N0422, F0522, N0622, F0822, N0922, F1222, N1322, F1522 Air, Water or Remote Service Manual Sequence of Operation The ice machine’s function is to continuously produce ice until the ice level control senses that there is enough ice in the bin or dispenser. There are three systems that operate in close coordination to make ice. They are the electrical system, the water system and the refrigeration system.
N0422, F0522, N0622, F0822, N0922, F1222, N1322, F1522 Air, Water or Remote Service Manual Refrigeration System The refrigeration system is monitored by the high pressure cut out switch. If the refrigeration discharge pressure exceeds the pre-set point of the switch, it will open, causing the controller to shut the machine off. The discharge pressure control is an automatic reset switch, and after the discharge pressure drops, the controller will restart the unit.
N0422, F0522, N0622, F0822, N0922, F1222, N1322, F1522 Air, Water or Remote Service Manual Water System Water enters the machine through the 3/8" male flare at the rear of the cabinet, goes to the water reservoir which it enters through the float valve. The float valve maintains a constant level of water in the reservoir and evaporator, as water flows out the bottom of the reservoir tank to fill the evaporator. Reservoir overflow or evaporator condensation is routed to the drain.
N0422, F0522, N0622, F0822, N0922, F1222, N1322, F1522 Air, Water or Remote Service Manual Air Cooled Refrigeration The compressor concentrates the heat from ice making into high pressure, hot discharge gas. The high pressure forces the gas to the water cooled condenser. At the condenser, refrigerant gas flows through a serpentine tube that is connected to fins. Room air is forced by a fan motor through the fins.
N0422, F0522, N0622, F0822, N0922, F1222, N1322, F1522 Air, Water or Remote Service Manual Water Cooled Refrigeration The compressor concentrates the heat from ice making into high pressure, hot discharge gas. The high pressure forces the gas to the water cooled condenser. At the condenser, refrigerant gas and water flow through connected parallel tubes, but in opposite directions. Heat moves from the hotter discharge gas to the cooler water, and the refrigerant condenses into a liquid.
N0422, F0522, N0622, F0822, N0922, F1222, N1322, F1522 Air, Water or Remote Service Manual Remote Air Cooled Refrigeration The compressor concentrates the heat from ice making into high pressure, hot discharge gas. The high pressure forces the gas to the remote condenser. At the remote condenser, the discharge gas will either enter the coils or bypass them through the headmaster. The head master maintains a minimum discharge pressure to keep flash gas out of the liquid line.
N0422, F0522, N0622, F0822, N0922, F1222, N1322, F1522 Air, Water or Remote Service Manual How Ice Is Made Refrigeration effect is applied to the water between the auger and the evaporator. When that water's temperature drops to its freezing point, ice crystals form throughout it. A continually rotating auger moves the ice up the evaporator tube. At this point the ice is a soft ribbon that fills the space between the auger and evaporator.
