Warning
Attention
Transportation and Placement
• Check Accessories Before Transport: When unpacking, ensure all accessories are present.
After verication, repack securely before transporting.
• Handle with Care: Avoid tilting the unit more than 45° during transport to protect the cooling
system. Do not shake or drop the unit.
• Stable Placement: Place the appliance on a at, solid, and level surface to ensure stability and
proper operation. This is essential for both safety and performance.
• Clearance: Maintain at least 2 inches of clearance around the unit for proper ventilation and
energy eciency.
• Before First Use: Remove any plastic protective covers from the plug before connecting to
power. Do not load food until the appliance has been running for a short period to reach the
correct temperature.
• Leveling and Cushioning: If elevation is needed, use a stable and solid support — never use
soft or unstable materials like foam or plastic sheets.
• Avoid Moisture: Do not place the appliance in damp or polluted areas. Clean any water or dirt
immediately with a soft cloth to prevent insulation damage.
• Temperature Conditions: Do not place the appliance in areas that are extremely cold, outdoors,
or exposed to rain. Avoid direct sunlight and heat sources to maintain proper performance.
Warning: High temperature hazard.

Operation
First-Time Setup
• Place the machine in its proper position and open the door to allow ventilation.
• Even though the unit is cleaned at the factory, it is recommended to clean it again before use.
• Run the machine empty for the initial operation. Set the thermostat and connect the appliance
to the power supply.
• It is normal for the compressor to stop briey after running for a short time while the internal
temperature adjusts.
• Once the inside temperature has cooled to the desired level, the unit will automatically switch
on or off as needed.
• For best results, wait until the inside temperature reaches the proper cooling level before
placing items inside the showcase.
Thermostat
• The cabinet temperature is controlled by the thermostat located on the control panel. The ther-
mostat allows you to select the appropriate cooling level based on ambient temperature, the
type of goods stored, and the quantity inside.
• The thermostat knob is marked with positions 0 to 7 (these numbers indicate refrigeration lev-
els, not exact temperatures):
• Position 1 – Highest temperature setting (least cooling)
• Position 7 – Lowest temperature setting (maximum cooling,
compressor runs continuously)
• Position 0 – Compressor is off (no cooling)
Lighting
• Press 0 Lamp is OFF
• Press – Lamp is ON

Maintenance
Cleaning and Maintaining the Appliance
• Unplug Before Cleaning: Always disconnect the appliance from the power supply before clean-
ing.
• Use Mild Cleaning Materials: Clean with a soft cloth or sponge using clear water or mild soap.
• Avoid Harsh Chemicals: Do not use organic solvents, alkaline cleaners, hot water, or acids on
the showcase.
• Compressor Room Cleaning: Do not use water directly in the compressor room. Instead, use a
slightly damp cloth to remove dust, then wipe with a dry cloth to prevent rust.
• Hot Food Warning: Allow hot food to cool before placing it in the fridge compartment to avoid
reducing cooling eciency or damaging the unit.
• Airow Clearance: When placing food, keep adequate space between items to avoid blocking
airow to the cooling air inlet and outlet.
• Door Use: Minimize how often the door is opened. Keep it closed tightly to maintain eciency
and save energy.
• After Power Loss: If power is cut, wait at least 5 minutes before turning the appliance back on
to protect the compressor and extend its lifespan.
• Temperature Recovery: After a power outage or other failure, wait until the internal tempera-
ture stabilizes before resuming use.
• Long-Term Storage: If not using the appliance for an extended period, turn it off, unplug it,
clean it thoroughly, and keep the door slightly open to prevent odors.
• Frequent Power Cycling: Avoid repeatedly turning the power on and off within short intervals,
as this can shorten the appliance’s lifespan.
Auto-Defrost
• When the compressor stops, the appliance’s internal temperature will rise. Frost on the evapo-
rator will thaw and drain into the water box in the compressor compartment through the drain
hose.
• The water in the box will naturally evaporate from the compressor’s heat during operation, so
manual defrosting is not required.
