8. Fully tighten the couplings to the correct torque.
the maximum torque is mentioned in torques (all
pump types). Make sure that the gaps between the
couplings are equally divided on both
sides (see drawing).
9. Attach the coupling guards (681) with the hexagon head
bolts (901.01) to the motor stool (341).
10. Connect the pump to the electrical power and put
the pump into operation according to the safety
precautions. Electrical install.
SECTION: R - Torques:
R-1) Torques (all pump types):
IMPORTANT
The torques given in the table below are
valid for materials at 69ºF, therefore it
is essential that pumps are assembled at
69ºF ambient temperature.
IMPORTANT
Never tighten nuts and bolts to the required
amount of torque at once. Always make sure
to increase torque using at least 3 attempts
before reaching the required amount.
IMPORTANT
Always make sure to tighten nust and bolts
crosswire!
IMPORTANT
The torques given in the tables below already
take into account possible frictional
resistance of windings and materials.
Therefore, never use grease, copper paste or
oil on the nuts and bolts when applying the
torques!
