The orientation of the ball valves in the inlet and
outlet valve housings is critical. Install the parts of
the ball valve exactly as instructed and refer to Fig.
16. If installed incorrectly, the pump will not operate.
25. Place the inlet valve housing (6) on a flat surface
with the ball valve openings facing up. Lubricate
the seals (15*) and set them into each side of the
inlet valve housing.

valve housing.
WARNING
COMPONENT RUPTURE HAZARD
The relief valve seat (22) must be in-
stalled at the fluid inlet, to reduce the
risk of pump overpressurization. It can-
not relieve pressure if installed in anoth-
er location.
27. Press the seat (22) with the pressure relief valve
into the fluid inlet side of the inlet manifold (1).
This seat is not reversible. Orient as shown in the
detail in Fig. 16. Press the other seat (17), with the
unworn side facing out, into the other side of the
inlet manifold.
NOTE: The pressure relief seat kit (22) includes two
seals (15) and two o-rings (16). When installing a new
pressure relief seat, also install the seals and o-rings
on both sides of the fluid inlet manifold (1).
