Throughout this manual, notices appear to bring your attention to situations which could
result in death, serious injury, or damage to the unit.
WARNING Indicates a hazardous situation which could result in death or
serious injury.
CAUTION Indicates a situation which could result in damage to the unit.
IMPORTANT Indicates important information about the use and care of the
unit.
WARNING
This icemaker should be destined only to the use for which it has been
expressly conceived. Any other use should be considered improper and
therefore dangerous. The manufacturer cannot be held responsible for eventual
damage caused by improper, incorrect, and unreasonable use.
To reduce the risk of death, electric shock, serious injury, or re, follow
basic precautions including the following:
•Electricalconnectionmustbehard-wiredandmustmeetinternational,
national, state, and local electrical code requirements. Failure to meet these
code requirements could result in death, electric shock, serious injury, re, or
severe damage to equipment.
•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 fuse, or damage to existing wiring. This
could lead to heat generation or re.
•THIS UNIT MUST BE GROUNDED. Failure to properly ground this unit could
result in death or serious injury.
•Thisunitshouldbedisassembledorrepairedonlybyqualiedservice
personnel to reduce the risk of electric shock, injury, or re.
•Donotmakeanyalterationstotheunit.Alterationscouldresultinelectric

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. To prevent damage
to the water supply line, drain the icemaker if the air temperature is going to
gobelow32°F(0°C).See"III.C.PreparingtheIcemakerforLongStorage."
For best operating results:
•Theicemakershouldnotbelocatednexttoovens,grills,orotherhighheatproducing
equipment.
•Thelocationshouldprovidearmandlevelfoundationfortheequipment.

maintenance and/or service should they be required.
D. Setup
CAUTION
Before operating the icemaker, the bin control thermostat assembly must be
installed correctly. Failure to properly install the assembly could result in ice
backup and unit damage.
1) Follow the storage bin setup procedure.
2) Position the storage bin in the selected permanent location.
3) Place the icemaker on top of the storage bin.
4) Secure the icemaker to the storage bin using the 2 mounting brackets and the bolts
provided. See Fig. 2.

d. Make sure the left side and bottom of the assembly are ush against the wall and
base panel.
e. Secure the assembly into place with the thumbscrews (unless you are installing a
secondunit).(See"II.E.InstallationofSecondUnit.")
f. Insert the plug into the receptacle on the assembly until it locks into place.
g. Remove the 2 screws from the lower part of the thermostat bracket (plastic) and use
them to attach the thermostat extension bracket (stainless) to the thermostat bracket
(plastic).
6) Level the icemaker and storage bin in both the left-to-right and front-to-rear directions.
Adjust the storage bin legs to make the icemaker level.
7) Make sure the icemaker and storage bin are properly secured.
8) Seal as required by sanitation code.
9) Replace the panels and baffle in their correct positions unless you are installing a
secondunit.Ifinstallingasecondunit,see"II.E.InstallationofSecondUnit."

1. Water supply and drain connections must be installed in accordance with
applicable international, 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. To prevent damage to equipment, do not operate the icemaker when the
water supply is off, or if the pressure is below 10 PSIG. Do not run the
icemaker until the proper water pressure is reached.

WARNING
1. Only qualied service technicians should attempt to service this icemaker.
2. 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.
3. The storage bin is for ice use only. Do not store anything else in the storage
bin.
A. Cleaning & Sanitizing Instructions
Hoshizaki recommends cleaning and sanitizing this unit at least once a year. More
frequent cleaning and sanitizing, however, may be required in some existing water
conditions.
WARNING
1. To prevent injury to individuals and damage to the icemaker, do not use
ammonia type cleaners.
2. Carefully follow any instructions provided with the bottles of cleaning and
sanitizing solution.
3. Always wear liquid-proof gloves and goggles to prevent the cleaning and
sanitizing solutions from coming into contact with skin or eyes.
4. To prevent damage to the water pump seal, do not operate the icemaker with
thecontrolswitchinthe"WASH"positionwhenthewatertankisempty.
IMPORTANT
1. The cleaning valve is opened during cleaning and sanitizing to allow solution
ow to the inside of the evaporator. It should be closed for all icemaking
operation. The compressor will not operate unless this valve is completely
closed.
2. To close the cleaning valve, the valve handle should be at a right angle to the
valve body. To open the cleaning valve, the valve handle should be parallel to
the valve body.
