Introduction
This manual contains instructions for installing the components for Veeder-Root Digital Pressurized Line Leak
Detection (DPLLD). The DPLLD equipment performs 3.0 gph line leak tests following each dispense. Depending
on the software enhancement module installed, the DPLLD equipment will also allow, with certain pump types, 0.2
and/or 0.1 gph line tests at full pump pressure. The DPLLD equipment executes leak tests automatically to
eliminate the need for separate annual line leak testing.
1. The DPLLD, Digital Pressure Line Leak Detector, Form Number 8590, is Intrinsically Safe when
installed according to Control Drawing Number 331940-008.
2. The TLS-450PLUS/TLS-450 console/DPLLD sensors are not supported by the Red Jacket Variable
Speed Flow Controller (VSFC). The VSFC is designed for use with PLLD sensors/TLS-350
consoles only!
3. You must consult the Veeder-Root Line Leak Detection Systems Application Guide (P/N 577013-
465) for all information relating to DPLLD applicable pipe types, equipment requirements,
installation kits, and pump compatibilities.
4. A Sump Sensor is recommended for sites with line leak in the event the pump develops a leak.
Line leak will only detect a leak in the line, not in the pump.

Site Considerations
Manholes
When using a SwiftCheck Valve, the manhole must provide at least 8 inches of clearance above the pump head to
install the DPLLD components.
Unused Piping Runs
Where piping runs have been installed for future use, but are connected to the active piping system, isolate the
inactive lines from the active lines using a shutoff valve. Failure to do so may harm system performance.
Existing Check Valves
You must ensure that there are no existing check valves already installed in the pipeline. The presence of any check
valve (other than the one used with the DPLLD equipment) can prevent the DPLLD equipment from detecting line
leaks in the area of pipeline downstream from the check valve.
Manifolded Product Lines
Follow these guidelines as you install a DPLLD equipment into multiple manifolded tanks:
• 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.
• An I/O Module in the console is required to control the pump on the higher-numbered tank and pump control
output for the primary tank, and the “Pump In” (Dispenser ON) signal for the set.
• A DPLLD transducer is only required in the master pump.
• Remove any other check valve or leak detect device in the line that is not shown.
• Refer to the Line Leak Application Guide for check valve requirements.

DPLLD Transducer Installation
This section discusses DPLLD transducer installation for the following DPLLD approved pumps:
• Red Jacket Standard and Quantum pumps - DPLLD transducer/SwiftCheck valve (page 8)
• Red Jacket Standard and Quantum pumps - DPLLD transducer/Pressurstat (page 12)
• Red Jacket Quantum with SpikeCheck Valve (page 13)
• The Red Jacket (page 14)
• Red Jacket Maxxum Big-Flo (page 15)
• FE-Petro (page 16)
Red Jacket Standard and Quantum Pumps (DPLLD w/SwiftCheck)
Use this installation procedure to install a DPLLD transducer with a SwiftCheck valve in a Red Jacket Standard or
Quantum pump.
Disconnect, lock out, and tag all AC power to the TLS console, dispens-
ers and submersible pumps.
When servicing equipment, use non-sparking tools and use caution when removing or in-
stalling equipment to avoid generating a spark.
1. If a ball valve is installed down line from the pump, close it.
2. Do one of the following:
a. If the submersible turbine pump is equipped with a mechanical LLD, remove the mechanical unit and any
related tubing and fittings, or
b. If the submersible turbine pump is not equipped with a mechanical LLD, remove the 2-inch mechanical
LLD port plug.
3. Ensure that the sealing surface for the SwiftCheck valve’s external o-ring is smooth and free from corrosion,
pitting, and any material build-up [Figure 3].
Failure to ensure a smooth seal surface can result in false line leak alarms.

4. Lubricate the external o-ring on the SwiftCheck valve using mineral oil or other suitable lubricant.
5. If there is a Stage II vapor recovery device installed, go to Step 7. If there is no Stage II vapor recovery, install
the SwiftCheck valve [Figure 4] in the mechanical LLD pump port. Thread the DPLLD transducer into the
SwiftCheck Valve.
Do not overtighten the SwiftCheck valve when installing it into the pump. Over tighten-
ing the valve can cause a flow restriction in the line!
Seal the NPT threads only with a UL-Classified, nontoxic pipe sealant suitable for the
fuel involved (for high-alcohol fuel blend applications, Loctite 564 is recommended).
Apply sealant in a manner that prevents it from entering and contaminating hydraulic
cavities.

