* May be used in those states where codes do not restrict solids size in effluent systems.

** See charts for UL and CSA listings.

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.

Reserve powered design.

For unusual conditions a reserve safety factor is engineered into the design of every Zoeller® pump.
