- Add Water: Open the lid and pour potable water into the reservoir. Do not exceed the maximum fill line. The capacity is approximately 1.1 liters (0.3 gallons).
- Power On: Plug the ice maker into a grounded electrical outlet. Press the 'Ice/Clean' button once to start the ice making cycle. The 'Ice Making' indicator will illuminate.
- First Batch: The first batch of ice may take slightly longer, approximately 7 minutes. Subsequent batches will be produced continuously.
- Ice Full Indicator: When the ice basket is full, the 'Ice Full' indicator will light up, and the ice making process will pause. Remove ice to resume production.
- Add Water Indicator: If the water level is too low, the 'Add Water' indicator will light up. Add more water to the reservoir, and the ice maker will automatically resume operation.
6.2 Nugget Ice Characteristics
Your COWSAR ice maker produces soft, chewable nugget ice, also known as pellet ice. This type of ice is known for its unique texture and ability to cool beverages effectively without diluting them quickly.

7.2 Regular Cleaning
For optimal performance and hygiene, perform regular cleaning:
- Daily: Wipe down the exterior with a soft, damp cloth.
- Weekly: Remove the ice basket and clean it with warm, soapy water. Clean the interior of the ice bin and water reservoir with a soft cloth.
- Monthly (or as needed): Descale the unit, especially if you live in an area with hard water.
7.3 Descaling
Mineral deposits from hard water can affect ice quality and machine performance. Descale your ice maker monthly if you live in an area with hard water.

- Unplug the ice maker and drain all water from the reservoir.
- Prepare a descaling solution using white vinegar or a commercial descaling agent suitable for ice makers, following the product's instructions.
- Pour the solution into the water reservoir.
- Run the self-cleaning cycle (refer to Section 7.1).
- After the cycle, drain the solution completely.
- Rinse the reservoir thoroughly by filling it with clean water and running the self-cleaning cycle again, then draining. Repeat this rinsing process 2-3 times to ensure no descaling solution remains.
