3.2 Door Reversal (if needed)
The Electrolux KNS5LE18S features reversible doors, allowing you to change the door hinging from right to left, or vice-versa, to suit your kitchen layout. Refer to the installation video (Video 1) for a step-by-step guide on how to perform this operation. This typically involves:
- Removing the top and bottom hinges.
- Transferring hinge pins and covers to the opposite side.
- Reattaching the doors and adjusting for proper alignment.
3.3 Positioning and Securing
Position the refrigerator into the designated cabinet opening. Ensure it is level using the adjustable feet. Secure the appliance to the cabinet using the provided brackets and screws. The installation video (Video 1) demonstrates the precise steps for securing the unit and attaching the cabinet doors to the appliance doors via the sliding hinge system.
3.4 Electrical Connection
Connect the appliance to a properly grounded electrical outlet. Ensure the voltage and frequency match the specifications (220-240V, 50Hz). Avoid using extension cords or multiple socket adapters. Allow the refrigerator to stand upright for at least 4 hours before plugging it in to allow the refrigerant to settle.
4. Operating Instructions
Your Electrolux KNS5LE18S refrigerator is designed for intuitive operation. Familiarize yourself with the control panel and its functions.
4.1 Control Panel
The control panel is located at the top of the refrigerator compartment. It typically includes buttons for temperature adjustment, mode selection, and an indicator for the current temperature.
4.2 Temperature Setting
To adjust the temperature, press the temperature control buttons (usually marked with '+' and '-'). The recommended temperature for the refrigerator compartment is typically +5°C, and for the freezer compartment, -18°C.
4.3 ColdSense Technology
The ColdSense technology rapidly restores the internal temperature after the door has been opened, minimizing temperature fluctuations. This helps to preserve food quality and reduce waste.

4.4 LowFrost System
The LowFrost system reduces ice build-up in the freezer compartment, making defrosting easier and less frequent compared to conventional static freezers. When defrosting is necessary, it will be a quicker process.
5. Maintenance
Regular maintenance ensures the efficient operation and longevity of your refrigerator.
5.1 Cleaning
- Always unplug the appliance before cleaning.
- Clean the interior and exterior surfaces with a soft cloth and a mild, non-abrasive detergent.
- Wipe down door seals regularly to ensure a tight seal.
- Clean the condenser coils at the back of the appliance periodically (at least once a year) to maintain energy efficiency.
5.2 Defrosting
Thanks to the LowFrost system, manual defrosting of the freezer is required less often. When a layer of ice approximately 5mm thick has formed, it's time to defrost. To defrost:
- Turn off the appliance and unplug it from the power supply.
- Remove all food items and store them in a cool place.
- Leave the freezer door open to allow ice to melt naturally. Place towels or a tray to collect melting water.
- Once defrosted, clean and dry the interior thoroughly before restarting the appliance.
6. Troubleshooting
Before contacting customer service, check the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Appliance does not operate. | No power supply; plug not inserted correctly. | Check power supply and plug connection. |
| Temperature is too high. | Door not closed properly; large amount of warm food inserted; temperature setting too high. | Check door seal; avoid placing large quantities of warm food; adjust temperature setting lower. |
| Excessive noise. | Appliance not level; parts touching other objects. | Adjust leveling feet; ensure no contact with walls or furniture. |
