DANGER
1. Remove the exterior and interior packaging. Check that all the accessories are included
first. If any parts are missing, please contact our customer service.
2. Remove all the tape on the unit. Open the transparent window, take out the water filling
funnel and the plastic soft tube (if supplied).
3. Clean the interior with luke-warm water and a soft cloth.
4. The machine must be placed on a dry and level surface with sufficient ventilation, far from
heat sources such as ovens, heaters, and corrosive gases.
5. When the icemaker is moved or transported, please allow time for the fluids in the
compressor to settle. Before using the icemaker for the first time, please wait 2 hours after
the unit has been leveled and positioned in its proper place.
* Improper use of the grounded plug can result in the risk of electrical shock. If the
power cord is damaged please call our customer service.
1. This unit should be properly grounded for your safety. The power cord of this appliance is
equipped with a three-prong plug which plugs into standard three prong wall outlets to
minimize the possibility of electric shock.
2. Plug your appliance into an exclusive, properly installed, grounded wall outlet. Do not under
any circumstances, remove the third (ground) prong from the power cord. Any questions
concerning power and/or grounding should be directed toward a certified electrician.
3. This appliance requires a standard 115volt, 60Hz electrical outlet with three-prong ground.
Before using your ice maker, it is strongly recommended to clean it thoroughly.
Unplug the unit before cleaning or any maintenance.
1. Take out the water filling funnel and the plastic soft tube(if supplied).
2. Clean the interior with diluted detergent, warm water and a soft cloth. First pour the warm
water with diluted detergent into the internal water reservoir and the space below the
transparent window (Note: Place a container on the cover of the water drip tray first
because the water will flow out from the ice-cube tap), then use the soft cloth to wipe the
surface.
3. Again use the water to rinse the inside parts, and drain out the water by unplugging the
drain cap on the bottom.
4. The outside of the ice maker should be cleaned regularly with a mild detergent solution and
warm water.
5. Dry the interior and exterior with a soft cloth.
6. When the machine is not in use for a long time, open water drain cap to drain out water
completely from water reservoir.
