Turn the adjustment screw clockwise until the
impeller makes contact with the suction cover.
Tighten it further 1/8 turn, 45

the correct clearance between the impeller and
the suction cover in the next step.
Lock the impeller with a screw driver or similar
(L= min. 200 mm/7.9 inch), see ig. to prevent
rotation of the impeller. Fit the washer and the
greased impeller screw and tighten, torque to 44
Nm (32.5 lbf­ft).
Check that the impeller rotates freely.
When changing an impeller or after service, we
recommend that the screw is irst tightened to
the prescribed torque and then turned an addi­
tional 1/8 ( 45°) of a revolution. The screw will
be loaded to its yield point and the load capacity
of the jonit will be higher.
