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.

o) Anti-Slush Control (S2 dip switch 6) [Program Ver. 3.1]
Do not adjust. This must be left in the factory default position or the unit will not operate
properly.
It is deactivated on the KMD-410 series.
When activated (Ver. 2.0), the thermistor located on the suction line checks for a 50°F
(10°C) temperature as the evaporator cools. When 50°F (10°C) is reached, a 3.9 kŸ signal
causes the control board to de-energize the pump motor for 10 seconds and energize it for
50 seconds repeatedly. When 34°F (1°C) is reached, a 5.9 kŸ signal causes the control
board to de-energize the pump motor for 10 seconds, energize it for 50 seconds,
de-energize it again for 10 seconds, then energize it continuously.

When activated (Ver. 1.1), the thermistor located on the suction line checks for a 41°F (5°C)
temperature as the evaporator cools. When 41°F (5°C) is reached, a 4.8 kŸ signal causes
the control board to de-energize the pump motor for 10 seconds.
