Oscartielle Cetus BT/TN 137 Mode D'emploi page 15

ENGLISH
1 - Description of the unit
The CETUS combined display unit is available in two versions: the BT-BT (BT deep-freezer and BT top section) and the
BT-TN (BT deep-freezer and TN top section). These versions are supplied as single, non-multiplexible units with 1250
mm (MODEL 1347) or 1875 mm (MODEL 200) internal useful length. CETUS display units are equipped with an integral
condensing unit with static refrigeration in the basin and ventilated refrigeration in the superstructure. FIG. 1 on page 1
clearly shows the general shape and dimensions of these units.
2 - Handling the unit
The unit comes with wooden slides (wooden crating available on request) allowing handling by a forklift truck. Only
authorised technicians should handle the unit.
FIG. 2 on page 1 shows the weight of the units in their various lengths and their lifting points.
3 - Receipt and storage
On delivery, check that the unit hasn't been damaged during transit. 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 atmospheric agents 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 (Grilles, Price Indicators, Dividers, 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 handles!
Warning: Inform the Manufacturer immediately if the goods arrive damaged: any delay in doing so relieves the
Manufacturer of all liability.
Any damage to the cabinet occurring during shipment and storage may not be attributed to the manufacturer.
4 - Installation and environmental conditions
The unit must sit on a perfectly leveled 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 isn't perfectly leveled!
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 3). 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 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 get around 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 5.
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.1
on page 3.
The plug-in cabinets are are supplied already fitted with a cable m. 2,5 long without plug (see FIG. 7 on page 2).
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, protected from accidental hits and located where it can not be caught or trod upon. It
must be 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
