Assembly – 4FZ option
The assembly procedure is done in the reverse order to the disassembly.
Nevertheless there are a few things that you have to remember in order to assemble the
pump correctly.

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 a few weeks of operation retighten the screws with appropriate torque.
