Remove thumbscrew, lift up slightly, and pull toward you. Fig. 1 3. LOCATION WARNING This icemaker is not intended for outdoor use.
4. SET UP 1) If mounting unit on top of a storage bin, unpack the storage bin, and attach the four adjustable legs provided (bin accessory) to the bottom of the storage bin. If mounting unit on top of a dispenser, follow the dispenser set-up procedure. 2) Position the Storage Bin/Dispenser Unit in the selected permanent position. 3) Place the icemaker on the top of the Storage Bin/Dispenser Unit.
5. 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. • The white lead must be connected to the neutral conductor of the power source.
6. 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 moves 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. 5. 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. 6.
[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.
7. WATER SUPPLY AND DRAIN CONNECTIONS - with Storage Bin See Fig. 9 - with Dispenser Unit See Fig. 10 IMPORTANT To prevent damage to the pump assembly, do not operate the icemaker when the water supply is OFF, or if the pressure is below 14.5 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 models, two water supply inlets are provided.

9. START UP IMPORTANT 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.

10. PREPARING THE ICEMAKER FOR LONG STORAGE IMPORTANT When shutting off the icemaker for an extended time, drain out all water from the water line 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 a foot or hand pump. Shut off the icemaker until the proper ambient temperature is resumed.
[2] Remove the water from the potable water supply line: 1) Remove the Front Panel. (Except water-cooled models) 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. 9. 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.
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 13.5 fl. oz. of recommended cleaner Hoshizaki “Scale Away” or “LIME-A-WAY,” (Economics Laboratory, Inc.) with 2.5 gallons 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 back on after 3 minutes. The defrost cycle starts and the cubes will be removed from the Evaporator. 3) Turn off the power supply. 4) Remove the Front Panel.
16) Move the Control Switch to the “ICE” position. 17) Close the Cleaning Valve. 18) Replace the Front Panel in its correct position. 19) Turn on the power supply to fill the Water Tank with water. 20) Turn off the power supply after 3 minutes. 21) Remove the Front Panel, and fully open the Cleaning Valve. 22) Move the Control Switch to the “WASH” position. 23) Replace the Front Panel in its correct position. 24) Turn on the power supply to rinse off the cleaning solution.
[b] SANITIZING PROCEDURE - Following Cleaning Procedure 1) Dilute a 5.25% Sodium Hypochlorite solution with water (Add approximately 1.25 fl. oz. to 2.5 gal. of water). 2) Remove the Insulation Panel by removing thumbscrew, lifting up the panel slightly and pulling it toward you. 3) Pour the sanitizing solution into the Water Tank. 4) Replace the Insulation Panel and the Front Panel in their correct positions. Note: Make sure that the Control Switch is in the “WASH” position and the Cleaning Valve is open.
2. MAINTENANCE IMPORTANT This icemaker must be maintained individually, referring to the instruction manual and labels provided with the icemaker. 1) Stainless Steel Exterior To prevent corrosion, wipe the exterior occasionally with a clean, soft cloth. Use a damp cloth containing a neutral cleaner to wipe off oil or dirt build up. 2) Storage Bin and Scoop • Wash your hands before removing ice. Use the Plastic Scoop provided (Bin Accessory). • The Storage Bin/Dispenser Unit is for ice use only.