6. If there is a Stage II vapor recovery device installed in the pressurized piping you must install the SwiftCheck
valve into a Red Jacket leak detector fitting (P/N 038-072) as shown in Figure 5 instead of in the pump’s leak
detector port. Because the DPLLD transducer must be installed downstream from these devices, a monitored
containment sump is required.
There must not be a check valve installed between the SwiftCheck valve and the pump
for DPLLD to function properly.
Ensure that the Healy pump is wired according to the manufacturer’s instructions and utilizes isolation relays.
Lubricate the external o-ring on the SwiftCheck valve using mineral oil or other suitable lubricant and thread
the valve into the Red Jacket fitting.
Figure 5. DPLLD Install W/Healy Mini-Jet System (Required Dielectric Union And Shutoff Valve Not Shown)
7. Thread the DPLLD transducer into the SwiftCheck valve (ref. Figure 4 or Figure 5 as appropriate).
Seal the NPT threads only with a UL-Classified, nontoxic pipe sealant suitable for the fuel in-
volved (for high-alcohol fuel blend applications, Loctite 564 is recommended). Apply sealant
in a manner that prevents it from entering and contaminating hydraulic cavities.
8. Get a watertight cord grip from the transducer installation kit and coat its 1/2” NPT threaded end with UL-
Classified, nontoxic pipe sealant suitable for the fuel involved. Screw the cord grip into one of the openings in
the weatherproof junction box. Feed the end of the DPLLD transducer cable through the cord grip and then
tighten the nut to ensure a watertight seal. Connect and seal the pressure transducer wires to the wires from
the TLS console as described in ‘Epoxy Sealing DPLLD Transducer Field Wiring Connections’ on page 20.
9. The DPLLD SwiftCheck valve eliminates the need for the pump’s Pressurstat or functional element relief valve
so it must be modified as part of the DPLLD equipment installation. Remove the six 1/4-28 slot-head screws
from the Pressurstat or functional element [Figure 6].
10. Remove the spring, piston and diaphragm.
11. Carefully reassemble the Pressurstat or functional element using a new diaphragm suitable for the fuel
involved. Be sure that all mating surfaces are free from debris when reinstalling.

Since the DPLLD transducer replaces the existing mechanical device, it is suitable in applications where there is
no sump.
Disconnect, lock out, and tag all AC power to the TLS console, dispens-
ers and submersible pumps.
When servicing equipment, use non-sparking tools and use caution when removing or
installing equipment to avoid generating a spark.
1. If a ball valve is installed down line from the pump, close it.
2. If the pump does not have a Stage II vapor recovery device installed in the pressurized piping, remove the 2’’
NPT plug from line leak detector port. Install the DPLLD transducer into the 2’’ NPT port (see Figure 9).
Seal the NPT threads only with a UL-Classified, nontoxic pipe sealant suitable for the
fuel involved (for high-alcohol fuel blend applications, Loctite 564 is recommended).
Apply sealant in a manner that prevents it from entering and contaminating hydraulic
cavities.

3. If the pump does have a Stage II vapor recovery device installed in the pressurized piping, lubricate the
external o-ring on the SwiftCheck valve using mineral oil or other suitable lubricant and thread the valve into
the Red Jacket leak detector fitting (P/N 038-072) as shown in Figure 5 on page 10 instead of in the pump’s
leak detector port. Next thread the DPLLD transducer into the SwiftCheck valve.

Seal the NPT threads only with a UL-Classified, nontoxic pipe sealant suitable for the
fuel involved (for high-alcohol fuel blend applications, Loctite 564 is recommended).
Apply sealant in a manner that prevents it from entering and contaminating hydraulic
cavities.
Because the DPLLD transducer must be installed downstream from these devices, a monitored containment
sump is required.
There must not be a check valve installed between the SwiftCheck valve and the pump
for DPLLD to function properly.
Ensure that the Healy pump is wired according to the manufacturer’s instructions and utilizes isolation relays.
4. Get a watertight cord grip from the transducer installation kit and coat its 1/2” NPT threaded end with UL-
Classified, nontoxic pipe sealant suitable for the fuel involved. Screw the cord grip into one of the openings in
the weatherproof junction box. Feed the end of the DPLLD transducer cable through the cord grip and then
tighten the nut to ensure a watertight seal. Connect and seal the pressure transducer wires to the wires from
the TLS console as described in ‘Epoxy Sealing DPLLD Transducer Field Wiring Connections’ on page 20.
5. Open the ball valve down line from the pump.
Red Jacket Maxxum Big-Flo
Disconnect, lock out, and tag all AC power to the TLS console, dispens-
ers and submersible pumps.
When servicing equipment, use non-sparking tools and use caution when removing or
installing equipment to avoid generating a spark.
1. If a ball valve is installed down line from the pump, close it.
2. If any in-line check valves or Big-Flo Diaphragm Valve are installed in the line, they must be removed.
3. Remove the cap from the 2-inch Transducer port next to the 3-inch discharge port. Thread the DPLLD
transducer into the transducer port (see Figure 10).
Seal the NPT threads only with a UL-Classified, nontoxic pipe sealant suitable for the
fuel involved (for high-alcohol fuel blend applications, Loctite 564 is recommended).
Apply sealant in a manner that prevents it from entering and contaminating hydraulic
cavities.
