UNIT START UP
The Temperature of the cooled space and aggregate operating cycle may fluctuate. This depends on numerous factors, such as the amount and temperature of products placed in the device and temperature of the surroundings. The equipment should be placed in a dry and well-ventilated area, ensuring proper air exchange distance between the wall and the equipment- min. 10cm), out of sunlight, kept far from heat sources and devices enforcing air flow (ceiling and portable ventilators, blow-in heaters). The equipment functions properly in a room, where temperature falls within appropriate climatic class. The operation of the equipment may worsen when operates outside the stated temperature range.
Remarks and indications
- The display case has to be properly levelled, which will prevent noisy corking of the equipment and shall ensure proper water (condensate) outflow during defrosting.
- After transporting the equipment, wait about 2 hours before starting up the unit.
- To ensure proper conditions for the stored products, do not load the shelves completely. Ensure even load of shelves and not to exceed the maximum load.
- The first filling of shelves should be performed after the unit had reached the desired cooling temperature. This principle should also be observed after a long pause in the operation.
- Do not block any ventilation holes, which would hamper the circulation of the cooled air. It is also necessary to ensure proper airflow around the equipment.
- Keep the condenser clean. Impurities may lead to overheating of the compressor and may result in damage, which is not covered by the warranty.
- Do not use electric devices inside the product storing chamber.
- Avoid unnecessary opening of the doors and leaving them open for a longer period of time.
Temperature regulation
The thermostat is to obtain the set temperature within the equipment and maintain it within the determined temperature ranges. The manufacturer enters all settings of temperature regulators required for normal functioning of the equipment. Before primary actuation the user should control and possibly set the required temperature inside the equipment on the control panel.
Digital display – displays the current temperature inside the equipment.
It is forbidden to interfere with systemic parameters of the thermostat, as this can lead to serious consequences, including damages to the cooling unit!

When using the display case, as well as during maintenance works, pay attention not to damage the temperature sensor in the evaporator screen! Do not use mechanical agents to quicken the defrosting process! It is recommended to make a break in the operation once a month in order to clean the interior, naturally defrost the evaporator and clean the condenser.
Figure 8 Cleaning the condenser
It is essential to keep the condenser of the device clean. Dirt may hinder the heat exchange, causing mainly an increase in electric energy consumption and may cause damages to the compressor. In order to clean the condenser it is necessary to unscrew the sheet metal screws and pull the wind brace out of catch by lifting it up. Clean condenser lamellas with help of soft brush or paint brush. If the condenser is extremely dirty (blocking of lamellas) it is indicated to use vacuum cleaner or compressed nitrogen to suck / blow the dirt from between lamellas.
The seller shall not be held responsible for damages of the condenser unit resulting from non-observance of condenser cleaning instructions. Elements of equipment can corrode as result of improper use and maintenance. To prevent damage: Do not allow contact of the with substances containing chlorine and/ or baking soda in different varieties, which destroy the protective layer and components of the equipment (also includes various stainless steel cleaners)
