10 - Defrosting cabinet and evaporation of condensation
The defrost cycle, which is indispensable for proper operation of the refrigerated cabinet, is under the control of the
electronic device, that temporarily stops the compressor and allows the evaporator to eliminate any accumulated ice. This
operation can be simplified by introducing armored heating elements that help the ice on the evaporator to melt when the
defrost cycle is on. These heating elements are optional and are supplied on request. The number of defrost cycles is set
in the factory. Standard setup is 4 cycles every 24 hours for off-cycle defrosting and 4 x 25 minute cycles every 24 hours
for electric defrosting. Check periodically to make sure the cabinets are defrosted automatically and in case of any
malfunction call an expert.
Plug-in cabinets, except for Marte 2 model for fish, are equipped with an automatic evaporation system which eliminates
the defrost water. At least once a month check the level in the evaporator tray placed on the condensing unit basement
(this should be done with the cabinet off).
For cabinets with remote unit and for model Marte 2 for fish it is necessary to make a water outlet in the ground with pipe
diameter 40 mm.
Caution: any adjustments or alterations should only be made by the service personnel.
Caution: 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 and changes).
11 - Cleaning the cabinet
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.
Caution: before cleaning the cabinet unplug it from the power mains.
12 – Maintenance of the cabinet
Routine maintenance:
The cabinet is equipped with a battery-operated digital thermometer with liquid crystal display inside the basin. 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.18). The battery housing is on the back of the thermometer; twist the cover counterclockwise and remove
the dead battery (FIG.19). Special maintenance:
For cabinets with internal unit, clean the condenser once a month, after removing the protective grid on the rear of the
cabinet (FIG. 20). 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. 11 (before switching it back on, make sure it is completely dry).
Caution: before cleaning the cabinet unplug it from the power mains.
Caution: 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. 8.
- 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.
14 - Additional instructions for MARTE 2TC
The makes MARTE 2 TC use of warming plate (PW) or bain-marie (BM) heating system.
The thermostat is set at +75°C in the factory. Tampering with the factory settings relieves the manufacturer of any liability.
