about the procedure you are performing.

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.
• 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.
• 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.
• 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.
• 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.
• Connect to a potable water supply only.
• 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.

DANGER
Follow these flammable refrigeration system requirements during installation, use or
repair of this equipment:
• Refer to nameplate - Ice machine models
may contain up to 150 grams of R290
(propane) refrigerant. R290 (propane)
is flammable in concentrations of air
between approximately 2.1% and 9.5%
by volume (LEL lower explosion limit and
UEL upper explosion limit). An ignition
source at a temperature higher than
470°C is needed for a combustion to
occur. Refer to nameplate to identify the
type of refrigerant in your equipment.
• To minimize the risk of ignition due to
improper installation, replacement parts
or service procedures, only refrigeration
technicians with flammable refrigerant
training who are aware of the dangers of
dealing with high voltage electricity and
refrigerant under pressure are allowed to
work on this equipment.
• All replacement parts must be like
components obtained from the
equipment manufacturers authorized
replacement part network.
• This equipment must be installed in
accordance with the ASHRAE 15 Safety
Standard for Refrigeration Systems.
• This equipment can not be installed in
corridors or hallways of public buildings.
• Installation must comply with all
applicable equipment fire and health
codes with the authority having
jurisdiction.
• All lockout and tag out procedures
must be followed when working on this
equipment.
• This equipment contains high voltage
electricity and refrigerant charge.
Shorting electrical wires to refrigeration
tubing may result in an explosion. All
electrical power must be disconnected
from the system before servicing the
system. Refrigerant leaks, can result in
serious injury or death from explosion,
fire, or contact with refrigerant or
lubricant mists.
• Do not damage the refrigeration circuit
when installing, maintaining or servicing
the unit. Never use sharp objects or
tools to remove ice or frost. Do not use
mechanical devices or other means to
accelerate the defrosting process.

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.
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 capabilities,

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.
• 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
Follow these precautions to prevent personal injury 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

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.
• Never use a high-pressure water jet for
cleaning on the interior or exterior of
this unit. Do not use power cleaning
equipment, steel wool, scrapers or wire
brushes on stainless steel or painted
surfaces.
• Two or more people are required to
move this equipment to prevent tipping.
• Locking the front casters after
moving is the owner’s and operator’s
responsibility. When casters are installed,
the mass of this unit will allow it to move
