Page 15: Installation And Operating Instructions
• Check that the compressor is snug on all mounting pads. • 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 48" wide or wider. The recommended storage bin is Hoshizaki Ice Storage Bin, Model B-800 series. 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-21F or URC-22F is recommended. B. How to Remove Panels Top Panel See Fig. -
Page 16: Location
For best operating results: • Icemaker should not be located next to ovens, grills, or other high heat producing equipment. • Location should provide a firm and level foundation for the equipment. • For KM-1601SAH/3, allow 9" (23 cm) clearance at rear, sides, and top for proper air circulation and ease of maintenance and/or service should they be required. • For KM-1601SWH/3 and KM-1601SRH/3, allow 6" (15 cm) clearance at rear, sides, and top for proper air circulation and ease of maintenance and/or service should they be required. D. Setup... - Page 17 6) Install the bin control thermostat as follows: a. Remove the baffle from the storage bin. b. Remove the tie securing the bin control thermostat assembly. Remove the 2 thumbscrews below the bin control thermostat assembly. c. Remove the bin control thermostat assembly from the shipping hook by lifting it up and shifting it to the right.

F. Electrical Connection WARNING For All Models 1. Electrical connection must be hard-wired and must meet national, state, and local electrical code requirements. Failure to meet these code requirements could result in death, electric shock, serious injury, fire, or severe damage to equipment. - Page 21 • On three phase models, the transformer’s voltage tap switch must be positioned to match incoming voltage at startup. See Fig. 8b. • CAUTION! On three phase models, connect the highest incoming voltage supply ("stinger leg") to the red power supply wire (red common wire to the compressor). • The opening for the power supply connection is 7/8" DIA to fit a 1/2" trade size conduit.

4. Line Set Mounting Holes 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.G.4.a) Factory Line Set Installation." Field fabricated line sets are allowed. For details, see "II.G.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.G.5. Refrigerant Charge (Line Set Exceeding 66 Feet)."... - Page 24 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 25 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 26: 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. -
Page 27: Stacking Condenser Unit
1) Remove the louver panel. See Fig. 15. 2) Remove the junction box cover on the remote condenser unit. Remove the fan motor junction box cover on the icemaker. 3) Install a ground wire from the icemaker to the remote condenser unit. Use wire of an appropriate gage and outdoor rating. -

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), storage bin drain line, and water-cooled condenser drain line (if applicable) must be run separately. -
