Wels-WelsR290
English
Tell the operator where the switch is so that it can be reached quickly in an
EMERGENCY.
To guarantee correct operation, the maximum voltage variation must be between +/
- 6% of the nominal value.
Check that the power line has appropriate section cables, is protected against
overcurrent and dispersions towards earth, in compliance with current standards.
In the event of an interruption to the electricity supply, check that all store electrical
appliances can reboot without causing the overload protections to intervene. If not,
alter the system in order to differentiate between the start-up of the various
devices.
The installer must supply the anchorage devices for all cables in and out of the unit.
Avoid having the casing come into contact with the electrical panel to avoid
electric shocks which could cause injury or death.
Check that the connectors of the illumination (shelves, ceiling, superstructure)
are inserted properly and blocked in their sockets so as to avoid
disconnection during cleaning and maintenance operations which could lead
to electrical shocks harmful to the operator.
The automatic thermomagnetic switch should be designed so as not to open the
neutral circuit without simultaneously opening the phases. In any case, the opening
distance for the contacts must be at least 3mm.
14. Start-up, temperature control and adjustment
- specialised technician -
The refrigeration temperature is controlled by a mechanical thermometer (Rif. 9)
located on the suction sheet or the display of the thermometer/thermostat (optional)
located on the lower part of the cabinet (Rif. 10).
Normally the controller is set in the factory during testing, but it is possible to alter the
programming. To do so, please refer to the instructions given by the control device
manufacturer.

15.Filling the unit - qualified operator -

To refill the unit, you must comply with some important rules:
arrange the goods in such a way that the maximum load line is never exceeded,
exceeding this limit can prevent proper air circulation (Rif. 11), causing the
temperature of the goods to rise and ice to form on the evaporator.
the arrangement of goods, without leaving empty areas, guarantees optimum unit
function;
arrange the goods in a way that does not interfere with the circulation of the
refrigerated air
The refrigeration unit is designed to maintain the temperature of the product
displayed and not to lower it. Food products must only be introduced if already
cooled to their respective storage temperatures. DO NOT introduce products
that have been heated.
We recommend first using up the goods that have been stored in the unit the
longest, before adding new arrivals (food stock rotation);

16.Defrost and water draining

Wels cabinets are equipped with off-cycle defrosting (interrupting the refrigeration
cycle). During the defrosting stage, the temperature of the products displayed will
increase, though not beyond the limits indicated by Law, and at the end of the defrost
stage the system will rapidly return to the working temperature.

16_1.Water discharge:

The defrost water is collected in a specific drain and taken to a basin at the bottom of
