3. Thread the four provided feet into the four holes in the bottom of the ice maker.

4. Move your ice maker to a location meeting all of the requirements of the Safety Information and Specification sections above: It should be firm, level, indoors, dry, and climate controlled to temperatures from 50–100°F or 10–40°C. It should be at least 6 inches or 15 cm from any obstruction in every direction and ideally 8 inches or 20 cm from any wall behind or beside it; away from direct sunlight; and nowhere near any sources of heat or any flammable, explosive, or corrosive substances or fumes. It should be near a source of clean drinking water; a dedicated compatible and grounded plug; and a dedicated drain or wastewater container. The rim of the container should be below the level of the drain. Using an elevated platform for the ice maker or having a sunken drain can improve draining speed.

5. Thoroughly clean the interior and exterior of the ice maker with a soft cloth. If you use a mild detergent, be sure you completely rinse any residue off the machine before any use.

6. Connect one of the water inlet hoses to the machine. Use the provided connecters and the other hose to extend the inlet if necessary.

7. Install the filter onto the water inlet hose using the provided screws and then connect the filter to a faucet in full compliance with local drinking water standards. Use the provided filter wrench to tighten the connections.
   DO NOT connect the ice maker directly to the water source without the filter and do not connect the filter to any sources of unsafe water.
   Water pressure should be between 15–72 psi or 1–5 bars. If your water pressure exceeds these values, a pressure reducing valve (not included) should be installed between your water source and the filter.

8. Place the end of the machine’s outlet pipe in your dedicated drain or wastewater container. To ensure proper drainage, make sure there is a gradual downward slope of at least 1 inch per yard or 2.5 cm per 1 m of drainage pipe, without any sharp turns or bends in the pipe.
   

9. Use the provided screws and a Philips head screwdriver to attach the filter bracket to a wall or other surface if applicable.

10. Connect the plug to its dedicated grounded outlet.

11. Fill the water tank with a mixture of 1 part water to 1 part vinegar or lemon juice. Press once to begin cleaning the device’s internal components. When the process is over, disconnect the ice maker from power and drain the used cleaning fluid completely.

12. Refill the water tank with pure water. Use the button to rerun the cleaning routine, rinsing the vinegar or lemon juice out of the system. When the process is over, disconnect the ice maker from power and drain the rinsing water completely.

Operation

**** For best results, do not activate the compressor or begin making ice for the first 24 hours after receiving your ice maker. This will allow time for its oil to drain completely back into its reservoir if it was disturbed during shipment.

Ice Making

1. Plug in the device and turn on its attached faucet.

2. Press The machine will turn on and the LCD display will light up, showing the version number “2003”. The compressor and circulating water pump should start running to initiate the icemaking process. Water should flow from the top of the ice tray into the water tank where it will slowly cool and freeze. As you progress through each step, the corresponding indicators should illuminate to indicate that they’re being executed properly. To move to the next mode early, press .
   **** If any error indicator lights up, refer to the troubleshooting section below.

3. Once the ice cubes have formed for the set amount of time, the machine will begin releasing ice.
   The reversing valve will open and the ice tray will heat up, causing the ice cubes to detach and fall down into the container below.

4. Once the ice bin falls below 75–80% full, the machine will reenter its icemaking mode and start forming the next batch of ice.

Adjusting Settings

1. To adjust the ice thickness, ensure the machine is in standby mode by pressing . The screen should show “OFF”. Hold down for about 15 seconds until the display shows a “1” followed by two numbers showing its current sensitivity current sensitivity level, which can be changed using and .
   The sensitivity level ranges from 01 to 20. Level 1 is suitable for water with high amounts of dissolved solids (TDS above 500 ppm), level 10 is suitable for moderate TDS levels ranging between 100 and 500 ppm, and level 20 is suitable for low TDS levels below 100 ppm. Selecting the lowest sensitivity setting for well water, a medium sensitivity setting for tap water, and the highest sensitivity setting for purified or filtered water will usually provide the best results.

2. Press again to change the precooling time, the amount of time the machine cools the water before making ice. The display should show a “2” followed by two numbers showing its current precooling time. A setting of “00” completely deactivates precooling. The maximum precooling time is 120 seconds.
   The longer the precooling time, the thicker and clearer the ice cubes will be. The recommended precooling time depends on the purity of the water you are using. If you are using tap water, a precooling time of 30 seconds may be sufficient. If you are using well water or purified water, you may need to set the precooling time between 60 and 120 seconds.

3. Press a third time to adjust the maximum intake time setting, which controls the duration of time that water is allowed to flow into the ice machine’s freezing compartment. The display should show a “3” followed by two numbers showing its current precooling time. The minimum setting is 1 minute and the maximum is 45 minutes.
   The intake time determines the amount of water that is used to make each batch of ice cubes, and it can have an impact on the size and shape of the ice cubes that are produced. Shorter water intake times can produce smaller and more solid ice cubes, while longer intake times can produce larger and more porous ice cubes.

4. Press a fourth time to set the cleaning cycle. The display should show a “4” followed by two numbers. A setting of “00” disables automatic cleaning, while a setting of “01” enables it. See Automatic Cleaning below for details.

5. Press a fifth time to adjust the drainage activation setting. The display should show “5-01”, showing drainage is enabled. Never change this value to avoid damage to your machine and to prevent excessive microbial growth.

6. Press a sixth time to reach the drainage frequency. The display should show a “6” followed by two numbers. Showing the number of icemaking cycles between each draining period. A setting of “00” completely deactivates the drainage cycle and should never be used. A setting of “1” activates draining after each icemaking session. The maximum number of sessions between draining is 20, but this should only be used in extremely hot, dry, and well-ventilated locations.

7. Press at any time to exit the settings menu while saving your changes. Alternatively, you can wait for 10 seconds without making any adjustment to exit the settings menu while saving your changes as well.

Delayed Start

1. Press to enter standby mode. The display should read “OFF”.
2. Press to enter the delayed start setup. The display should show a timer.
3. Use and to increase or decrease the timer in 10-minute increments.
4. When your delay is correct, press to save your changes and start the countdown.
5. When the countdown reaches zero, the machine will begin its ice making mode.
