Attaching the Expansion Relief Vent Line
1. Remove the metal protective shipping caps from the flare fittings (reference Figure 1).
2. Attach the vent line taking care not to cross thread the fittings.
3. Tighten the fittings 1/6 to 1/4 turn beyond hand tight.
Before installing pipe threads apply an adequate amount of fresh, UL classified for pe-
troleum, nonsetting thread sealant.
4. Install the piping to the manifold discharge port. Pipe sealant should be used in this joint.
Installation of a ball valve is recommended on the discharge side of the pump or discharge
of the “Big Flo” leak detector housing if used. This will aid in troubleshooting and line test-
ing.
Line check-valves are not required since the pump has a built in check-valve. However, whenever two pumps are
manifolded together to the same discharge piping, check valves with expansion relief are required and should be
installed in the discharge piping of each pump, as close to the pump manifold as possible.
See instructions “INSTALLING TWO PUMPS FOR TANDEM OPERATION” and Figure 12.
