Do not turn the Ice Maker upside down. Doing so could cause the compressor or refrigerating system to operate incorrectly. 2 Remove packaging materials and dispose of appropriately by keeping out of reach of children.
WATER SUPPLY This Ice Maker has been specifically designed for portability allowing you to simply pour water into the Water Reservoir manually as required to make ice. However, the unit is also equipped with a Water Inlet valve at the rear of the Ice Maker, where a ¼” PE water inlet tube can be connected to a cold water line for continuous water supply. Please note an Ice Maker external water source Installation Kit is not supplied with this Ice Maker.

CLEANING AND MAINTENANCE CLEANING To keep your ice tasting fresh and your UltraSonic Nugget Ice Maker working at its best, we recommend cleaning your Ice Maker before first use and further at least once per week. 1 Take out the Ice Basket and Ice Scoop and hand wash only in warm water with mild detergent. Rinse and wipe dry. Do not use any solvents or chemicals. 2 Wipe the interior of the Ice Maker with a soft cloth soaked in warm water and white vinegar. Repeat with a clean damp cloth.
7 Reattach the Drain Plug to the Drain Tubes. Attach the Drain Plug back into the two slots at the back of the Ice Maker as illustrated in the “HOW TO USE” instructions earlier in this manual. 8 If the unit has been moved in this process, wait for 30 minutes for the unit refrigerant to settle. Repeat steps 3-7, this time using fresh, room temperature water only, to rinse the Water Reservoir and internal mechanisms.
DESCALING Depending on the water that you use in the Ice Maker, there may be signs of mineral build-up. Hard water residue may not always be visible but will impede ice production, and it is therefore recommended to descale the Ice Maker at least every 6 months. 1 Wipe the interior of the Ice Maker with a soft cloth soaked in warm water and white vinegar, including the Ice Level and Water Level Sensors.
