AM SERVICE TRAINING Featuring the IM-500SAA 80047 9/10/13.
2 20mm All IM models have similar sequence of operation. This m anual 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. A standard 120-volt power cord (field supplied) provides the electrical connection.
3 The ABS water plate sprays water up into the evaporator cells to form the square IM cube. The moveable water pan asse mbly includes the water plate, reservoir pan, and pump m otor assembly. Tension springs connect two cam arms to the water plate assembly.
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.
5 The IM-500SAA unit uses a combination thermistor and control board to control the sequence of operation. SOFT START: When the toggle switch is placed in the “ON” position and the bin control cal.
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 tim er times out at 30 min. the display will show “E2” and the unit stops.
7 WATER PAN CLOSES/FREEZE: When the water pan closes and the hall IC turns on the water valve opens to supply ice making wate r for a specific time. The supply time varies between startup, reset, and end of bin control cycle between partial flush and full drain.
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.
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 .
10 CONTROL BOARD: A solid state board controls the IM operation. The control board is factory adjusted to produce consistent ice in all ambient conditions.
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. Clean and sanitize the water distribution system annually using the recommended clean er.
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. 5) Remove the screw, and then move the water tank drain pipe to the drain position.
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.
14 5) Remove the front panel and top panel. 6) Move the control switch to the “WASH“ position. 7) 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. 8) Replace the front panel and top panel in their correct positions.
15 21) Replace the front panel. 22) Clean the storage bin liner using a neutral cleaner . Rinse thoroughly after cleaning. 23) T urn on the power supply to start the automatic ice making process.
