9. Holding the float out sideways, hook the float rod on to
the switch arm and swing the float rod down.
10. Insert the float rod in the hole in the tether strap.
11. Reinstall the pump in the sump, check all piping connec-
tions, and reconnect the power. Run the pump through
one complete operating cycle to check for proper opera-
tion. Failure to make this operational check may lead to
flooding and will void the warranty.
AIRLOCKS
When a pump airlocks, it runs but does not move any water.
An airlock will cause the pump to overheat and fail. These
pumps have a built in anti-airlock hole. See the exploded
view on the repair parts page for the location of the hole.
Leakage from the anti-airlock hole is normal.
If you suspect an airlock, unplug the pump, clean out the
anti-airlock hole with a paper clip or a piece of wire, and
restart the pump.
