3.6.3. Test run
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 two weeks of operation retighten the nuts with appropriate torque.
3.7. Casing emptying procedure
If you experienced hose rapture, take health and safety precautions appropriate to the pumped
liquid. Be prepared to pick up the leaked medium that fills the pump housing.
Make sure that suction and discharge valves are closed before draining.

Unscrew the plug [33] and empty the pump form the
leaked medium.
NOTE! If the pump is casing equipped any sensor
instead of plug, unscrew the sensor to drain the pump.
NOTE! If the pump is oriented with the connections
facing upwards, you can initiate drainage by
unscrewing a few front cover bolts [141] located at the
bottom of the casing [11] and then pulling the front
cover [12].
