Check that the threaded connectors have the correct
torque during commissioning.
We also recommend checking these threaded connec‐
tors for correct torque at least once a year because the
pump material yields and the tightening torque is then
reduced.
1. Tighten all screws (37) to 2.2 Nm.
2. Tighten the screw (11) to 3.4 Nm.
3. Tighten the nut (25) at position I by instinct as there is no
torque specified for this nut.
