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.
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.
Remove all goods from the refrigerated unit and keep them in a
fridge or in a refrigerated ambient suitable for their preservation.
Carefully and thoroughly clean the display surface, the glasses,
the aluminium profiles, the door gaskets (if presents) with specific
cleaners for any surface.
PROHIBITION
Do not use acid and alkaline detergents, chemical / organic
solvents, unknown chemical composition detergents.
During the maintenance and cleaning it is forbidden to use
abrasive substances and/or sharp tools which can damage
the unit (fig. N).
After every cleaning operation it is necessary to rinse with warm
water and dry the unit with a soft and clean cloth.
Clean the condenser, after having removed the cover grid (fig.
O), with a dry paint brush (do not use iron brushes - fig. N) or a
vacuum cleaner, removing all dust and possible deposits on the fins.
ATTENTION
During the maintenance and cleaning pay attention not to
bend or damage the fins and the whole refrigerating unit.
Never neglect this operation, as it is basic for the good working of
the unit and to avoid possible breakings. When you have finished
this operation, fit the cover grid in its original position.
When the cleaning operation is over, make sure that everything
is clean and dry before connecting the equipment to the power
supply again. When the unit reaches the correct working
temperature, it is possible to reload it. In case of long absences (i.e.
holidays etc.) the unit has to be unplugged, emptied completely,
cleaned and dried. Make sure to leave the doors open to prevent
bad smells.
A correct maintenance of the equipment can considerably prolong
its life.
19) TECHNICAL ASSISTANCE (servicing)
ATTENTION
If the equipment does not run properly or does not work
at all, in your own interest before calling for servicing, we
suggest to check the following points:
- if the plug is well inserted in the socket;
- if the power reaches the socket to which the equipment is
connected;
- if the thermostat is set as recommended;
- if the network voltage is the same as requested for the
equipment (+-6%);
- if the evaporator is covered with ice (in this case proceed
as indicated at paragraph 16);
- if the condenser is clean (paragraph 18);
- if there are air draughts, if the cabinet is installed in the
correct position (see paragraph 9) and if the ambient tem-
perature is as indicated (see paragraph 7).

20) REPLACEMENT OF LAMPS

The replacement and the substitution of lamps must be made by
qualified technician and when the unit is disconnected from the
power net.
Before replacing the lamp disconnect the equipment by the general
power supply. During the whole replacement operation use proper
working gloves.

21) EMERGENCY SITUATIONS

Devices to be used in case of fire: powder-extinguishers or liquid-
extinguishers complying with the current legislation.

22) DISMANTLING THE UNIT

OBLIGATION
The unit must be disposed of in accordance with your coun-
try's waste management legislation.
ATTENTION
This equipment contains HFC, a coolant with a high green-
house effect potential (GWP).
The components of the refrigeration circuit must never be
cut and/or separated. They must be returned intact to a
specialized centre for the refrigerant recovery.
This appliance is hermetically sealed and the coolant load is
less than 3 kg.
OBLIGATION
IN CASE OF REQUEST FOR SERVICE, CONTROL
AND/OR REPLACEMENTS YOU WILL HAVE TO
CONTACT THE SUPPLIER WHERE THE CABI-
