8. Electric connection (Fig. 12...Fig. 15)
- The cabinet must be protected upstream by means of a thermomagnetic omnipolar automatic switch,
of suitable characteristics, which also works as main knife switch in the line.
- The operator must know the switch position in order for it to be readily accessible in case of
EMERGENCY.
- The electric system must be grounded.
- First of all, make sure that the power supply voltage is the same as that indicated on the nameplate.
- In order to guarantee regular operation, the maximum voltage variation must fall between +/-6% of
the nominal value.
- Make sure the supply line is wired with cables of adequate cross-section, and is protected against
current overload and grounded in conformity with the laws in effect.
- For power supply lines that are longer than 4 - 5 m, increase the cable section accordingly.
- In the event of a power failure, make sure that all the electric appliances in the shop can be re-started
without activating the over-current protections; if not, modify the system so as to differentiate start-up
of the various devices.
- The installer should provide the anchorage for all the cables entering and leaving the cabinet.
- The automatic magnetothermal switch must not open the circuit on neutral without also opening it on the
phases at the same time and, in any case, the opening distance of the contacts must be at least 3 mm.
N.B. All these operation should be performed by specialized technical personnel only.

9. Temperature control (Fig. 6)

The control of refrigerating temperature is carried out using the mechanical thermometer located on
the air intake vent (Rif. 11) or using the electronic CAREL controller (OPTIONAL) Rif. 5.

10.Cabinet loading (Fig. 6)

A number of important rules should be followed in loading the cabinet:
- arrange the goods in a uniform, orderly manner to avoid overloading the shelves (160 kg/m
- arrange the merchandise so that it does not obstruct the flow of chilled air (Fig. 7, Rif. 16 - Rif. 14);
- the arrangement of the goods, without empty spaces, assures the best operation of the cabinet;
- leave approx 30 mm space between the items and the shelf immediately above (Rif. 12);
- we recommend that the first loaded items are consumed first and only then the last loaded ones (item
turnover);
- The max load permitted on the shelves is 160 kg/m
basin;
- The shelves can be inclined in 2 positions: 0°; -10°(Rif. 8).
N.B.On request we can add a third tilt at -20°.
ATTENTION!: Do not load the cabinet top with boxes, packages or other objects (Rif. 9).

11.Defrosting and water discharge (Fig. 10)

The Berlino 3 line of refrigerated cabinets, depending on the model, is equipped with one of the fol-
lowing defrosting systems:
- Off-cycle defrosting (with stoppage of the refrigeration process);
- (OPTIONAL) Electric defrosting (with stoppage of the refrigeration process and use of an armored
electric heating element in the evaporator).
N.B.For the Post Container (PC) model electric defrosting is standard.
To drain the defrosting water follow the procedure below:
- provide a slightly sloping drainage in the floor (Rif. 16);
- install a drain-trap (supplied with the cabinet) between the cabinet draining duct and the floor
connection;
- hermetically seal the water draining area of the floor.
This procedure prevents the risks of bad smell inside the refrigerated cabinet, dispersion of refrigerated
air and possible malfunctioning due to humidity.
N.B.Periodically have a qualified installer check that the hydraulic connections are in a perfect
state.

12.Illumination (Fig. 6)

The internal lighting of the cabinet is provided by fluorescent lights.
