N0922L, N1322L, F1222L, F1522L Remote Low Side Service Manual Includes Prodigy Plus Water The water supply for ice making must be cold, potable water. There is a single 3/8” male flare potable water connection on the back panel. Backflow The design of the float valve and reservoir prevents potable water backflow by means of a 1" air gap between the reservoir's maximum water level and the float valve water inlet orifice. Drain There is one ¾” FPT condensate drain fitting at the back of the cabinet.

N0922L, N1322L, F1222L, F1522L Remote Low Side Service Manual Includes Prodigy Plus 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.
N0922L, N1322L, F1222L, F1522L Remote Low Side Service Manual Includes Prodigy Plus Electrical Sequence with Condensing Unit Pushing and releasing the On button starts the machine. The sequence of operation begins with water. Water must be sensed or the controller will not start the ice making process. If there is no water, a 3 will show it the code display. If there is water, and there is nothing blocking the infrared beam of the ice sensors, the controller will start the machine.
N0922L, N1322L, F1222L, F1522L Remote Low Side Service Manual Includes Prodigy Plus 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.
N0922L, N1322L, F1222L, F1522L Remote Low Side Service Manual Includes Prodigy Plus Remote Refrigeration with Condensing Unit A condensing unit's compressor concentrates the heat from ice making into high pressure, hot discharge gas. The high pressure forces the gas to the 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.
N0922L, N1322L, F1222L, F1522L Remote Low Side Service Manual Includes Prodigy Plus 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.
N0922L, N1322L, F1222L, F1522L Remote Low Side Service Manual Includes Prodigy Plus Scale removal Note: Following this procedure will reset the de-scale and sanitize light. 1. Remove front panel. 2. Push and release the Off button. 3. Remove ice from bin or dispenser. 4. Turn the water supply to the ice machine OFF. 5. Drain the water and evaporator by disconnecting the leg of the hose connected to the water sensor and draining it into the bin. Return the hose to its original position. 6.

N0922L, N1322L, F1222L, F1522L Remote Low Side Service Manual Includes Prodigy Plus Auger and Evaporator Inspection The auger must be carefully inspected for wear and scale. There are also wear areas like the top bearing surface and the edges of the flights. The edges of the auger have horizontal serrations and highly machined areas in between. If the auger has contacted the evaporator wall, it will have very rough flight edges and should be replaced. Scale forms on the auger during normal ice making.
