and pumping. The pump will start as indicated
in Specifications.
2. Check the turn-off position. The pump will stop
approximately as indicated in Specifications.
3. If the pump does not operate, check the
electrical service.

the Sump Pit by
the Pump Handle.
To Clean the Impeller
Follow the steps shown below. To reassemble pump,
reverse the sequence.
Risk of electric shock . Can shock, burn
or kill. Before removing the pump from the sump for
service, always disconnect the electrical power source
to the pump. Do not raise, lower, or carry pump by
the power cord. Use the handle that is provided on the
pump.
Airlocks
When a pump airlocks, it runs but does not move any
water. An airlock will cause the pump to overheat and
fail. To avoid this problem, drill an 1/8" (3.2 mm) hole in
the discharge pipe just above the pump outlet but below
the check valve. 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.
3. Remove the Screws
that hold the Suction
Housing to the Pump Assembly
and clean out the Impeller.
