Backflow of water from piping.
Faulty float switch.
Defective float switch.

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.
CORRECTIVE ACTION
If blown, replace with fuse of proper size.
If voltage under recommended minimum, check size of wiring from
main switch on property. If OK, contact power company or hydro authority.
