Setup
1. Unpacking and Inspection
Carefully remove all packaging materials. Inspect the freezer for any shipping damage. Report any damage immediately to the carrier and your dealer. Do not discard packaging until the unit has been inspected and is operational.
2. Placement
This unit is designed for freestanding installation. Ensure the location has sufficient space for the door to open fully and for proper ventilation. Avoid placing the unit in direct sunlight or near heat-generating appliances. Maintain at least 4 inches of clearance from walls and other objects for optimal performance.
3. Leveling
The freezer comes with pre-installed casters for easy movement. Once in its final position, ensure the unit is level to prevent door misalignment and ensure proper drainage. Use a level and adjust the casters if necessary.
4. Electrical Connection
Connect the freezer to a dedicated 115 Volts, 60 Hz, single-phase, grounded electrical outlet. Do not use adapter plugs or extension cords. Ensure the circuit can handle the unit's power requirements.
5. Shelf Installation
The freezer includes 4 adjustable shelves. Install them by inserting the shelf clips into the desired slots on the interior pilasters and then placing the shelves onto the clips. Ensure shelves are level and securely seated before loading products.

6. Initial Cleaning
Before first use, clean the interior and exterior of the freezer with a mild soap and water solution. Rinse thoroughly and dry with a soft cloth. Do not use abrasive cleaners or solvents.
7. Initial Power-On
After connecting to power, turn on the main power switch located on the control panel. Allow the freezer to operate empty for at least 2-4 hours to reach its stable operating temperature before loading products.

Operating Instructions
1. Temperature Control
The freezer is equipped with a digital temperature controller. The current internal temperature is displayed on the screen. To adjust the set temperature, refer to the specific instructions for the Dixell controller model, typically involving pressing the 'SET' button and using the up/down arrows.
2. Interior Lighting
The interior LED lighting is controlled by a separate light switch on the control panel (refer to Figure 2). Turn the switch ON to illuminate the interior for product display and OFF when not needed to conserve energy.
3. Loading the Freezer
Load products evenly on the shelves, ensuring not to block the internal air vents or overload the shelves. Proper air circulation is crucial for maintaining consistent temperatures throughout the cabinet. Avoid placing hot items directly into the freezer.

Maintenance
1. Regular Cleaning
- Interior: Clean the interior regularly with a mild, non-abrasive cleaner and warm water. Remove shelves for thorough cleaning. Rinse and dry completely.
- Exterior: Wipe down the exterior surfaces with a soft cloth and mild detergent.
- Condenser Coils: The condenser coils, located at the bottom rear of the unit, should be cleaned every 30-60 days. Unplug the unit before cleaning. Use a stiff brush or vacuum cleaner to remove dust and debris. This is critical for efficient operation.

2. Defrosting
This unit features an automatic defrost system. However, if excessive ice buildup occurs, manual defrosting may be necessary. To manually defrost, turn off the unit, remove all products, and leave the door open. Once defrosted, clean and dry the interior before restarting.
3. Door Seal Inspection
Regularly inspect the door gasket for cracks or tears. A damaged gasket can lead to air leaks, increased energy consumption, and poor cooling performance. Clean the gasket with warm water and mild soap.
