bearings and require no additional lubrication.
2. The pump should be inspected 3-4 times per year for
pump movement or buildup of debris on the switch or

debris that could interfere with the operation of the
switch.
3. Pedestal sump pump models have open, exposed
motors. Make sure the motor does not get wet.
4. This pump may contain dielectric oil for cooling. This
oil can be harmful to the environment. Check the state
environmental laws before disposing this oil.

high or low voltage, inadequate wiring, incorrect motor
conditions, or a faulty motor or pump.
