check this, place the pump in a vessel filled
with water, raise the float switch carefully by
hand and then lower it again. As you do so,
note whether the pump switches on and off.

float switch head and the latching holder is
not too small. Proper operation is not guar

When you set the float switch, make sure
that it does not touch the base before the
pump switches off. Caution! Risk of dry-run-
