
c) make a correct rotation of the foodstuffs, taking away first the
products that have been staying inside the cabinet for longer time.
Avoid exposing fresh meat for more than 4 hours.
14) CONTROL DEVICES (Fig. M)
a – On/Off switch
b – Light
c – To switch on or off the anti-mist heater (optional)
d – Digital controller
e – Socket (optional)
15) DIGITAL CONTROLLER
The thermostat is already set at the factory. In case the
temperature is altered, the manufacturer will not take any
responsibility. Any modification will have to be made by qualified
people.
16) TEMPERATURE
The thermostat regulates the temperature into the equipment and
the working temperature is already preset at the factory.
A lower performance must be expected from the refrigerated unit

when:
- the equipment is set on the lowest temperature
- the equipment is positioned in an ambient with higher
temperature or relative humidity than above indicated
- the amount of displayed goods exceeds the maximum
recommended and the proper air circulation is prevented.
In those cases the goods are kept at higher temperatures, the
refrigerating unit has to run non-stop and ice may form on the
evaporator. It is necessary therefore to turn the equipment off to
allow the complete melting of the ice. During this phase do not
use any kind of sharp object to make the melting of the ice quicker,
because you could cause big damages to the equipment. Once the
ice is completely melted, switch the equipment on through the
ON/OFF switch (as indicated in paragraph 12).
17) DEFROSTING
The defrosting takes place automatically during the running of the
unit. The defrosting cycles are 6 a day and last for about 25’ each.
During the defrosting phase the temperature of the unit could be
altered, but when this cycle is over, in a short time the working
temperature will return to normal.
OBLIGATION
The water from defrost is collected in a drip tray that has
to be emptied manually when necessary. The plastic tray is
supplied with the counter and has to be placed below the
drain on the right side seen from the service side, as shown
in picture P.
It is possible to order the counter with electric evaporation
(optional).
18) PERIODICAL MAINTENANCE AND
CLEANING
We suggest to carry out a daily/weekly cleaning of the external
parts of the equipment and a monthly thorough cleaning of the
internal parts of the refrigerated cabinet for the good working, the
good preservation of the food and the aesthetics preservation of
the equipment. The cleaning has to be made by qualified people,
who should know the procedure described in this paragraph.
Attention! Before starting any cleaning operation it is
necessary to turn off the equipment by the on/off red
switch and to unplug or disconnect the equipment by the general
power security switch of your shop.
