PURPOSE
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.
Note: 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
REFRIGERATED SYSTEM OPERATION
There is one-step, compressor’s refrigerating cycle in the device. The refrigerated system is filled with an
ecological refrigerating medium R290 – data specified on the rating plate.
Appliances in DM-926_ _ - BA series are designed for remote cooling circuits and don’t have compressor.
INTERIOR TEMPERATURE SET-UP
An electronic temperature controller sensor is located in the rear part of the chamber ceiling. The controller
is programmed in such a manner that the device achieves an interior temperature specified in the technical
data. For the method of the required temperature set-up – see page 16.
START-UP PREPARATION. 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 cleaning agent
dedicated for stainless steel – after this operation the surface should be washed out and dried.
In daily cleaning also use generally available cleaning agents dedicated for stainless steel
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. The devices should be moved away from the wall to ensure free air circulation through the
condenser. It is necessary to leave 40 cm of free space at least above the device and not less than 10 cm of
free space on the sides and at the back which ensures a proper air circulation for the correct operation of the
device.
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 R290 medium is to be located has the proper volume. 1 m3 is required for 8 g of R290
refrigerant. The amount of R290 refrigerating medium is specified on the rating place of the
device.
CONNECTION TO ELECTRIC SYSTEM
The construction of the device is made according to the appropriate directives and harmonised standards:
- low voltage directive 2006/95/EC,
- electromagnetic compatibility directive 2004/108/EC,
- PN-EN 60335-2-89:2012, PN-EN 60335-1:2012 standards,
- PN-EN 55014-1:2012, PN-EN-55014-2:1999 standards,
- PN-EN 61000-3-2:2007, PN-EN 61000-3-3:2009 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 1 hour before connecting the device to the power supply system. Otherwise, the
condensing unit can be damaged.

OPERATION
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 upright 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 upright refrigerator or
freezer to the set-up temperature: ~ 2h). This rule should be observed also after a longer break
in operation.
It’s not recommended to place in chamber not chilled products (which have temperature higher
than ambient or opened containers with liquids). Such situation can cause fast icing of cooling
circuit, higher energy consumption and worse performance (problem with achieving lowest
declared 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.
The condenser of the refrigeration unit should be cleaned not rarely than every 4 weeks. It should be
cleaned by means of a soft brush or vacuum cleaner
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.
The devices are provided with an automatic condensate evaporation system. The condensate in the
engine room is evaporated by means of electric heater
