IMPORTANT
Only qualied service technicians should install, service, and maintain the
icemaker. No installation, service, or maintenance should be undertaken until
the technician has thoroughly read this Instruction Manual. Likewise, the owner/
manager should not proceed to operate the icemaker until the installer has
instructed them on its proper operation. Failure to install, operate, and maintain
the equipment in accordance with this manual may adversely affect safety,
performance, component life, and warranty coverage.
Hoshizaki provides this manual primarily to assist qualied service technicians in the
installation, maintenance, and service of the icemaker.
Should the reader have any questions or concerns which have not been satisfactorily
addressed, please call, write, or send an e-mail message to the Hoshizaki Technical

Important Safety Information
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
shock, injury, re, or damage to the unit.

See the nameplate for electrical and refrigeration specications. This nameplate is located
on the rear panel.
Since this nameplate is located on the rear panel of the icemaker, it cannot be read when
the back of the icemaker is against a wall or against another piece of kitchen equipment.
Therefore, the necessary electrical and refrigeration information is also on the rating label,
which can be easily seen by removing only the front panel of the icemaker.

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

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."

storage bin.
1) Is the icemaker level?
2) Is the icemaker in a site where the ambient temperature is within 45°F to 100°F (7°C to
38°C) and the water temperature within 45°F to 90°F (7°C to 32°C) all year around?
3)Isthereatleast6"(15cm)clearanceatsides,rear,andtopoftheicemakerforproper
air circulation and ease of maintenance and service?
4) Have the shipping carton, tape, and packing material been removed from the icemaker?
Are the cube guides in their correct positions? Are the separators between the
evaporator banks properly attached to their holding clips?
5) Are all components, fasteners, and thumbscrews securely in place?
6) Have all electrical and water connections been made? Do electrical and water
connections meet all international, national, state, and local code and regulation
requirements?

Has a proper ground been installed to the icemaker? Has the transformer's voltage tap
switch been positioned to match incoming voltage?
8) Are the water supply line shut-off valves and drain valves installed? Has the water
supply pressure been checked to ensure a minimum of 10 PSIG and a maximum of
113 PSIG?
Note: The icemaker may stop running when the water supply is off, or if the pressure
is below 10 PSIG. When the proper water pressure is reached, the icemaker
automatically starts running again.
9) Are the compressor hold-down bolts snug? Have the refrigerant lines been checked to
make sure they do not rub or touch other lines or surfaces?
10) Has the end user been given the instruction manual, and instructed on how to operate
the icemaker and the importance of the recommended periodic maintenance?

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.
