  • Page 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 which forms a square cube shape with a small dimple. 20mm...
  • Page 3 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. Tension springs connect two cam arms to the water plate assembly. An actuator motor rotates the cam arms to raise and lower the water pan during the ice making cycle.
  • Page 4 The horizontal evaporator and water distribution system are unique to the Hoshizaki IM series. The IM-500 makes ice on a horizontal evaporator and uses R-404a refrigerant. The IM-500SSA sequence of operation will be explained in the following pages.

  • Page 5: Soft Start

    This operation common among Hoshizaki cube icemakers. WATER PAN OPENS/HARVEST: During the initial harvest, the compressor, hot gas valve and the actuator motor starts to open, after 20 seconds the water valve will energize to supply defrosting water for a specified time.
  • Page 6 As soon as the pan starts to open the defrost backup timer starts, if the thermistor mounted on the evaporator does not reach the defrost completion temperature before the timer times out at 30 min. the display will show “E2” and the unit stops.
  • Page 7 WATER PAN CLOSES/FREEZE: When the water pan closes and the hall IC turns on the water valve opens to supply ice making water for a specific time. The supply time varies between startup, reset, and end of bin control cycle between partial flush and full drain.
  • Page 8 The IM-500SAA uses a mechanical bin control located on the right rear side of the ice drop zone. This control will open when ice pushes against the switch, if the switch stays open for more than 10 seconds the machine will start the bin control cycle, starts and the machine will shut down after the next defrost cycle.
  • Page 9 The control switch is marked “ICE- OFF-WASH” and is located on the upper right front of the unit. “OFF” – No power supplied to unit “ICE” – Starts the automatic Ice making process “WASH” – Power is supplied to water pump (this allows for cleaning and/or sanitizing “RESET”- If the reset is pushed after the...

    2. “00” will appear on the display of the new board 3. For the IM-500SAA, set the model code to “08” 4. Press service button “1” to increase the first digit and service button “2” to increase the second.
  • Page 11 Preventative maintenance: Follow these steps to allow the unit to operate efficiently. 1. Clean the condenser once a year using a brush or vacuum. 2. Check and clean the inlet water valve screen as needed to assure proper water flow. 3.
  • Page 12 1) Dilute approximately 7.2 fl. oz. (214 ml) of recommended cleaner Hoshizaki “Scale Away” with 0.8 gal. (3.0 lit.) of water. 2) Turn off the power supply. 3) Remove all ice from the storage bin. 4) Remove the front panel.
  • Page 13 14) Turn on the power supply to start the washing process. 15) Turn off the power supply after 30 minutes. 16) Open the icemaker water supply line shut-off valve. See Fig. 4. 17) Remove the front panel. 18) Move the control switch to the "ICE" position.
  • Page 14 Remove the front panel and top panel. Move the control switch to the “WASH“ position. Slowly pour the sanitizing solution over the top of the evaporator and into the water tank. Do not splash or spill the solution onto other parts. Replace the front panel and top panel in their correct positions.
  • Page 15 Replace the front panel. Clean the storage bin liner using a neutral cleaner. Rinse thoroughly after cleaning. Turn on the power supply to start the automatic ice making process.
  • Page 17 Electrical Specifications: The unit is 115 volt/ 60 hz./1ph. The IM-500SAA should be connected to a separate 20 Amp circuit.
  • Page 23 False 3. The bin control switch must OPEN or CLOSE to shut the unit down? 4. The IM series uses R-404A or R-134A refrigerant. 5. The IM-500SAA only uses one thermistor located on the evaporator? True False 6. The freeze cycle is temperature and time terminated.
