(2) Bin Control Selector, KM-1601SWH/3 & KM-1601SRH/3 "E" Control Board
Factory set for proper operation. Do not adjust. When set to the on position on a unit
with a thermostatic bin control, a 5-beep alarm sounds (open circuit) and the unit does
not operate.

f) Factory Use (S4 dip switch 8)

Factory set. Do not adjust. This must be left in the factory default position.
g) Freeze Timer (S4 dip switch 9 & 10)
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.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 Hoshizaki Technical Support at 1-800-233-1940 for recommendations.

h) Float Switch Selector (S5 dip switch 1), KM-1601SAH/3 "G" Control Board

Factory set. Do not adjust. This must be left in the factory default position or the
unit will not operate correctly.
S5 dip switch 1 allows for single or double float switch applications. The KM-1601SAH/3
use a single float switch.

i) Refill Counter (S5 dip switch 2 through 5), KM-1601SAH/3 "G" Control Board
