Notes
The sizing of effluent systems normally requires variable level float(s) controls and properly sized basins to achieve required pumping cycles or dosing timers with non-automatic pumps.
Pumps must be operated in upright position.
Reserve Powered Design.
For unusual conditions a reserve safety factor is engineered into the design of every Zoeller pump.
