Before start-up of the coupling, please inspect the tightening of the setscrews in the hubs, the alignment and the
distance dimension E and adjust, if necessary, and also inspect all screw connections for the tightening torques
specified.
Finally the coupling protection against accidental contact must be fitted. It is required in accordance with
DIN EN ISO 12100 (Safety of Machinery) and must protect against
access with the little finger
falling down of solid foreign objects.
The cover may provide for openings intended for necessary heat dissipation. These openings have to comply with
DIN EN ISO 13857.
The cover must be electrically conductive and included in the equipotential bonding. Bellhousings (magnesium
share below 7.5 %) made of aluminium and damping rings (NBR) can be used as connecting element between
pump and electric motor. The cover may only be taken off with standstill of the unit.
During operation of the coupling, please pay attention to
different operating noise
vibrations occurring.
!
If you note any irregularities with the coupling during operation, the drive unit must be
switched off immediately. The cause of the breakdown must be specified by means of the
table „Breakdowns“ and, if possible, be eliminated according to the proposals. The potential
breakdowns specified can be hints only. To find out the cause all operating factors and
machine components must be considered.
The below-mentioned failures may result in a use of the

coupling other than intended. In
addition to the specifications given in these operating/assembly instructions make sure to avoid such failures.
The errors listed can only be clues to search for the failures. When searching for the failure the adjacent
components must generally be considered.
General failures with use other than intended:
Important data for the coupling selection were not forwarded.
The calculation of the shaft-hub-connection was not considered.
Coupling components with damage occurred during transport are assembled.
If the heated hubs are assembled, the permissible temperature is exceeded.
The clearance of the components to be assembled is not coordinated with one another.
Tightening torques have been fallen below/exceeded.
Components are mixed up by mistake/assembled incorrectly.
A wrong or no pin/elastomer ring is inserted in the coupling.
No original
KTR
components (purchased parts) are used.
Old/already worn out elastomer rings or elastomer rings stored for too long are used.
Maintenance intervals are not observed.
