This document serves as a user manual for the LCC CARINA 01 and LCC CARINA 02 pastry counters manufactured by ES SYSTEM K SP. Z O.O.

Function Description:

The refrigerated cabinet LCC Carina is designed for the display and direct sale of pastries and fruits/vegetable salads, maintaining a temperature range of +3 to +8 °C. A specialized version is available for chocolates, equipped with a hygrostat to ensure a correct level of humidity and protect against humidity spikes. This version operates within a higher temperature range, specifically +14 to +18°C, which is ideal for chocolates. It's important to note that the hygrostat helps lower humidity inside the cabinet; it does not increase it. The cabinet is not intended for refrigerating products but rather for displaying them for sale purposes. Products placed inside should already be at or below the set temperature of the cabinet.

The cabinet operates using a refrigerated system that includes a condensing unit, an evaporator dosage element (capillary tube/valve), and an electric heater for the evaporator. Some versions can be prepared without an internal condensing unit for remote connections to a cooling installation. Cooling is achieved by an evaporator through which air is blown by fans. Cooled air is distributed through an air outlet in the bottom shelf to all levels of the exposition area, then sucked back through an air inlet on the bottom shelf and directed to the evaporator, repeating the cycle. The cabinet is equipped with an electric controller on the control panel to manage various parameters, including temperature, defrosts, and alarms.

Important Technical Specifications:

The cabinet is a self-supporting construction built on a metal frame with adjustable feet for proper leveling. Internal elements are made from powder-painted metal, inox, and a waterproof MDF worktop. External surfaces are also made from MDF and powder-painted metal. Polyurethane foam provides insulation. The display area features a waterproof MDF bottom and glass shelves, each illuminated by warm T8 light tubes. The cabinet boasts panoramic bent front glass (double-glazed), double-glazed side glasses, and double-glazed doors in a metal frame at the back, ensuring excellent insulation and minimal heat loss. The front glass can be opened for easier cleaning access. An anti-mist heater is located at the bottom edge of the front glass to prevent condensation when environmental humidity rises.

The cabinet is designed to operate within specific environmental conditions: relative humidity of 60%RH, temperature of +25°C, and air flow less than 0.2 m/s. These conditions may vary for the tropic version of the cabinet. The maximum loading limit for glass shelves is 25 kg/m². The cabinet is prepared to be powered by 230 V, 50 Hz, via a cable with a plug.

Usage Features:

Before initial use, it is crucial to read the entire user manual. The cabinet must be installed and launched in accordance with manufacturer's directions and local laws. In case of malfunction, the cabinet should be turned off, and service should be contacted.

Installation:

Place the cabinet in its designated location.
Level the cabinet using the adjustable feet.
Ensure that air exchange to the condenser is not restricted.
Leave at least 80 cm of free space in front of and behind the cabinet.
The floor must be flat and leveled.
Nothing should block air exchange in the bottom part of the cabinet.
The cabinet should not be placed near heat sources (heaters, ovens, light sources).
Air from air conditioning systems or ventilation should not be directed towards the cabinet.
The cabinet should not be placed in direct sunlight.
No other cabinet should be connected to the same fuse, and the cabinet should not cover the socket it's connected to.
The plug must be connected only to sockets with a grounding bolt, or the socket must be secured with a proper fuse.

Turning ON:

Connect the plug to the electric socket.
Put all switches on the control panel to the "I" position. The condensing unit, fans, light, and anti-mist heaters will start.
If installed, the hygrostat should be turned on to dry the air inside the display area and maintain humidity.
Wait 90 minutes for the cabinet to reach its set temperature before loading products.

Loading with Products:

Place products gently on the exposition area.
Do not exceed the loading limit of 25 kg/m² for glass shelves.
Do not let products stick out from glass shelves to avoid disturbing airflow.
Maintain at least 10 mm distances between products on exposition shelves, ensuring products do not cover air inlet or outlet.
Do not cover the perforation on metal frame covers around the condensing unit.
Keep back doors closed at all times when no sale takes place to ensure correct product temperature and reduce operating costs.

Controller Display:

In standard mode, the display shows the current internal temperature and information about the working condensing unit. It also displays defrost alerts, alerts for probe malfunctions, and alerts for cabinet malfunctions. Temperature settings can be adjusted within the manufacturer's specified ranges, as described in the controller manual.

Automatic Defrost:

The controller manages automatic defrosting. Defrost water is directed through a drain in the bottom of the mold and a pipe to a container in the bottom of the frame or directly to canalization drains. It's essential to regularly check that the drain is clear and water flows smoothly. In high humidity environments, additional defrost cycles may be necessary; refer to the controller manual for details.

Power Shortage:

After a power shortage or unplugging/plugging, the cabinet will turn on automatically. Check if the water container has overflowed and if the cabinet is working properly after power is restored.

Maintenance Features:

Cleaning Before First Use:

Clean all exposition surfaces (shelves) with a gentle detergent.
Use detergents specifically for inox elements on inox surfaces.
Ensure detergents are not active or aggressive towards the cabinet materials.
Dry all surfaces and empty the removable drain container at the bottom.

Cleaning During Usage:

It is absolutely necessary to defrost and clean the cabinet fully once a week. This ensures optimal performance for the following week. During defrost, the internal temperature will rise slightly but will not affect products due to the short duration.

At least twice a year, perform the following:

Turn off all switches on the control panel (position "0").
Unplug the cabinet from the socket.
Remove all products from the display area.
Wait until the cabinet reaches ambient temperature.
Clean the interior of any remains and leftovers.
Control water drains and remove any dirt.
Wash all exposition surfaces with a gentle, non-toxic, non-active detergent. For inox surfaces, use a special detergent. Dry surfaces with a soft towel.
Wash internal surfaces of the front glass by opening it carefully. Support the glass with your free hand while washing.
After cleaning, turn the cabinet back on as described in the "Turning ON" section.

Regularly check:

Noise level is normal.
Inlet and outlet of air are not blocked or covered.
Evaporator is clean.

Cleaning of Condenser:

A dirty condenser is a common cause of malfunctions.

Check if the condenser is clean at least once a month, or more frequently if necessary.
If cleaning is needed:
1. Turn off the cabinet by putting the main switch in "0" position and unplugging it.
2. Remove the rear metal cover to access the condenser.
3. Clean the condenser with a soft brush or low-power vacuum cleaner.
4. Check for airflow through the condenser and ensure dirt is not blocking spaces between plates.

Regularly check:

Noise level is normal.
Condenser is clean.
Air flow through the condenser is sufficient. If a dirty condenser caused the malfunction, check if the cabinet functions properly after cleaning. If not, contact service.

Detecting and Removing Malfunctions:

If the cabinet or any component malfunctions, or if it doesn't work properly, first check if it poses a danger to people or property. If necessary, contact service.

Before calling service, check:

The plug is connected, and electric supply is ensured.
The cabinet's fuse is not burned.
The cabinet is leveled properly.
The condenser is not covered or blocked.
Products are correctly placed inside the cabinet.
Airflow in the cabinet is not disturbed.
The defrosting cycle is not in progress (temperature display blocked during defrost and shortly after). Wait 1-1.5 hours, then check the temperature. If it's still too high, it may indicate a malfunction. If the cause of malfunction cannot be found, turn off the cabinet from electricity and call service.

Service and Spare Parts:

Cabinet characteristics are on the label plate. When contacting service, always provide the serial number and cabinet type. For more technical data, contact service or your distributor. Only qualified staff should perform service duties on electric and mechanical parts. The evaporator should only be cleaned by authorized service. It is strongly suggested to use manufacturer's spare parts.
