• Ensure the unit is secure on a level work surface by pressing down on the four (4) corners of the unit, creating a strong suction to the work surface.
• As a safety feature, a built-in program will shut power off to the motor if the tray is prevented from rotating, or the unit is overloaded beyond its recommended weight capacity and displays an E4 error.
• If the load is within specifications and centered on the tray and an E4 error persists, disabling the Overload Detection feature in the Menu may resolve this fault.
• Built-in memory maintains the last used speed and time settings during a power interruption.
• Avoid cold starts. The unit is not designed to start after being in a cold room environment. Bring the unit into the cold room from a room temperature environment, operate and remove the unit from the cold room as soon as the operation is complete
