Freeze Timer (S4 Dip Switch 9 & 10); Float Switch Selector (S5 Dip Switch 1) - Hoshizaki KMS-1122MLH Service Manual

7. Freeze Timer (S4 dip switch 9 & 10)
Adjust to proper specification, 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. After 2 consecutive freeze timer terminations, the control board shuts down
the appliance. In this case, see "II.G.3. Low Ice Production" for possible solutions.
The freeze timer is factory set, and generally no adjustment is required. Before changing
this setting, contact your local Hoshizaki distributor or Hoshizaki Technical Support for
recommendations.

8. Float Switch Selector (S5 dip switch 1)

Do not adjust. This must be left in the factory default position or the appliance will
not operate correctly.
On appliances with a double float switch, the float switch selector determines which float
switch (upper or lower) the control board monitors for refill initiation during the freeze
cycle. The refill counter (S5 dip switch 2 through 5) determines the number of refills. The
KMS-1122MLH uses a single float switch and does not refill during the freeze cycle.
