• Rattling noises from refrigerant flow or water lines. Items stored on the unit can also cause noise.
• The compressor may make a pulsating or high-pitched sound.
• Splashing sounds from water running between the tank and evaporator.
• Gurgling sound at the end of a cycle due to refrigerant flow.
• 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, as the unit performs a rinse cycle.

Preparing the Ice Maker for Long Storage

If the ice maker will not be used for a long time or will be moved:

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 at the main water supply.
4. Disconnect the water supply hose from the water inlet valve.
5. Drain the water tank by pulling out the drainage cap (G). Reinstall the cap afterward.
6. Drain water from the unit's back drain port (⑧).
7. Disconnect the water drain pipe from the main drain pipeline or floor drain.
8. Open the door to allow for circulation and prevent mold and mildew.
9. Leave the water supply hose and power cord disconnected until ready for reuse.
10. Dry the interior and wipe the exterior.
11. Place a plastic bag on the unit to protect it from 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-based cleaners, as they may cause cracks on plastic parts.
• Have the condenser checked and cleaned by a trained service person at least once a year.
• This appliance must be cleaned using a water jet.

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

Periodic cleaning and maintenance ensure efficiency, performance, hygiene, and longevity. Adjust intervals based on usage conditions.

What shouldn't be done

Never store items other than ice in the ice storage bin, as they can be unsanitary and obstruct the drain pipe.

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 spotting.

Stainless steel models may discolor when exposed to chlorine gas. Clean with mild detergent, warm water, and a damp cloth. Never use abrasive cleaning agents.

NOTICE: Discoloration of stainless steel due to chlorine gas exposure (e.g., in areas with spas or swimming pools) is normal.

Interior Cleaning

For Ice Storage Bin

Sanitize the ice storage bin occasionally, especially before first use or after extended periods of non-use. It's convenient to sanitize after cleaning the ice-making system 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). Waste water will drain through the drain pipe.
3. Rinse thoroughly with clear water.
4. Reconnect power.

Wash the ice scoop regularly, like any other food container.

WARNING: DO NOT use solvent cleaning agents or abrasives on the interior, as they may transmit taste to ice cubes or damage the interior.

Ice Making Parts Cleaning

Periodically clean the main system components:

1. Repeat the cleaning steps for the water tank and other inner parts.
2. Pay special attention to the water dividing pipe on the evaporator. If water flow is very small or absent, discharge and clean this pipe carefully, ensuring all holes are clear. Reinstall after cleaning (power off first, then remove the front panel).
3. If ice cubes on the evaporator surface do not fall easily, do not force them. Press "ON/OFF" for more than 5 seconds to enter the ice melting process. After ice melts, turn off the unit and unplug to clean the evaporator surface.
4. Clean the water tank and ice-full detecting plate to maintain ice hygiene. Spray with a neutral cleaner and water mixture, wipe with a clean cloth, rinse with clean water, and dry. Drain the tank afterward.

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

Ice Making Assembly System Cleaning (Using Nu-Calgon Nickle Safe Ice-machine Cleaner)

Minerals in water can form scaly deposits. Regular cleaning removes this buildup. Cleaning frequency depends on water hardness (e.g., every 6 months for water with 4-5 grains/liter).

1. Turn off the ice maker. Keep it connected to water supply and drainpipe, but shut off the main water faucet.
2. Open the door and scoop out all ice cubes.
3. Remove the front panel.
4. Mix the cleaning solution: 400 ml Nu-Calgon Nickle Safe Ice-machine Cleaner with 3.8 liters warm water (120°F-140°F). Divide into two cups.
5. Ensure the water drainage cap of the water tank is properly installed. Pour one cup of the cleaning solution into the water tank and wait 5 minutes.
6. Turn on the power, then press "TIMER CLEAN" for more than 5 seconds to enter the self-cleaning program. The machine will start self-clean after water is enough. The cleaning symbol revolves on the LCD, displaying "90" countdown time. It stops after 90 minutes. Pressing "TIMER CLEAN" cancels the program.
7. This process rinses the water dividing pipe, evaporator, water pump, silicone pipe, and water tank.
8. After self-cleaning, drain the cleaning solution from the water tank into the lower ice storage bin. Shake slightly to drain completely. Reinstall the water drainage cap.
9. Repeat steps 6-8 two more times.
10. Clean the ice storage bin following the program.
11. After the special cleaning program, return to regular ice-making mode. Discard the first batch of ice.
