This procedure for reversing the AM-50 door is shown in the Instruction Manual provided with the unit. View this manual at www.hoshizaki.com. - 4 -...
- Page 5 (AM-50) 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, as shown in the center picture.
- Page 6 Thermistor start in an unloaded condition, greatly extending the life of the compressor. This operation is common among all Hoshizaki cube icemakers. During the initial harvest, the compressor, hot gas valve and water valve will be energized.
- Page 7 Throughout freeze cycle, which normally last 14~33 minutes, depending on model and operating conditions, the unit will continue to circulate the water from the reservoir to the horizontal evaporator, through the spray tubes. When the temperature of the evaporator has reached approximately 26.6 F (-3 C) and the thermistor signals approximately 6.8K...
- Page 8 The AM series uses 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.
- Page 9 If it is necessary to gain access to the control (AM-50BAE) box, the louvered panel must be removed. AM-50BAE: This can be done by removing the two screws from the lower portion of the front panel and pulling the panel down slightly to dis-engage the mounting tabs.
- Page 10 CONTROL BOARD: A solid state board controls the AM operation. The control board is factory adjusted to produce consistent ice in all ambient conditions. “NO SEASONAL ADJUSTMENTS ARE REQUIRED” There are no adjustments needed, however there are two variable resistors on the control board.
- Page 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.

- Page 13 Disconnect the suction tube that connects the pump motor to the sump tank. The AM-50BAE has a locking tabs that can (AM-50) 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.
- Page 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 water plate and will be removed as one assembly in the next step.
- Page 15 (AM-50) Refit the caps on the cleaning outlets to seal them off. (AM-100 & AM-150) AM-50: Slide in the spray assembly along the 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.
- Page 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-50) AM-100 & AM-150: Place the rear of the water tank on the water tank rest at the back of the storage bin.
- Page 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. (AM-50) The AM-100 & AM-150 uses a simple push on suction hose. Note: A loose fitting may cause a water leak.

- Page 24 High side process tube Note: All Hoshizaki ice machines are critically charged. Since the AM-series have small refrigeration circuits and the AM- 100 and AM-150 use cap tube systems this is especially true. The AM-series does not come from the factory with any type of refrigeration system access.
