This Stirling 145L Chest Freezer is a dual-function appliance that can operate as a freezer or a refrigerator. Important: Before plugging in the unit for the first time, let it stand upright for at least 4 hours to allow refrigerant gases to settle. When first starting, allow the unit to cool on the coldest setting for at least 2 hours before adding food.
Safety instructions
- Flammable refrigerant: This appliance contains R600a refrigerant and cyclopentane insulation blowing gas. Keep away from heat, sparks, and open flames.
- Ventilation: Ensure adequate air circulation around the appliance to prevent overheating.
- Child safety: When discarding the freezer, remove the lid to prevent child entrapment.
- Electrical: Do not use extension cords or adaptors. Ensure the power outlet is properly earthed.
Installation
- Clearance: Allow at least 10cm of clear space at the back and sides, and 1m above the unit.
- Surface: Place on a sturdy, level floor. Use the levelling feet at the front corners if necessary.
- Environment: Install in a well-ventilated indoor area, away from direct sunlight and heat sources.
Operation and control panel
The control panel is located at the bottom right-hand corner of the cabinet.
- Fridge mode: Adjustable between 2°C and 6°C. Suitable for short-term storage of fresh food.

Defrosting and cleaning
Frost will accumulate on the interior walls over time. When it reaches 3-4mm thickness, the unit should be defrosted.
- Unplug the freezer and remove all food and the storage basket.
- Open the two drainage plugs: one on the bottom of the front panel and one at the bottom of the interior cabinet.
- Place a tray and towels under the outer drain plug. Pull the plug slightly and rotate it 180 degrees to allow water to drain.
- Once defrosted, clean the interior with a mild detergent and water solution (baking soda is recommended).
- Dry thoroughly before restarting.
Troubleshooting
If the freezer does not work, check the power connection, fuse, or circuit breaker. If the compressor cycles frequently, ensure the lid is sealing properly and the unit has adequate ventilation. If the temperature is too warm, check the thermostat setting and ensure the lid is not opened too frequently.
