8. Freeze Timer (S4 dip switch 9 & 10)
NOTICE
Adjust to proper specication, or the icemaker may not operate correctly.
The freeze timer setting determines the maximum allowed freeze time to prevent
possible freeze-up issues. Upon termination of the freeze timer, the control board initiates
the harvest cycle or pump-out cycle. After 2 consecutive freeze timer terminations, the
control board shuts down the icemaker. In this case, see "II.H.3. Low Ice Production"
for possible solutions. The freeze timer is factory set and no adjustment is required.
Before changing this setting, contact Hoshizaki Technical Support at 1-800-233-1940 for
recommendations.
