SAFETY LIMITS
Safety limits are stored and indicated by the control board.
The number of cycles required to stop the ice machine
varies for each safety limit.
Safety limits can be reset by cycling the toggle switch Off/
On and starting a new ice making cycle.
A safety limit is indicated by a flashing light on the control
board.
Safety Limit 1
If the freeze time reaches 60 minutes, the control board
automatically initiates a harvest cycle.
• After 3 consecutive 60 minute cycles, control board
light SL#1 light will flash on/off at 1 second intervals.
• If 6 consecutive 60-minute freeze cycles occur, the ice
machine stops and the SL#1 light on the control board
will be on continuously.
Safety Limit 2
If the harvest time reaches 3.5 minutes, the control board
automatically returns the ice machine to the freeze cycle.
• If three consecutive 3.5 minute harvest cycles occur,
the SL#2 light on the control board will flash on/
off at 1 second intervals. After 75 consecutive 3.5
