Important Safety Information
Throughout this manual, notices appear to bring your attention to situations which could
result in death, serious injury, damage to the appliance, or damage to property.
WARNING Indicates a hazardous situation which could result in death or
serious injury.
NOTICE Indicates a situation which could result in damage to the
appliance or property.
IMPORTANT Indicates important information about the installation, use, and
care of the appliance.
WARNING
The appliance 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 injury or damage resulting
from improper, incorrect, and unreasonable use. Failure to install, operate, and
maintain the appliance in accordance with this manual will adversely affect safety,
performance, component life, and warranty coverage and may result in costly water
damage.
To reduce the risk of death, electric shock, serious injury, or re, follow basic
precautions including the following:
• Only qualied service technicians should install and service the appliance.
• The appliance must be installed in accordance with applicable national, state, and
local codes and regulations.
• 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, re, or damage.
• The icemaker requires an independent power supply of proper capacity. See the
nameplate for electrical specications. Failure to use an independent power supply
of proper capacity can result in a tripped breaker, blown fuse, damage to existing
wiring, or component failure. This could lead to heat generation or re.
• THE ICEMAKER MUST BE GROUNDED. Failure to properly ground the icemaker
could result in death or serious injury.
• To reduce the risk of electric shock, do not touch the power switch or control switch
with damp hands.
• Move the power switch to the "OFF" position and turn off the power supply before
servicing. Lockout/Tagout to prevent the power supply from being turned back on
inadvertently.
• Do not place ngers or any other objects into the ice discharge opening.
• Do not make any alterations to the appliance. Alterations could result in electric
shock, injury, re, or damage.
4
WARNING, continued
• The appliance is not intended for use by persons (including children) with reduced
physical, sensory, or mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction concerning use of the
appliance by a person responsible for their safety.
• Children should be properly supervised around the appliance.
• Do not climb, stand, or hang on the appliance or allow children or animals to do so.
Serious injury could occur or the appliance could be damaged.
• Do not use combustible spray or place volatile or ammable substances near the
appliance. They might catch re.
• Keep the area around the appliance clean. Dirt, dust, or insects in the appliance
could cause harm to individuals or damage to the appliance.
Additional Warning for Remote Models
• THE REMOTE CONDENSER UNIT MUST BE GROUNDED. The power supply and
ground connection to the remote condenser unit are supplied from the icemaker.
Failure to properly ground the remote condenser unit could result in death or
serious injury.
• Wire routing (conduit) and disconnect (if required) must meet national, state, and
local electrical code requirements. Failure to meet these code requirements could
result in death, electric shock, serious injury, re, or damage.
NOTICE
• Follow the water supply, drain connection, and maintenance instructions carefully to
reduce the risk of costly water damage.
• In areas where water damage is a concern, install in a contained area with a oor
drain.
• Install the icemaker in a location that stays above freezing. Normal operating
ambient temperature must be within 45°F to 100°F (7°C to 38°C).
• Do not leave the icemaker on during extended periods of non-use, extended
absences, or in sub-freezing temperatures. To properly prepare the icemaker for
these occasions, follow the instructions in "IV. Preparing the Icemaker for Periods of
Non-Use."
• Do not place objects on top of the appliance.
• The dispenser unit/ice storage bin is for ice use only. Do not store anything else in
the dispenser unit/ice storage bin.

II. Installation and Operating Instructions
WARNING
• The appliance must be installed in accordance with applicable national, state, and
local codes and regulations.
• Failure to install, operate, and maintain the appliance in accordance with this
manual will adversely affect safety, performance, component life, and warranty
coverage and may result in costly water damage.
• CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews
are securely in place after installation. Make sure that none have fallen into the
dispenser unit/ice storage bin.
A. Location
NOTICE
• The icemaker is not intended for outdoor use. Normal operating ambient
temperature must be within 45°F to 100°F (7°C to 38°C); Normal operating
water temperature must 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.
• The 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 "IV. Preparing the Icemaker for Periods of Non-Use."
• The icemaker should not be located next to ovens, grills, or other high heat producing
equipment.
• Allow 6" (15 cm) clearance at rear and sides for proper air circulation and ease of
maintenance and/or service should they be required. Allow 24" (61 cm) clearance at top
to allow for removal of the auger.
• The location should provide a rm and level foundation for the appliance.
B. Checks Before Installation
• Visually inspect the exterior of the shipping container and immediately report any
damage to the carrier. Upon opening the container, any concealed damage should also
be immediately reported to the carrier.
• Remove the shipping carton, tape, and packing material. If any are left in the appliance,
it will not work properly.
• See the nameplate on the rear panel, and check that your voltage supplied corresponds
with the voltage specied on the nameplate.
• Remove the panels to prevent damage when installing the appliance. See "II.C. How to
Remove Panels."
• Remove the package containing the accessories.
13
• Remove the protective plastic lm from the panels. If the appliance is exposed to the
sun or to heat, remove the lm after the appliance cools.
• Check that the refrigerant lines do not rub or touch lines or other surfaces, and that the
fan blade (if applicable) turns freely.
• Check that the compressor is snug on all mounting pads.
• Flaker models can be installed on an ice storage bin only. Cubelet models can be
installed on either a dispenser unit or an ice storage bin. The ice storage bins listed
below are recommended.

For further options, contact your local Hoshizaki distributor.
• NOTICE! Remote models must be connected to an appropriate remote condenser
unit. The remote condenser units listed below are recommended. Connection to a
different remote condenser unit will void the warranty unless Hoshizaki approves
a different remote condenser unit for your specic application. For further
details, contact your local Hoshizaki distributor.

• On low-side models, an R-404A parallel rack system is needed. See "II.H. Connection
to an R-404A Parallel Rack System" for refrigeration circuit details.
C. How to Remove Panels
See Fig. 1
• Front Panel: Remove the screw. Lift up and
towards you.
• Top Panel: Lift up at front slightly, push rearward
and lift off.
• Side Panels: Remove the screw. Slide forward
slightly and lift off.
