Frequently Asked Questions - LKR3455BER Concept

How do I adjust the temperature in my Concept LKR3455BER refrigerator?

To adjust the temperature, locate the thermostat dial inside the fridge compartment (usually near the top right or back). Turn it clockwise for colder, counterclockwise for warmer. The recommended setting is medium (3-4).

Why is my refrigerator not cooling properly?

Check if the power cord is plugged in and the thermostat is set correctly. Ensure the door seals are clean and tight, and that air vents are not blocked by food items. Also, allow 24 hours after first installation for temperature stabilization.

How often should I defrost the freezer?

Your model features No Frost technology, which automatically prevents ice buildup. No manual defrosting is required. However, if you notice frost, check the door seal or call service.

What is the best way to clean the interior?

Unplug the appliance. Remove all food and shelves. Clean with a soft cloth using warm water and mild dish soap. Avoid abrasive cleaners or scouring pads. Dry thoroughly before restoring power.

Can I reverse the door opening direction?

Yes, the doors are reversible. Refer to the manual for step-by-step instructions. You will need a screwdriver and possibly a friend to hold the door. It involves swapping hinges and door handles.

What does the 'ECO' mode do?

ECO mode optimizes energy consumption by slightly raising the temperature during low use periods. It reduces electricity bills without affecting food preservation significantly. Activate it via the control panel.

Why is there water pooling inside the fridge?

Water usually comes from a blocked defrost drain. Clean the drain hole (located at the back of the fridge interior) with a pipe cleaner or cotton swab. Also ensure the drain tray isn't cracked.

What should I do if the door alarm sounds continuously?

The alarm indicates the door has been left open for more than 60 seconds. Close the door firmly. If it persists, check if something is blocking the door or if the magnetic seal is damaged.

How can I replace a broken shelf?

Contact Concept customer support or an authorized parts dealer. Provide your model number (LKR3455BER). Always order genuine tempered glass shelves to ensure safety and fit.

How do I reset the control panel after a power outage?

The device should restart automatically. If the panel is unresponsive, unplug for 5 minutes, then plug back in. If issue persists, press and hold the Power button for 10 seconds to force reboot.

TIPS FOR USE

- If there is a power failure or the cord has been pulled out of the wall socket, it is necessary to wait at least 5 minutes before reconnecting the appliance. This 5-minute delay is done to prevent compressor damage.

- During a power failure, food can be stored for several hours inside the refrigerator and freezer. Open the door of the refrigerator and the freezer as little as possible in order to extend the freshness of the stored food.

- If you do not use the appliance for a long time, disconnect the appliance from the mains, clean the inside of the appliance with non-aggressive detergents (see the Cleaning and Maintenance section) and leave the appliance door open to prevent unpleasant odours inside the appliance.

- The ambient temperature in the room, the temperature of the food, the amount of food stored, and how often the door of the appliance gets opened have an effect on the temperature inside the appliance.

- If you do not attend to store frozen food, there is no need to have the freezer set to the maximum cooling power. If you leave the temperature set to the maximum cooling power for a long time, the drain line may get frozen.

Tips for storing food in a refrigerator

The refrigerator is used to store fresh food for several days.

• Be aware that stored food should not touch the back wall. Leave some space around the individual items to ensure air circulation in the refrigerator.
• Do not put hot food or drinks in the refrigerator. It will increase the humidity inside the refrigerator.
  • Store the food in closed containers or packed.
  • Store liquids in closed containers or bottles.
  • It is recommended to place the wrapped meat on the glass shelf above the fruit and vegetable drawer.

Please follow the instructions below to avoid degrading of stored food.

• Do not open the refrigerator door for longer than necessary, as the supply of warm air significantly increases the temperature inside the appliance.
• Clean surfaces that may be in contact with food and drainage channels regularly.
• Fresh meat and fish should be stored in a suitable place to avoid contact with other foods.

Tips for storing food in a freezer

The freezer is used to freeze fresh food, store frozen food for the time specified on the packaging and to produce ice.

• Pack the fresh food airtight. Special freezer bags, polyethylene bags and plastic containers are ideal.
- Prevent fresh food from coming into contact with already frozen food.
- In case of power failure, open the freezer door only when necessary and as little as possible. The freezer keeps the food frozen for up to 12 hours.
- Never place warm food or beverages in the freezer.
• Before putting frozen food into the freezer, make sure the packaging is not damaged.
- It is also not recommended to put beverages in glass bottles in the freezer, glass can easily rupture due to low temperatures inside the freezer.

USER MANUAL

Before first use

Before first use you should wipe the outside and inside of the appliance with a damp cloth for hygiene reasons. Wash all removable parts with warm soapy water.

After installing the refrigerator, leave the appliance standstill for at least 2 hours before connecting to the mains. It is necessary to allow the cooling gases to set down. Then you can connect the refrigerator to the mains and let it run for 2-3 hours to stabilize a normal operating temperature. Then put fresh or frozen food inside the appliance.

Note: If a power failure occurs during the first run, wait for at least 5 minutes before switching on again or connecting to the mains.

Setting the Temperature of Refrigerator Zone

1. Open the refrigerator door.
2. You can set the internal temperature of the refrigerator compartment and freezer compartment with the inside temperature controller (figure 1).
3. Turn the knob from position 1 to position 5 to get a cooler temperature inside the appliance.

- The numbers displayed on the controller do not indicate a specific set temperature, but a temperature level

- If the thermostat is set to position 0, it is switched off and the appliance does not cool or freeze.

- For normal food storage in the freezer, set the thermostat to position 2 to 4.

- The refrigerator should be in operation for at least 24 hours to reach the required cooling temperature.

Allow the refrigerator to cool completely before placing food. It is best to wait 24 hours before placing food in the refrigerator.

Defrosting

1. Disconnect the electrical plug from the mains
2. Move food from the refrigerator to place where it will not be spoiled, prepare a container to catch defrosting frost
3. Wipe the thawed water on the evaporator and the inner lining with a dry cloth, then wring the cloth out and repeat the process until the ice has completely thawed
4. To speed up the defrosting process, you can use an ice scoop (use only a plastic or wooden scoop to avoid damaging the seal and the inner lining) or a very fine brush in combination with the use of an adequate amount of warm water.
5. After complete defrosting and wiping the residual water inside the refrigerator with a dry cloth, you can put the food back in the refrigerator and switch on the appliance.

It can be caused by expanding and shrinking of the air inside the refrigerator and freezer.

Short cracking

It can be heard when the thermostat turns on and off the compressor.

Noise of the compressor

Running compressor produces noise. After the installation of the appliance, the compressor may be a little louder for a short time.

Bubbling and flowing

This sound is generated when the refrigerant is flowing through the appliance pipes.
