and/or the motor start switch and/or the float switch. If
using single action switches with a control panel please
see the Float Switch and Panel Section.
Vertical mechanical float switches with piggyback plugs
are available for single phase pumps. They are an ideal
choice where there is limited space for a switch. They
require less room than a wide angle switch because they
travel in a vertical direction. Typical model numbers start
with A2H...
Wide angle float switches are the most popular type.
They can be directly connected to a pump or to a control
panel. The "tether length" or the distance from the switch
body to the pivot point controls the On and Off points
and the amount pumped in one cycle. The pivot point
is where the float is attached either to the pump or the
discharge pipe. See Figures 1 - 5.
SETTING THE FLOAT SWITCHES
There are no absolute rules for where to set the float
switches, it varies from job to job.
Suggested Rules to Follow:
All floats should be set below the Inlet pipe!
Off Float: Best: set so the water level is always above the
top of the pump (motor dome). Next Best: set so the wa-
ter level is not more than 6" below the top of the pump.
On Float: set so the volume of water between the On
and Off floats allows pumps of 1½ HP and under to oper-
ate for 1 minute minimum. Two (2) HP and larger pumps
should run a minimum of 2 minutes. Basin literature
states the gallons of storage per inch of basin height.
Lag/Alarm Float(s): should be staggered above the
Off and On floats. Try to use most of the available stor-
age provided by the basin, save some space for reserve
storage capacity. See Diagrams and Charts in Float Switch
Chart Section.
PANEL WIRING DIAGRAMS
Our control panels are shipped with instructions and
wiring diagrams. Use those instructions in conjunction
with this IOM. Electrical installation should be performed
only by qualified technicians. Any problem or questions
pertaining to another brand control must be referred
to that control supplier or manufacturer. Our technical
people have no technical schematics or trouble shooting
information for other companies' controls.
ALARMS
We recommend the installation of an alarm on all Waste-
water pump installations. Many standard control panels
come equipped with alarm circuits. If a control panel is
not used, a stand alone high liquid level alarm is avail-
able. The alarm alerts the owner of a high liquid level in
the system so they can contact the appropriate service
personnel to investigate the situation.
SINGLE PHASE PUMPS
Single phase (1Ø) pumps may be operated using a
piggyback or hard wired float switch, a contactor, or a
Simplex or Duplex control panel. See Figures 1, 2 and 5.
All
/
and ½ HP, 115 or 230 volt pumps, and some ¾ and
1
3
1 HP pumps, are supplied with plug style power cords.
They may be plugged into piggyback float switches for
simple installations. It is allowable to remove the plugs
in order to hardwire or connect to a Simplex or Duplex
controller. Removing the plug neither voids the warranty
nor violates the agency Listings. See Figure 5.
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 waste water pumps contain on-winding
overloads, unless noted on the pump nameplate. See
Figures 1 and 2.
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 IN SUMP WITHOUT
SLIDE RAILS
Is your basin sized correctly and the proper type for the
location?
Diameter - It must be wide enough to allow the pump
and switch to physically fit and provide room for the
switch to operate freely. The vertical switch models
typically require less diameter than the wide-angle
float models. See "min. basin diameter" in Chart 1.
Depth - It must be deeper than the
CAUTION
minimum depth at which the switch
turns the pump On. As an example, if the pump turns
on at 15" you want to use a basin deeper than 15".
See "On level" in Chart 1.
Style - There are several sump basin
WARNING
styles available. The location of the
sump determines if you require a cover and what type
you require. It is important to keep debris from enter-
ing the sump and clogging the pump. An open sump
in a traffic area such as a basement is dangerous. If
children or pets will be playing in the area a bolt-on or
child-proof cover is recommended.
The pump can be placed directly on the bottom of a poly
or fiberglass sump basin or a concrete sump bottom. If
the bottom is packed gravel the stones must be larger
than ½" (13mm) in diameter and the pump should be
placed on bricks for support.
After connecting the discharge pipe to the pump it can
be lowered into the sump (basin). Always lower the
