1 IM SERVICE TRAINING Featuring the IM-51BAE 80041 9/9/99.
2 All IM models have similar sequence of operation. This manual is designed as a generic IM Training manual. The Hoshizaki IM series ice machine uses a horizontal evaporator design. This compact unit is designed for counter-top, under-counter, or free- standing installations.
3 This horizontal evaporator and water distribution system is unique to the IM series. The ABS water plate sprays water up into the evaporator cells to form the square IM cube. The moveable water pan assembly includes the water plate, reservoir pan, and pump motor assembly.
4 The front cam arm has a switch lever that operates the actuator toggle switch located above the pan assembly. The actuator toggle switch controls the direction of rotation for the actuator motor and energizes the pump motor during the freeze cycle.
5 The louver has a flip down cover to access the control switch. The switch has 3 positions. ICE, OFF, & WASH. The louver covers the compressor compartment. Remove the louver screws and lift the louver forward to access the condenser coil fan assembly and compressor.
6 The control box is accessed from the rear of the unit. Remove the screws holding the pipe cover and the control box cover to reach the control board and other components. A solid state board controls the IM operation. Several adjustments are included on the board.
7 The actuator motor turns counter clock wise to rotate the cam arms and lower the water pan away from the evaporator. When the water plate is completely down the switch lever moves the actuator toggle switch to the left. The board energizes the inlet water valve and condenser fan motor and de-energizes the hot gas valve.
8 The freeze cycle is controlled by a thermistor, which is mounted at the evaporator outlet. The pump is spraying water up into the evaporator cells to form the square IM cubes. The evaporator temperature lowers as the ice cubes form. A thermistor temperature of – 9.
9 The unit will continue through the freeze and harvest cycle until the bin control shuts down the refrigeration system. When pushed over, the bin control has a 10-second delay before shut down occurs. An 85-second delay occurs at startup when the bin control is released.
10 The maximum freeze timer is VR3. This timer will automatically switch the unit to the harvest cycle if the freeze cycle last longer than the setting time. The factory setting is 45 minutes. The defrost control VR2 will adjust the time period between ice-drop and actuator motor restart during harvest.
11 A red Service Indicator LED is also included on the control board. This LED will either light continually or flash to indicate a service fault. A fault diagnosis chart in the service manual will help the technician determine the actual problem. See chart next page.
12 FAULT DIAGNOSIS Check the status of the Service lamp on the Controller Board (LED-5) by removing the Control Box Cover. Lamp ON – Water Plate closed This tends to indicate the Back-up Timer has stopped machine operation during the freeze cycle. High ambient and water temperature are an obvious cause.
