9 - Defrosting of the unit and evaporation of condensation water
The defrosting cycle is indispensable for the refrigerating display unit to work properly. It is controlled by a mechanical
thermostat that temporarily stops the electric compressor and allowing the evaporator to get rid of any built-up ice. The
number of defrosting cycles (normally 3 every 24 hours) is set in the factory. Regularly check the efficiency of the automatic
defrosting cycle; if there are problems, call an expert technician.
The GENIUS display units have an automatic evaporation system for defrosting water. It is a good idea to check the level of
the evaporating basin in the motor compartment at least once a month (with the unit switched off).
Warning: Only authorised service personnel are allowed to adjust or modify the unit.
10 - Cleaning the unit
Warning: Unplug at the mains before cleaning.
Clean the unit on a regular basis with neutral soap and then dry with a soft cloth. Never use flammable or abrasive products.
Never clean the unit with direct jets of water. When cleaning the inside of the unit, always wear protective gloves to avoid
touching the cold parts.
Warning: Only plug the unit back in after checking that all parts (extracted or otherwise) are dry. Reload the unit following
the instructions in point 7.
11 – Unit maintenance
Warning: All maintenance operations should be carried out by expert personnel.
Warning: Unplug at the mains before servicing.
Warning: Any maintenance operations not described below (including the replacement of fluorescent lights) should be
carried out by authorised service centres or authorised personnel.
Clean the condenser once a month by removing the protection grid (see FIG. 16 on page 4). Use a stiff bristle brush (not
metallic) or a vacuum cleaner to remove all traces of dust and waste that may have built up between the fins, taking care not
to damage these. Always wear gloves that protect your hands against accidental cuts. Fix back in place all protections after
cleaning.
Letting the condenser run for long periods without cleaning it means higher energy consumption and lower overall
performance of the unit!
The evaporator could become covered with ice after long periods of use, thus preventing the unit from working at full
efficiency. Generally clean the cabinet every three months: unplug and empty completely. Wait for any ice in the evaporator
fins in the top section to melt away and then carefully clean with a soft bristle brush. Again, always wear protective gloves to
avoid cutting your hands. Before plugging the unit in again, always check that all internal parts are completely dry.
We recommend getting the unit serviced once a year by a refrigerator expert or qualified personnel.
12 - Emergencies
Warning: If the unit stops or does not start:
Check there is not a black-out.
-
-
Check the unit is plugged in properly.
Check the switch fitted above the plug (if any) is flipped.
-
If the problem persists despite the above checks, contact your nearest service centre and empty the unit (placing the
products in suitable storage cells to avoid breaking the cold chain).
Warning: If the unit doesn't cool the products enough:
Check that the condenser is clean and capable of exchanging the heat; otherwise, see point 11.
-
Check that the unit has been loaded properly and that the air intake is not blocked; otherwise, see point 7.
-
-
Check that the unit evaporator is not covered with ice; otherwise, see point 11.
-
Check that the unit isn't close to strong air flows or heat sources (see point 4).
Check that the unit is levelled and that the environmental conditions meet those indicated in point 4.
-
If the problem persists despite the above checks, contact your nearest service centre.
Warning: Never approach the motor compartment in the event of leaking gas or a fire. Unplug at the mains. Never use water
to put out any flames, but only dry powder extinguishers. All the materials used to build the unit are fire-proof or self-
extinguishing and non-flammable.
