inside the unit. When uncrating, remove any cardboard from the exterior and the door area carefully
to avoid any damage from sharp tools.
Placement
Position the appliance on a sturdy, level surface to prevent:
Noise from an uneven surface
Potential malfunctions from an uneven surface
Use shims or supports to level the appliance if the floor is irregular.
Ventilation
Install the appliance indoors in a spot with good air circulation to:
Maximize efficiency
Maintain a clearance of at least 4 inches (100mm) at the back and 2 inches (50mm) on top.
Prevent efficiency loss and potential damage from outdoor placement.
Environment
Avoid placing the appliance in areas of high humidity or dust because:
Humidity can lead to rust, affecting performance.
Dust on the condenser coils can lead to malfunctions.
Clean the condenser coil regularly to ensure proper function.
The appliance should not be placed in areas where it could be exposed to rain or direct sunlight.
Do not situate the appliance in locations with chlorinated or acidic conditions, such as near swim-
ming pools or bath areas, as these environments could cause corrosion.

■ Shelving installation
1.Remove both sliding rear doors by lifting each
door up and pullingout at the bottom.
2.Install left andright shelf brackets teeth end
into stainless pilasters,adjust to desired height
matching right.
3.Hang front and rear shelf support panels to the left and right shelf brackets,screw them on
both left and right sides.
4. Plug light to the socket on stainless pilasters 5. Position glass shelves
6. Refit the sliding doors by lifting each door up into the top track and placing onto the bottom track.
Securing the Castors:
Once the cabinet is in place, make sure to lock the castors (wheels)
to prevent it from moving. This unit comes with both castors and
adjustable feet. The adjustable feet are designed to secure the
castors in place—extend them until they rmly touch the oor.
Adjusting for Stability:
Ensure the feet are adjusted so that they make solid contact with
the oor to provide stability.

Voltage Requirements:
Always ensure that the compressor is supplied with the correct voltage as required.
Caution: Voltages lower or higher than the specied range can harm the refrigeration unit.
Electrical Safety:
All units must be connected to a grounded electrical outlet that is the correct size and has overcurrent
protection. For detailed electrical requirements, refer to the specications on the nameplate of the unit.
• Avoid overloading the outlet to prevent electrical hazards; use a dedicated outlet for your unit that is
grounded.
• Ensure your unit is plugged directly into its own outlet, without the use of extension cords.
• When not in use for extended periods, unplug the unit.
• Wait at least 10 minutes after unplugging before reconnection to protect the compressor.
• Do not alter the electrical cord in any way.
5
Start-Up
Connect the cabinet to the power source and begin testing the refrigerator, its lighting, and the
electronic controls.
The compressor and condenser fans are expected to run within two minutes after power-up.
Confirm their operation by listening for the compressor's activation and feeling for airflow from
the vent slots. These fans will cycle on and off based on temperature.
Loading Products
Attention: Wait for the unit to reach the set temperature before loading it with food.
Ensure there is ample space around all items for consistent cooling and efficiency.
Shelf Spacing and Loading:
• Ensure a minimum of 3 inches clearance above items on the top shelf.
• Avoid having products hang over the shelf's edge to keep doors closing correctly.
• Limit shelf weight to 44 lbs. to prevent deformation.
• If shelves begin to flex or bend, reduce the load.
Temperature Controller Operation:
To set or change the temperature:
1. Press the 'SET' button for 1 second to enter the set value.
2. When the display blinks, adjust the temperature with the 'UP' or 'DOWN' buttons.
3. Press 'SET' again to save the new temperature setting.
OPERATION
6
Always disconnect the unit from the power source before starting any maintenance or cleaning.
Never handle the power cord with damp hands.
Cleaning the Condenser Coil
• For the unit to run efficiently, it's crucial to keep the condenser coil clear of dust, dirt, and lint.
• Monthly cleaning of the condenser coil and fins is advised for optimal performance.
• Use a commercial condenser coil cleaner, which you can find at kitchen equipment stores.
When cleaning, brush the fins vertically, from top to bottom, rather than horizontally.
• If any fins are bent, gently realign them using a fin comb tool.
Cleaning the Fan Blade and Motor
If needed, gently wipe the fan blades with a soft cloth. To prevent any moisture-related damage,
make sure to shield the fan motor during cleaning.
Cleaning the Interior of the Unit
• For the interior, use a gentle solution of warm water and mild soap.
• Avoid using harsh materials like steel wool, caustic cleaners, abrasive cleaning agents, or
bleach, as these can harm the stainless steel surfaces.
• Regularly clean the door gaskets, ideally on a weekly basis. Remove the gasket, wash with
soapy warm water for 30 minutes, rinse, and dry with a soft cloth before reattaching.
• After reattaching gaskets, check to ensure they are sealing correctly.
• Clean shelves and pilasters periodically by removing them and washing with a mild soap solu-
tion. To remove pilasters, first take out the shelves and their brackets, then lift the pilaster out.
