• Place the refrigerator on a strong, level surface capable of supporting its weight when fully loaded.
• Ensure adequate ventilation around the unit. Maintain a minimum of 6 inches (15 cm) clearance from walls or other obstructions to allow for proper airflow to the condenser.
• Avoid placing the unit near heat-generating appliances (e.g., ovens, fryers) or in direct sunlight, as this can reduce cooling efficiency and increase energy consumption.

4.1 Powering On

After connecting the unit to power, the digital temperature controller will illuminate. The unit will begin cooling automatically. Allow the refrigerator to operate for several hours empty to reach the desired temperature before loading products.

4.2 Digital Temperature Control

The unit features a digital temperature control system. The factory preset temperature range is 33°F to 38°F (0.5°C to 3.3°C). Refer to the separate controller manual (if provided) for detailed instructions on adjusting temperature settings and other parameters. Avoid frequent or drastic temperature changes.

5. Maintenance

WARNING: Disconnect power to the unit before performing any cleaning or maintenance.

5.1 Regular Cleaning

• Interior: Clean the interior regularly with a mild soap and water solution. Rinse with clean water and dry thoroughly to prevent odors and maintain hygiene. Remove shelves for easier cleaning.
• Exterior: Wipe down the stainless steel exterior with a soft cloth and a non-abrasive cleaner designed for stainless steel. Avoid harsh chemicals or abrasive pads that can scratch the surface.
• Glass Door: Use a glass cleaner to keep the door clear for optimal product visibility.

5.2 Defrosting

This unit features an air defrost system. However, if excessive ice buildup occurs, manual defrosting may be necessary. To manually defrost:

1. Remove all products from the refrigerator.
2. Turn off the unit and unplug it from the power outlet.
3. Leave the door open to allow ice to melt naturally. Do not use sharp objects to remove ice.
4. Once defrosted, clean and dry the interior thoroughly before restarting the unit.

5.3 Magnetic Door Gaskets

Regularly inspect and clean the magnetic door gaskets. Ensure they are free of food debris and remain flexible. A clean, intact gasket ensures an energy-efficient seal, preventing cold air loss. If gaskets are damaged or stiff, they should be replaced by a qualified technician.

5.4 Condenser Coil Cleaning

The bottom-mount compressor unit requires regular cleaning of the condenser coil. Dust and debris on the coil can reduce cooling efficiency and increase energy consumption. Clean the condenser coil every 30-60 days using a stiff brush or vacuum cleaner. Access to the coil is typically through the front grille at the bottom of the unit.
