for maximum performance and trouble-free operation
of your equipment.
• Visit our website www.manitowocice.com for manual
updates, translations, or contact information for
service agents in your area.
• This equipment uses high voltage electricity and
contains refrigerant charge. Installation and repairs are
to be performed by properly trained technicians aware
of the dangers of dealing with high voltage electricity
and refrigerant under pressure. The technician
must also be certified in proper refrigerant handling
and servicing procedures. All lockout and tag out
procedures must be followed when working on this

attention to the safety notices in this handbook.
Disregarding the notices may lead to serious injury
and/or damage to the equipment.

DEFINITIONS
DANGER
Indicates a hazardous situation that, if not avoided,
will result in death or serious injury. This applies to the
most extreme situations.
nWarning
Indicates a hazardous situation that, if not avoided,
could result in death or serious injury.
,Caution
Indicates a hazardous situation that, if not avoided,
could result in minor or moderate injury.
Notice
Indicates information considered important, but not
hazard-related (e.g. messages relating to property
damage).
NOTE: Indicates useful, extra information about the
procedure you are performing.

nWarning
Follow these electrical requirements during
installation of this equipment:
• All field wiring must conform to all applicable
codes of the authority having jurisdiction. It is
the responsibility of the end user to provide the
disconnect means to satisfy local codes. Refer to
rating plate for proper voltage.
• This appliance must be grounded.
• This equipment must be positioned so that the plug
is accessible unless other means for disconnection
from the power supply (e.g., circuit breaker or
disconnect switch) is provided.
• Check all wiring connections, including factory
terminals, before operation. Connections can
become loose during shipment and installation.

nWarning
Follow these precautions to prevent personal injury
during installation of this equipment:
• Installation must comply with all applicable
equipment fire and health codes with the authority
having jurisdiction.
• Connect to a potable water supply only.
• To avoid instability the installation area must be
capable of supporting the combined weight of the
equipment and product. Additionally the equipment
must be level side to side and front to back.
• Remove all removable panels before lifting and
installing and use appropriate safety equipment
during installation and servicing. Two or more
people are required to lift or move this appliance to
prevent tipping and/or injury.
• Do not damage the refrigeration circuit when
installing, maintaining or servicing the unit.
• This equipment contains refrigerant charge.
Installation of the line sets must be performed by
a properly trained and EPA certified refrigeration
technician aware of the dangers of dealing with
refrigerant charged equipment.
• Ice machines require a deflector when installed on
an ice storage bin. Prior to using a non-OEM ice
storage system with this ice machine, contact the
bin manufacturer to assure their ice deflector is
compatible.
• Prior to installing a non-OEM ice storage system
with this ice machine, follow the manufacturers
installation procedures and verify the location and
installation meets the local/national mechanical
codes and stability requirements.

nWarning
Follow these precautions to prevent personal injury
while operating or maintaining this equipment:
• Legs or casters must be installed and the legs/casters
must be screwed in completely. When casters
are installed the mass of this unit will allow it to
move uncontrolled on an inclined surface. These
units must be tethered/secured to comply with all
applicable codes. Swivel casters must be mounted
on the front and rigid casters must be mounted on
the rear. Lock the front casters after installation is
complete.
• Refer to nameplate to identify the type of refrigerant
in your equipment.
• Only trained and qualified personnel aware of the
dangers are allowed to work on the equipment.
• Read this manual thoroughly before operating,
installing or performing maintenance on the
equipment. Failure to follow instructions in this
manual can cause property damage, injury or death.
• Crush/Pinch Hazard. Keep hands clear of moving
components. Components can move without
warning unless power is disconnected and all
potential energy is removed.
• Moisture collecting on the floor will create a
slippery surface. Clean up any water on the floor
immediately to prevent a slip hazard.

nWarning
Follow these precautions to prevent personal injury
while operating or maintaining this equipment:
• Objects placed or dropped in the bin can affect
human health and safety. Locate and remove any
objects immediately.
• Never use sharp objects or tools to remove ice or
frost.
• Do not use mechanical devices or other means to
accelerate the defrosting process.
• When using cleaning fluids or chemicals, rubber
gloves and eye protection (and/or face shield) must
be worn.
DANGER
Do not operate equipment that has been misused,
abused, neglected, damaged, or altered/modified
from that of original manufactured specifications. This
appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental

during use and maintenance of this equipment:
• It is the responsibility of the equipment owner to
perform a Personal Protective Equipment Hazard
Assessment to ensure adequate protection during
maintenance procedures.
• Do Not Store Or Use Gasoline Or Other Flammable
Vapors Or Liquids In The Vicinity Of This Or Any
Other Appliance. Never use flammable oil soaked
cloths or combustible cleaning solutions for
cleaning.
• All covers and access panels must be in place and
properly secured when operating this equipment.
• Risk of fire/shock. All minimum clearances must be
maintained. Do not obstruct vents or openings.
• Failure to disconnect power at the main power
supply disconnect could result in serious injury or
death. The power switch DOES NOT disconnect all
incoming power.
• All utility connections and fixtures must be
maintained in accordance with the authority having
jurisdiction.
• Turn off and lockout all utilities (gas, electric, water)
according to approved practices during maintenance
or servicing.
• Units with two power cords must be plugged
into individual branch circuits. During movement,
cleaning or repair it is necessary to unplug both
power cords.
