II. INSTALLATION AND OPERATING INSTRUCTIONS 1. CHECKS BEFORE INSTALLATION IMPORTANT 1. Remove shipping carton, tape(s) and packing. If packing material is left in the icemaker, it will not work properly. 2. Ensure all components, fasteners and thumbscrews are securely in place. 1) Remove the panels to prevent damage when installing the icemaker. (See “2. HOW TO REMOVE PANELS.”) 2) Remove the package containing the accessories from the compressor compartment.
3. LOCATION CAUTION This icemaker is not intended for outdoor use. Normal operating ambient temperature should be within +45°F to +100°F; Normal operating water temperature should be within +45°F to +90°F. Operation of the icemaker, for extended periods, outside of these normal temperature ranges may affect production capacity. For best operating results: • Icemaker should not be located next to ovens, grills or other high heat producing equipment.
IMPORTANT Before operating the icemaker, the Bin Control Thermostat must be installed correctly. 5) Install the Bin Control Thermostat as follows. See Figures 3a, b and c. (a) Remove the Tie securing the Bulb Holder. Remove the Thermostat Bracket (F) from the Shipping Hook by lifting up the Bracket (F) and shifting it to the right. (b) Lower the Thermostat Bracket through the hole located at the bottom of the icemaker.
(g) Remove the Bin Control Bracket Extension from the accessory bag. (h) Remove the Baffle from the Bin. (i) Remove the two screws holding the Bulb Holder (C) to the Thermostat Bracket (E). If a Hoshizaki Bin is being used: (j) Remove the two screws holding the Bulb Holder (C) and the Thermostat Bulb Attachment together. Put aside the Bulb Holder (C); it is not needed with the Hoshizaki Bin. (k) Use two of the screws to attach the Bin Control Bracket Extension to the Thermostat Bracket (E).
6) Level the icemaker/Storage Bin in both the left-to-right and front-to-rear directions. Adjust the Ice Bin Legs to make the icemaker level. 7) Place the panels in position. 5. INSTALLATION OF THE SECOND UNIT - See Figures 4 and 5 1) See “4. SET UP” for the lower unit installation. 2) Remove the Top Panel and the Top Insulation of the lower unit. The Top Panel and the Top Insulation of the lower unit are not required when installing the second icemaker.
9) Insert the plug of the upper unit into the receptacle of the upper unit on the Bracket until it locks in place. 10) Place the panels in position. Fig. 5a (with Hoshizaki Bin) Fig.
6. ELECTRICAL CONNECTION WARNING 1. Electrical connection must be made in accordance with the instructions on a “WARNING” tag, provided with the pig tail leads in the Junction Box. 2. This icemaker requires a ground that meets the national and local electrical code requirements. To prevent possible electrical shock to individuals or extensive damage to the equipment, install a proper ground wire to the icemaker.
7. INSTALLATION OF REMOTE CONDENSER UNIT [a] CHECKS BEFORE INSTALLATION 1) Unpack and remove shipping carton, tape(s) and packing. 2) Check that the refrigerant lines do not rub or touch lines or other surfaces, and that the fan blade turns freely. [b] LOCATION The condenser unit must be positioned in a permanent site under the following guidelines. • A firm and flat site. • A dry and well ventilated area with 24" clearance on both front and rear for ease of maintenance and service should they be required.
[c] SET UP 1) Secure the Legs to the condenser unit with eight M8 x 16 mm. Hexagon Bolts and M8 Nuts as shown in the illustration. See Fig. 8. Note: Locate the Legs symmetrically. 2) The Legs have eight mounting holes. Secure the Legs with eight bolts (not included). 3) Install enough length of two copper tubings provided with Aeroquip couplings between the icemaker and the condenser unit. The two copper tubings should be insulated separately. See Fig. 9.
[d] ELECTRICAL CONNECTION WARNING This remote condenser unit requires a ground that meets the national and local electrical code requirements. To prevent possible electrical shock to individuals or extensive damage to equipment, install a proper ground wire to this condenser unit. • This condenser unit must be connected to the Fan Motor Junction Box on the icemaker. • The opening for the power supply connection is 7/8" DIA to fit a 1/2" trade size conduit.
