b) Harvest Timer (S4 dip switch 1 & 2)
The harvest timer 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
-800-33-940 for recommendations. Keep in mind that setting the harvest timer to a
longer setting decreases 4-hour production.
