k) Refill Counter (S2 dip switch 3) [Program Ver. 3.1, Ver. 3.2]
Do not adjust. This must be left in the factory default position or the unit will not operate
properly. The KM-100A and KM-125A do not refill.
l) Harvest Completion Detection Control (S2 dip switch 4) [Program Ver. 3.1, Ver.
3.2]
Do not adjust. This must be left in the factory default position or the unit will not operate
properly.
It is deactivated on the KM-100A and KM-125A.
When activated, this control determines whether ice remains on the evaporator at the
end of a harvest cycle and at the beginning of a freeze cycle. If ice drops and activates
the bin control switch in the last 10 seconds of a harvest cycle, the control determines
that ice still remains on the evaporator and extends the harvest cycle for 30 seconds.
If the bin control switch is activated at the beginning of a freeze cycle, the control
determines that ice still remains on the evaporator and starts a harvest cycle after the
minimum freeze cycle time has passed.

m) Overfreeze Detection Control (S2 dip switch 5) [Program Ver. 3.1, Ver. 3.2]
Do not adjust. This must be left in the factory default position or the unit will not operate
properly.
It is deactivated on the KM-100A and KM-125A.
When activated, the thermistor detects the temperature of the evaporator outlet to find
overfreeze in a harvest cycle and at the beginning of a freeze cycle. If the difference
between the maximum temperature after the water saver timer starts counting and the
temperature at the end of a harvest cycle is 4K or more and if the temperature at the end
of a harvest cycle is 48°F (9°C) or less, the harvest cycle is extended for 30 seconds.
If the difference between the temperature at the beginning of a freeze cycle and the
minimum temperature after 30 seconds in the freeze cycle is 2.5K or more and less than
3.5K, the next harvest cycle is extended for 30 seconds. If the above conditions occur
in succession, the number of occurrence times 30 seconds will be added to the harvest
cycle time. If the above temperature difference is 3.5K or more, the freeze cycle ends
after the minimum freeze cycle time and a harvest cycle starts.
