Fitting of assemblybalanced couplings
Observe the safety instructions in section 6.1, "General information on fitting"!
On couplings which have been assemblybalanced each individual coupling component must be marked
on the outside circumference of the screwon flanges with a multidigit number (see marking "XXXXX"
in figure 24). When assembling, care must be taken that only coupling parts having the same numbers on
the outside circumference of the flange are bolted together.
NOTICE
Damage to the coupling
Risk of damage to the coupling through incorrect assembly.
After correct fitting the identical numbers of the parts must be arranged in line and be legible from one
direction (see marking "XXXXX" in figure 24).
