Hoshizaki KM-901MRH/3, KM-901MWH Freeze Timer S4 dip switch 9, S4 Dip Switch Setting Time Minutes

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.
