Figure 4-15. Manifolded Product Lines WPLLD Installation - Dual Pumps, Single Tank
MULTIPLE TANKS WITH MANIFOLDED PRODUCT LINES
Version 12/112 or later software provides a feature that permits the use of WPLLD on product lines supplied by multiple
tanks with submersible pumps, up to a combined maximum of eight tanks and pumps. Please refer to the Setup Manual
for detailed instructions when selecting this option.
Follow these guidelines as you install a manifolded WPLLD system with multiple tanks:
•
A non-vented SwiftCheck valve must be installed in the
secondary
pump(s).
•
Dielectric unions and flexible piping elements should be used as required by federal, state, and local requirements for
the specific piping application. Location of unions may vary with configuration.
•
A relay must be available on either a Four Relay Module or I/O Combination Module to control the pump on the
higher-numbered tank. The WPLLD Module will provide pump control output for the primary tank and the “Pump
In”
(Dispenser ON) signal for the set.
WPLLD System Installation Procedure
1. Install the Non-Vented valve in the mechanical LLD port of the
secondary
pump [Figure
If the manifolded set has more than one
secondary
tank, install a Non-Vented valve in each of the additional
secondary
pumps
the same way.
IMPORTANT! Seal any NPT threads using a UL-classified, non-toxic thread sealant suitable for the fuel involved.
