4. Setup and Installation

4.1 Unpacking

• Carefully remove all packaging materials, including any protective films or tapes.
• Inspect the unit for any shipping damage. Report any damage immediately to the carrier and supplier.

4.2 Location

• Place the freezer on a strong, level surface capable of supporting the unit's weight when fully loaded.

• Connect the unit to a dedicated electrical circuit with the correct voltage and amperage as specified on the unit's data plate.
• Do not use extension cords or adapter plugs.
• Ensure proper grounding to prevent electrical shock.

4.4 Initial Startup

• After positioning and connecting power, allow the unit to sit for at least 2 hours before plugging it in. This allows refrigerants to settle.
• Plug in the unit. The compressor will start, and the interior lights will illuminate.
• Allow the unit to run empty for several hours (e.g., 4-6 hours) to reach its operating temperature before loading products.

5. Operating Instructions

5.1 Temperature Control

• The freezer is factory-set to maintain approximately -10°F (-23.3°C).
• Refer to the digital temperature controller (if equipped) for specific adjustment instructions. Typically, adjustments involve pressing 'SET' and using arrow keys.

5.2 Loading Products

• Load products evenly on the shelves. Do not block the air circulation vents inside the cabinet.
• Avoid overloading shelves beyond their weight capacity.
• Ensure products do not obstruct the closing of the doors.

5.3 Door Usage

• The doors are self-closing. Ensure they close completely after each use to maintain temperature and energy efficiency.
• Avoid leaving doors open for extended periods.
