Safety Warnings
To protect yourself and your equipment, observe the following warnings and important information:
Failure to install this product in accordance with its instructions and warnings will result in voiding of all
warranties with this product.
WARNING
This product is to be installed in systems operating near locations where highly combustible
fuels or vapors may be present.
FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS AND SAFETY PRECAUTIONS
COULD CAUSE DAMAGE TO PROPERTY, ENVIRONMENT, RESULTING IN SERIOUS INJURY OR
DEATH.
1. Read and follow all instructions in this manual, including all safety warnings to protect
yourself and others from serious injury, explosion, or electrical shock.
2. Comply with all applicable codes including: the National Electrical Code; federal, state, and
local codes; and other applicable safety codes.
3. To protect yourself and others from being struck by vehicles, block off your work area
during installation or service.
4. Turn off, tag, and lockout power to the STP before connecting or servicing wiring to the
STP.
5. Do not alter or modify any component or substitute components in this kit.
6. Warning! Substitution of components may impair intrinsic safety.
7. Field wiring to the Sensor must not share a conduit with any non-intrinsically safe device’s
wiring.
8. Warning! To prevent ignition of flammable or combustible atmospheres, disconnect power
before servicing.
9. Before installing or taking the unit into a hazardous area, earth the unit in a safe area to
remove any static charge. Then immediately transport the unit to the installation site. Do
not rub or clean the unit prior to installation. Cleaning is not required under normal service
conditions. Do not rub or clean the unit after installation. If the unit is not fixed to a known
earth point when installed, ensure that a separate earth connection is made to prevent the
potential of a static discharge. When fitting or removing the unit, use of anti-static footwear
or clothing is required.
10. Materials used in the construction of this device do not contain, by mass, more than 10% in
total of aluminum, magnesium, zirconium and titanium or 7.5% in total of magnesium,
titanium and zirconium.

Introduction Safety Symbols

Safety Symbols
The following safety symbols are used throughout this manual to alert you to important safety hazards and
precautions.
Before You Begin
Prior to backfilling the tank top (i.e. covering the lines, UDC, etc.) the contractor is strongly advised to test all of
the secondary containments for leaks, and to monitor the vacuum during the backfill process. Any leakage
detected must be repaired to prevent future vacuum system alarms.
CAUTION: Do not exceed equipment manufacturer’s recommended vacuum levels!
While it is common practice to use an independent vacuum source to provide the initial vacuum, you must ensure
that pump lubricating oil and any other foreign substance is not introduced into the Secondary Containment
Vacuum Sensor (SCVS) system. Failure to do so may damage the SCVS system and will void warranty.
Hardware Requirements
• TLS-350/350R with version 24C or later software
• For proper STP operation, an in-tank Mag Probe is required for TLS Systems without electronic Line Leak
(PLLD or WPLLD).
• At least one Smart Sensor with Pressure Sensor Module
• Line leak (PLLD or WPLLD), or w/o line leak, a Pump Sense and a 4-Relay module is required for STP control
EXPLOSIVE
Fuels and their vapors are extremely explosive if
ignited.
FLAMMABLE
Fuels and their vapors are extremely flammable.
ELECTRICITY
High voltage exists in, and is supplied to, the
device. A potential shock hazard exists.
TURN POWER OFF
Live power to a device creates a potential shock
hazard. Turn Off power to the device and associ-
ated accessories when servicing the unit.
WARNING
Heed the adjacent instructions to avoid equipment
damage or personal injury.
INJURY
Careless or improper handling of materials can
result in bodily injury.
WEAR EYE PROTECTION
Wear eye protection when working with pressur-
ized fuel lines or epoxy sealant to avoid possible
eye injury.
GLOVES
Wear gloves to protect hands from irritation or
injury.
USE SAFETY BARRICADES
Unauthorized people or vehicles in the work area are
dangerous. Always use safety cones or barricades,
safety tape, and your vehicle to block the work area.
READ ALL RELATED MANUALS
Knowledge of all related procedures before you
begin work is important. Read and understand all
manuals thoroughly. If you do not understand a
procedure, ask someone who does.

Introduction Available Kits
4
• STP siphon port with Siphon Check Valve (V-R P/N 188-241-5) installed. An external Siphon Check Valve (V-R
P/N 188-241-5) must be used when making a vacuum source connection between the SCVS system sensors
and the siphon port cartridge for the following STPs including Red Jacket Standard, Red Jacket Quantum and
FE pumps.
NOTE: Only V-R supplied vacuum hose (V-R P/N 332310-001, -002, -003) is approved for use with the SCVS
system).
• Schrader Fitting 576008-672 (optional for North American installations; not required for EU - fitting is included)
• Siphon manifolded tank requirements:
- The Red Jacket STP requires a secondary siphon assembly (V-R P/N 410151-001).
- The Quantum STP comes with two siphons as standard equipment - no additional parts are required.
- FE pumps require a secondary siphon kit (FE P/N 402-507-930).

• 1, 2, 3 or 4 Vac Sensor kits w/o tank float for EU installations (ATEX approved)
Individual kits (requires Vac Sensor/Vac Float field assembly)
Note: For best and fastest installation, purchase of pre-assembled kits is recommended.
• Mounting kit - 1 required per containment sump
• Secondary piping vacuum monitoring kit - 1each required for product line, vapor recovery line, or containment
sump interstice monitoring - includes mounting hardware, tubing/connections, and cables
• Interstitial sensor kit for steel tank - includes Vac Sensor, mounting hardware, tubing/connections, riser cap, 3-
way valve and cables
• 4’, 6’, 8’, or 10’ diameter fiberglass tank Interstitial sensor kit - includes Vac Sensor, mounting hardware, tubing/
connections, riser cap, relief valve, 3-way valve and cables. NOTE: you do not need to order an additional relief
valve for a fiberglass tank installation.

Installation
Overview
A simplified Veeder-Root vacuum sensor installation in an STP containment sump is shown in Figure 1. Vac Sensor
(VS) and Vac Float (VF) modules are assembled in a housing which is shown in Figure 2. A separate mounting
bracket (see Figure 2) is easily attached to the STP riser to support the Vac Sensor housing. Approximately 12
inches (304.8mm) of clearance is required below the pump manifold for the Vac Sensor components. Final
vacuum connections are made once the housing and bracket are in place. A 1/4” NPT port into the interstitial
space of the double-wall vapor return line, double-wall product line, and/or double-wall containment sump must be
accessible in the containment sump. For installations requiring tank interstice monitoring, a riser must be in the
same containment sump for the tank interstitial sensor. Field wiring connections of the Vac Sensor components
are sealed in a customer supplied containment sump junction box (JB).

CAUTION! Use only the materials specified in this manual during installation. Use of any other
materials or lubricants may damage the SCVS system and will void warranty. Lubricate fittings only
with soapy water - do not use any other materials.
