Resumen del manual
The Hoshizaki AM series ice machine uses a horizontal evaporator design which forms a unique cube shape. 20mm 25mm The compact AM-50BAE unit is 14 7/8”w x 22 5/8”d x 33 1/2”h and is designed for counter-top, under-counter, or freestanding installations with up to 51 pounds of production and 30 pounds of storage The AM-100 and AM-150 are for under counter or free standing applications. The AM-100 dimensions are 24 15/16”w x 20 1/2”d x 39”h with 6” legs and can produce up to 105 and pounds with 44 pounds of storage. The AM150 measures 27 11/16”w x 27 15/16”d x 39”h with 6” legs and production up to 150 pounds with 88 pounds of storage. -2 WATER INLET CONNECTIONS 4A3207-01 3/8” Male flare 4A3240-01 1/2” FPT DRAIN CONNECTIONS (AM-50 through April 2004) 5/8” I.D. rubber hose AM-50 from May 2004 1/2” FPT (AM-100 & AM-150) 3/4” MPT 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 1st • production units had a 3/4" BSP connection directly to the inlet water valve. (DO not connect with 3/4" FIP) • Fitting (4A3207-01) and gasket 413854-01 were used from May through July production. (Through August on the AM-100BAE and AM150 BAF) • Fitting (4A3240-01) and gasket 413854-01 were added in August 03 on the AM-50BAE and September 03 on the AM-100BAE and AM150BAF. If no fitting is included, order either fitting /gasket above or use 3/4" hose type fitting to make this connection. A minimum 3/8” water line is required for proper operation. Drain line connection The drain connection for the AM-50 was 5/8” I.D. hose until April of 2004 and was located on the left rear of the unit. A standard 3/4” male insert fitting can be used to connect this drain. From May 2004 the drain fitting is 1/2” FPT. A minimum 1/2” I.D. vented drain is required when making this connection. The drain for the AM-100 and AM-150 is a 3/4” MPT. Since the unit will likely be enclosed, it is recommended to use flexible, supply and drain connections. This will allow easy removal if service is necessary. -3 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 into the unit. After removing the louvered rear panel the pump location is defined by the two metal tabs. This pump has a built in safety that will shut the AM-50 down in the event of a pump problem. This pump is available as an accessory through your local distributor. Simply follow the instructions included with the pump for details on the installation. The AM-50 door can be field converted from the standard right hinged door to a left hinged door without the use of any additional hinge kits. The AM-100 and AM-150 use a spring loaded drop down door design therefore can not be reversed. This procedure for reversing the AM-50 door is shown in the Instruction Manual provided with the unit. View this manual at -4 (AM-50) 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, as shown in the center picture. The moving IM water plate and associated parts are eliminated with this simple design. The AM-50BAE produces 24 cubes and .60 pounds per cycle. The AM-100BAE and AM-150BAF produce 60 cubes and 1.54 pounds per cycle. The AM series sequence of operation is also different. The sequence of operation for the AM series will be explained in the following pages. (AM-100 & AM-150) -5 The AM series uses a combination THERMISTOR thermistor and control board to control the sequence of operation. 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. Starting the unit in harvest allows the compressor to 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. The initial harvest is a timed harvest. After 50 seconds, the control board will energize the X1 board relay to start the pump motor and condenser fan motor, switching the unit into the freeze cycle. After the initial harvest, the X2 board relay will remain energized during the freeze cycle. This allows the water valve to feed fresh water for an additional 50 seconds. This extended fill, only takes place when the unit has restarted from a power interruption or when the bin control calls for ice. During the normal harvest cycle the water valve will de-energize at the beginning of freeze or in the event of long harvest the valve will have a maximum open time of 102 seconds. This could occur in the event of operation in low water and ambient temperatures. During normal operat...
