Oscartielle MERAK 135 Mode D'emploi page 16

1 - Description of cabinet
The cabinets of the MERAK line are built in units with a usable internal length of 1250 mm (MODEL 135), 1875 mm
(MODEL 200), 2500 mm (MODEL 260), with end panels 40 mm thick and they are not multiplexable.
The cabinets are available in static and fan assisted versions, and can be completed with a wide range of accessories
and optionals.
The general features and dimensions are clearly illustrated in FIG. 1 on page 1.
2 - Transport of the unit
The cabinets are provided with wooden runners (or packed in cages on request) so as to be movable by means of a
forklift. The insertion points of the forks for handling are shown in FIG. 2 on page 1. The weights of the cabinets in the
different lengths are listed in TAB. 1 on page 1.
Important: handling should only be done by authorized personnel.
3 - Arrival and storage
On delivery, make sure the cabinet has not been damaged, and check the conditions of the packing. If it shows any
damage, check the contents in the presence of the carrier. The cabinet should be protected from atmospheric agents,
and stored at a temperature between -25°C and +55°C, with relative humidity between 30% and 95%.
Disconnect the cabinet from the fastening brackets and remove the padding around it. Position the cabinet exactly where
you plan to install it. Move the cabinet carefully, never pull it by the end walls!
Unpack the cabinet with care because the glass parts and all the accessories are packed inside it.
Important: if the goods are delivered damaged, notify the manufacturer as once: any delay in reporting damage will
relieve 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
For correct operation, make sure the cabinet is absolutely levelled and, if necessary, adjust it by screwing or unscrewing
the feet (FIG. 3 page 2).
Do not install the cabinet in rooms where there are explosive gasses.
Do not use the cabinet out of doors or expose it to rain (FIG. 4 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%. If the environmental
conditions are different, or the cabinets are exposed to drafts in excess of 0.2m/sec., or heat radiations, the user must
accept inferior performance. It is possible to overcome this problem by informing the manufacturer of the effective
environmental conditions prior to drawing up the final project, in order to make possible alterations to the technical
optionals of the cabinet.
Adequate space should be provided in front (client side), and in back (operator side) of the cabinet to permit maintenance
and cooling of the condenser (FIG. 5 page 2). In case of a rear platform, we suggest providing a removable part near the
control panel to facilitate maintenance.
5 - Assembly of cabinet
The operations of assembly of the cabinet should be carried out exclusively by authorized personnel.
Assemble the superstructure proceeding according to the following sequence:
- Position the glass sides in their housings and fasten them by screwing the plastic glass holders into the thermoformed
end walls (FIG. 6 page 2).
- Fit the end covers in stainless steel on the canopy (FIG. 7 page 2).
- Screw the canopy, with the end covers already installed, to the glass sides (FIG. 8 page 3).
- In the fan assisted version assemble the anti-mist glass (FIG. 9 page 3)
- Put the front glass in the proper housing (FIG.10 page 3)
- Finish the assembling of the cabinet by applying the bottom plate on the front (FIG. 11 page 3) and the top glass shelf
(FIG. 12 page 3).
The interior surfaces (bottom shelves, air intake and delivery strips, etc.) as well as the external surfaces (front plinth and
counter in stainless steel, etc.) are covered with a protective film that has to be removed before starting to use the
cabinet.
6 - Electric connection
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 6.
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.
Caution: Before connecting the cabinet to the power mains make sure the supply voltage corresponds to the rating on
the serial number plate (consider that the maximum voltage variations admissible are +/- 10%). Make sure the electric
connection is made with cables of a diameter and length capable of withstanding the power and current absorbed by the
