Warning
When installing, using, or servicing this equipment,
follow these flammable refrigeration system
requirements.
• Refer to the nameplate - The ice machine 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.
R290 (propane) may burn if exposed to a heat source
above 470 °C. Refer to nameplate to identify the type
of refrigerant in your equipment.
• To reduce the risk of fire due to improper installation,
replacement of parts, or improper use of procedures,
only refrigeration technicians trained in flammable
refrigerants who understand the dangers of high
voltage electricity and refrigerants under pressure are
allowed to work on this equipment.
• Only use parts recommended or provided by the
manufacturer.
• This equipment must be installed in accordance with
ASHRAE 15 refrigeration system’s safety standards.
• This equipment cannot be installed in a corridor or
hallway of a public building.
• Equipment installation must comply with local
sanitation and fire regulations.
• When servicing this equipment, be sure to lock the
circuit breaker, and display an in-service notice.
• This device contains a high-voltage power supply
and refrigerant charge. Shorting wires to the cooling
system piping may cause an explosion. Before servicing
the system, be sure to disconnect all power to the
system. Refrigerant leakage can result in serious
injury or death from explosion, fire, or contact with
refrigerant or lubricant mist.
• Do not damage the refrigeration circuit when
installing, maintaining or servicing the unit.
