1.3 Initial Cleaning
Before first use, clean the interior and all accessories with lukewarm water and a mild detergent. Rinse thoroughly and dry completely.
1.4 Electrical Connection
Connect the appliance to a properly installed earthed socket. Ensure the voltage and frequency match the specifications on the rating plate. Do not use extension cords or multiple sockets.
1.5 Initial Startup
After connecting to power, allow the appliance to run empty for approximately 2-3 hours to reach the desired operating temperature before loading bottles.
2. Operating Instructions
Understanding the controls and features will help you maintain optimal conditions for your beverages.
2.1 Temperature Control
The bottle cooler is equipped with an adjustable thermostat. To set the desired temperature, rotate the thermostat dial located inside the appliance. Turning the dial towards higher numbers typically results in colder temperatures. Allow several hours for the temperature to stabilize after adjustment.
2.2 Loading Bottles
- Distribute bottles evenly on the shelves to ensure proper air circulation and prevent overloading any single shelf.
- Avoid blocking the internal fan or air vents, as this can impair cooling performance.
- Do not place hot items directly into the cooler; allow them to cool to room temperature first.
2.3 Internal Lighting
If your model includes internal lighting, it is typically controlled by a switch located near the light fixture or on the control panel. Use the lighting to illuminate the contents as needed.
3. Maintenance and Care
Regular maintenance ensures hygienic operation and extends the lifespan of your appliance.
3.1 Cleaning the Interior
- Disconnect the appliance from the power supply before cleaning.
- Clean the interior regularly with lukewarm water and a mild, pH-neutral detergent. Avoid abrasive cleaners or solvents.
- Pay special attention to door seals; clean them with clear water and dry thoroughly to maintain their elasticity and sealing properties.
- Dry all surfaces completely before reconnecting power.
3.2 Cleaning the Exterior
Wipe the exterior surfaces with a soft, damp cloth. For stainless steel surfaces, use a specialized stainless steel cleaner if necessary, following the product instructions.
3.3 Defrosting
This appliance features automatic defrosting. The evaporator thaws automatically, and the resulting condensation water evaporates. Ensure the drain opening at the back of the interior is not blocked to allow water to flow freely.
4. Troubleshooting
Before contacting customer service, please check the following common issues and solutions:
- Appliance does not cool:

- Temperature is not cold enough:
- The door may not be closed properly.
- Too much warm air may be entering due to frequent door openings.
- The ventilation openings might be blocked.

- Ensure the appliance is level and stable.
- Check if any objects inside are vibrating against each other.
- Normal operating noises include gurgling (refrigerant flow) and clicking (thermostat).
