The following warnings and cautions should be
read carefully before starting the replacement of
the impeller.
The impeller could splash TOXIC or CORROSIVE
CHEMICALS because of the strong magnetic forces.
Flush the pump housing before opening it.
HARMFUL CHEMICALS may be present.
Skin contact and toxic gases may be hazardous to
your health. Wear safety gloves and other appropriate
safety equipment.
The rotating impeller could cause injury. Do not run
the pump system when opening the pump head.
Pay attention to the magnetic forces when handling
the impeller. The attraction of magnetic parts and
particles should be avoided in order to keep the
impeller and the pump head clean and free of
contamination. Avoid magnetic and metal parts within
a radius of about 1 meter.
