When fastening the screws, remember to do it
according to the tightening procedure and with the
appropriate torque.
NOTE! After a few weeks of operation retighten the
screws with the appropriate torque.
We recommend you to conduct a test run of the pump before installing it in the system, so
no liquid gets wasted if the pump leaks or perhaps does not start accordingly to wrong
assembly of the pump.
After a few weeks of operation retighten the screws with appropriate torque.
