- Place the electric motor on the baseplate and bring the two coupling halves
together with approx. 2mm gap between them keeping the motor axially aligned
with the pump shaft. In the event the two shaft heights do not align, proper shim-
ming under the pump or motor feet will be required. Mark the motor and/or pump
anchoring bolt holes. Remove motor and/or pump, drill and tap the holes, clean
and mount pump and/or motor in place and lightly tighten the bolts (see fig. 11).

- With a straight edge ruler check the parallelism of the two coupling halves at
several points, 90° from each other (see fig. 13).
NOTE: Easier and more accurate readings can be attained with instruments such
as Dial Indicators (if readily available).
If the maximum
value of “X” is
higher than that
listed in the table
2 (for the given
coupling size) it
will be required to
correct the align-
ment by using shims under the pump or motor feet. When the measured values
fall within the tolerances (tolerances only given for “S”), the pump and motor
mounting bolts can be tightened.

- Inser t the per forated metal sheet coupling
guard inside the lantern so that the coupling
is accessible from one of the lateral open-
ings. Couple the electric motor to the pump
lantern engaging the two coupling halves,
hands may reach the coupling halves through
the lateral opening (see fig. 7) tighten the
assembly with bolts supplied with the unit
and install the suppor ting foot, when applica-
ble (see fig. 6).
3
- Applying slight hand pressure to the cou-
pling guard, rotate it so that one opening of
the lantern is accessible (see fig. 8).
4
- Rotate by hand the coupling through the lateral opening of the lantern to make
sure the pump is free.
5
- With a feeler gauge, check the distance between the two coupling halves. The
gap value “S” should be as listed on table 2 or as given by the coupling manu-
facturer. In the event, an adjustment is necessar y, loosen the set screws on the
coupling half and with a screw driver move the coupling half to attain the gap “S”
(see fig. 12). Then tighten the set screw and rotate the rotor by hand to make
sure, once more, that there is no obstruction.
6
- Rotate back the coupling guard by hand through the two openings of the lantern
so that both openings are completely covered. This will complete the alignment
verification of the MONOBLOCK design.
7
- Remove the coupling guard and its extension (if there is one) attached to the
pump, by removing the two locking screws (see fig. 9 and 10).
