7. Remove the Pump Housing Lid with the O-
Ring. Remove the Impeller. Inspect the wet
area of the pump head carefully. In case of
material damage, also replace the pump
casing.
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.
8. Replace the Impeller. If necessary, remove
the existing O-Ring and press the new O-Ring
into the Pump Casing Lid.
Use always the specified O-Ring type. If
necessary, consult the Levitronix Technical
Service Department. Do NOT twist or roll the
O-Ring and avoid to adding scratches or
particles as this may cause leaking to occur.
9. Assemble the new O-Ring to the Pump Casing
Lid and make sure that it is properly aligned to
the lid nut and is not twisted.
10. Press the Pump Casing Lid with the O-Ring
flush into the Pump Casing Bottom. Apply
uniform pressure and avoid any asymmetric
action (like tilting), which might hurt the O-
Ring.
Not aligned and
twisted O-ring!
