• 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.
