2. Safety Information
Adherence to the following safety guidelines is crucial for preventing injury and damage to the unit. Always follow local codes and regulations.
- Electrical Safety: Ensure the unit is connected to a grounded 115V, 60Hz, 1-phase power supply with a dedicated circuit. Do not use extension cords. Disconnect power before any service or cleaning.
- Refrigerant: This unit uses R290 refrigerant. Servicing should only be performed by qualified personnel. Do not puncture the refrigerant lines.
- Ventilation: Maintain adequate clearance around the unit for proper airflow to the condenser. Blocked airflow can lead to reduced efficiency and unit failure.
- Placement: Install the unit on a level, stable surface capable of supporting its weight when fully loaded. Avoid direct sunlight or heat sources.
- Cleaning: Use only mild, non-abrasive cleaners. Avoid harsh chemicals that can damage surfaces or leave residues.
- Child Safety: Keep children away from the unit, especially during operation and maintenance.
3. Setup and Installation
3.1 Unpacking
Carefully remove all packaging materials. Inspect the unit for any shipping damage. Report any damage to the carrier immediately.
3.2 Placement
Position the refrigerator in a location with good air circulation. Allow at least 6 inches of clearance from walls or other obstructions for proper ventilation of the condenser coil. Ensure the floor is level and strong enough to support the unit's weight.

3.3 Installing Casters
The unit comes with four casters, two of which are locking. Attach the casters to the bottom of the unit using the provided hardware. Ensure the locking casters are positioned at the front for stability.
Figure 3: Installation of a locking caster.
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-phase electrical outlet. The unit is equipped with a NEMA-5-15P plug. Do not use adapters or extension cords.
Figure 4: NEMA-5-15P Power Plug.
3.6 Initial Startup
After connecting power, allow the unit to run empty for at least 2-4 hours to reach the desired operating temperature before loading products. This allows the refrigeration system to stabilize.
4. Operating Instructions
4.1 Temperature Control
The refrigerator is equipped with a digital LED temperature display and electronic thermostat. The factory preset temperature range is 36-43°F (2.2-6.1°C). To adjust the temperature:
- Press the "SET" button. The current set point temperature will flash.
- Use the Up (^) or Down (v) arrows to adjust the temperature.
- Press "SET" again to confirm the new setting.

4.2 Loading Products
Arrange products to allow for proper air circulation. Do not block the internal air vents. The unit features eight heavy-duty polyethylene-coated adjustable wire shelves for flexible storage.
4.3 Sliding Glass Doors
The two double-pane sliding glass doors are designed for smooth operation and are self-closing to minimize energy loss. Ensure doors close completely after each use. The unit includes a locking mechanism for securing contents.

4.4 Interior LED Lighting
The interior is illuminated by energy-efficient LED lighting, enhancing product visibility. The lighting can typically be controlled via a switch on the control panel or near the light fixture.
5. Maintenance
5.1 Regular Cleaning
- Interior: Clean regularly with a mild, non-abrasive cleaner and warm water. Rinse and dry thoroughly. Remove shelves for easier cleaning.
- Exterior: Wipe down the exterior with a soft cloth and mild detergent. Avoid abrasive pads or cleaners.
- Glass Doors: Use a glass cleaner for streak-free results.
5.2 Condenser Coil Cleaning
The condenser coil, located at the bottom of the unit, should be cleaned every 30 days or as needed. A dirty coil reduces efficiency and can lead to compressor failure. Disconnect power before cleaning. Use a stiff brush or vacuum cleaner to remove dust and debris.

5.3 Automatic Defrost
This unit features an automatic defrost system, eliminating the need for manual defrosting. Ensure the drain pan is clear and not overflowing.
5.4 Fan Maintenance
Periodically check the evaporator fan (located inside the unit) for obstructions or excessive dust buildup. Ensure it spins freely. Disconnect power before inspection.

6. Troubleshooting
Before calling for service, review the following common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit not cooling | Power supply issue, thermostat set too high, dirty condenser coil, blocked airflow. | Check power connection and circuit breaker. Adjust thermostat. Clean condenser coil. Ensure proper ventilation. |
| Excessive noise | Loose components, fan obstruction, unit not level. | Check for loose parts. Clear fan obstructions. Level the unit using the casters. |
| Excessive condensation inside | Door not closing properly, high humidity, frequent door openings. | Ensure doors are fully closed and seals are intact. Reduce frequency of door openings. |
| Light not working | Light switch off, LED bulb failure. | Check light switch. Contact service for bulb replacement if necessary. |
If the problem persists after attempting these solutions, please contact qualified service personnel.
