RECOMMENDED INSTALLATION FOR ALL APPLICATIONS
PERFORMANCE DATA
(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 (indoor installations) 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 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)
For nonautomatic pumps, 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 required to contain gases and odors.
(13) Vent gases and odors to the atmosphere through vent pipe.
All installations must comply with all applicable
electrical and plumbing codes.

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.
