IMPORTANT: • Although the unit has been tested and cleaned at the factory, due to long-term transit and storage, the first batch of cubes must be discarded. • Never turn the water supply tap off when the ice maker is working. • Never touch the evaporator when unit is running! • Except to take ice from the unit, keep the door closed to reduce melting and insure proper ice formation. How the machine makes ice Set the ON/OFF button to the ON position. The machine will automatically go to the ice making stage. There are two distinct cycles: ice making and harvest. The freeze cycle happens when water flows to the evaporator surface. The harvest cycle is when the ice is released and water enters the machine. A complete cycle takes about 20 minutes, but it depends on temperature and operating conditions. Freeze: During the freeze cycle the compressor is pumping refrigerant, the fan motor is blowing air, and the water pump is circulating water. When the batch of ice has been fully formed, the ice maker stops the freeze cycle and the harvest cycle begins. Harvest: During the harvest cycle the compressor is still operating, but the water pump has stopped. The hot gas valve opens, diverting hot refrigerant gas into the evaporator. The hot refrigerant gas warms the evaporator, causing the cubes to slide as a unit off the evaporator and into the storage bin. The freeze cycle will restart when all the cubes have been harvested. How the machine uses the water The ice maker begins with a fixed charge of water that is contained in the water trough. As the water flows to the freezing evaporator surface, the portion of water that does not contain mineral impurities freezes and sticks to the ice cube molds. The water containing impurities falls back into the water trough. During the ice making process, fresh water enters into the water trough continuously as the water in the trough freezes continuously in the evaporator. Normal sounds Your new ice maker may make sounds that are not familiar to you. Most of the new sounds are normal. Hard surfaces like the floor and walls can make the sounds louder than they actually are. The following list describes the sounds that might be new to you and what may be causing them. • Rattling noises may come from the flow of the refrigerant or the water line. Items stored on top of the ice maker can also make noises. • The high efficiency compressor may make a pulsating or high-pitched sound. • Water running may make a splashing sound. • You may hear air being forced over the condenser by the condenser fan. • During the harvest cycle, you may hear the sound of ice cubes falling into the ice storage bin. 14
