Safety Warnings
To protect yourself and your equipment, observe the following warnings and important information:
Safety Symbols
The following safety symbols may be used throughout this manual to alert you to important safety hazards and
precautions
WARNING
This product is to be installed and operated in the highly combustible environment of a
gasoline storage tank where flammable liquids and explosive 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. Do not alter or modify any component or substitute components in this kit.
5. Warning! Substitution of components may impair intrinsic safety.
6. Field wiring to the Sensor must not share a conduit with any non-intrinsically safe
device’s wiring.
7. Warning! To prevent ignition of flammable or combustible atmospheres, disconnect
power before servicing.
8. 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.
9. 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.
10. A groundwater sensor should be installed only in wet wells where preliminary testing
has determined that water in the well is not contaminated, or contaminated water has
been remediated and is now clean.
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 haz-
ard. Turn Off power to the device and associated
accessories when servicing the unit.

Sensor Installation
1. Turn off AC power to the Veeder-Root monitoring system.
2. Remove any existing cap from the well in which the sensor will be installed. (A new well cap is supplied with
the groundwater sensor.)
3. Lower the groundwater sensor into the monitoring well until the water float touches the bottom of the well.
4. Raise the sensor 2-inches to 4-inches from the bottom of the well and mark the sensor with a piece of tape at
the point even with the top of the well casing.
5. Secure the sensor at the point marked with the tape to the retainer under the sensor well cap. Allow any
excess sensor length (should be no more than 2-feet) to hang loosely from the retainer [Figure 2].

6. Press the sensor well cap into the top of the well with the excess sensor length hanging inside the well
housing.
7. Press down the locking handle on the sensor well cap to secure it in position and to form a water-tight seal
between the sensor well cap and the monitoring well housing.
8. Pass the end of the sensor cable through the nut, bushing, and cord grip fitting and into the Junction box (J-
box). Pull the excess cable through the fitting and out the opened side of the J-box.
9. After sliding the J-box cord grip fitting up to the J-box, apply the UL-classified sealant (suitable for use with the
fuel involved) to the fitting then screw it into the J-box. Tighten the J-box cord grip fitting nut to ensure a
watertight seal at the sensor cable entry.
10. Using the wiring nuts, connect the wires from the sensor cable to the field wires from the console (see
General Product Wiring Diagram on page 2). Be sure to observe proper polarity between sensor and console.
11. Seal wire nuts with epoxy sealant following instructions in Figure 3.
12. For additional security, a padlock may be installed on the sensor cap to ensure that the locking handle cannot
be opened by unauthorized personnel.

Instructions:
NOTE: When temperature isbelow 50°F (10°C), keep
resin in awarm place prior to mixing (e.g., in an
inside pocket next to body).
1. Open epoxy sealant package, and remove resin pak.
2. Holding resin pak as shown in A, bend pak along
long length.
3. Asshown in B, firmly squeeze the RED SIDE of the
resin, forcing it through the center seal and into
BLACK SIDE.
4. Mix thoroughly to auniform color by squeezing
contentsback and forth 25-30 times.
5. Squeeze mixed, warm resin into one end of bag and
cutoff other end.
6. Slowly insert wiring connectionsinto sealing pack
until they fit snugly against the opposite end as
shown in C.
7. Twist open end of bag and use tie wrap to close it off
and position the tie wrapped end up until the resin
jells.
CAUTION: Epoxy sealant isirritating to eyes, respiratory system,
and skin. Can cause allergic skin reaction. Contains: epoxy resin
and Cycloaliphatic epoxycarboxylate.
Precautions:Wear suitable protective clothing, gloves, eye, and
face protection. Use only in well ventilated areas. Wash
thoroughly before eating, drinking, or smoking.
