2. Harvest Timer (S4 dip switch 1 & 2)
The harvest timer starts counting when the thermistor reaches 48°F (9°C) at the
evaporator outlet and the control board reads 3.9 kΩ from the thermistor. 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 drain provided at harvest
needs to be prolonged for extra cleaning. Note that the pump-out timer (S4 dip switch
3 & 4) acts in place of the harvest timer during cycles with a pump out. For details, see
"III.C.3. Pump-Out Timer (S4 dip switch 3 & 4)."
Note: On models with a pump-out every cycle, the harvest timer is only relevant during
the initial harvest cycle since a pump out occurs every cycle thereafter.
