Operation Your Unit

The Ice-making Process

1. Turn on the ice machine by plugging in the power. The power symbol [⚡] will flash. Press "ON"/"OFF". The outlet tube inputs water from the tank via a magnetic valve. The machine starts self-clean after sufficient water is supplied. The [?] symbol will revolve on the LCD. After 50s of cleaning, it drains water, adds water, and cleans again. Pressing "Timing/Cleaning" cancels the process. After cleaning, the [?] symbol rotates, indicating ice making. Ambient temperature is displayed (e.g., "80F"). Flashing numbers indicate remaining time (e.g., "10M" for 10 minutes). The machine may enter automatic cleaning after initial startup or after 20+ ice-making cycles.
2. After each ice-making cycle, a deicing process occurs. The [❄️] symbol flashes. Water is added to the tank via an electromagnetic valve. The [?] symbol flashes until the water reaches the standard level, then the [?] symbol extinguishes. The unit enters the next ice-making cycle. If the water level is not reached, the [?] symbol remains bright, and the unit stops working. In case of water shortage, restart the unit or it will restart automatically after 15 minutes. Each ice-making cycle is 11-20 minutes, influenced by ambient and water temperatures. The first cycle may be longer due to high water temperature, but will not exceed 35 minutes.
3. Adjust Ice Thickness: Press "+" or "-" buttons. The number in the bottom left of the display is the ice-making time setting (default "0"). Pressing "+" adds one minute, making ice thicker. Pressing "-" reduces time, making ice thinner. Restarting the machine resets to default "0". The setting affects the next ice-making cycle only.
4. When the [?] symbol lights up, the machine stops working. It resumes after ice is removed.
5. Shut down the unit: While making ice, press "ON/OFF" to enter standby mode. Pressing "ON/OFF" longer than 5 seconds during ice-making initiates the deicing process. Press "ON/OFF" again to turn off the machine.
6. Timing setting: Range is 1-24 hours. You can set a timed shutdown while running or a timed startup (ON-TIMER) when on standby. To set timing, press "TIMER". The default is "1H". Use "+" or "-" to adjust. The "H" symbol flashes during adjustment and becomes solid after 5 seconds of inactivity, indicating the timer is set. In standby, "5H" means automatic start after 5 hours. In ice-making, "5H" means automatic shutdown after 5 hours. The "H" display counts down.
7. Cancel timing: Press the "TIMER" button when a time is displayed (XX H). The timing is canceled when the number and "H" extinguish. The display area switches between timing and ice-making settings every 5 seconds.
8. Automatic self-cleaning program: Turn on the unit. Press "ON"/"OFF". Water enters the tank. The machine starts self-cleaning when water is full. The [?] symbol revolves on LCD, and "90M" is displayed. The program takes about 90 minutes and the system turns off automatically. Press "ON/OFF" to cancel.

Normal Sounds

Your ice maker may produce various sounds during operation. Most are normal. Hard surfaces can amplify sounds. Common sounds include:

• Swooshing sound when the water valve opens to fill the tank.
• Rattling noises from refrigerant or water flow, or from items stored on top.
• Pulsating or high-pitched sound from the compressor.
• Splashing sounds as water moves between the tank and evaporator.
• Gurgling sound due to refrigerant flow at the end of a cycle.
• Air being forced over the condenser by the fan.
• Sound of ice cubes falling into the storage bin during the harvest cycle.
• Continuous water running sound when first starting, due to a rinse cycle.

Preparing the Ice Maker for Long Storage

If the ice maker will not be used for a long time or is to be moved, drain all water from the system:

1. Allow all ice cubes to be ejected from the evaporator.
2. Turn off the unit and unplug the power cord.
3. Shut off the water supply.
4. Disconnect the water supply hose from the water inlet valve.
5. Drain the water tank by pulling out the water drainage cap (indicated as "G"). Reinstall the cap.
6. Drain water from the water drain port (indicated as "8").
7. Disconnect the water drain pipe from the main drain pipeline or floor drain.
8. Leave the door open for circulation to prevent mold and mildew.
9. Leave the water supply hose and power cord disconnected until reuse.
10. Dry the interior and wipe the outside of the unit.
11. Place a plastic bag on the unit to resist dust and dirt.

Cleaning & Maintenance

WARNING: Before any cleaning or maintenance, unplug the ice maker from the main power supply (except for the self-cleaning program). Do not use alcohol or fume for cleaning, as it may cause cracks in plastic parts. Ask a trained service person to check and clean the condenser annually. This appliance must be cleaned using a water jet.

CAUTION: If the ice maker has been left unused for a long time, it must be thoroughly cleaned before next use. Follow cleaning instructions carefully. Do not leave any cleaning solution inside the ice maker.

Periodic cleaning and maintenance ensure efficiency, performance, hygiene, and longevity. Maintenance intervals depend on water hardness and usage conditions.

Exterior Cleaning

Clean the door and cabinet with a mild detergent and warm water solution (e.g., 28g dishwashing liquid in 7.5L warm water). Do not use solvent-based or abrasive cleaners. Use a soft sponge, rinse with clean water, and wipe with a soft towel to prevent water spots. Stainless steel models may discolor when exposed to chlorine gas; clean them with a mild detergent and warm water, and a damp cloth. Never use abrasive agents.

Interior Cleaning (For Ice Storage Bin)

Sanitize the ice storage bin occasionally, especially before first use or after extended periods of non-use. It is convenient to sanitize after cleaning the ice-making system and when the bin is empty.

1. Disconnect power.
2. Wipe the interior with a sanitizing solution (28g household bleach or chlorine in 7.5L hot water, 95°F-115°F).
3. Rinse thoroughly with clear water; waste water drains through the drain pipe.
4. Reconnect power.

The ice scoop should be washed regularly like any other food container.

Ice Making Parts Cleaning

Periodically clean main systems exposed to water or ice:

1. Clean the water tank and other inner parts.
2. Clean the water dividing pipe on the evaporator. If water flow is small or absent, discharge and clean this pipe, ensuring all small holes are clear. Power off before cleaning and remove the front panel if necessary.

Suggestion: After cleaning interior parts and reassembling, discard the first batch of ice.

Ice Making Assembly System Cleaning

Minerals in water can form scaly deposits. Regular cleaning helps remove buildup. Frequency depends on water hardness (e.g., every 6 months for hard water).

1. Turn off the ice maker. Keep it connected to water supply and drainpipe.
2. Open the door and scoop out all ice cubes.
3. Remove the front panel.
4. Prepare cleaning solution: Mix Nu-Calgon Nickle Safe Ice Machine Cleaner with water.
