ROD AND FLOAT
SWITCH
INSTALLATION
See Figure 2 for stop positions.
1. Thread
float rod into float until it is firmly hand tight.
2. Slide rod guide
over float rod; follow
it with a rod stop
bushing
(A) set about eight inches
down from the top of
the rod.
3. Slide float rod up through
the eye in the switch
arm. Add
a rod stop bushing
(B) at the top of the rod.
4. Open
large loop
on rod guide and mount
it around
the
column.
Fasten with screw,
making sure that the float rod
hangs vertically
from the switch
and moves freely in the
rod guide. Make sure the rod guide is tightly
clamped.
5. Adjust rod stop bushings
for designed
level control.
6. Lift the rod up and down
to be sure the switch
will click
and that the arm does not bind on the rubber
bushings.
The rod must also move freely in the guide.
7. Fill the sump
and run pump
through
one complete
cycle
to check switch
operation.

Rod Guide
The switch
unit operates
as follows:
1. When the sump is dry, the float rod hangs from the switch
alan. Its weight
holds the switch
off.
2. When the water rises in the sump, the float lifts the svdtch
rod. The buoyancy
will push the switch
arm up and turn
the switch
on.
3. When the water is pumped
out of the sump, the float
drops down again. The weight of the float will allow the
rod and switch arm to lower and turn the drainer switch
off.
DO NOT ALLOW
PUMP TO RUN DRY
Pump should
not be allowed
to run dry prior
to shutting
off.
To do so voids the warranty
and could ruin the pump.
If necessary,
adjust the float so this will not happen.
ELECTRICAL
CONNECTIONS
Risk
of electric
shock.
The
Sump
Pump
has a 3-prong
electric
plug.
The third
prong
is used to
ground
the pump
to prevent
possible
fatal
shock.
The
third
prong
should
never
be removed.
Your electrical
outlet
should
be the 3-prong,
polarized
type
with
an
internal
ground.
Pump must be wired
into a 15 amp GFCI protected
individ-
ual branch
circuit.
DO NOT
USE AN EXTENSION
CORD.
Testing
for Ground
For your safety, check
your outlet for ground
using a Circuit
Analyzer,
(Figure
3). A Circuit Analyzer
will tell you by a pat-
tern of lights if the power,
neutral,
and ground
wires are cor-
rectly connected
to your outlet.
It can also be used to check
other
outlets
in your home.
A Circuit Analyzer
is available
in
the SEARS Electrical
Department.
