3.3 Ice Type
The UYF0240W produces half-dice ice, which is a hard, clear ice cube with a unique rhomboid shape. These cubes are approximately 3/8" x 1-1/8" x 7/8" in dimension, with approximately 96 cubes per pound of ice. This ice type is ideal for various beverages, providing maximum cooling with a nearly 100% ice-to-water ratio.

5.1 Control Panel Functions
- Power Button: Turns the ice maker ON or OFF.
- Delay Button: Allows you to pause ice production for a set period (e.g., 4, 12, or 24 hours). Useful for managing ice supply during off-peak hours.
- Clean Button: Initiates the cleaning cycle. Refer to the Maintenance section for details.
- Full Bin Indicator: Illuminates when the ice storage bin is full, pausing ice production until ice is removed.
- Service Indicator: Illuminates to indicate a potential issue or a scheduled service reminder. Consult the Troubleshooting section or contact service.
5.2 Initial Startup
- Ensure all utility connections are secure and water supply is open.
- Plug the unit into a grounded electrical outlet.
- Press the Power button to turn the unit on. The ice maker will begin its initial startup sequence and start producing ice.
- Discard the first few batches of ice to ensure cleanliness.
5.3 Ice Retrieval
To retrieve ice, open the front bin door and use a clean, designated ice scoop. Do not use glass or other breakable containers to scoop ice.

6. Maintenance
Regular cleaning and maintenance are essential for optimal performance and hygiene.
6.1 Cleaning the Air Filter
The air filter should be cleaned regularly, typically every 2-4 weeks, depending on the operating environment. A dirty air filter can reduce efficiency and increase energy consumption.
- Turn off the ice maker and disconnect it from the power supply.
- Locate the air filter behind the front grille.
- Remove the air filter by pulling it out. This is a simple, tool-free process.
- Wash the filter with warm water and a mild detergent. Rinse thoroughly.
- Allow the filter to dry completely before reinserting.
- Reinstall the dry filter and restore power to the unit.

6.2 Sanitizing and Descaling
The ice maker requires periodic sanitizing and descaling to prevent mineral buildup and bacterial growth. The frequency depends on water quality and usage, but typically every 3-6 months. Use Manitowoc-approved cleaning solutions and follow the instructions provided with the cleaning kit. The Clean button on the control panel initiates this cycle.
Note: Always follow local health codes and regulations for ice machine maintenance.
7. Troubleshooting
Before contacting service, review the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No ice production | Unit not powered, water supply off, dirty air filter, high ambient temperature. | Check power, ensure water supply is open, clean air filter, verify operating environment. |
| Small or soft ice cubes | Low water pressure, dirty condenser, mineral buildup. | Check water pressure, clean condenser, perform descaling. |
| Service light illuminated | System error, maintenance reminder. | Consult the full service manual or contact a qualified service technician. |
| Excessive noise | Loose components, fan obstruction. | Inspect for loose parts, clear any obstructions from the fan. |
