The coupling guard and its footboard, if any, have been removed.
1. Loosen the support foot and re-tighten it without transmitting any stresses and
strains.
2. Place the straight edge axially on both coupling halves.
3. Leave the straight edge in this position and turn the coupling by hand.
The coupling is aligned correctly if the distances A and B to the respective shafts
are the same at all points around the circumference.
Observe the permissible radial offset in coupling half alignment (
both during standstill and at operating temperature as well as under inlet
pressure.
4. Check the distance (dimension see general arrangement drawing) between the
two coupling halves around the circumference.
The coupling is correctly aligned if the distance between the two coupling
halves is the same at all points around the circumference.
Observe the permissible axial offset in coupling half alignment (
during standstill and at operating temperature as well as under inlet pressure.
5. If alignment is correct, re-install the coupling guard and its footboard, if any.
Checking the coupling alignment with a laser tool
Coupling alignment may also be checked with a laser tool. Observe the
documentation provided by the manufacturer of the measuring instrument.
5.7 Aligning the pump and motor
After having installed the pump set and connected the piping, check the coupling
alignment and, if required, re-align the pump set (at the motor).

The coupling guard and the footboard for the coupling guard, if any, have been
removed.
1. Check the coupling alignment.
2. Unscrew the hexagon head bolts (1) at the motor and the locknuts (3) at the
baseplate.
