Follow all rules, codes, and laws that apply to your area and installation.
SAFETY PRECAUTIONS - INSTALLATION AND MAINTENANCE
Always make sure ALL power to the dispenser (motors and electronic head) is turned OFF before you
open the dispenser cabinet for maintenance. Physically lock, restrict access to, or tag the circuit
breakers you turn off when servicing the dispenser. If applicable, be sure to trip (close) and test the
emergency valve(s) under the dispenser BEFORE beginning maintenance.
Make sure that you know how to turn OFF power to the dispenser and submersible pumps in an
emergency. Have all leaks or defects repaired immediately.
EQUIPMENT PRECAUTIONS
Be sure to bleed all air from the product lines of remote dispensers and prime suction pumps before
dispensing product, otherwise, damage to the equipment may occur. Always use the approved
method for lifting the dispenser. Never lift by the nozzle boot, sheet metal, etc., otherwise equipment
damage or personal injury may occur.

DANGER

INDICATORS AND NOTATIONS
Danger indicates a hazard or unsafe practice which, if not avoided, will result in severe injury or
possibly death.
Warning indicates a hazard or unsafe practice which, if not avoided, may result in severe injury
or possibly death.
Caution indicates a hazard or unsafe practice which, if not avoided, may result in minor injury.
Important information to consider, otherwise, improper installation and/or damage to
components may occur.
DEF DISPENSER CONSIDERATIONS
Human Exposure: Avoid contact with eyes, skin, and clothing. Refer to Material Safety Data Sheet
(MSDS) for detailed safety information. In case of contact with eyes, immediately flush with water for
at least 15 minutes, occasionally lifting the upper and lower eyelids. In case of skin contact,
immediately flush skin with plenty of water for at least 15 minutes while removing any contaminated
clothing and shoes. Wash clothing and clean shoes before reuse. In both cases, get medical
attention if symptoms occur.
Temperature: DEF freezes at approximately 12ºF. This dispenser provides no heating for
protecting the DEF on against cold temperatures. While allowing DEF to freeze does not damage
the DEF, it can damage the fluid containing components of the dispenser. This dispenser should not
be used in areas where the ambient temperature will go below 12ºF to prevent the DEF from freezing.
If the DEF in the dispenser is allowed to freeze, components in the dispenser must be inspected for
damage before the dispenser is placed back into service. Additives may not be used in DEF to lower
the DEF freezing point. Prolonged storage above 77ºF can impair the quality of DEF and reduce its
shelf life.
Compatibility: DEF can cause corrosion of components that are made from incompatible materials.
Using incompatible materials can also contaminate the DEF which can potentially damage the
vehicle’s Selective Catalytic Reduction (SCR) system. Use only materials in the installation that are
known to be compatible with DEF.
Prover Cans: Prover cans designed and/or used for motor fuels must not be used for measuring
DEF nor should DEF Provers be used for measuring motor fuels. Contaminating the DEF with motor
fuel can potentially damage the vehicle’s SCR system.
Disposal: During testing and calibration, DEF is dispensed into containers or the prover can. This
DEF must be properly handled to prevent contamination of the DEF (if it is to be reused) and any
potential ground water contamination (if it is to be disposed of). See PEI Recommended Practices for
the Storage and Dispensing of DEF (RP100-10).
Sealant: When making connections on NPT pipes, it is important to use the correct sealant to reduce
the possibility for leaks. Loctite 567 is recommended to be used as a sealant along with Loctite
activator 7649. Apply the activator onto both surfaces and allow it to dry before applying the sealing
compound. Follow the manufacturer’s instructions for use of these materials. Do not use Teflon
tape. Do not use any sealing compound on BSPP fittings. These fittings are provided with an o-ring
which forms the proper seal.
Recommended Practices: Refer to PEI publications RP1100 Recommended Practices for Storage
and Dispensing of Diesel Exhaust Fluid (DEF) for additional information and guidelines for working
with a DEF installation.

2 Site Design & Preparation
2.1 Local, State, and Federal Codes
Select S1 Compact Electronic dispensers are only part of a fuel dispensing system. A fuel
dispensing system typically comprises equipment and safety devices from a variety of
manufacturers. It is the responsibility of the dispenser owner to have a qualified installer
ensure that all of the necessary equipment and accessories are included to meet the
requirements of the application and all tanks (both underground and aboveground), piping
and fittings, check valves, leak detection and corrosion protection devices, wiring, venting
systems, filtration devices, safety valves, submersible pumps, etc. are installed in accordance
with the manufacturer’s instructions and in compliance with local and regional building codes
and requirements pertaining to private fueling facilities (or other locations where the
dispenser may be installed).
These requirements may include references to the National Electrical Code (NFPA 70); Code
for Motor Fuel Dispensing Facilities and Repair Garages (NFPA 30A); Flammable and
Combustible Liquids Code (NFPA 30); Code of Federal Regulations, Title 40, Section 280 (40
CFR 280); United States Environmental Protection Agency (U.S. EPA) Technical Regulations
of 9-23-88 and U.S. EPA Financial Responsibility Regulations of 10-26-1988.
Where local requirements do not specify applicable codes, Wayne recommends using the
codes listed above. These codes are comprehensive and detailed, often requiring
interpretation to cover unusual situations, and, therefore, the associated handbooks (where
applicable) should also be consulted. (The handbooks are also available from the same
sources.)
Due to the variety of locations encountered, further information on installation cannot
be dealt with in this document except as the codes relate directly to the installation of
the dispenser. Therefore, it is strongly recommended that a qualified engineer or
contractor familiar with local regulations and practices be consulted before starting
installation.

