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.

RECOMMENDED INSTALLATION FOR ALL APPLICATIONS
All installations must comply with all applicable electrical and plumbing codes, including, but not limited to, National Electrical Code, local, regional, and/or state plumb-
ing codes, etc. Not intended for use in hazardous locations.
(1) Electrical wiring and protection must be in accordance with National
Electrical Code and any other applicable state and local electrical
requirements.
(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. On sewage, effluent or dewatering, if high head or
below cover installation is required use 30-0164 on 1-1/2" pipe, 30-0152 on
2" pipe and 30-0160 on 3" pipe. See (4) below.
(3) All installations require a basin cover to prevent debris from falling into
the basin and to prevent accidental injury.
(4) When a Unicheck is installed, drill a 3/16" (5 mm) dia. 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 #3 under “Caution” on front page). Water stream will be visible
from this hole during pump run periods.
(5) Securely tape or clamp power cord to discharge pipe, clear of the float
mechanism(s).
(6) Use full-size discharge pipe.
(7) Basin must be in accordance with applicable 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 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 (Sewage &
Effluent only).
NOTE: FOR AUTOMATIC PUMPS, USE DEWATERING
INSTALLATION SKETCH.
(12) Gas tight seals 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) Install Zoeller Pump Stand (10-2421) under pump to provide a
settling basin. (Effluent & Dewatering only.)
For Effluent Only:
(15) Wire pump to power through a Zoeller watertight junction box or
watertight splice.
NOTE: Watertight enclosure is a must in damp areas.
See No. 8 on front page of FM0732.
(16) Refer to SSPMA Effluent Sizing Manual for determining “on” - “off”
switches.
(17) Septic tank risers must be used for easy pump and filter access.
NOTE:
Double seal pumps offer extra protection from damage caused by seal
failure.
