Upright refrigerators and freezers
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.
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.
