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.

Float

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.