2.2 Safety Precautions
NFPA 30A states that:
“When maintenance to Class I dispensing devices becomes necessary and such
maintenance is capable of causing the accidental release or ignition of liquid, the following
precautions shall be taken before such maintenance is begun:
Only persons knowledgeable in performing the required maintenance shall perform the
work.
All electrical power to the dispensing devices, to the pump serving the dispensing
devices, and to all of associated control circuits shall be shut off at the main electrical
disconnect panel.
The emergency shutoff valve at the dispenser, if installed, shall be closed.
All vehicular traffic and unauthorized persons shall be prevented from coming within 20 ft.
(6 m) of the dispensing device.”1
Electric shock hazard! More than one disconnect switch may be required to de-energize the
pump for maintenance and servicing. Use a voltmeter to make sure ALL circuits in the pump
are de-energized. Failure to do so may result in serious injury.
Lockout/Tagout requirements of the U. S. Dept. of Labor, Occupational Safety and Health
Administration (OSHA) may also apply. Refer to Title 29, Part 1910 of the Code of Federal
Regulations (29CFR1910), Control of Hazardous Energy Source (Lockout/Tagout).

2.3 Ethanol and Bio-Diesel Installations
All Wayne dispensers (except DEF models) are rated and Listed for use with Ethanol blends
up to and including E10. For blends that exceed E10, the dispenser must be supplied with a
first suffix option of “9” for blends up to E25 and B20 or an “E” prefix option for blends up to
E85. “E” prefix dispensers are Listed for use up to and including E85 blends. The “9” suffix
is available for all enhanced capacity remote dispensers. The “E” prefix is only available on
remote dispenser model E3/G7107D/R. When considering an installation, all fluid handling
components must be rated for the type of fuel that will be dispensed. Piping connections for
above E10 must use UL Classified Saf-T-Lok Teflon pipe sealant.
Some alternative fuels and additives can degrade the dispenser performance and integrity if the
dispenser is not designed for that product. In addition, converting between fuel types
(especially between an alternative fuel to a standard fuel) can degrade the dispenser
performance and integrity. Before changing fuel types, always make sure that the dispenser is
designed for use with the new product. In addition, the dispenser should be closely monitored
for any sign of degradation or leaks after the conversion. This monitoring should take place in
the days, weeks and even a month after the conversion takes place. Leaks can result related to
the conversion which can create an environmental hazard.
DEF models should only dispense DEF.
2.4 DEF Installations
While DEF is not a combustible liquid, the electrical requirements as well as the proximity of
the DEF dispenser to dispensers that handle combustible liquids could dictate that various
requirements of NFPA codes be followed for a hazardous area. Wayne recommends that
DEF dispensers be installed using the same techniques and requirements that would be
applied to a dispenser dispensing flammable liquids. NPT piping connections for DEF should
use Loctite 567 sealant and Loctite accelerator 7649. Use the accelerator on both sets of
threads and allow it to dry before applying the sealant. Put the sealant on the male threads
only, being careful not to get excess inside the pipe or fittings. Do not use Teflon tape. Do
not apply sealant or Teflon tape to BSP fittings. DEF dispensers using internal DEF filter kit
require additional clearance under the base of the dispenser for the DEF filter. See the “Base
Layout” for details.
DEF models should only dispense DEF.
2.5 Existing Installations
If the dispenser is to be installed on an existing installation, it is still the responsibility of the
installer to read and follow this installation manual in its entirety and make sure the existing
installation meets the requirements and satisfies local, state, and federal codes.

