• Electrical service must fall within the voltage tolerances listed below:
• Breaker or fuse service must be no greater than the maximum rating as specified on the
rating label attached to the back of the machine.
• The minimum circuit ampacity listed on the back of the machine does not indicate a typical
running current value. Use the minimum ampacity value for sizing branch circuit conductors
up to 26 feet (8 meters) in length. For a conductor length over this length, increase the wire
gauge as required by code.
Warning: Water Treatment: There are no specific requirements for water treatment provided
that the ice making supply water is potable and not laden with sediment. The use of
additional water treatment may facilitate or reduce the frequency of the need
for cleaning. Please consult your local water conditioning supplier for specific
recommendations.
Note:
• Ambient temperatures higher than the maximum specification will result in reduced
capacities and high system pressures in air-cooled models. Temperatures lower than the
minimum will cause the machine to malfunction due to an inability to eject the ice from the
evaporator. Ambient temperatures less than 60°F (15°C) may cause the bin thermostat to
malfunction.
• Clearance must be provided for ventilation and access for service. Ventilation is
especially important for models with air-cooled condensers. Failure to provide adequate
clearance may result in reduced capacities and high system pressures.
• Ice machine drains and bin drains may be insulated to prevent condensation.
• The use of water treatment may increase the intervals between cleaning operations and
the overall machine life.
• If a water pressure regulator is used, the recommended setting is 30 to 50 psig (0.2 MPa
to 0.3 MPa) dynamic.
• Do not connect the ice machine to a hot water supply line. Insulate the water line from
sources of heat for greater operating efficiency. Supply water temperatures higher than the
recommended maximum will cause reduced capacities.
• Normal protector size is based on rated voltage and operation at lower than extreme
temperature limits. Branch circuit conductors may be sized to allow increasing the
protector value up to the specified maximum. This may avoid nuisance protector opening
under harsh operating conditions.
