1 - Description of the unit
The MINOR2000 line of display cabinets are built-in units with a usable internal length of 620mm (MODEL 70), 900mm
(MODEL 100), 1188mm (MODEL 130), 1800mm (MODEL 190), 2376mm (MODEL 250), in the versions for deli/dairy
products, packaged fruit/vegetables and packaged meats. All these cabinets can be multiplexed and are equipped with a
built-in condensing unit, with fan assisted cooling. FIG. 1 illustrates the general appearance and dimensions of these units
in detail.
2 - Handling the unit
This furniture item has plastic feet (FIG. 4.1) or wooden pallets (FIG. 4.2) for cage packaging (on request) to allow
handling by a forklift truck. Only authorised technicians should handle the unit.
TAB.1 and FIG. 2 shows the weight of the units in the different lengths and relevant lifting points.
3 - Receipt and storage
On delivery, check that the unit hasn't been damaged during transport. Check the condition of the packaging: if the
packaging is damaged, check the contents in the presence of the carrier.
For storage, make sure that the unit is protected against the weather and stored at a temperature between -25°C and
+55°C; 30-95% relative humidity.
Take special care when unpacking the unit, as the packaging contains various parts and/or accessories needed to
complete the display unit (spacers, raised edges, etc).
Remove the plastic feet from the unit (FIG. 4.1) or wooden pallets (FIG. 4.2) and remove the transparent perimeter
protection.
Place the display unit exactly where you want to install it. Move the unit properly:
never drag by its sides!
Warning:
Inform the Manufacturer immediately if the unit arrives damaged. Any delay in doing so relieves the
Manufacturer of all liability.
The Manufacturer is not liable for any damage to the unit during handling and storage.
4 - Installation and environmental conditions
Disconnect the cabinet from the square and from the packaging and screw the adjustable feet. (Fig. 4.2.B).
The unit must sit on a perfectly levelled floor. When fully loaded, the display unit should not vibrate (see FIG. 5). The
efficiency of the unit may be compromised if this isn't perfectly level!
The display unit must never be placed in areas where explosive gas substances are used.
The unit should not be left outdoors or exposed to the rain (see FIG. 3).
The performance of the cabinet refers (according to the international standard
EN ISO 23953-1/2
) to environmental
climatic class 3 which consists of a room temperature of 25°C with relative humidity of 60%.
Sufficient space must be provided to guarantee good air circulation for the condenser (see FIG. 9). Do not place objects
in front of the condenser protection grid, as this could compromise the efficiency of the refrigerated display unit (see
FIG.6). The performance will be less than expected if the environmental conditions differ from those foreseen, or the
display units are exposed to air flows of more than 0.2m/sec or heat radiation.
To avoid this problem, the User should send the Manufacturer details of the environmental conditions before finalising the
design of the units, so that the technical parameters and material options can be modified and the installer be informed of
the refrigerating power actually required.
5 - Electrical connections
Important: installation should be made following the manufacturer's instructions, by qualified personnel only, in conformity
with the electric safety regulations in force. Please refer to the electrical diagram on FIG.16.1 and FIG.16.2.
At the input of the supply it is necessary to install an omni-polar magnetothermic/differential device with contact opening
equal to 3 mm and adequate cut-off power.
Warning:
Before connecting the unit to the mains, make sure that the mains voltage corresponds to that indicated on the
serial plate (bearing in mind that the max acceptable variations in voltage are +/-10%). Check that the cable used has the
right cross-section and length to withstand the current and the power absorbed by the combination, as indicated in
TAB.2.1, TAB.2.2.
The plug-in cabinets (except for Minor 2000 L250) are supplied already fitted with a cable m. 2,5 long and a plug (FIG.7).
The plug has to be inserted into a fix socket, without using further extension, multiple outlet or longer cables.
The plug-in cabinets Minor 2000 L250 are are supplied already fitted with a cable m. 2,5 long without plug. Therefore it is
necessary to have an industrial plug (according to standard IEC309 for 16 A) assembled on the supplied cable by
qualified personnel. Then plug into an industrial socket (according to standard IEC309 for 16 A) without using any further
extension, multiple outlet or longer cables.
The cable should be fully extended and located where it's unlikely to hit, caught or trod upon, away from water and other
liquids and heat sources and must not be damaged. In case of breakage of the power cable of the cabinet, it must be
replaced by the manufacturer or by institution in charge of it. The plug must still be accessible even after installing the
unit.