[e] STACKING CONDENSER UNIT 1) Secure the lower condenser unit to the Legs with eight bolts (not included). 2) Attach the upper condenser unit on the top of the lower. 3) Secure the upper condenser unit with the four screws provided. 4) Install refrigerant lines, and make electrical connection for each Fan Motor as shown in Items [c] and [d]. Fig.
8. WATER SUPPLY AND DRAIN CONNECTIONS - See Fig. 12 WARNING To prevent damage to the pump assembly, do not operate the icemaker when the water supply is OFF, or if the pressure is below 10 PSIG. Do not run the icemaker until the proper water pressure is reached. • Water supply inlet is 1/2" female pipe thread (FPT). Note: On water-cooled model, two water supply inlets are provided. One is for the icemaker, and the other is for the water-cooled condenser.

10. START UP CAUTION 1. All parts are factory-adjusted. Improper adjustments may result in failure. 2. If the unit is turned off, wait for at least 3 minutes before restarting the icemaker to prevent damage to the Compressor. 3. Do not operate the unit in the “WASH” position without water in the Water Tank. This will cause damage to the Water Pump seal. 1) Open the Water Supply Line Shut-off Valve. 2) Remove the Front Panel. 3) Move the Control Switch, on the Control Box, to the “ICE” position.
11. PREPARING THE ICEMAKER FOR LONG STORAGE IMPORTANT When shutting off the icemaker for an extended time, drain out all water from the water tank and remove the ice from the Storage Bin. The Storage Bin should be cleaned and dried. Drain the icemaker to prevent damage to the water supply line at sub-freezing temperatures, using air or carbon dioxide. Shut off the icemaker until the proper ambient temperature is resumed.
4) Close the Potable Water Supply Line Shut-off Valve and open the Potable Water Supply Line Drain Valve. See Fig. 12. 5) Allow the line to drain by gravity. 6) Attach compressed air or carbon dioxide supply to the Potable Water Line Drain Valve. 7) Move the Control Switch to the “ICE” position. 8) Blow the potable water line out using compressed air or carbon dioxide. [3] Drain the Potable Water Tank: 1) Turn off the Power Supply Switch.
III. CLEANING AND MAINTENANCE INSTRUCTIONS IMPORTANT Ensure all components, fasteners and thumbscrews are securely in place after any maintenance or cleaning is done to the equipment. 1. CLEANING INSTRUCTIONS WARNING 1. HOSHIZAKI recommends cleaning this unit at least once a year. More frequent cleaning, however, may be required in some existing water conditions. 2. To prevent injury to individuals and damage to the icemaker, do not use ammonia type cleaners. 3.
[a] CLEANING PROCEDURE 1) Dilute approximately 38 fl. oz. of recommended cleaner Hoshizaki “Scale Away” or “LIME-A-WAY,” (Economics Laboratory, Inc.) with 7 gal. of water. 2) Remove all ice from the Evaporator and the Storage Bin. Note: To remove cubes on the Evaporator, turn off the power supply and turn it on after 3 minutes. The defrost cycle starts and the cubes will be removed from the Evaporator. 3) Turn off the power supply.
20) Remove the Front Panel, and fully open the Cleaning Valve. 21) Move the Control Switch to the “WASH” position. 22) Replace the Front Panel in its correct position. 23) Turn on the power supply to rinse off the cleaning solution. 24) Turn off the power supply after 5 minutes. 25) Remove the Front Panel and the Insulation Panel. 26) Remove the Cap located on the front bottom part of the Ice Dropping Hole. Drain the Water Tank. Replace the Cap and the Insulation Panel in their correct position.
9) Close the Cleaning Valve. 10) Move the Control Switch to the “ICE” position. 11) Replace the Front Panel in its correct position. 12) Clean the Storage Bin with water. 13) Turn on the power supply, and start the automatic icemaking process. 2.
