ICE THICKNESS PROBE (INITIATES HARVEST)
FUNCTION
The ice thickness probe senses ice on the evaporator and
signals the control board to start a harvest cycle.
SPECIFICATIONS
Freeze Time Lock-In Feature
The ice machine control system incorporates a 6 minute
freeze time lock-in feature. This prevents the ice machine
from short cycling in and out of harvest.
Maximum Freeze Time
The maximum freeze time is 35 minutes at which time the
control board automatically initiates a harvest sequence.
Maximum Temperature
Maximum temperature for the ice thickness probe is 120°F
(49°C). Do not clean probe in a dishwasher or expose to
temperatures above the maximum.
