II. Installation and Operating Instructions 1. Checks Before Installation WARNING Remove shipping carton, tape(s) and packing. If packing material is left in the icemaker, it will not work properly. IMPORTANT Ensure all components, fasteners and thumbscrews are securely in place. 1) Remove all panels to prevent damage when installing the icemaker. (See “2. How to Remove Panels.”) 2) Remove the package containing the accessories from inside the icemaker.
3. Location WARNING This icemaker is not intended for outdoor use. Normal operating ambient temperature should be within +45°F to +100°F; Normal operating water temperature should be within +45°F to +90°F. Operation of the icemaker for extended periods outside of these normal temperature ranges may affect production capacity. For best operating results: • Icemaker should not be located next to ovens, grills or other high heat producing equipment.
5. Electrical Connection This icemaker must have an independent power supply or receptacle of proper capacity. See the nameplate. 6. Installation of Remote Condensing Unit [a] Checks Before Installation 1) Unpack and remove shipping carton, tape(s) and packing. 2) Check that the refrigerant lines do not rub or touch lines or other surfaces, and that the fan blade turns freely. 3) Make sure that the icemaker, line sets and remote condensing unit all use R-404A refrigerant.
[c] Setup 1) Secure the legs to the condensing unit with eight M8 x 16 mm hexagon bolts and M8 nuts as shown in the illustration. See Fig. 4. Note: Locate the legs symmetrically. 2) The legs have eight mounting holes. Secure the legs with eight bolts (not included). 3) Install line sets. Precharged tubing kits, available as optional equipment from HOSHIZAKI AMERICA, are recommended. To fabricate line sets: a. Install enough length of two copper tubings between the icemaker and the condensing unit. See Fig.
5) Remove the plastic caps protecting the couplings. Apply two drops of POE oil to the male threads of the couplings. Attach the two refrigerant lines to the male couplings on the icemaker and the remote condensing unit. The couplings must be tightened 1/4 turn beyond fully seated.
7. Water Supply and Drain Connections See Fig. 7 • External filters or strainers may be required depending on the water quality. • Water supply inlet is 1/2" female pipe thread (FPT). • A water supply line shut-off valve and drain valve should be installed. A minimum of 3/8" OD copper tubing is recommended for the water supply lines. • 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.
8. Timer Setting See Fig. 8 The ice machine is equipped with an adjustable timer in the control box. It controls the amount of time the machine waits before shutting down after ice is detected by the bin control; the timer thereby controls the ice level in the bin or dispenser. The timer is factory set to the minimum delay of 10 seconds. Observe the following guidelines when selecting a timer setting. • When installed on a Hoshizaki bin, any timer setting is acceptable.

10. Startup IMPORTANT 1. The condensing unit is shipped with the contacts of the secondary low pressure switch open. Once power is supplied to the condensing unit, wait at least 4 hours before starting the unit. This will allow the system to settle and refrigerant to evaporate from oil in the compressor. To start the unit, press the manual reset button on the secondary low pressure switch. Doing this will prevent damage to the compressor. 2.
11. Preparing the Icemaker for Long Storage See Fig. 9 WARNING When shutting off the icemaker for an extended time, drain out all water from the water line and remove the ice from the storage bin. The storage bin should be cleaned and dried. Drain the icemaker to prevent damage to the water supply line at sub-freezing temperatures, using air or carbon dioxide. Shut off the icemaker until the proper ambient temperature is resumed. 1) Run the icemaker with the water supply line shut-off valve closed.
III. Cleaning and Maintenance IMPORTANT Ensure all components, fasteners and thumbscrews are securely in place after any maintenance or cleaning is done to the equipment. 1. Cleaning and Sanitizing Instructions WARNING 1. HOSHIZAKI recommends cleaning this unit at least once a year. More frequent cleaning, however, may be required in some existing water conditions. 2. To prevent injury to individuals and damage to the icemaker, do not use ammonia type cleaners. 3.
[b] Cleaning Procedure The cleaning process will remove lime deposits from the water system. 1) Remove the front panel and top panel, then turn off the power supply. 2) Close the water supply line shut-off valve. 3) Remove all ice from the storage bin. 4) Move the flush switch to the “FLUSH” position. 5) Turn on the power supply and drain out all water from the water line. 6) Turn off the power supply. 7) Remove the control water valve by removing the fitting nut and two mounting screws.
18) After the solution is drained, move the flush switch to the “ICE” position. 19) Replace the front panel in its correct position. 20) Open the water supply line shut-off valve and supply water to the reservoir. 21) When the gear motor starts, remove the front panel and turn off the power supply. 22) Drain out all water from the water line. See 4) through 6). [c] Sanitizing Solution Dilute 2.5 fl. oz. (74 ml or 5 tbs) of IMS-II Sanitizer or a 5.
11) Disassemble the bin control assembly by removing the two snap pins, shaft and actuator. 12) Soak the removed parts in .25 gallons (1 l) of sanitizing solution for 10 minutes then wipe them down. 13) Rinse the parts thoroughly. IMPORTANT If the solution is left on these parts, they will rust. 14) Replace all parts in their correct positions.
11) Remove the front panel. 12) Move the flush switch to the “FLUSH” position to drain the remainder of the solution. 13) After the solution is drained, move the flush switch to the “ICE” position. 14) Replace the front panel in its correct position. 15) Open the water supply line shut-off valve and supply water to the reservoir. 16) When the gear motor starts, remove the front panel and turn off the power supply. 17) Drain out all water from the water line. See 2) and 3).
2. Maintenance Instructions IMPORTANT 1. This icemaker must be maintained individually, referring to the instruction manual and labels provided with the icemaker. 2. To achieve optimum icemaker performance, the following parts need periodic inspection and maintenance: Extruding Head and Upper Bearing Housing and Lower Bearing Evaporator Cylinder Auger Gear Motor Mechanical Seal These parts should be inspected at least once a year or every 10,000 hours of operation.
