G) Freeze Timer (S4 Dip Switch 9 & 10); H) Float Switch Control (S5 Dip Switch 1): "G" Control Board; I) Refill Counter (S5 Dip Switch 2 Through 5): "G" Control Board - Hoshizaki KM-901MAH Service Manual

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.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.

h) Float Switch Control (S5 dip switch 1): "G" Control Board

Do not adjust. This must be left in the factory default position or the unit will not
operate correctly.
Factory set. S5 dip switch 1 allows for single or double float switch applications. The
KM-901MAH, KM-901MWH, and KM-901MRH/3 use a single float switch.

i) Refill Counter (S5 dip switch 2 through 5): "G" Control Board

Do not adjust. These must be left in the factory default position or the unit will
not operate correctly.
Factory set. S5 dip switch 2 through 5 allows for refills during the freeze cycle. The
KM-901MAH, KM901MWH, and KM-901MRH/3 do not refill.
