b) Harvest Timer (S4 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 setting. 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 1-800-33-1940
for recommendations. Keep in mind that setting the harvest timer to a longer setting will
decrease 4 hour production.
