The Whynter IMC-490SS ice maker is equipped with a Self-Clean program that ensures your ice is 
clean and fresh by removing scales and impurities. This program works the same as the ice making 
process, only without the freezing.

the self-clean program which will take about 5-6 minutes. During this process, the icon  and will 
be displayed in LCD window, and the fan blade in the  icon will always rotate. This process will 
rinse the inside parts for several times. 
5. After self-clean program is completed, drain out the water by loosening the drain cap and unplugging 
the rubber drain plug on the side. Install the rubber drain plug once the water reservoir is empty.
