Page 9: Installation And Operating Instructions
• See the nameplate on the rear panel, and check that your voltage supplied corresponds with the voltage specified on the nameplate. • This icemaker can be installed on a storage bin 30" wide or wider. Hoshizaki Ice Storage Bin, Model B-500 series is recommended. For further options, contact your local Hoshizaki distributor. • On remote air-cooled model, a remote condenser unit is needed. Hoshizaki Remote Condenser Unit, Model URC-9F is recommended. B. How to Remove Panels See Fig. 1... -

C. Location CAUTION 1. 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 icemaker performance. -

6. To reduce the risk of electric shock, make all remote condenser unit connections before connecting the icemaker power supply. 7. On remote air-cooled models, the icemaker should have power for a minimum of 4 hours prior to startup to prevent compressor damage. • Usually an electrical permit and services of a licensed electrician are required. • The maximum allowable voltage variation is ±10 percent of the nameplate rating. • The opening for the power supply connection is 7/8" DIA to fit a 1/2" trade size conduit.

4. Line Set CAUTION The icemaker, line set, and remote condenser unit must contain the same type of refrigerant. Mixing of refrigerants will result in improper operation and possible damage to the refrigeration system. • Precharged factory line sets, available as optional equipment from Hoshizaki America, are recommended. For details, see "II.F.4.a) Factory Line Set Installation." Field fabricated line sets are allowed. For details, see "II.F.4.b) Field Fabricated Line Set Installation." • The maximum line length for the standard refrigerant charge is 66 feet. With additional refrigerant, the maximum line length is 100 feet. For details, see "II.F.5. Refrigerant Charge (Line Set Exceeding 66 Feet)."... -

2) Insulate the two copper tubes separately. 3) Install Parker quick connect couplings on each end. OS-QUICK , a universal quick connect coupling kit available as optional equipment from Hoshizaki America, is recommended. CAUTION! Before brazing, remove the Schrader valve core from the access port. - Page 15 6) Evacuate through the Schrader access ports on the Parker quick connect couplings and charge with R-404A refrigerant vapor to a pressure of 15 to 30 PSIG. 7) Connect the refrigerant lines to the appropriate male fittings on the remote condenser unit first and then at the icemaker.

Page 16: Refrigerant Charge (Line Set Exceeding 66 Feet)
The maximum line length for the standard refrigerant charge is 66 feet. Should an installation require a longer line length, additional refrigerant must be added. Add 0.4 oz. of R-404A for each foot over 66 feet to a maximum of 100 feet. Hoshizaki Technical Support is available at 1-800-233-1940 for recommendations. -

10 PSIG. Do not run the icemaker until the proper water pressure is reached. • A plumbing permit and services of a licensed plumber may be required in some areas. • External filters, strainers, or softeners may be required depending on water quality. Contact your local Hoshizaki distributor for recommendations. • Water supply pressure should be a minimum of 10 PSIG and a maximum of 113 PSIG. If the pressure exceeds 113 PSIG, the use of a pressure reducing valve is required. • The icemaker and condensation drain line(s) and storage bin drain line must be run separately. - Page 19 Drain Outlet 3/8" OD Tube Bin Drain Outlet 3/4" FPT Separate piping to approved drain.

Page 20: Final Checklist
H. Final Checklist WARNING CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are securely in place after installation. Make sure that none have fallen into the storage bin. 1) Is the icemaker level? 2) Is the icemaker in a site where the ambient temperature is within 45°F to 100°F (7°C to 38°C) and the water temperature within 45°F to 90°F (7°C to 32°C) all year around? 3) Is there at least 6" (15 cm) clearance at sides, rear, and top of the icemaker for proper air circulation and ease of maintenance and service? -
Page 21: Startup
I. Startup WARNING 1. All parts are factory-adjusted. Improper adjustments may adversely affect safety, performance, component life, and warranty coverage. 2. If the icemaker is turned off, wait for at least 3 minutes before restarting the icemaker to prevent damage to the compressor. 3. -
