Warning: Never remove the protections or covers that require tools to be removed. Never, under any circumstances,
remove the cover on the electronic panel.
Warning: Never load the unit excessively. Never stand on the cabinet.
Warning: Never try to remove any ice (that may build up) with sharp metal objects.
Warning: The refrigerating circuit does not alter the chemical composition of the water resulting from defrosting. This
comes exclusively from the steam contained in the air circulating inside the unit. In any case, this water should always be
disposed of down the drain or sent to a water purification plant in line with current local regulations.
Warning: Any use of the unit not explicitly mentioned in this manual should be considered dangerous and the
Manufacturer cannot be held liable for any damage resulting from improper, incorrect or unreasonable use.
Warning: Do not damage the refrigerant circuit (IEC60335-2-89:2002 and changes).
Warning: Do not use electrical appliances inside the food storage compartments of the appliance, unless they are of the
type recommended by the manufacturer (IEC60335-2-89:2002 and changes).
Warning: This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use
of the appliance by a person responsible for their safety.
Warning: Children should be supervised to ensure that they do not play with the appliance.
Warning: Do not store explosive substances such as aerosol cans with a flammable propellant in this appliance.
9 - Defrosting of the unit and evaporation of any condensation
The defrosting cycle is indispensable for the refrigerating display unit to work properly and is controlled by the electronic
control. This uses armoured resistances on the evaporator to stop the electric condenser temporarily and so allow for 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
for both BT and TN upper section CETUS versions.
Regularly check the efficiency of the automatic defrosting cycle; if there are problems, call an expert technician.
The "plug-in" units have an automatic evaporation system for defrosting water. It's 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.
Warning: Do not use electrical appliances inside the food storage compartments of the appliance, unless they are of the
type recommended by the manufacturer (IEC60335-2-89:2002 and changes).
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: Other maintenance operations, (not described herein) including replacement of lamps with lamps of the same
model, have to be commissioned to authorised centres of assistance or qualified personnel.
Clean the condenser once a month by removing the protection grid (see FIG. 15 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. Ix 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!
In the CETUS BT-TN versions (where the armoured defrosting resistance is an optional accessory), the evaporator in the
top section could become covered with ice after long periods of use, thus preventing the unit from working at full
efficiency. The cabinet should be cleaned every three months, following these rules: A) unplug and empty the cabinet
completely. B) wait for any ice in the evaporator fins in the top section to melt away C) 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 (top and bottom sections) 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 doesn't start:
- Check there isn't a black-out.
- Check the unit is plugged in properly.
- Check the switch fitted above the plug (if any) is flipped.
If none of the above are responsible for the problem, call 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:
