6. Fitting
Observe the instructions in section 3, "Safety instructions"!
6.1 General information on fitting
Fitting work must be done with great care by qualified specialist personnel.
As early as during the planning phase it must be ensured that sufficient space is available for installation
and subsequent care and maintenance work.
Adequate lifting equipment must be available before beginning the fitting work.
The tightening torques specified in tabels 4, 5 and 6 must always be adhered to. Any
other tightening torques may result in accelerated wear and damage to the coupling.
Failure to observe the instructions in this section may result in breakage of the
coupling.
Danger to life from flying fragments.
A damaged coupling becomes an explosion hazard. Operating the coupling with
damaged coupling parts is not permitted in potentially explosive environments in
accordance with Directive 2014/34/EU.
Under no circumstances must welding work be done on the coupling or coupling
components, as this will negatively affect the physical property of the coupling.
If coated couplings are used in potentially explosive areas, the requirements made of
the conductivity of the coating and the limitation on the thickness of the coat applied
must be observed in accordance with standard "DIN EN 80079-36".
Where coatings have a thickness < 200 μm, no electrostatic charge is to be expected.
Where coatings are thicker than 200 μm, an electrostatic charge, e.g. by cleaning the
coupling, must be avoided.
At the customer’s express request Flender also supplies unbored or prebored coupling parts for couplings
which will not be operated in potentially explosive environments as set out in Directive 2014/34/EU. The
necessary refinishing must then be carried out in strict compliance with the following specifications and
with particular care!
Responsibility for carrying out the refinishing is borne by the customer. Flender will
accept no guarantee claims arising from unsatisfactory refinishing.
