SINGLE PHASE PUMPS
PLUG-CONNECTED UNITS MUST

BE CONNECTED TO A PROPERLY
GROUNDED, GROUNDING TYPE RE-
CEPTACLE.
ON NON-PLUG UNITS, DO NOT RE-
MOVE CORD AND STRAIN RELIEF. DO
NOT CONNECT CONDUIT TO PUMP.
Hazardous voltage
can shock, burn or
cause death.
Pumps with bare lead power cords can be hard-wired to
a float switch, wired to a 1Ø contactor, a Simplex con-
troller or a Duplex controller. Always verify that the float
switch is rated for the maximum run amperage, maxi-
mum starting amperage, and the HP rating on the pump.
Single-phase wastewater pumps contain on-winding
overloads, unless noted on the pump nameplate. See
Figure 1.
SINGLE PHASE CONTROL PANELS:
Control panels are available as Simplex (controls 1 pump)
or Duplex (controls 2 pumps). Our standard control
panels are available with many standard features and can
be built with our most popular options. We also custom
build panels which offer many more design options than
the standard panels. Custom control panels are available
in many different configurations. Custom panel quote
requests may be forwarded to Customer Service through
any authorized distributor.
Our standard duplex panels feature a solid-state printed
circuit board design with standard high level alarm cir-
cuits. Other standard features are: an auxiliary dry alarm
contact for signaling a remote alarm and float switch po-
sition indicator lights. Most standard panels are in stock
for immediate delivery.

INSTALLATION

STANDARD PUMP INSTALLATION
Connect the pump(s) to the guide rail pump adapters
or to the discharge piping. Guide rail bases should be
anchored to the wetwell floor.
Complete all wiring per the control panel wiring dia-
grams and NEC, Canadian, state, provincial and/or local
codes.
DO NOT PLACE HANDS IN PUMP
DANGER
!
SUCTION WHILE CHECKING
MOTOR ROTATION. TO DO SO WILL
CAUSE SEVERE PERSONAL INJURY.
Lower the pump(s) into the wetwell.
Check to insure that the floats will oper-
ate freely and will not contact the piping.
Hazardous Machinery
Connect the piping per local codes and
the drawings in Typical Drawings Section.

OPERATION

Once the piping connections are made and checked you
can run the pumps.
Hard Wired Float Switch Operation – Turn circuit
breaker or fused disconnect to On. Test the pump by
filling the wetwell until the pump goes On. If the pumps
run but fail to pump, they are probably air locked, drill the
relief holes per the instructions in the Piping Section.
Check the operating range to insure a minimum two min-
ute run time and that the pump goes Off in the correct
position.
Control Panel Operation – Fill the wetwell with clear
water.
Use the pump H-O-A (Hand-Off-Automatic) switches in
Hand to test the pumps. If they operate well in Hand pro-
ceed to test Automatic operation. If the pumps run but
fail to pump, they are probably air locked, drill the relief
holes per the instructions in the Piping Section.
Place Control Panel switch(es) in Automatic position and
thoroughly test the operation of the ON, OFF, and Alarm
floats by filling the wetwell with clear water. Important:
Failure to provide a Neutral from the power supply to a
1Ø, 230 volt Control Panel will not allow the panel control
circuit to operate. The Neutral is necessary to complete
the 115 volt control circuit.
Check voltage and amperage and record the data on the
front of this manual for future reference. Compare the
amperage readings to the pump nameplate maximum
amperage. If higher than nameplate amperage investi-
gate cause. Operating the pump off the curve, i.e. with
too little head or with high or low voltage will increase
amperage. The motor will operate properly with voltage
not more than 10% above or below pump nameplate
ratings. Performance within this range will not necessarily
be the same as the published performance at the exact
rated nameplate frequency and voltage. Correct the
problem before proceeding.
Reset the Alarm circuit, place pump switch(es) in the Au-
tomatic position and Control Switch in ON position. The
system is now ready for automatic operation.
Explain the operation of the pumps, controls and alarms
to the end user. Leave the paperwork with the owner or
at the control panel if in a dry, secure location.
