Adjust the Functional Element on both packers to maximum
relief pressure by rotating fully clockwise. If maximum pump
pressures are NOT a minimum of 5 psi (34 kPa) below the
Functional Element relief setting then proper check valves
with pressure relief are required to be installed in the
discharge line of each pump to prevent product from being
pumped through the pressure relief system of the adjacent
pump when it is not operating.
The in line check valves and 115 VAC relay are not available from
Red Jacket and should be purchased locally. See figure 2.13.
Ball valves should be installed at the pump end of the discharge
line for ease of maintenance and troubleshooting. See figure 2.12.

When greater flow rates are needed, two pumps may be installed in the same pip-
ing system by means of a manifold. If installed according to the illustration below
(figure 2.12), tandem systems offer backup support so operations can continue if
one pump stops working.
