Lift up and towards you. • Top Panel: Remove the 2 screws, and lift off. -
Page 12: Location
C. Location 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. - Page 13 5) Install the bin control thermostat as follows: a. Remove the baffle from the bin (if applicable). b. Remove the tie securing the bin control thermostat assembly. Remove the 2 thumbscrews and the "Z" bracket. See Fig. 3. c. Remove the bin control thermostat assembly from the shipping hook. Lower the thermostat extension bracket (stainless) with the thermostat bulb attachment and thermostat bulb through the hole located at the bottom of the icemaker.

Page 16: Electrical Connection
F. Electrical Connection 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 extensive damage to equipment. - Page 17 • On three phase models, the transformer's voltage tap switch must be positioned to match incoming voltage at startup. • 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. KMH-2000SWH3 KMH-2000SRH3 Fig. 7b WARNING ELECTRICAL CONNECTION THIS UNIT MUST BE GROUNDED Failure to properly ground or wire this unit could result in death, serious injury, or severe damage to the icemaker.

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. -
