To ensure normal operation, the maximum variation of the voltage must range
between +/- 6% of the nominal value.
Check that the power supply line has wires with an appropriate diameter, that it is
protected against overcurrents, and that the leakages to ground are in compliance
to the norms in force.
If the electrical power supply is interrupted, check that all the electrical devices of
the store can restart without triggering the intervention of the overload protections;
on the contrary, modify the system so as to differentiate activation of the various
devices.
If the power supply cable is faulty or ruined, it must be replaced by the
manufacturer or authority chosen by the same.
The installer must provide the anchoring devices for all the wires in input and outpout
to/from the cabinet.
Check that the connections of the various lighting devices (floors, roof,
superstructure) are properly inserted and locked into their respective sockets,
so as to prevent disconnections during cleaning and maintenance operations
that may cause electrical shocks harmful to the operator.
The automatic magneto-thermal switch must be such that it does not open the circuit
on the neutral, without simultaneously opening on the phases and, at any rate, the
distance between the opening of the contacts must be at leat 3 mm.
12.Position of the probes (Rif. 26) - specialized technician -
The probes are already assembled in the cabinet and are:
Sout Green air inlet control probe
Sdef Black defrost end thermal switch control probe
Sin Yellow suction air control probe
Temperature probe: NTC IP67 .
The Sin-Sout probes must be blocked with Betterman 6-17 code 04355001
terminals and must not be insulated.
The Sdef probe must be fixed in contact with the aluminium fins using the bulb
holder stainless steel spring code 02230134.
13. Start, control, and adjustment of the temperature
Control of the refrigeration temperature is performed via the mechanical thermometer
(Rif. 12) or on the display of the electronic controller (OPTIONAL) (Rif. 11) positioned
on the lower front part of the cabinet. Normally, the controller is programmed in the
factory during the testing phase; in case the programmed setting is changed, refer to
the instructions provided by the manufacturer of the controller.
14.Loading the cabinet - qualified operator -
To stock up the cabinet, certain important rules must be followed:
uniformly and orderly arrange the goods, avoiding to overload the decks (max.
load: 160 kg/m
Arrangement of the goods without empty spots ensure better operation of the
cabinet.
leave approx. 30 mm of air space between the goods and the upper deck (Rif. 15).
