2.Mount the float and the float rod stop on the rod.

3.Slide the rod up through the bracket and into the slot in the bottom of the switch housing. Fasten the rod into the switch housing with the pin. See Figure 2.

Make sure the pin holds the float rod in the switch housing; otherwise the pump will not shut off.

NOTICE: Pull gently on the rod to make sure that it cannot come out of the switch housing.

4.Mount the switch assembly on the pump with the screws provided.

5.Run the pump through one complete cycle to verify switch operation is correct and that nothing interferes with the switch’s operation.

Flood hazard. May cause personal injury or prop-

erty damage. Failure to make this operational check can lead to improper operation, premature pump failure and flooding.

AIRLOCKS:

When a pump airlocks, it runs but does not move any water. An airlock will cause the pump to overheat and fail.

This pump has a small hole in the side of the pump housing. See Figure 1. This is an anti-airlock valve. If you suspect an air- lock, insert a hat pin or a pipe cleaner into the anti-airlock hole to clean out the debris.
