nWarning

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.
