IMPORTANT SAFETY
When using electrical appliances, basic safety precautions should be followed to
reduce the risk of fire, electric shock, and injury to persons or property. Read all
instructions before using any appliance.
Use this appliance only for its intended purpose as described in this owner’s manual.
This ice-maker must be properly installed in accordance with the installation instructions before it is
used.
This unit must be positioned so that the plug is accessible. Do not run cord over carpeting or other heat
insulators. Do not cover the cord. Keep cord away from traffic areas, and do not submerge in water. No
other appliance should be plugged into the same outlet, and be sure that the plug is fully inserted into
the receptacle.
We do not recommend the use of extension cord as it may overheat and cause a risk of fire. If you must
use an extension cord, No.14AWG minimum size and rated no less than 1875 watts.
If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a
similarly qualified person in order to avoid a hazard.
Disconnect the mains plug from the supply socket when not in use for a long term, where supply
connection is via mains plug.
Remove power plug or disconnect from the mains before cleaning or servicing the appliance. NOTE: If
for any reason this product requires service, we strongly recommend that a certified technician perform
the service.
Never unplug you unit by pulling on the power cord. Always grasp the plug firmly and pull straight out
from the outlet.
Do not use your unit outdoors. Keep the unit away from direct sunlight and make sure that there is at
least 15 cm of space between the back of your unit and wall and keep the front free. Keep ventilation
opening in the appliance enclosure or in the built-in structure, clear of obstruction.
Do not tip over the unit which will cause abnormal noisy and make the ice-cube size abnormal. And
seriously, it may cause water leakage from the unit.

If the unit is brought in from outside in the winter season, give it a few hours to warm up to room
temperature before plugging it in.
Do not use other liquid to make the ice-cube other than water.
Do not clean your ice maker with flammable fluids. The fumes can create a fire hazard or explosion.
