2. Valve clutch engages 5 seconds after pump clutch engages.
Aerate SHUT-DOWN Sequence (Neutral Delay)
1. Pump clutch disengages and green light goes off 4 seconds after transport switch opens (red light goes off).
2. After another 3 seconds, valve clutch will disengage.
NOTE: Keeping aerate start (engage) switch pushed in (closed) will keep green light on and override neutral delay
shut-down.
Aerate SHUT-DOWN Sequence (Disengage Delay)
1. Pump clutch disengages and green light goes off immediately when stop (disengage) switch is pushed in (opens)
or if pump start limit switch or water pressure switch opens (yellow light goes off).
