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 injury or
damage resulting from improper, incorrect, and unreasonable use.
To reduce the risk of death, electric shock, serious injury, or re, follow
basic precautions including the following:
•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 APPLIANCE MUST BE GROUNDED: This unit is equipped with a
3-prong grounding plug to reduce the risk of potential shock hazards. It must
be plugged into a properly grounded, independent 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.
•Makesurethecontrolswitchisinthe"OFF"positionbeforeplugginginor
unplugging the unit to reduce the risk of electric shock.
•Donotuseaunit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 unit, be sure to pull the
plug, not the cord, and do not jerk the cord.
•Toreducetheriskofelectricshock,donottouchtheplug,controlswitch,or
service switch with damp hands.
•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.

A. Nameplate Rating
1. DKM-500BAH
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:
•Icemakershouldnotbelocatednexttoovens,grills,orotherhighheatproducing

E. Electrical Connection
WARNING
1. Electrical connection 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 severe damage to equipment.
2. 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.
3. THIS APPLIANCE MUST BE GROUNDED: This unit is equipped with a
3-prong grounding plug to reduce the risk of potential shock hazards. It must
be plugged into a properly grounded, independent 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.
4. Do not use an extension cord.
5.Makesurethecontrolswitchisinthe"OFF"positionbeforeplugginginor
unplugging the unit to reduce the risk of electric shock.
6. Do not use a unit 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 unit, be sure to pull the
plug, not the cord, and do not jerk the cord.
7. To reduce the risk of electric shock, do not touch the plug, control switch, or
service switch with damp hands.
8. The GREEN ground wire in the factory-installed power cord is connected to
a screw on the interior panel where the cord enters the unit. If it becomes
necessary to remove or replace the power cord, be sure to connect the
power cord's ground wire to this screw upon reattachment.

F. Water Supply and Drain Connections
See Fig. 3, 4, or 5.
WARNING
1. Water supply and drain connections must be installed in accordance with
applicable national, state, and local regulations.
2. Normal operating water temperature should be within 45°F to 95°F (7°C
to 35°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.
