3. Controls and Adjustments

a) Default Dip Switch Settings

The dip switch is factory-adjusted to the following positions:
Dip Switch No.
KML-451MAH
KML-451MWH
b) Harvest Timer (dip switch 1 & 2)
The harvest timer starts counting when the thermistor reads 48°F (9°C) at the evaporator
outlet.
No adjustment is required under normal use, as the harvest timer is adjusted to the
suitable position. 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, call the HOSHIZAKI Technical Support Department at
1-800-233-1940 for recommendations. Keep in mind that setting the harvest timer to a
longer setting will decrease 24 hour production.
