We recommend to consider
Pipework should slope away from the pump inlet and outlet.
Liquid running back into the pump's exhaust can damage it as much as when it is sucked into the inlet.
Think about vacuum gauge location and measurement range.
Put tappings where you want to monitor pressure and also rate of pressure rise (leak rate quantification).
Fit inlet commissioning screens and/or filters
Fit liquid separators on the pump inlet as necessary
Do not forget to allow adequate maintenance access
