3.4 Door Reversibility

The refrigerator features reversible doors, allowing you to change the door swing direction to suit your installation needs. Consult a qualified technician for door reversal if you are unsure.

4. Operating Instructions

The VTR 5075 offers trimix operation, allowing it to run on 12V DC, 220V AC, or Gas.

4.1 Power Source Selection

The electronic control panel allows for manual selection of the desired energy source (12V, 220V, or Gas). Ensure the correct power source is connected and selected before operation.

• 12V DC Operation: Ideal for mobile applications (e.g., RVs, boats) when connected to a vehicle's battery.
• 220V AC Operation: For use when connected to a standard household or campsite electrical outlet.
• Gas Operation: For use when electrical power is unavailable. Ensure proper gas supply and ventilation. The electronic re-ignition system will automatically attempt to re-ignite the flame if it goes out.

4.2 Temperature Control

The electronic control panel includes a thermostatic adjustment feature. Use this to set the desired cooling temperature inside the refrigerator compartment. Allow several hours for the refrigerator to reach the set temperature after initial startup or significant temperature changes.

4.3 Freezer Compartment

The refrigerator includes a 2-star freezer compartment with a capacity of 8.2 liters, suitable for short-term storage of frozen goods.

5. Maintenance and Care

Regular maintenance ensures the longevity and efficient operation of your refrigerator.

5.1 Cleaning

• Always disconnect the refrigerator from all power sources (12V, 220V, and gas) before cleaning.
• Clean the interior and exterior with a soft cloth and a mild detergent solution. Do not use abrasive cleaners or solvents.
• Wipe down door seals regularly to ensure a tight seal.
• Clean the rear ventilation grilles periodically to ensure proper airflow for the absorption unit.

5.2 Defrosting

The freezer compartment will accumulate frost over time. Defrost the unit when the frost layer becomes approximately 5mm thick. To defrost:

1. Turn off the refrigerator and disconnect all power sources.
2. Remove all food items and place them in a cool place.
3. Leave the refrigerator door open to allow frost to melt naturally. You can place a towel at the bottom to absorb water.
4. Once defrosted, clean and dry the interior thoroughly before restarting the unit.

5.3 Winterization (for mobile applications)

If the refrigerator will not be used for an extended period, especially in cold temperatures, ensure all water lines (if applicable) are drained and the unit is clean and dry to prevent damage from freezing.

6. Troubleshooting

Before contacting service, check the following common issues:

• Refrigerator not cooling:
  • Check if the power source (12V, 220V, or Gas) is properly connected and selected.
  • Ensure the gas bottle is not empty and the gas valve is open.
  • Verify the temperature setting is appropriate.
  • Check for obstructions in the ventilation grilles.
• Excessive frost in freezer:
  • The door may not be sealing properly. Check door seals for damage or debris.
  • Frequent opening of the door.
  • High humidity in the environment.
• Gas flame not igniting:
  • Check gas supply.
  • Ensure the electronic re-ignition system is functioning. If not, professional service may be required.

If problems persist after checking these points, contact a qualified service technician.
