system is by hot gas. The number of defrosts cycles set in the factory is 4 cycles in 24 hours. Check periodically to make
sure the cabinets are defrosted automatically and in case of any malfunction call an expert.
Dorado cabinets are equipped with an automatic evaporation system which eliminates the defrost water. At least once a
month check the level in the evaporation tray on the side of the motor compartment (this should be done when the
cabinet is off).
Caution: any adjustments or alterations should only be made by the service personnel.
Attention: Ne pas utiliser dispositifs mécaniques pour accélérer le dégivrage différent de les conseillé du fabricant
(IEC60335-2-89 :2002 et variantes).
Caution - Note for the proper working of the cabinet in ice cream version: Every 48 hours it is necessary to switch
off the cabinet for at least 8 hours, in order to allow the melting of the ice on the evaporators.
11 - Cleaning the cabinet
Caution: before cleaning the cabinet unplug it from the power mains. Periodically clean the cabinet with mild detergent
and dry with a soft cloth. Do not use inflammable or abrasive products. Do not clean the cabinet with direct jets of water.
When you clean the evaporator wear gloves to protect the hands from possible cuts and from direct contact with cold
surfaces.
Caution: plug the cabinet to the power mains only after having checked that the cleaned components are dry. Load the
cabinet following the instructions at Par. 6.
12 – Maintenance of the cabinet
Routine maintenance:
The cabinet is equipped with a battery-operated digital thermometer with liquid crystal display inside the basin (FIG. 17
page 5). If the thermometer does not display the temperature because of a dead battery, replace it with a new one of the
same voltage. Always dispose of dead batteries at authorized disposal centers. (Batteries should never be disposed of
with ordinary waste).
Replacement of the battery: using a screwdriver pry up one side of the thermometer to raise it and take it out of its
housing (FIG. 18A page 5). The battery housing is on the back of the thermometer; twist the cover counterclockwise and
remove the dead battery (FIG. 18B page 5).
Special maintenance:
Clean the condenser once a month (plug-in version only), after removing the protective grid on the rear of the cabinet
(FIG. 19 page 5). Use a brush with stiff bristles (not metal) or a vacuum device, which is even better, to eliminate any
deposits of dust between the fins. When you clean the condenser wear gloves to protect the hands from possible cuts.
After cleaning, replace the grid previously removed. Leaving the condenser dirty for long periods leads to higher energy
consumption and poor performance of the cabinet.
We recommend having a refrigerator expert check the cabinet completely once a year.
Ice may form on the evaporator after long periods of use preventing proper operation. Every three months, clean the
cabinet thoroughly: unplug it and empty it completely. Wait for the ice on the fins of the evaporator to dissolve completely
and clean all parts of the cabinet as described in Par. 10 (before switching it back on, make sure it is completely dry).
Caution: before cleaning the cabinet unplug it from the power mains.
Caution: 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.
13 - Emergency situations
Caution: if the cabinet should stop or fail to start:
- Make sure there is not a situation of electrical black-out.
- Make sure the switch on the control panel has been pressed.
If the stoppage is not due to one of these causes, call the nearest service center and empty the cabinet. Place the
products in cold rooms designed for maintenance and storage.
Caution: if the cabinet does not chill sufficiently
- Make sure the condenser is clean and capable of performing its heat exchange function. If not, read Par. 12.
- Make sure the cabinet is correctly loaded and that the air vents are unobstructed. If not read Par. 4.
- Make sure the evaporator is not covered with ice. If not read Par. 12.
- Make sure the cabinet is not close to a draft or heat source (see Par. 4).
- Make sure the cabinet is level and the environmental conditions listed in Par. 4 are respected.
If after checking all these things the problem persists, call the nearest service center.
Caution: in case of a gas leak or fire, do not go near the motor compartment. Disconnect power to the cabinet. Do not
use water to extinguish flames. Use only a dry fire extinguisher.
