PU POSE
The devices produced by DORA METAL belong to a group of professional chilling and freezing equipment.
They are intended for short-term storage of foodstuffs at work place.
The devices can be used in restaurants, confectioners' shops, cafés, networks of stores in which it is
necessary to display foodstuffs in a chilled or frozen state allowing maintaining their taste, smell and aesthetic
values.
The temperature adjustment ranges for particular types of devices are specified in the technical data.
The device should be located away from heat sources, in a place not exposed to sunlight.
The devices are not designed for the operation outside the buildings and they cannot
be exposed to the direct effects of adverse weather conditions (snow, rain, sunlight).
The devices are not intended to store drugs, blood plasma, laboratory resources and other
substances and products specified in the directive 2007/47/CE.
The producer does not assume responsibility for any improper use of the device, contrary
to its purpose.
EF IGE ATED SYSTEM OPE ATION
There is one-step, compressor’s refrigerating cycle in the device. The refrigerated system is filled with
an ecological refrigerating medium permitted by the current law regulations (R2 0 or R455A - data included
in the rating plate). An expansion element is a capillary tube.
INTE IO TEMPE ATU E SET-UP
An electronic temperature controller sensor is located on the chamber wall. The controller is programmed
in such a manner that the device achieves an interior temperature specified in the technical data. A method of
required temperature set-up – see p.2 .
STA T-UP P EPA ATION. CLEANING AND MAINTENANCE
The first start-up and daily maintenance may be carried out by the operating personnel, provided that
the below-mentioned recommendations are strictly observed. The producer shall not take responsibility for
any operation carried out on the device without observing the recommendations specified in this user
manual.
Disconnect the device from the power supply system before starting any maintenance works.
The removal of any safety systems is forbidden.
Remove a protective foil before the first start-up. Wash external and internal surfaces with warm water
with an addition of degreasing agent, used for washing kitchen utensils, with a soft cloth in accordance with
a direction of the joint, never by circular movements. The protective foil should be removed slowly to avoid
leaving remains of adhesive. If the adhesive is left, it can be removed by means of proper non-corrosive
solvent – after this operation the surface should be washed out and dried.
In daily cleaning, use neutral soap, window cleaners or 0%-degradable liquid detergent (to minimize
amounts of contaminants disposed to the surrounding environment) and a soft cloth, always in accordance
with a direction of the joint, never by circular movements.
It is forbidden to use scouring agents, materials including steel wool that can scratch the
surface and agents containing aggressive acids. Do not use a stream of water but only a
damp cloth wipe while washing.
After washing, before connecting to the electric system, leave the device to dry completely.

When planning the location of the device there should be taken into account the space for free opening of the
doors, drawers and blinds to remove freely the refrigeration unit for servicing and for free achievement of free
access to clean the condenser.
The devices should be moved away from the wall to ensure free air circulation through the condenser.
Check if the floor is levelled where the device is to be located. Then, level the device, using adjusting
feet, checking whether the door is closed well at the same time.
In accordance with the EN378 standard it should be ensured that the room where the
device with 290 medium is to be located has the proper volume. 1 m3 is required for 8
g of 290 refrigerant. The amount of 290 refrigerating medium is specified on the
rating place of the device.
CONNECTION TO ELECT IC SYSTEM
The construction of the device is made according to the appropriate directives and harmonised
standards:
- low voltage directive 2014/35/UE,
- electromagnetic compatibility directive 2014/30/UE,
- PN-EN 60335-2-8 :2012, PN-EN 60335-1:2012 standards,
- PN-EN 55014-1:2017-06, PN-EN-55014-2:2015-06 standards,
- PN-EN 61000-3-2:201 -04, PN-EN 61000-3-3:2013-10 standards.
The device is adapted to be supplied from the 230V 50Hz line and should be supplied from a separate
low voltage circuit. A grounded plug-in socket must be equipped with anti-shock protection selected,
according to the requirements of local standards and regulations, in compliance with the parameters
specified on the rating plate. The parameters of a residual current device should be selected according to
the current value, specified on the rating plate. The devices are provided with a flexible power supply cable
of HO5VV-F type (3x1,5mm², including protective conductor). The damaged power supply cable should be
replaced by a specialist from technical service or by a skilled person with appropriate qualifications.
The devices are equipped with a terminal to connect external equipotential bonding, marked by a
symbol . Before connecting the device the installation correctness and effectiveness of equipotential
bonding operation should be checked in accordance with PN-IEC-60364-4-41.
The device can be started when effectiveness of anti-shock protection is confirmed by
results of measurements carried out according to the regulations in force.
The device can be connected to the electric system when it is stated that the electric system fulfils the
afore-mentioned requirements. The device is connected by inserting a plug of connecting cable into the
plug-in socket. A device, prepared in such a way, is ready to operate.
Because during transport the device could be inclined by more than 30  from the vertical,
wait about 3  4 hours before connecting the device to the power supply system. Otherwise,
the condensing unit can be damaged.
OPE ATION
The temperature of chilled space and operating cycle of the refrigeration unit can vary. It depends on
the ambient temperature, amounts of inserted fresh products and heat inflow from outside. Therefore it is
necessary to avoid opening the door when unnecessary and inserting warm foodstuffs with temperatures
that significantly exceed the storage temperatures. Otherwise, it can considerably increase the chilling time
of products.
It is recommended to avoid a long contact of the skin with cold surfaces of the device or cold products.
The protective clothing should be used in case of longer contact. The failure to use the protective clothing
can cause torpidity or frostbite.
During operation of the device, observe the rule that the maximum load does not exceed the values
specified in the table and the red symbol in the device chamber. The products should be arranged in such a
manner to allow free air circulation in the undercounter refrigerator or freezer.
The first filling of the refrigerated space should be done after cooling it earlier to the
operating temperature (the required time for the first cooling of the unloaded undercounter
refrigerator or freezer to the set-up temperature: ~ 2h). This rule should be observed also
after a longer break in operation.

