• Refrigerant: This appliance uses R600a refrigerant. Handle with care and ensure proper ventilation if a leak is suspected. Do not damage the refrigerant circuit.
• Cleaning: Always unplug the freezer before cleaning. Use a soft cloth and mild detergent. Avoid abrasive cleaners.
• Children: Keep children away from the appliance. Do not allow them to play with or inside the freezer.
• Disposal: Dispose of the appliance according to local regulations for refrigerants and flammable insulation gases.

3. Setup

3.1 Unpacking

1. Carefully remove all packaging materials, including foam and adhesive tape.
2. Inspect the freezer for any damage during transit. If damaged, do not operate and contact your supplier.
3. Clean the interior and exterior of the freezer with a damp cloth before first use.

3.2 Placement

• Place the freezer on a stable, level surface to ensure proper operation and prevent vibrations.
• Allow sufficient space around the freezer for adequate air circulation (at least 10 cm on sides and back, 30 cm above).
• Avoid placing the freezer near heat sources (e.g., ovens, radiators) or in direct sunlight.
• The door hinge is on the right side and can be reversed if needed by a qualified technician.

3.3 Power Connection

• After placement, wait at least 2-4 hours before plugging the freezer into the power outlet. This allows the refrigerant to settle.
• Plug the power cord into a dedicated, grounded 230 V / 1N/PE / 50 Hz electrical outlet.

4. Operating Instructions

4.1 Initial Operation

1. Once plugged in, the freezer will begin to cool. Allow it to operate for several hours (e.g., 4-6 hours) empty to reach its stable operating temperature before loading food.
2. The temperature range for this mini-freezer is between -13 °C and -22 °C. Adjust the thermostat control (if present) to your desired setting.

4.2 Loading the Freezer

• Do not overload the freezer. Leave space between items for proper air circulation.
• Ensure all food items are properly sealed to prevent freezer burn and odor transfer.
• The freezer has a net volume of 32 liters and features one cooling compartment with one door.

4.3 Door Operation

• The freezer is equipped with a soft-close/open door system for smooth operation.
• Ensure the door is fully closed after each use to maintain the internal temperature and energy efficiency.

5. Maintenance and Cleaning

5.1 Defrosting

• Over time, frost will accumulate inside the freezer. Defrost the appliance when the frost layer becomes about 5mm thick.
• To defrost, unplug the freezer and remove all frozen items. Place them in another freezer or cooler.
• Leave the freezer door open to allow the frost to melt naturally. Place a towel or shallow pan to collect water.
• Do not use sharp objects or heating devices to speed up defrosting, as this can damage the cooling system.
• Once defrosted, clean and dry the interior thoroughly before plugging it back in and reloading.

5.2 Cleaning

• Always unplug the freezer before cleaning.
• Clean the interior with a solution of mild detergent and warm water. The rounded inner corners facilitate easy cleaning.
• Wipe the exterior with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners.
• Regularly clean the condenser coils at the back of the freezer (if accessible) with a soft brush or vacuum cleaner to maintain efficiency.
• Ensure all parts are dry before plugging the freezer back in.

6. Troubleshooting

Before contacting customer service, review the following common issues and solutions:

• Freezer does not operate:
  • Check if the power cord is securely plugged into a live outlet.
