2. Harvest Time (S1 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 (S1 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 (S1 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.
3. Pump-Out Time/Harvest Time During Pump-Out (S1 dip switch 3 & 4)
When a pump-out is called for, the pump motor stops for 2 seconds, then the pump
motor and drain valve energize. Water is removed from the bottom of the water tank
and sent down the drain. The pump-out 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 set, and generally no adjustment
is required. The pump-out timer control can be set to pump-out for 10 or 20 seconds.
During pump-out cycles minimum harvest time is based on times given in the
table below.
