C) Harvest Timer (Dip Switch 1 & 2); D) Pump-Out Timer (Dip Switch 3 & 4) - Hoshizaki KM-1340MAH Service Manual

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
1-800-233-1940 for recommendations. Keep in mind that setting the harvest timer to a
longer setting will decrease 24 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 2 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.
T1: Time to drain the water tank
T2: Harvest timer at pump out
Pump out always occurs on the 2nd harvest after startup. Then, depending on the pump-
out frequency control setting (dip switch 5 & 6), pump out occurs every cycle, or every
2nd, 5th or 10th cycle.
