1 - Description of the unit
The GENIUS 2 range of display units are built in modules with a useful internal length of 550 mm (MODEL 63), 620 mm
(MODEL 70), 937 mm (MODEL 100), 1250 mm (MODEL 135) and 1875 mm (MODEL 200) and can be in two different
heights: 1250 mm (H125) or 1450 mm (H145). All these cabinets are multiplexable and are equipped with an integral
condensing unit, with fan assisted refrigeration. FIG. 1 on page 1 clearly shows the general look and dimensions of these
units.
2 - Handling the unit
The unit comes with wooden slides (wooden crating available on request) to allow handling by a forklift truck. Only
authorised technicians should handle the unit.
FIG. 2 on page 1 shows the weight of the units in the different lengths and relevant lifting points.
3 - Receipt and storage
On delivery, check that the unit has not 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, front risers, etc).
Remove the brackets and the pallet (see FIG. 4 on page 2) and then remove the transparent protection around the unit.
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.
Oscartielle cannot be held liable for any damage caused to the unit by mishandling and inaccurate storage.
4 - Installation and environmental conditions
The unit must sit on a perfectly levelled floor. When fully loaded, the display unit should not vibrate (see FIG. 5 on page
2). The efficiency of the unit may be compromised if this is not 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 on page 2).
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 on page 4). Do not
place objects in front of the condenser protection grid, as this could compromise the efficiency of the refrigerated display
unit (see FIG. 6a-6b on page 2). 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 at page 7-8.
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 cutoff 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.1
on page 3 (climatic class 3 = 25°C RH60%; climatic class 4 = 30°C, RH55%). The "plug-in" units are supplied already
fitted with a 2,5 m. cable and plug (see FIG. 7 on page 2) and so the unit must not be installed more than 2,5 m. from the
nearest wall socket. The display unit must be connected to its own fixed current socket (i.e. without extension leads or
multiple plugs). The cable should be fully extended and located where it is 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.
Warning
: Follow the Manufacturer's instructions to install the unit, using qualified personnel and in compliance with the
electrical regulations for the specific country (electrical safety standards and laws, accident and fire prevention laws, EC
directives). Incorrect installation may cause injury and damage; the Manufacturer cannot be held liable for this.
The unit must be earthed. The Manufacturer cannot be held liable for any damage or injury should this safety regulation
be ignored. If the unit is to be installed far from the electrical sockets, suitable electrical connections are needed and
these must comply with the prevailing standards. The use of adapter plugs is strictly prohibited.
The Manufacturer
cannot be held liable for any damage or injury arising from incorrect installation
.
