- 2 - 20mm All AM models have similar sequence of op eration. This manual is designed as a generic AM Training manual. The Hoshizaki AM series ice machine uses a horizontal evaporator design which forms a unique cube shape.
- 3 - WATER INLET CONNECTIONS A standard 120 - volt power cord provides the electrical connection. The unit is designed to operate on a separate 15 - amp circuit. Inlet Water Line Connection • 1 st production units had a 3/4" BSP connection directly to the inlet water valve.
- 4 - In the case of an AM - 50 if a drain is not located in an area that will allow for the proper fall, there is an optional condensate pump available that can be installed directly int o the unit. After removing the louvered rear panel the pump location is defined by the two metal tabs.
- 5 - The horizontal evaporator and water distribution system are unique to the Hoshizaki AM and IM series. The AM and the IM series are similar in the fact that they both make ice on a horizontal evaporator . The AM evaporator design however is different , a s shown in the center picture.
- 6 - Th e AM series uses a combination thermistor and control board to control the sequence of oper ation. When the toggle switch is placed in the “ON” position and the bin control calls for ice, the unit will begin in the initial harvest cycle.
- 7 - Throughout the freez e cycle, which normally last 1 4 ~ 3 3 minutes, depending on model and operating conditions, the unit will continue to circulate the water from the reservoir to the horizontal evaporator, through th e spray tubes. When the temperature of the evaporator has reached approximately 2 6.
- 8 - The AM series use s a thermostatic bin control located on the right rear side of the ice storage compartment. This control will open when ice touches the sensing bulb and the unit will shut down This control includes a small heater to eliminate the control opening due to low ambient temperatures in the bin.
- 9 - AM - 50BAE: The control switch is marked “ICE - OFF - WASH” and is located on the lower right front of the unit . AM - 100 & AM - 150: The control switch is located on the control box which is located behind the front panel on the left hand side of the unit .
- 10 - CONTROL BOARD : A solid state board controls the A M operation. The control board is factory adjusted to produce consistent ice in all ambient conditions. “NO SEASONAL ADJUSTMENTS ARE REQUIRED” There are no adjustments ne eded , however there are two variable resistors on the control board.
- 11 - Preventative maintenance for the AM is simple. 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.
- 12 - Cleaning tips: • A detailed cleaning label is located on the back of the icemaker door of the AM - 50BAE or on the back of the bin baffle of the AM - 100 & AM - 150 . More detailed instructions are included in the customers Instruction Manual or in the product Service Manual.
- 13 - Disconnect the suction tube that connects the pump motor to the sump tank . The AM - 50BAE has a locking tabs that can be released by compressing both plastic tabs to unlock the joint in the direction of the black arrows and pulling the pipe clear to drain the Tank .
- 14 - AM - 50BAE: Lift off the ice chute from the front frame pipe and then from the rear frame pipe clean and sanitize the ice chute The AM - 100 & AM - 150: ice chute is incorporated into the wat er plate and will be removed as one assembly in the next step.
- 15 - Refit the caps on the cleaning outlets to seal them off. AM - 50: Slide in the spray assembly along t he rails on the right and left brackets. Refit the discharge tube securely on the spray outlet. Note: A loose fitting may cause a water leak and improper water spray during freeze.
- 16 - AM - 50: Position and lock the ice chute on to the front and rear frame pipes by pushing the chute down until it clicks AM - 100 & AM - 150: Place the rear of the water tank on the water tank rest at the back of the storage bin. Use the thumbscrews to secure the front of the water tank to the mechanism base.
- 17 - AM - 50BAE: Refit the suction tube on to the water tank inlet by pushing the joint to lock it securely in the arrow directions. The AM - 100 & AM - 150 uses a simple push on suction hose. Not e: A loose fitting may cause a water leak. Hook each separator on the rail and pull it hard toward you until it locks in place with a click.
