Ensure any user installed in-line valves are in the desired position.
Ensure the circulator's process fluid outlet is connected to the
application's fluid inlet and not the outlet, see Section 3.
Ensure all connections are secure and that the proper sealant/lubricant
for the fitting material is used.
Keep the distance between the circulator and the application as short as
possible.

required, make them at the inlet and outlet of your application, not at
the circulator.
