Operational Checks
GENERAL
Manitowoc ice machines are factory-operated and
adjusted before shipment. Normally, a newly installed ice
machine does not require any adjustment.
To ensure proper operation, always follow the
Operational Checks:
• when starting the ice machine for the first time
• after a prolonged out of service period
• after cleaning and sanitizing
NOTE: Routine adjustments and maintenance
procedures outlined in this manual are not covered by
the warranty.
