Pump-Out Cycle
– The 1st pump out occurs after the 11th freeze cycle and every
10th cycle thereafter. LEDs 1, 3, are on. The compressor and fan motors remain
energized. The drain water valve, hot gas valves and X1 relay energize, the liquid line
valves de-energize. The pump motor stops for seconds then restarts for 10 seconds
(pump out frequency can be adjusted on S4 dip switches 5 and 6). This pump out
removes contaminants from the water reservoir through the drain water valve and
allows for a power flush of the float switch.
Diagnosis:
If the pump motor does not
come on, check the circuit and capacitor. If water does not pump out, remove the drain
water valve housing and check/clean the valve assembly, check for voltage on the
drain valve coil with LED 3 on, make sure that the drain line is not clogged.

Normal Harvest Cycle
– Same as the initial harvest cycle. Return to step 4.
Note: Unit continues to cycle until bin control is satisfied or power is switched off. The
unit always restarts at the 1 minute fill cycle.
