2 - Insert the perforated metal sheet coupling guard inside the lantern so that the coupling is accessible from one of the
lateral openings. 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. 15) tighten the assembly with bolts supplied with the unit and
install the supporting foot, when applicable (see fig. 14). When tightening the connecting screws between lantern and
motor make sure not to force the two half-couplings
until they touch each other. If this occurs remove the motor, axially
move the
half-coupling
on the shaft and repeat the fixing procedure.

3 - Applying slight hand pressure to the coupling guard,
rotate it so that one opening of the lantern is
accessible (see fig. 16).
4 - Rotate by hand the coupling through the lateral
opening of the lantern to make sure the pump is
free.
5 - With a proper spacer 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
manufacturer. In the event an adjustment is
necessary, loosen the set screws on the coupling
half and with a screw driver move the coupling half
to attain the gap “S” (see fig. 20). 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.
