g) Freeze Timer (S4 dip switch 9 & 10)
CAUTION
Adjust to proper specification, or the unit 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. After 2 consecutive freeze timer terminations, the control
board shuts down the icemaker. In this case, see "IV.F.3. Low Ice Production" for
possible solutions. The freeze timer is factory set, and generally no adjustment
is required. Before changing this setting, contact Hoshizaki Technical Support at
1-800-233-1940 for recommendations.
