Action
Always install the sealing with a mounting tool spe-
cified by ABB.
Never hammer directly on the sealing as this may
result in leakage.
Note
A new sealing has an initial wear that can cause lubricant to seep out and in
some cases produce minor residues of rubber particles.
This is normal behavior of the sealing and does not indicate a seal problem. Wipe
the surrounding surfaces after initial run time.
Action
Check the flange surfaces. They must be even and free from pores.
It is easy to check flatness using a gauge on the fastened joint (without sealing com-
pound).
If the flange surfaces are defective, the parts may not be used because leakage could
occur.
Clean the surfaces properly in accordance with the recommendations of ABB.
Distribute the sealing compound evenly over the surface.
Tighten the screws evenly when fastening the flange joint.
Action
Ensure that the correct o-ring size is used.
Check the o-ring for surface defects, burrs,
shape accuracy, or deformation.
Check the o-ring grooves and mating surfaces.
They should be free of pores, contamination
and obvious scratches/damage.
Lubricate the o-ring with grease.
Tighten the screws evenly while assembling.
Check that the o-ring is not squashed outside
the o-ring groove.

for the cassette sealing, in the

Note
Defective o-rings, including damaged
or deformed o-rings, may not be used.
