Safety Symbols
The following safety symbols may be used throughout this manual to alert you to important safety
hazards and precautions
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 haz-
ard exists.
TURN POWER OFF
Live power to a device creates a
potential shock hazard. Turn Off
power to the device and associated
accessories when servicing the unit.
NO SMOKING
Sparks and embers from burning cig-
arettes or pipes can ignite fuels and
their vapors.
NO OPEN FLAMES
Open flames from matches, lighters,
welding torches, etc. can ignite fuels
and their vapors.
NO POWER TOOLS
Sparks from power tools (such as
drills) can ignite fuels and their
vapors.
NO VEHICLES
Moving vehicles in the area during
service can create a potential for per-
sonal injury to you or others. Sparks
from starting vehicles can ignite fuels
and their vapors.
NO PEOPLE IN THE AREA
Unauthorized people in the area dur-
ing service can create a potential for
personal injury to you and them.
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.
WEAR EYE PROTECTION
Fuel spray from residual pressure in
the lines can cause serious eye inju-
ries. Always wear eye protection.
INJURY
Careless or improper handling of
materials can result in bodily injury.
GLOVES
Wear gloves to protect hands from
irritation or injury.
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
Before You Begin

Before You Begin
To protect yourself and your equipment, observe the following warnings and cautions.
WARNING
This product is to be installed in systems operating near locations
where highly combustible fuels or vapors may be present.
Fire or explosion resulting in serious injury or death could result if the
equipment is improperly installed or modified. Serious contamination
of the environment may also occur.
1. Read and follow all instructions in this manual, including all
safety warnings. Install only as described in this manual.
2. To avoid electrical shock, be sure AC power to the monitor is off
during installation.
3. To protect yourself and others from being struck by vehicles,
block off your work area during installation or service.
4. Comply with all applicable codes including: the National
Electrical Code; federal, state, and local codes; and other
applicable safety codes.
5. Do not alter or modify any component or substitute components
in this kit.
6. Substitution of components may impair intrinsic safety. Circuitry
within the sensor and console barrier form an intrinsically safe,
energy-limited system. This system makes the groundwater
sensor intrinsically safe for use in a Class I, Group D hazardous
location. The sensor wiring is intrinsically safe only when
connected to Veeder-Root Consoles.
7. 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.

Sensor Installation
To install the groundwater sensor:
1. Turn off ACpower totheVeeder-Root monitoring system.
2. Removeany existing cap from the well in which the sensor will be installed.(A new well cap is
supplied with the groundwatersensor.)
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].
Figure 2. Groundwater Sensor Installation
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.
Be sure to observe proper polarity between sensor and console [Figure 3].
Figure 3. Groundwater Sensor Field Wiring Diagram
11. Seal wire nuts with epoxy sealant following instructions in Figure 4 on page 7.
CAUTION: Epoxy sealant is irritating 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.
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 is below 50˚F (10˚C), keep resin in a warm place prior to
mixing (e.g., in an inside pocket next to body).
1. Remove guard bag, using caution not to damage inner bag.
2. Grip both edges of bag at the center barrier as shown in the figure to the left
while you flex and wrinkle the bag across the barrier. This will weaken the
barrier.
3. Squeeze the CLEAR SIDE of the resin, forcing the resin through the center
barrier.
4. Mix thoroughly to a uniform color by squeezing contents back and forth 25-30
times.
5. Squeeze resin to one end of bag, and cutoff other end.
6. Slowly insert connection into sealing pack until it fits snugly against the opposite
end.
7. Twist open end of bag and use tie wrap to close it off, or wrap open end of bag
with vinyl electrical tape (not included) and position the taped end up until the
resin jells.
Make sure that the
