8. 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 or pump-out cycle. After 2 consecutive freeze timer terminations, the
control board shuts down the icemaker. In this case, see "II.I.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.
9. Float Switch Control Selector for Refill (S5 dip switch 1)
Do not adjust. This must be left in the factory default position or the icemaker will
not operate correctly. This setting is ignored if refill counter (S5 dip switch 2 and 3)
set to 0. The KMS-1122MLJ uses a single float switch with no refills.
Float switch control selector for refill is used in applications where refill is required in the
freeze cycle.
• With S5 dip switch 1 in the "OFF" position, control board monitors the lower float switch
for refill operation.
• With S5 dip switch 1 in the "ON" position, the control board monitors the upper float
switch for refill operation. If single float, no upper float switch exists, therefore
the control board reads an open upper float switch immediately when the freeze
cycle starts and initiates a refill. Since there is no upper float switch to close and
terminate the refill, the refill lasts for a maximum of 1-min. and occurs 1 time only.
During the 1-min. refill, LED 4 is on.
