II. Installation and Operating Instructions A. Checks Before Installation IMPORTANT 1. Remove all shipping cartons, tape 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. • Remove the panels to prevent damage when installing the icemaker. (See "B. How to Remove Panels.") • Remove the package containing the accessories from the compressor compartment.
C. Location WARNING This icemaker is not intended for outdoor use. Normal operating ambient temperature should be within +45°F to +100°F (+7°C to +38°C); Normal operating water temperature should be within +45°F to +90°F (+7°C to +32°C). 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.
CAUTION Before operating the icemaker, the bin control thermostat assembly must be installed correctly. Failure to properly install the assembly could result in ice backup and unit damage. 5) Install the bin control thermostat. a. Remove the baffle from the bin. b. Remove the tie securing the bin control thermostat assembly. Then, remove the thumbscrew and the "Z" bracket. c. Remove the bin control thermostat assembly from the shipping hook by lifting it up and shifting it to the right.
If a Hoshizaki B-800, B-900 or B-1150 bin is being used: g. Put aside the "Z" bracket; it is not needed with the bins listed above. h. Remove the two screws from the lower part of the thermostat bracket (plastic) and use them to attach the thermostat extension bracket (stainless) to the thermostat bracket (plastic). Thermostat Bracket (plastic) Thermostat Extension Bracket (stainless) Fig. 4 If a Hoshizaki B-1300, B-1500, B-1650 or non-Hoshizaki bin is being used: g.
7) Remove the thermostat bulb attachment (plastic) of the upper unit from the thermostat extension bracket (stainless). 8) Carefully remove the thermostat bulb from the thermostat bulb attachment (plastic) of the upper unit. 9) Carefully route the thermostat bulb and capillary tubing of the upper unit through the bottom hole of the upper unit. Remove the bushing from the lower bin control thermostat assembly. Route the bulb and tubing through the hole in the assembly and down into the bin.
F. 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.
G. Installation of Remote Condenser Unit 1. 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. 2. 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.
3. Setup 1) Secure the legs to the condenser unit with eight M8×16 mm hexagon bolts and M8 nuts as shown in the illustration. See Fig. 10. 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 Parker quick connect couplings between the icemaker and the condenser unit. The two copper tubings should be insulated separately. See Fig. 11.
4. 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.
H. Water Supply and Drain Connections See Fig. 14a, 14b and 14c 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.

J. Startup 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.
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. A. 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.
1. 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.
24) Turn on the power supply to rinse off the cleaning solution. 25) Turn off the power supply after 5 minutes. 26) Remove the front panel and the insulation panel. 27) 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 positions. Note: Do not replace the insulation panel when you proceed to "2. Sanitizing Procedure." 28) Repeat the above steps 16 through 27 three more times to rinse thoroughly.
2. Storage Bin and Scoop • Wash your hands before removing ice. Use the plastic scoop provided (bin accessory). • The storage bin is for ice use only. Do not store anything else in the bin. • Keep the scoop clean. Clean it by using a neutral cleaner and rinse thoroughly. • Clean the bin liner by using a neutral cleaner. Rinse thoroughly after cleaning. 3. Air Filter A plastic mesh air filter removes dirt or dust from the air, and keeps the condenser from getting clogged.
2. Remove the water from the potable water supply line: 1) Remove the front panel. (Except water-cooled model) 2) Move the control switch on the control box to the "OFF" position. 3) Wait 3 minutes. 4) Close the potable water supply line shut-off valve and open the potable water supply line drain valve. See Fig. 14a, 14b, or 14c. 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.