2.6 Island Construction, Dispenser Anchoring, Piping, and Bollards
This dispenser is designed to be shelf-mounted. The base of the dispenser contains four
bolt slots that measure 7/16” x 1-7/16” for anchoring the dispenser to the shelf. Allow for
the proper dispenser containment box if required by local, state, or federal regulations.
Reference Appendix A, Dimensions & Base Layouts, for dispenser and shelf dimensions.
Vertical supply risers and electrical conduits must be located per the Installation Drawing
for the appropriate model. Proper height must be maintained to avoid undue stress on the
dispenser. See Section 3.3 for wiring and conduit requirements. Reference Appendix B
for Wiring Diagrams.
Supply piping should be selected and installed based on the product dispensed and in
accordance with local, state, and federal regulations. The piping manufacturer’s
instructions should be followed for the proper trenching, connection, sealing, corrosion
prevention, pressure relief, leak detection, containment, and testing.
DEF dispensers using the internal DEF filter kit require additional clearance under the
base of the dispenser for the DEF filter. See the base layout for details
This dispenser should only be mounted to a UL Listed tank that already has a suitable
means to mount the dispenser to the tank. No modification to the tank is allowed for the
installation of the dispenser.
Bollards must be installed around the dispenser to prevent
vehicles from coming into contact with the dispenser.
Wayne dispensers are specified to work at a maximum normal operating pressure of 50 PSI.
Normal operation can create pressure spikes which may exceed 50 PSI. These normal
spikes are easily handled by the dispenser. Wayne dispensers are designed and tested to
withstand pressures up to 250 PSI, for short durations, without rupture or permanent
distortion. Certain extreme conditions, such as installations with above-ground tanks and
very long runs of pipe, can create pressure spikes that may damage the dispenser and its
accessories. If these conditions exist, measures must be taken to reduce or dampen these
pressure spikes to prevent damage to the equipment.
To maximize flow, position the remote dispenser and tank as close together as possible
and minimize the number of turns in the piping. Consult the submersible pump
manufacturer for the proper sizing of the submersible pump, any necessary leak
detection equipment, and installation details.
Product piping must avoid the creation of vapor in the lines and deliver a minimum
pressure of 25 psi at the remote dispenser inlet when all dispensers connected to the
same submersible pump are operating. The dispenser’s maximum operating pressure is
50 psi.
A listed, rigidly anchored emergency shutoff valve must be installed, in accordance with the
manufacturer’s instructions. Failure to install the proper emergency shutoff valve will
present a hazardous condition that could result in serious injury and/or environmental
damage.
NOTE: On E85 dispenser models, use shear valve part number 10P-0152E85 manufactured
by OPW.
“Listed” means published on a list by a nationally recognized testing laboratory (NRTL) which is
responsible for product evaluation and is acceptable to the authority having jurisdiction. Underwriters
Laboratories, Inc. is one example of a Nationally Recognized Testing Laboratory. For more information
on NRTL’s, see Title 29, Parts 1907 and 1910 of the Code of Federal Regulations, Safety Testing or
Certification of Certain Workplace Equipment and Materials.

3.3 Electrical Wiring
3.3.1 General
DFS recommends employing a qualified licensed electrician for all wiring.
A primary requirement in dispenser installation wiring is to provide a means for
disconnecting all power connections, including the neutral, as well as the communication
lines to the dispensers for a safe shutdown and servicing of the units. All wiring to the
dispenser must be broken for the Emergency Electrical Disconnect.
A hazardous liquid is being handled, so it is extremely important to ensure that all wiring
and conduit are in accordance with all local, state and federal regulations, including, but
not limited to, the National Electrical Code (NFPA 70), NFPA 30, and NFPA 30A.
NOTE: NFPA 70 requires that all electrical connections to the dispenser be made with
threaded, rigid conduit and properly sealed conductors. All dispensers and electrical
connection boxes must be grounded per NFPA 70.
3.3.2 Electrical Termination Descriptions - All Dispensers
The chart to the right describes the
standard electrical inputs and outputs
utilized in the Wayne Select S1 Series
and can provide assistance in
interpreting the Wiring Diagrams in
Appendix B. These connections are
found on the standard terminal block
located in the head of the dispenser.
3.3.2.1 Control Power (Hot)
The control power (hot) is a 120VAC [international (int’l) - 240VAC] input for supplying power
to the electronic register. The control power must have a dedicated breaker and must remain
on all the time. For sites with multiple dispensers, if it is not practical to use separate
breakers for each dispenser, the number of dispensers that can be included on one breaker
is determined by analyzing the power requirements of each dispenser to determine the total
load required for the group of dispensers. The breaker and wire must be sized accordingly
for that load and the length of the wire run.
NOTE: When the dispenser is connected to a fuel control and/or tank monitoring system, they
should be powered from the same circuit breaker panel so that they share a common
neutral.
3.3.2.2 Control Power (Neutral)
The control power (neutral) is an AC return line from the electronic register to the breaker
panel.
3.3.2.3 Ground
A good ground ensures proper operation of the equipment and provides the necessary safety
factors. A ground wire must be connected between the unit’s ground connection on the
terminal strip and the main electrical service panel. One (1) earth ground connection is
required per unit. Make sure that a ground rod is properly installed and wired to the ground
bus strip of the main electrical service panel in accordance with the National Electrical Code.
Do not rely on electrical conduits as the grounding connection.
