Place the refrigerator on a strong, level surface capable of supporting its weight (approximately 326 lbs empty, plus contents). Ensure adequate air circulation around the unit.

Avoid placing the unit in direct sunlight, near heat-producing equipment, or in areas with high humidity.

The unit is equipped with 4-inch casters for mobility. Ensure all casters are securely locked once the unit is in its final position to prevent accidental movement.

3.4 Initial Cleaning

Before first use, clean the interior and exterior surfaces with a mild soap and water solution. Rinse thoroughly and dry completely.

3.5 Power Connection

Connect the unit to a dedicated 115V/60Hz/1-ph electrical outlet with a NEMA 5-15P plug. The unit draws 2.1 amps. Do not overload the circuit.

3.6 Initial Startup

After placement and power connection, allow the unit to sit for at least 2 hours before turning it on. This allows the refrigerant to settle. Turn on the unit using the main power switch. The digital temperature controller will display the current internal temperature.

5.1 Cleaning the Interior

Regularly clean the interior with a mild, non-abrasive cleaner and warm water. Avoid harsh chemicals or abrasive pads that can damage surfaces. Rinse with clean water and dry thoroughly to prevent odors and bacterial growth.

Wipe down the stainless steel exterior with a soft cloth and a stainless steel cleaner or mild soap and water. Polish in the direction of the grain to avoid scratches. Do not use abrasive cleaners.

The condenser coil, located at the bottom of the unit, should be cleaned every 30 days or as needed to ensure efficient operation.
