4. OPERATION
4.1. Operation Requirements
e temperature inside the refrigerated compartment of the cabinet and its operation cycles may vary due to dierent reasons (such as
the temperature of refrigerated foodstu, the ambient temperature in the premises, door opening frequency, etc.).
Upright cabinets are designed for operation only in the particular climate class! The manufacturer is not responsible for
the normal operation of the unit in the climate class, other than specified in the technical characteristics (indicated on the
data plate).
• To ensure proper and long-lasting operation of JUKA Upright Cabinets, please follow the recommendations indicated below:
• Aer transporting the equipment, wait for about 2 hours before its launching
• e counter should be installed away from direct sunlight
• Before stocking the unit with refrigerated products, wait until the desired temperature is reached
• Do not place warm or hot products inside the upright cabinet
• Do not store beverages in bottles and cans, especially carbonated beverages, in the freezer chamber. e cans and the bottles may
explode.
• Do not store explosive substances, such as ammable aerosol cans, inside the unit
• During the day it is not allowed to place more products in the chamber of the unit than its freezing capacity can handle
• To ensure proper storage conditions, please avoid full loading of the grid shelves
• To prevent the packaging from freezing, dry it thoroughly before placing it in the appliance.
• Do not block the ventilation openings inside the freezer as it may prevent your appliance from functioning properly.
• Keep the condenser clean. e buyer should periodically perform technical maintenance to avoid malfunctions and/or unsatisfying
operations of the cabinet.
• Aer closing the doors, do not try to use force to open them. e cooling of the gas causes a reduction in pressure inside the freezer, resulting
in a partial vacuum that makes the door more dicult to open. In 1 – 2 minutes pressure equalizes and the door becomes easier to open.
• Please avoid unnecessary openings of the door, as well as do not leave the door open for a long time.

5.1.3. Condenser Maintenance
e user should periodically check the condition of the condenser. e ingoing and outgoing
air openings of the condenser must not be blocked by objects. A dirty condenser leads to reduced
cooling capacity, overheating of the refrigeration unit and even damage to the compressor.
ATTENTION! e condenser needs to be cleaned at least once a month.
Clean the condenser ns with a so brush or paintbrush. To do that:
1) Disconnect the device from the power source;
2) Remove the protective grill covering the unit;
3) Using a so brush, clean the condenser from dust, remnants of the package, etc. (Pic. 16);
4) Aer cleaning, place the protective grill in reverse order.
In case of dirty condenser (dust between the condenser ns) it is recommended to use an air compressor or compressed nitrogen to
blow out the contaminants between the ns.
e compressor is equipped with an internal backup (thermal) switch, which protects the engine from accidental overloads. If you hear unnatural,
loud operation or the heavy start of the compressor, switch o the appliance, check the condition of the condenser (in case of pollution - clean it).
WARNING! Failure to perform this service can result in a complicated starting of the compressor, the operation of the unit, the
overheating of the compressor and, consequently, deterioration of the cooling eciency.
e manufacturer is not responsible for damage to the unit that arose as a result of noncompliance with the purity of the condenser!

5.1.4. Door Seal
e door seal should be cleaned regularly with clean water without detergents, and then wiped dry with a so cloth. Please make sure
that the cabinet door close properly aer cleaning. To check the state of the door seal place a sheet of paper between the seal and the cabinet
body and close the door. When you try to pull out the paper, you should feel moderate resistance.
5.1.5. Other Terms and Conditions
Metal parts of the equipment can corrode in case of improper use and maintenance. To prevent corrosion of the metal parts, please:
• Do not use any cleaning agents that contain chlorine and sodium of dierent types as they can damage the protective layer and parts of
the unit (including dierent types of stainless steel).
• During cleaning and maintenance of the equipment, please make sure not to damage the data plate of the unit. e data plate contains
useful product-specic data.
6. FAULT IDENTIFICATION AND REPAIR
In case of any problems during the startup of the equipment or its operation, it is necessary to return to those sections of the service

 Equipment does not reach the appropriate temperature, the lighting is on:
Make sure that:
• e main switch is turned on
• e temperature setting on the controller is set correctly
• e controller is operating properly
• e condenser is not lthy, and clean it when necessary
• e ambient temperature does not exceed 35 °
• Enough time has passed for products to be cooled
• e cabinet does not have too many products and does not exceed the maximum freezing capacity
• e door hardware closes correctly and the sealant is adjacent to the hardware case
• Check that the ventilation openings are not blocked
• Check whether the evaporator is not ooded. If necessary, complete preventive defrosting of equipment, pre-shiing the products to
another location with the appropriate mode.
 e equipment is working too loud:
Make sure that:
• e device is standing stably and is properly levelled
• Furniture adjoining the device do not vibrate when the compressor is working
• Internal elements have been properly mounted
 Dirty condenser alarms (cht, CHt):
cht - pre-alarm indicating that condenser is dirt. cht is shown on the display, alternating with the current temperature while cabinet
operates normally. e alarm will be reset when temperature is normalized.
CHt - dirty condenser alarm. Alarm indicates that condenser is dirty and the condenser temperature is high. CHt switch o the compressor
and switch on the alarm (to reset the alarm press «SET»). CHt is shown on the display, alternating with cht and the current temperature.
WARNING! e “CHt” alarm can only be reset manually by switching the unit o (on power-up, if the temperature is still above
the normal, the alarm will go on again).
dor - door alarm. When the door is opened, the controller will start counting the pre-alarm time and block operation of the ventilator.
When time is over, the alarm will be activated immediately and the display will show “dor” alternating with the temperature reading.
Ventilator resumes its operation. e alarm will be reset when the door is closed.
