ICE MAKER SAFETY Your safety and the safety of others are very important. We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety messages. This is the Safety Alert Symbol. This symbol alerts you to potential hazards that can injure or kill you and others. All safety messages will follow the Safety Alert Symbol and either the words “DANGER”, “WARNING” OR “CAUTION”.
Plug into a grounded 3-prong outlet. Do not remove grounding prong, do not use an adapter, and do not use an extension cord. It is recommended that a separate circuit, serving only your ice maker, be provided. Use receptacles that cannot be turned off by a switch or pull chain. Do not connect or disconnect the electric plug when your hands are wet. Never unplug the ice maker by pulling on the power cord.
the first batch of cubes must be discarded. If the ice maker will not be used for a long time, before the next use it must be thoroughly cleaned. Follow carefully any instructions provided for cleaning or use of sanitizing solution. Do not leave any solution inside the ice maker after cleaning. DO NOT touch the condenser fins. The condenser fins are sharp and can be easily damaged. DO NOT use solvent-based cleaning agents or abrasives on the interior.

Ice Maker Installation Unpacking Remove packaging materials IMPORTANT: Do not remove any permanent instruction labels or the data label on your ice maker. Remove tape and glue from your ice maker before using, To remove any remaining tape or glue, rub the area briskly with your thumb. Tape or glue residue can also be easily removed by rubbing a small amount of liquid dish soap over the adhesive with your fingers. Wipe with warm water and dry.
Location Requirements This ice maker should be installed by qualified personnel. NOTICE: 1. Before setting the ice maker inside a cabinet, connect the water supply pipe correctly. Untie the drain hose, insert it into the drain, and connect the power supply line. 2. Do not kink or pinch the power supply line between the ice maker and wall or cabinet.
accordance with state and local codes. The unit should be located on a firm and level surface. It is important for the ice maker to be level in order to work properly. If needed, you can adjust the height of the ice maker by rotating the feet. See the Leveling the Ice Maker section. Electrical Requirements Before you move your ice maker into its final location, it is important to make sure you have the proper electrical connection.
Under block Turning the under block clockwise increases the machine’s height Turning the under block counter-clockwise reduces the machine’s height up It is important for the ice maker to be leveled, or water may not flow properly through the evaporator (ice mold). Ice production will be lower than normal, and operation will be noisy. Adjust the height of the under block of the adjustable foot, rotating it to the right (counter- clockwise) to lower that side of the ice maker.
6. Connect another water drain hose to bin drain line connection. Tighten firmly by hand, then one-half turn with wrench. 7. Turn on main water supply and tap. Check for water supply connection leaks. Tighten every connection (including connections at the water inlet). NOTE: If using a water filter, be sure to follow the filter manufacturer’s directions. Installation Types This ice cube machine has been designed to be enclosed (as under a cabinet).
sides for proper air circulation? 8. Has the power supply voltage been checked or tested against the nameplate rating? And has proper grounding been installed for the ice cube machine? 9. Is the ice cube machine plugged in? 10. Have you turned on the main water supply and the tap? 11. Have you checked for leaks at all water supply connections? Operating Method 1．Turn on the water tap, letting the water enter the water tank, then turn the power switch ON.
Freeze: During the Freeze cycle the compressor is pumping refrigerant, the fan motor is blowing air, and the water pump is circulating water. When the batch of ice has been fully formed, the ice maker stops the Freeze cycle and begins the Harvest cycle. Harvest: During the Harvest cycle the compressor is still operating, power is supplied to the water purge valve and hot gas valve.
Preparing the Ice Cube Machine for Long Storage If the ice cube machine will not be used for a long time, or it is to be moved to another place, it will be necessary to drain the system of water. 1. Shut off the water supply at the main water source. 2. Disconnect the water supply line from the water inlet. 3. Shut off the power supply at the main electrical power source. 4. Screw off the water tank screw nut and drain out water completely, then tighten the nut after finishing. Dry the tank. 5.
Exterior Cleaning The door and cabinet may be cleaned with a mild detergent and warm water solution such as 1 oz of dishwashing liquid mixed with 2 gallons of warm water. Do not use solvent-based or abrasive cleaners. Use a soft sponge and rinse with clean water. Wipe with a soft clean towel to prevent water spotting. Clean stainless steel with a cloth dampened with a mild detergent and warm water solution. Never use an abrasive cleaning agent.
detergent such as dishwashing liquid. After removing the dirt and lint from the surface, rinse the tube with clean water. 5. Replace the distribution tube. 6. Reconnect the water supply and power supply lines. 7. Re-attach the top panel. Ice-Making System Cleaning Minerals that are removed from water during the freezing cycle will eventually form a hard, scaly deposit in the water system. Cleaning the system regularly helps remove the mineral scale buildup.
7. The dirty water must be drained out completely. Perform steps 2 and 3 in the Interior Cleaning section. 8. Repeat steps 4 to 7 above three times with fresh water to rinse the ice-making system completely. NOTE: Do not add any cleaning or sanitizing solution to the water trough during the rinses. 9. If you want to make ice cubes after cleaning, turn off the power switch, drain off the waste water, then turn on the power switch. The next ice-making cycle will begin. 10. Discard the first batch of ice..
4. If the Clean button is pressed during the ice-making mode, it will be ignored. The ice-making will continue. 5. When you want to clean the machine, turn off the power switch first, then turn it on again. Press the Clean button within 3 minutes and the ice maker will start the cleaning mode, with harvest and ice-making indicators blinking. After 30 minutes, the cleaning mode stops and the harvest indicator and ice-making indicators are on steady.
Troubleshooting Before Calling for Service If the unit appears to be malfunctioning, read through the OPERATION section of this manual first. If the problem persists, check the Troubleshooting Guide below and on the following page. The problem may be something very simple that can be solved without a service call.
roblem The machine doesn't operate The water doesn't feed in after the ice maker starts. Machine makes ice, but bin does not fill up with ice Water is leaking out the unit. Cubes are partially formed--are white at the bottom. Noise during operation The icemaker stops suddenly while making ice. The body of the ice maker is electrified Scales occur frequently inside the machine. The ice cubes are not completely formed when being dumped. Possible Cause The ice maker is unplugged.
