2.1 Pump Head
Remove the front cover and make sure that no particles are trapped inside the rotor housing. Check that the rotor bolts have been
securely tightened, if design provides such an option. If possible, make sure pump turns freely. Put back cover, making sure o-ring
remains in place, and securely tighten the four front cover nuts.
2.2 Direction of Flow
The pump is designed to operate in both directions without modifications. Make sure that the proper direction of rotation applies.
