SAFETY
Dear Customer,
Thank you for choosing our product. Enclosed in this manual, you will find essential information on
the product's functionality, user guidelines, fault diagnosis, and troubleshooting procedures. For
optimal use and understanding of the product, we recommend that you familiarize yourself with
this manual thoroughly.
Important Safety Instructions:
• Operate the appliance within a voltage range of 97V~130V to avoid electrical damage. Utilize
a voltage stabilizer for the compressor if the supply is below 97V or above 130V, especially
for appliances over 500W, to safeguard the cooler.
• The appliance must be connected to a dedicated single-phase socket with a reliable earth
connection. Do not ground the appliance to water pipes or gas lines.
• Avoid storage of combustible, acidic, or corrosive substances in the cooler; these materials
can cause deterioration and pollution.
• Handle the cooler and its electrical components with care to prevent damage and corrosion.
• If the cooler is not in use for an extended period, disconnect it from power and perform
cleaning maintenance before reuse.
• Should the power cord become damaged, replace it with a specific type from the
manufacturer or an authorized service representative.
• Disconnect the appliance from power before cleaning or when exchanging parts.
• Ensure that the sound pressure level of emitted noise is below 60dB(A).
• Do not store items with flammable propellants inside the appliance.
• Dispose of the appliance in accordance with local environmental regulations. Remove doors
to ensure children cannot become trapped.
Caution:
• Be vigilant of fire risks when storing flammable materials; avoid ignition sources.
• Maintain clear ventilation openings in and around the appliance to prevent overheating.
• Refrain from using unapproved mechanical devices for defrosting.
• Avoid damaging the refrigerant circuit.
• Only use manufacturer-approved electrical devices inside the cooler compartments.
• Operate the cooler within the recommended ambient temperature and humidity levels
specified in the product specifications.

NOTE: the water vapor mass in dry air is one of the main points influencing the performance and
the energy consumption of the coolers. Therefore, the order of the climate class in the table is
based on the water vapor mass column.
1. Remove packaging and cleanse the cabinet using warm water mixed with 5% neutral soap.
For cleaning glass parts, opt for specific cleaning products, and avoid using water that
contains lime to prevent residue.
2. Protect the unit from limescale deposits by leaving a gap of at least 10 cm from the wall.
Settle the appliance by adjusting the feet for level stability.
3. Position the cabinet on a completely flat surface, well-distanced from any heat sources,
including direct sunlight.
4. Ensure the appliance is placed indoors and sheltered from rain exposure.
Site Selection
The appliance is intended exclusively for indoor use. Given the glass door, environmental factors
significantly influence its performance. To optimize efficiency, adhere to these recommenda-
tions:
• Avoid proximity to heat sources.
• Do not place near or in the path of air currents from ventilation systems or open windows
and doors.
• Refrain from situating the appliance beneath roof-mounted ventilation.
• Ensure there is ample 'breathing' space around the unit, particularly at the back for adequate
air circulation.
• Do not expose the appliance to direct sunlight.
Ventilation and Safety:
• Maintain clear ventilation for the appliance to prevent obstruction. Install the appliance
away from any structures that could impede airflow.
• Installation should be performed exclusively by certified professionals to mitigate fire risks.
Leveling the Appliance:
• For optimal performance, ensure the appliance is level. Use a spirit level to check both
directions.
• It's advisable to place the spirit level on one of the appliance's shelves for accuracy.
• Proper leveling is crucial to prevent ice build-up due to poor drainage of condensation.
• Adjust the feet as needed to facilitate door opening and condensate drainage.
Cautionary Notes:
• Do not store cream or spray containers, particularly those with flammable propellants,
inside the appliance.
• Flammable materials in aerosol cans should never be stored in the appliance due to explo-
sion risk.
Product Highlights:
• The appliance operates efficiently within a broad voltage range and performs optimally even
above room temperature, due to a well-matched cooling system.
• The contents are visible through the elegant, hollow glass door.
• Insulation is provided by a high-quality polyurethane foam, ensuring the interior remains
chilled and conserves energy.
