4. Remove the two fasteners in the cast iron volute
near the discharge area. Align the hole with the
diaphragm switch and replace the fasteners with-
out over tightening (Figure 3).

Never cut off grounding prong or
use an adapter.
Support pump and piping when
assembling and after installation. Failure to do so
could cause piping to break or pump to fail, which
could result in property damage and/or personal injury.

5. Insert the pump power cord plug directly into the
back of the Solid-State Water Sensor cord plug
(Figure 4).

6. Set pump into sump. Locate the pump on a solid
level surface.
Do not place directly on clay, gravel,
or any loose or sandy surfaces. These surfaces
contain small stones or sand that may clog or damage
the pump, which could result in pump failure causing
fl ooding and property damage.

• Position pump switch away from the inlet so the
switch is clear from incoming water. (See Figure 5)

7. This pump has a 1-1/2" NPT discharge. If exist-
ing piping is 1-1/4" NPT, an adapter bushing (not
included) may be used. Do not use piping that is
less than 1-1/4" NPT. Piping that is too small will
result in reduced output.
8. A check valve is required in the discharge line to
prevent back-flow when the pump shuts off. It is best
to install the check-valve directly to the pump dis-
charge. Thread a check valve into pump discharge.
Be careful not to strip or cross-
thread. Do not use pipe joint sealant.
Flexible discharge hose is intended for
temporary use only. Rigid PVC or metal pipe is required
for a permanent installation. If fl exible discharge hose is
temporarily used, make sure pump is secured in sump
pit to prevent movement. Failure to secure pump could
allow pump movement and cause switch interference
and prevent pump from starting or stopping. This could
result in fl ooding and property damage.
