Fig. 95: Ring seal unit clamped and marked
5.
Tighten the nuts (Fig. 95).
Tightening the self-locking nuts compresses the
sealing ring against the bar and the connection sleeve
pipe, and establishes a sealed connection. It is
impossible to specify an authoritative tightening
torque value. However, in the process you must make
sure the middle axis of the bar and connection sleeve
are identical. This is the case if the width of the visible
sealing ring around the bus bar is consistent.
Fig. 96: Marking
6.
Mark the bolts with a red paint pen (Fig. 96).
Fig. 97: Protective caps
7.
Put on the plastic caps. This will prevent the
protruding thread of the mushroom head bolts from
damaging the bellows (Fig. 97).
Fig. 98: Hose clamps
8.
Pull the bellows over the connection sleeve pipe
and secure with the hose clamps (Fig. 98).
One small hose clamp encloses the bellows on the
bus bar; two hose clamps on the connection sleeve
pipe. The locks on the two large hose clamps on the
connection sleeve pipe must be positioned offset to
ensure a leak-tight seal (Fig. 94).
The pressure compensation elements also must be
positioned as high as possible.
