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
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 injury or damage resulting from improper,
incorrect, and unreasonable use. Failure to install, operate, and maintain the icemaker
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 qualied service technicians should install and service this icemaker.
• This icemaker must be installed in accordance with applicable national, state, and local
codes and regulations.
• This icemaker requires an independent power supply of proper capacity. See the
nameplate for electrical specications. 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.
• THIS ICEMAKER MUST BE GROUNDED: This icemaker is equipped with a
NEMA5-15 three-prong grounding plug to reduce the risk of potential shock
hazards. It must be plugged into a properly grounded, independent 3-prong wall outlet.
If the outlet is a 2-prong outlet, it is your personal responsibility to have a qualied
electrician replace it with a properly grounded, independent 3-prong wall outlet. Do not
remove the ground prong from the power cord and do not use an adapter plug.
• Do not use an extension cord.
• To reduce the risk of electric shock, make sure the control switch is in the "OFF"
position before plugging in or unplugging the icemaker.
• To reduce the risk of electric shock, do not touch the control switch or plug with damp
hands.
• Do not use an icemaker with a damaged power cord. The power cord should not be
altered, jerked, bundled, weighed down, pinched, or tangled. Such actions could result
in electric shock or re. To unplug the icemaker, be sure to pull the plug, not the cord,
and do not jerk the cord.
• Do not make any alterations to the icemaker. Alterations could result in electric shock,
injury, re, or damage to the icemaker.

WARNING, continued
• This 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 this appliance.
• Do not climb, stand, or hang on the icemaker or icemaker door or allow children or
animals to do so. Serious injury could occur or the icemaker could be damaged.
• Be careful not to pinch ngers when opening and closing the door. Be careful when
opening and closing the door when children are in the area.
• Do not use combustible spray or place volatile or ammable substances near the
icemaker. They might catch re.
• Keep the area around the icemaker clean. Dirt, dust, or insects in the icemaker could
cause harm to individuals or damage to the icemaker.
NOTICE
• Protect the oor when moving the icemaker to prevent damage to the oor.
• 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).
• If using the optional drain pump (HS-5061), test its operation every time the icemaker
is cleaned and sanitized. See "IV.E. Optional Drain Pump HS-5061" for details. If
the optional drain pump is not operating properly, water could back up and overow,
leading to costly water damage.
• To help ensure that the storage bin drain remains clear, follow the instructions in "IV.C.
Storage Bin Drain" once every 3 months or as often as necessary for conditions. If
the storage bin drain becomes clogged, water could build up in the bin and overow,
leading to costly water damage.
• If water collects in the bin and will not drain, turn off the icemaker and close the water
supply line shut-off valve. Call for service.
• 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 "V. Preparing the Icemaker for Periods of Non-Use."
• Keep ventilation openings, in the appliance enclosure or in the built-in structure, clear
of obstruction.
• Do not place objects on top of the icemaker.
• The storage bin is for ice use only. Do not store anything else in the storage bin.

3) Screw the 6 threaded wood inserts into the 1/4" holes drilled in the previous step. Make
sure that the inserts are threaded straight and that the tops of the inserts are ush to
the overlay panel surface. Otherwise, the overlay panel cannot be properly fastened to
the door.
4) Mount the door handle hardware. Hoshizaki recommends that the door handle hardware
be mounted on the edge opposite of the door hinge side (optional hinge reversal is
covered in step 6). Countersunk screw heads are required to ensure that the hardware
fasteners do not interfere with the overlay panel tting ush with the door.
5) While maintaining a hold on the door, remove the hinge stop pin from hinge (B). Pull out
the bottom of the door slightly and gently remove the door from hinge (A). See Fig. 10.
If you are leaving the door right-hinged, skip to step 7. If you would like to reverse the
door swing, proceed to step 6.
(3) Fabrication of Overlay Panel
Fabricate the overlay panel as outlined in the applicable specication on the previous
pages and the instructions below.
1) Rout a channel at the bottom of the overlay panel to the proper dimensions. See "(C)
Routed Area" in the specication diagram and Fig. 8.
2) Drill six 1/4" diameter (hardwood may require slightly larger diameter) holes 3/8"
(10 mm) deep in the locations designated. NOTICE! Use care when drilling holes for
mounting hardware. All drilled holes must be straight and drilled to the correct
diameter and depth. See "(A) Threaded Inserts" and "(B) Threaded Inserts" in the
