Setup

1. Unpacking: Carefully remove the ice maker from its packaging. Inspect for any damage. Remove all packing materials, including any tape or protective films.

3. Initial Resting Period: After transport, allow the ice maker to stand upright for at least 24 hours before plugging it in. This allows the refrigerant to settle.
4. First Cleaning: Before first use, clean the interior of the ice maker. Refer to the "Maintenance" section for detailed cleaning instructions.
5. Add Water: Open the lid and fill the water reservoir with potable water up to the MAX fill line. Do not overfill.

Descaling (Hard Water Areas)

Hard water can lead to mineral buildup. Regular descaling is recommended to maintain performance.

• Moderately Hard Water Areas: Descale monthly.
• Hard to Very Hard Water Areas: Descale every two to three weeks.
• Suggestion: Using purified or bottled water can reduce mineral buildup.

To descale, use a descaling solution suitable for ice makers or a mixture of water and white vinegar. Follow the instructions provided with the descaling solution or use a 1:1 ratio of white vinegar to water. Run the self-cleaning cycle with the descaling solution, then drain and rinse thoroughly with clean water by running several self-cleaning cycles with only water.
