Emerson IM93B is a portable ice maker designed for home use. It features three ice cube sizes: small, medium, and large. The ice maker has a 110 - 120V, 60Hz power supply and a 5-inch minimum clearance is required at the rear and sides of the unit and 8 inches on top of the unit for proper ventilation. It is equipped with indicator lights that will notify you when the ice basket is full or when water needs to be added. The unit automatically stops working when the ice basket is full or when there is water shortage, and it will automatically restart when the water tank is refilled.
