c) 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 
-800-33-940 for recommendations. Keep in mind that setting the harvest timer to a 
longer setting will decrease 4 hour production.

d) Pump-Out Timer (dip switch 3 & 4)
When a freeze cycle is completed, the pump motor stops, and the icemaker resumes 
operation in  seconds. Then, during cycles when a pump out is called for, the pump 
motor drains the water tank for the time determined by the pump-out timer. The pump-
out timer also acts in place of the harvest timer during cycles with a pump out.
The pump-out timer is factory-adjusted, and no adjustment is required.
