On some installations, it may be desirable
to install an independent hanger for the
level control switches to avoid possible
hang-ups on the pumps, piping, valves,
etc. Float hangers are available from
Zoeller Company on Catalog Sheet FM0526
or can be fabricated from standard pipe
and fittings.

1. Electrical wiring and protection must be in accordance with governing
electrical codes.
2. Install proper Zoeller Unicheck (combination union and check valve),
preferably just above the basin to allow easy removal of the pump
for cleaning or repair. If high head or below-cover installation is
required, use 30-0164 on 1-1/2" (DN40) pipe, 30-0152 on 2" (DN50) pipe
and 30-0160 on 3" (DN80) pipe.
3. All installations require a basin cover to prevent debris from falling into
the basin and to prevent injury.
4. When a Unicheck is installed, drill a 3/16" (5 mm) diameter hole in the
discharge pipe even with the top of the pump.
NOTE: THE HOLE MUST
ALSO BE BELOW THE BASIN COVER AND CLEANED PERIODICALLY.
(High Head unit see “Caution” on front page). Water stream will be
visible from this hole when pump is operating.
5. Securely tape or clamp power cord to discharge pipe, clear of the float
mechanism(s).
6. Use a discharge pipe equivalent in diameter to the pump's discharge.
7. Basin must be in accordance with governing codes and specifications.
8. Pump must be level and float mechanism(s) clear of sides of basin
before starting pump.
9. Basin must be clean and free of debris after installation.
10. Gate valve, shut-off valve, or ball valve to be supplied by installer and
installed according to any and all codes.
11. Locate float switches as shown in sketches. The best place for the “off”
point is above the motor housing and positioned 180° from the inlet.
Never put “off” point below discharge on pump
12. Gas-tight seals are required to contain gases and odors.
13. Vent gases and odors to the atmosphere through vent pipe. Must comply
with local codes but not required for dewatering.
14. Optional pump stand (P/N 10-2421) eliminates the need for blocks or
bricks under the pump. For use with effluent and dewatering pumps only.
15. Optional watertight control box available, see FM1597 for details.
16. For proper spacing of "On" - "Off" switches refer to local or
national standards and guidelines.
17. Optional septic tank risers for easy access to pump, controls and filters.
