3. Controls and Adjustments

Dip switches are factory set. Failure to maintain factory settings may adversely
affect performance and warranty coverage. For more information, contact
Hoshizaki Technical Support at 1-800-233-1940.

a) Default Dip Switch Settings

The dip switches are factory set to the following positions:
S4 Dip Switch No.
KM-1301SAH/3
KM-1301SWH/3
KM-1301SRH/3
S5 Dip Switch (Do Not Adjust)

b) Harvest Timer (S4 dip switch 1 & 2)
The harvest timer starts when the thermistor reads 48°F (9°C) at the evaporator outlet
and the control board reads the thermistor's 3.9 KΩ signal. The harvest timer is factory
set, and generally no adjustment is required. However, a setting longer than the factory
setting may be advised in cases where the flush provided at harvest needs to be
prolonged for extra cleaning. Before changing this setting, contact Hoshizaki Technical
Support at 1-800-233-1940 for recommendations. Keep in mind that setting the harvest
timer to a longer setting decreases 24-hour production.
