Note: Normal freeze cycle will last 20 to 40 minutes depending on model and conditions. Cycle times and pressures should follow performance data provided in this manual.
6)
2 seconds and starts in reverse rotation for 10/20 seconds. (This removes contaminants from the water reservoir through the check valve (drain valve) and down the drain and allows for a power flush of the float switch.) Check for clear tubing at the check valve housing and check the unit drain for water flow. Diagnosis: If the pump motor does not reverse, check the circuit and capacitor. If water does not pump out, remove the check valve (drain valve) housing and check/clean the valve assembly.
7)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 pump out cycle can be adjusted to occur every cycle, or every 2, 5, or 10 cycles. The factory default is every 10 cycles.) The unit always restarts at the 1 minute fill cycle.
