  • Page 6: Safety Precautions

    SAFETY PRECAUTIONS To prevent personal injury, injury to others, or damage to property, read these safety precautions carefully before use. INJURY PREVENTION Do not cut, change or modify the power cable.* When removing the plug, hold onto the plug and not the cord. An ultra-low temperature freezer is qualitatively different than a home freezer.

    OPERATION Important changes to the freezer settings require sustained button pushes. This helps prevent accidental changes to the settings during transportation. Some sequences require a three-second button press and hold while other sequences require a five-second button press and hold. For example, Turning the freezer ON requires a three-second press and hold (two beeps).

  • Page 20: Error Codes

    ERROR CODES These are displayed in the LCD display as E ##. The free-piston Stirling engine is not maintaining a working temperature. This could arise from blocked filters, blocked air passages, unusually hot ambient temperatures (for example >45ºC), or a fan failure. Check air passages and clear any blockages for good air circulation.

  • Page 21: Maintenance

    MAINTENANCE CARING FOR YOUR FREEZER GASKET The temperature differential between ambient and the ultra-low interior can attract moisture near the gasket. For best results always wipe away moisture during openings to prevent ice accumulation. Do not use sharp instruments to scrape ice from the surface. AIR INTAKE FILTER Clean accumulated dust and dirt on the air intake filter every month.
