4. Controls and Adjustments
CAUTION
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-adjusted to the following positions:
S4 Dip Switch
S4 Dip Switch No. 1 2 3 4 5 6 7 8 9 10
KM-2500SWH3 OFF OFF OFF OFF OFF OFF OFF OFF OFF ON
KM-2500SRH3 OFF OFF OFF OFF OFF OFF OFF OFF OFF ON
b) Harvest Timer (S4 dip switch 1 & 2)
The harvest timer starts when the thermistor warms to 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 ush 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 will decrease 24 hour production.
Note that the pump-out timer (S1 dip switch 3 & 4) acts in place of the harvest timer
during cycles with a pump-out. For details, see "II.C.4.c) Pump-Out Timer (S1 dip
switch 3 & 4)."
