WARNING, continued • Before servicing the icemaker, move the control switch to the "OFF" position. Unplug the icemaker from the mains socket. • Do not use an extension cord. • Do not use an icemaker with a damaged power cord. The power cord should not be altered, jerked, bundled, weighed down, pinched, or tangled. Such actions could result in electric shock or fire. To unplug the icemaker, be sure to pull the plug, not the cord, and do not jerk the cord. • The GREEN/YELLOW earth (ground) wire in the factory-installed power cord is connected to the icemaker. If it becomes necessary to remove or replace the power cord, be sure to connect the power cord's earth (ground) wire. • Do not make any alterations to the icemaker. Alterations could result in electric shock, injury, fire, or damage to the icemaker. • This appliance is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. • Children should be properly supervised around this appliance. • Do not climb, stand, or hang on the icemaker or allow children or animals to do so. Serious injury could occur or the icemaker could be damaged. • Do not use combustible spray or place volatile or flammable substances near the icemaker. They might catch fire. • Keep the area around the icemaker clean. Dirt, dust, or insects in the icemaker could cause harm to individuals or damage to the icemaker. NOTICE • Follow the instructions in this <strong>manual</strong> carefully to reduce the risk of costly water damage. • In areas where water damage is a concern, install in a contained area with a floor drain. • Install the icemaker in a location that stays above freezing. Normal operating ambient temperature must be within 45°F to 100°F (7°C to 38°C). • Do not leave the icemaker on during extended periods of non-use, extended absences, or in sub-freezing temperatures. To properly prepare the icemaker for these occasions, follow the instructions in "VI.C. Preparing the Icemaker for Periods of Non-Use." • Do not place objects on top of the icemaker. • The storage bin is for ice use only. Do not store anything else in the storage bin. 6