It is not recommended to load the table with non-refrigerated products (with a temperature
exceeding ambient temperature or containers with loose fluids as this could cause instant
icing of the system and increased consumption of electric energy and failure to reach the
lowest declared storage temperatures).
From time to time it is recommended to stop the operation of the device to clean its interior, defrost
naturally the evaporator unit, clean the condenser of the refrigeration unit and check the condition of the
door seal. A face heated by electric heater protects the seal against freezing in the freezing devices.
Any replacement of the seal consists in removing the old seal and pushing the new one in the groove of
the profile.
Before performing the afore-mentioned steps, it is necessary to switch off the device by means of a
main switch and remove the plug of connecting cable from the plug-in socket.
Condenser of refrigeration unit must be cleaned at least once every 4 weeks. To clean the condenser,
remove front shutter of the refrigeration unit chamber by removing (depending on model) two or four screws
by hand. For this use a soft brush or a vacuum cleaner.
It is not applicable to products connected to external refrigeration unit (no condensers are fitted).
Do not use a stream of water while cleaning the device. The producer does not assume
responsibility for the damages of the condensing unit arisen as a result of not maintaining
the condenser in a clean state!
The icing of the evaporator is removed automatically. The most frequent reason for the excessive icing
of the evaporator is the failure to observe the procedure of the pre-cooling of a product before placing it in
the freezing device.
All setups of the controller necessary for a normal function of the device are introduced by the
producer.
It is strictly forbidden to intervene in the system parameters of the controller because it may
cause very serious consequences, including damage of the goods and refrigerated
device. In case of the breakdown the goods stored in the device should be protected
against damage. Dora Metal does not assume responsibility for the goods damaged
as a result of the breakdown of the device.
Devices (DM- 40xx, DM-S- 40xx cooling tables; DM- 5044, DM-S- 5044 freezing tables; DM- 404x
and DM- 4060 salad counters) are equipped with automatic condensate drainage system. In other cooling
and freezing tables, the condensate is drained to a tray pulled from underneath the refrigeration unit. Make
sure to monitor level in the condensate container.
Do not move hard, rough objects (e.g. plates) on the sheet metal surface (top, chamber bottom)
that can scratch the surface. Such scratches are not covered by the guarantee.

T ANSPO T
The producer delivers the device protected with cardboard angles and foil. During the transport the
device should be protected against moving.
The device should be transported in an operation position. Upon receipt of the device (before
unpacking) it is necessary to check if any damages did not arise during the transport. All noticed damages
should be immediately notified to the forwarder. In no case, a damaged device can be returned to its
producer, without notification, and without a written permit, received earlier from the producer.
The producer does not assume responsibility for the device that is damaged during the
transport.
DISPOSAL
Prior to the transport the device is protected by a packing crate which consists of the following
recyclable elements: wooden planks, cardboards, propylene fastening tapes, polyethylene foil.
The elements of the device packaging should be kept out of reach of children.
After withdrawal of the device from service it cannot be mixed with other household waste. Before
handing over the device to disposal it is necessary:
- to protect the device by disconnecting the power supply cable,
