Operational Checks
GENERAL
Your Manitowoc ice machine was factory-operated and
adjusted before shipment. Normally, a newly installed ice
machine does not require any adjustment.
To ensure proper operation, always follow these
Operational Checks when starting the ice machine:
• for the first time
• after a prolonged out of service period
• after cleaning and sanitizing
Routine adjustments and maintenance procedures
outlined in this manual are not covered by the warranty.
SIPHON SYSTEM
To reduce mineral build-up and cleaning frequency, the
water in the sump trough must be purged during each
harvest cycle.
When the water pump de-energizes the level in the
water trough rises above the standpipe starting a siphon
action. The siphon action stops when the water level in
the sump trough drops. When the siphon action stops,
the float valve refills the water trough to the correct level.
Siphon System Check
Follow steps 1 through 6 under water level check.
WATER FLOAT VALVE CHECK
Before water will flow into the water trough the float
valve shut-off must be in the OPEN position.
