(if applicable) turns freely. • 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 30" wide or wider. The recommended storage bin is Hoshizaki Ice Storage Bin, Model B-500 series. For further options, contact your local Hoshizaki distributor. • 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. -

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) Install the bin control thermostat assembly as follows. See Fig. 3. a. Remove the shipping tape securing the thermostat bulb holder. Remove the thermostat bulb holder from the shipping hook by lifting it up and shifting to the right. b. - Page 11 • Usually an electrical permit and services of a licensed electrician are required. • The maximum allowable voltage variation is ±10 percent of the nameplate rating. • On single phase models, the white lead must be connected to the neutral conductor of the power source. CAUTION! Miswiring may result in severe damage to the icemaker. See Fig. 4a. • On three phase models, the transformer’s voltage tap switch must be positioned to match incoming voltage at startup. See Fig. 4b. • 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.
