2. Setup and Installation
2.1 Unpacking
Carefully remove all packaging materials, including tape and protective films. Inspect the refrigerator for any shipping damage. Report any damage to your retailer immediately.
2.2 Placement
Place the refrigerator on a firm, level surface. Proper leveling is crucial for the efficient operation of the absorption cooling system. Use the adjustable feet to ensure stability.
Ensure adequate clearance around the unit for proper ventilation, especially at the rear where the cooling unit is located. This is vital for optimal performance and safety, particularly when operating on gas.

2.4 Initial Operation
After connecting to a power source, allow the refrigerator to operate empty for at least 4-6 hours to reach its stable operating temperature before loading with food items.
3. Operating Instructions
3.1 Control Panel Overview
The control panel is located at the top front of the refrigerator and features controls for power selection, temperature adjustment, and gas ignition.
Figure 3: The control panel features a transparent protective cover and clearly labeled controls for easy operation.
- Rotary Switch (F): Selects the power source (OFF, DC12, AC).
- Thermostat Knob (D): Adjusts the cooling temperature. Higher numbers indicate colder settings.
- Flame Indicator (A): Illuminates when the gas flame is active.
- Battery Switch (B): Used for igniting the gas burner.
- Safety Valve Button (C): Engages the gas safety valve during ignition.
3.2 Power Source Selection
Turn the Rotary Switch (F) to select your desired power mode:
- DC12: For 12V DC operation (e.g., vehicle battery).
- AC: For 110V AC operation (e.g., household outlet).
- Gas: For propane gas operation.
3.3 Temperature Adjustment
Rotate the Thermostat Knob (D) to set the desired cooling level. The temperature range is typically between 32°F and 50°F (0°C and 10°C). Adjust as needed for optimal food preservation.
3.4 Gas Operation (Ignition Procedure)
- Ensure the refrigerator is connected to a propane supply and the gas valve is open.
- Turn the Rotary Switch (F) to the 'Gas' position.
- Press and hold the Safety Valve Button (C).
- While holding (C), repeatedly press the Battery Switch (B) to ignite the burner.
- Observe the Flame Indicator (A). Once it illuminates, continue holding the Safety Valve Button (C) for approximately 10-15 seconds to allow the thermocouple to heat up.
- Release the Safety Valve Button (C). The flame indicator should remain lit, confirming successful ignition. If the flame goes out, repeat the process.
3.5 Adjustable Shelf
The refrigerator includes a sliding and removable shelf, allowing for flexible organization of your food and beverages. To adjust, simply slide the shelf out and reposition it to the desired height.
4. Maintenance
4.1 Cleaning
Regular cleaning helps maintain hygiene and efficiency.
- Interior: Clean with a mild detergent and warm water. Rinse thoroughly and dry. Avoid abrasive cleaners.
- Exterior: Wipe with a soft, damp cloth.
- Condenser/Cooling Unit (Rear): Periodically clean dust and debris from the cooling unit at the rear of the refrigerator to ensure efficient heat dissipation. Disconnect power before cleaning.
4.2 Defrosting
This refrigerator features an automatic defrost system, minimizing the need for manual defrosting. If excessive frost builds up, manually defrost by turning off the unit, emptying its contents, and leaving the door ajar until frost melts. Clean and dry the interior before restarting.
4.3 Long-Term Storage
If the refrigerator will not be used for an extended period:
- Empty all contents and disconnect from all power sources (AC, DC, and propane).
- Clean the interior thoroughly and leave the door slightly ajar to prevent odors and mold growth.
- Store in a dry, well-ventilated area.
5. Troubleshooting
If you experience issues with your refrigerator, consult the following table before contacting support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Refrigerator not cooling | No power supply; Incorrect power source selected; Unit not level; Insufficient ventilation; Gas supply off or empty. | Check power connections (AC/DC); Ensure gas valve is open; Select correct power mode; Level the unit; Clear ventilation areas. |
| Unusual noise | Unit not level; Obstruction near cooling unit. | Ensure unit is level; Remove any obstructions. (Note: This model features a perfectly silent absorption cooling system, so significant noise is unusual). |
| Gas flame not igniting | No gas supply; Ignition sequence incorrect; Faulty igniter. | Check gas supply and valve; Follow ignition procedure carefully; Contact service if igniter is suspected faulty. |
| Excessive frost buildup | Door not sealed properly; Frequent door opening; High humidity. | Check door seal; Reduce frequency of door openings; Perform manual defrost if necessary. |
