6.10.3 Test run of fitted coupling parts with dummy flange
Observe the safety instructions in section 6.1, "General information on fitting"!
Before starting fitting work the contact surfaces of the dummy flange and the fitted coupling parts must be
carefully cleaned and all preservative agent must be removed. Specifications relating to pulling-on action
can be found on the orderspecific drawing of the coupling.
CAUTION
Risk of corrosion burns through chemical substances
Avoid burns when working with corrosive cleaning agents.
Observe manufacturer’s instructions for handling cleaning agents and solvents.
Wear suitable personal protective equipment (gloves, safety glasses).
Using the flange screw connection, fit dummy flange, if included in the scope of delivery, onto the fitted
coupling part (e.g. "B" module, "X" module or "M"hub, see figure 41). The dummy flange must be bolted
on so that the identical numbers showing which parts belong with which can be read from one
direction (see mark "AAA" in figure 41). This marking is optional. The mark is dispensed with, if only one
dummy flange has been ordered for two or more identically constructed couplings.
Tighten the screw connection of the flange gradually one after the other to the prescribed tightening torque
(for tightening torque, see orderspecific drawing of the coupling).
WARNING
Risk of serious injury through flying fragments
Risk of serious injury through flying fragments and/or risk of damage to the coupling.
– Locking nuts must only be used three times, to guarantee the locking properties.
– Adhere to specified tightening torques. Observe the instructions relating to cleaning and/or treatment
of the bolts with auxiliary materials.
