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. 2. This icemaker will not work at sub-freezing temperatures.
E. Electrical Connection WARNING 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. 2. This unit requires an independent power supply. See the nameplate for proper voltage and breaker/fuse size. Failure to use a proper breaker or fuse can result in a tripped breaker, blown fuses, or damage to existing wiring.
F. Water Supply and Drain Connections See Fig. 4, 5, or 6 WARNING 1. Water supply and drain connections must be installed in accordance with applicable national, state, and local regulations. 2. 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 this normal temperature range may affect icemaker performance. 3.

A minimum of 3/8" OD copper tubing is recommended for the icemaker water supply line. • An icemaker water supply line shut-off valve and drain valve should be installed. • Storage bin and drip tray drain outlets are 3/4" FPT. A minimum of 3/4" OD hard pipe is recommended for the storage bin and drip tray drain lines.
2. Water-Cooled Condenser a) Connection to an Open Drain System • Condenser water supply inlet is 1/2" female pipe thread (FPT). A minimum of 3/8" OD copper tubing is recommended for the condenser water supply line. • A condenser water supply line shut-off valve and drain valve should be installed. • Condenser drain outlet is 3/8" FPT. A minimum of 3/8" OD hard pipe is recommended for the condenser drain line. • In some areas, a back flow preventer may be required in the condenser water supply line.
b) Connection to a Closed Loop System • Condenser water supply inlet is 1/2" female pipe thread (FPT). A minimum of 3/8" OD copper tubing is recommended for the condenser water supply line. • Condenser return outlet is 3/8" FPT. A minimum of 3/8" OD hard pipe is recommended for the condenser return line. • Shut-off valves and drain valves should be installed at both the condenser water supply inlet and condenser return outlet. • The water supply to the condenser should not drop below 4 GPM.
G. 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.
H. 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. At startup, confirm that all internal and external connections are free of leaks. 1) Open the water supply line shut-off valve(s). 2) Remove the front panel.
9) Disengage the safety switch. Move the control switch to the "OFF" position, then move the power switch to the "OFF" position. Turn off the power supply. 10) Clean the storage bin liner and the storage bin cover using a neutral cleaner. Rinse thoroughly after cleaning. Replace the storage bin cover in its correct position. WARNING! CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are securely in place. Make sure that none have fallen into the storage bin.
III. Cleaning and Maintenance WARNING CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are securely in place after any cleaning or maintenance is done to the unit. Make sure that none have fallen into the storage bin. A. Cleaning and Sanitizing Instructions Hoshizaki recommends cleaning and sanitizing this unit at least twice a year. More frequent cleaning and sanitizing, however, may be required in some existing water conditions. WARNING 1.
1. Water System a) Cleaning Solution Dilute 9.6 fl. oz. (0.29 l) of Hoshizaki "Scale Away" with 1.6 gal. (6.0 l) of warm water. b) Cleaning Procedure 1) Close the icemaker water supply line shut-off valve. 2) Move the control switch to the "DRAIN" position and allow the water system to drain for 5 minutes. Note: If the unit is running, the drain valve will not open until 2.5 minutes after the control switch is moved to the "DRAIN" position. This allows the components to cycle down.
13) After the gear motor starts, move the control switch to the "DRAIN" position and allow the water system to drain for 5 minutes. Note: If you do not sanitize the unit, move the control switch to the "ICE" position after the water system drains. Allow the icemaker to run for 30 minutes, then move the control switch to the "OFF" position. Turn off the power supply, then remove the front panel and storage bin cover. Go to step 12 in "III.A.2.
c) Cleaning and Sanitizing Procedure 1) Move the control switch to the "OFF" position, then turn off the power supply. 2) Remove the front and top panels, then move the power switch to the "OFF" position. 3) Remove the storage bin cover. 4) Remove the motor bracket thumbscrews, first from the vertical plane and then from the horizontal plane. While holding on to the corresponding agitator or auger, move the agitating motor or the dispensing motor towards you.
B. Maintenance This icemaker must be maintained individually, referring to the instruction manual and labels provided with the icemaker. The schedule below is a guideline. More frequent maintenance, however, may be required depending on water quality, the icemaker's environment, and local sanitation regulations. Consult with your local distributor about inspection and maintenance service. To obtain the name and phone number of your local distributor, visit www.hoshizaki.
C. Preparing the Icemaker for Long Storage CAUTION When storing the icemaker for an extended time or in sub-freezing temperatures, follow the instructions below to prevent damage. When the icemaker is not used for two or three days under normal conditions, it is sufficient to only move the control switch to the "OFF" position. When storing the icemaker for extended time or in sub-freezing temperatures, follow the instructions below. 1.
4) Attach a compressed air or carbon dioxide supply to the condenser water supply line drain valve. 5) Open the water regulating valve by using a screwdriver to pry up on the spring retainer underneath the spring. While holding the valve open, blow out the condenser using the compressed air or carbon dioxide supply until water stops coming out. 6) Close the drain valve(s). 7) Replace the panels in their correct positions.
