2) Keep internal parts perfectly clean. Internal cleaning entails defrosting, which must be carried out whenever frost
thickness exceeds 5 mm, as it may have negative effects on the performance of the refrigerator. However, the cabi-
net can be defrosted sooner if display purposes recommend it. Defrosting should be accomplished as follows:
a) Empty the cabinet, store its contents in coldrooms or freezers that are adequate for keeping the requisite pre-
servation temperature.
b) Start defrosting as explained in section 8 "Description of controls".
c) Wait until the case reaches ambient temperature and check that no trace of ice remains on the walls. Do not
remove the ice by the use of metal or other sharp tools that may damage the walls.
d) Carefully clean the inside of the case with lukewarm water and mild soap. Then wipe thoroughly with a soft cloth.
e) After having carefully checked that the inside surfaces are perfectly dry (otherwise let them dry on), close the sli-
ders and switch the freezer on again.
f) Allow three hours before loading the products back again.
3) Clean the condenser at least every 30 days with a hard non-metal brush, taking off dust and dirt from between
the fins. To access the condenser it is necessary to disconnect the appliance from the power source and then remo-
ve the ad-hoc front guard by detaching it from the magnets that hold it in place (see fig. 19 on page 17). A dirty
condenser cools imperfectly, so causing waste of energy and poor performance. Wear heavy-duty gloves when
cleaning the condenser.
If you wish to put the cabinet out of service, disconnect it from the power mains and follow the steps above, but
leave the sliding lids open to avoid mouldy odour.
Any maintenance operation not dealt with above, must be carried out by the authorized after-sales service or by
qualified personnel.

10. EMERGENCY SITUATIONS

1) The cabinet will not start or will not keep on working:
• there may be a general blackout;
• the wall master switch may be off;
• The plugs of the equipment may be not properly connected to the power outlet..
If power failure is not due to any of the above causes, call the nearest after-sales service immediately, empty the
cabinet and store the foods in coldrooms or refrigerators that may ensure their preservation temperature.
2) The cabinet will not cool properly
• Check that glass sliders have not been left open or ajar; with the sliders closed the red alarm lamp will go off
as soon as the freezer reaches its temperature setting again.
• Make sure that the cabinet has been filled correctly (that the load limit line has not been exceeded).
• Ensure that frost thickness inside the cabinet does not exceed 5 mm. If it does, defrost the cabinet as explained
in the previous section;
• Make sure that the cabinet is not exposed to sources of heat or draught;
• Check that the products were placed in the freezer at a temperature below -18°C.
• Check that the cabinet is perfectly horizontal by the use of a spirit level. Make certain that ambient conditions
comply with the requirements of page 11;
If failure to cool should is not due to any of the above reasons it it persists on even after the above checks, resort
to the nearest after-sales service.
