Water system the auger is driven at about 11 rpm by the gear reducer. The gear reducer is a sealed component and does not require lubrication, as it contains a charge of grease. The auger motor drives a set of gears that all together reduce the motor speed to the 11 rpm output speed and correspondin...

Storage the ice storage system is made up of a plastic lined ice storage bin, covered by an insulated top panel and an insulated swing open door with gasket. The ice storage bin is foamed in place, so the side panels are not removable. Page 6 gemu090 service ice making check water time to clean clea...

Ice capacity the rate of ice making is relatively fixed, it depends upon the heat load and the ambient temperature the machine is operating in. As either increase the amount of ice made will decrease. The machine will work to keep the ice bin full. A full bin of ice is when the ice level is even wit...
