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 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 decreases 24-hour production.
Note that the pump-out timer (S4 dip switch 3 & 4) acts in place of the harvest timer
duringcycleswithapump-out.Fordetails,see"II.C.2.c)Pump-OutTimer(S4dipswitch
