WARNING: All covers must be returned to their designated locations, or the dispenser will
be unsafe to operate, and the warranty will be voided.
WARNING: Do not cross-phase dispensers which are activating the same submersible pump.
Cross-phasing magnifies the voltage on the submersible pump relay, will damage
the relay, and potentially the submersible pump.
WARNING: Failure to properly ground the equipment can cause injury or damage to the
equipment and will void the Bennett Limited Warranty.
WARNING: Do not use conduit as a ground. Do not use wire nuts on ground wires. Use only
compression connectors on ground wires.
WARNING: Submersible pump relay wires may be “hot” in the dispenser when the signal wire
is energized from another dispenser. Switch OFF the breakers to all dispensers
sharing pump relays when performing maintenance
WARNING: Failure to anchor the dispenser to the island will void the warranty and may cause
injury to personnel, damage to equipment, or death.
WARNING: The electrical terminal sequence does not necessarily correspond to the sequence
of the hydraulic product lines in the hydraulics cabinet.
WARNING: To prevent electric shock and static discharge onto the sensitive electrical
components, frequently ground yourself and use static grounding straps when
possible.
WARNING: The impact safety valve (also called the shear valve, fire valve, or emergency
valve) must be closed when performing servicing, installation, or maintenance on
this equipment.
CAUTION: Lift straps must be equal length and parallel to each other to prevent damage to
the cabinet towers (see Figure 1).
CAUTION: Transport the dispenser on the shipping pallet as close as possible to the final
destination.
CAUTION: Do not splice or “daisy chain” communication data wires. Damage to the control
console may result.
CAUTION: Use only UL listed threaded rigid metal conduit and UL listed sealing fittings with
conductor seals.
CAUTION: Do not run AC power wires or non-pump related wires, such as price signs or
intercoms, in the same conduit as data communication wiring. Refer to the Field
Wiring and Communication Diagram Current Loop, Generic Current Loop, and RS-
485 for additional information.

Safety Instructions
3000 Series Installation Manual iv
CAUTION: Data wires (two 18-gauge per fueling position) are dedicated to a particular
fueling position. To prevent damage to the electronic circuit boards, do not mix
the data wires, or connect them to any other data wires.
CAUTION: Dispenser must be installed with a suitable power operated pump incorporating
a provision for expansion relief, which will relieve at pressures not to exceed 50psi

unless provided with relief valve.
CAUTION: Use a separate circuit breaker for each pump motor. Do not run the pump motor
on the same circuit breaker as any other power circuit for the dispenser.
CAUTION: Do not drill holes in the fuel dispensers to mount additional signage. Holes can
introduce water, cause failure of the electronic equipment, and will void the
warranty.
IMPORTANT: Alternative fuels, such as E25, E85, and other ethanol blends, may require special
piping materials or components. Consult with the piping manufacturer to
determine that the piping material, fittings, and connectors are compatible with
alcohol-blended fuel.
IMPORTANT: All installations of Bennett products and accessories (i.e., nozzles, hoses, and
breakaways) must be performed by a trained and licensed technician accordance
to all codes, standards, and regulations.

Site Preparation
3000 Series Installation Manual Back to TOC 12
5SITE PREPARATION
Bennett Pump is not responsible for any damage to the dispenser or for improper operation due to
accidents, abuse, or faulty installation.
Installation specifications will vary by location; however, this manual assumes certain basic preparations
have been met prior to installing the dispenser. This section outlines those basic assumptions.
Existing sites replacing dispensers must clean and leak test tanks, remove any accumulated water, and
route new communication wires through rigid metal conduits to validate the equipment warranty.
Prior to dispenser installation, a new site should contain:
•A UL containment sump designed for the Bennett dispenser (or appropriate adapter). Follow the
containment sump manufacture’s installation instructions.
•One remote pump for each product which delivers the product within the specified pressure
and flow ranges of the dispensers plumbed to the dispenser location.
•Wiring from the AC Power Panel, Submersible Pump Relays, Forecourt Controller, and Point of
Sale (POS) routed to the pump location via rigid metal conduit which complies with all Federal,
State, and Local Codes.
•A concrete foundation upon which the dispensers will be mounted and anchored. Do not pour
concrete around the product pipes or electrical conduit.
5.1 UNDERGROUND AND ABOVEGROUND STORAGE TANKS
Underground and aboveground storage tank installations must conform to:
•Environmental Protection Agency (EPA) regulations
•National Fire Protection Agency NFPA 70: National Electrical Code (NEC)
•NFPA 30A: Code for Motor Fuel Dispensing Facilities and Repair Garages
•NFPA 30: Flammable and Combustible Liquids Code
•International Fire Code (IFC)
•All state and local codes
Follow Petroleum Equipment Institute’s Recommended Practices for Installation of Underground Liquid
Storage Systems RP100 and/or Recommended Practices for Installation of Above Ground Storage
Systems for Motor Vehicle Fueling RP200, http://www.pei.org.
CAUTION: The air eliminator (copper) tube must remain open to the atmosphere for proper
ventilation.
Always test new and used storage tanks prior to use. When a new dispenser is attached to an old
installation, the tanks should be cleaned and tested for leaks. Any water accumulation in the tank must

Site Preparation
3000 Series Installation Manual Back to TOC 13
be removed. Note: Tank testing should be done by a qualified professional. Refer to the Environmental
Protection Agency for Underground Storage Tanks (USTs) Laws and Regulations.
IMPORTANT: Bennett Pump is not responsible for any damage to the dispenser or for improper
operation due to accidents, abuse, or faulty installation. We highly recommend
installing new wires in the underground metal conduits to validate the equipment
warranty.
5.1.1 ABOVEGROUND STORAGE TANKS
Bennett Self-Contained dispensers work with aboveground storage tank installations if the following
requirements are met.
•Suction pumps: 10-foot maximum static lift.
•An Underwriters Listed (U.L.) Pressure Regulating Valve designed for under-the-pump mounting
is installed for each pumping unit according to the valve manufacturer’s instructions.
•Any additional valves suggested by the Pressure Regulating Valve manufacturer are installed
according to the manufacturer’s recommendations.
•The storage tanks should be as close to the dispenser as possible. In hot climates or high
altitudes, the distance should be very close to prevent vapor lock.
•The horizontal pipe length between the self-contained dispenser and the underground storage
tank should be 60 feet or less.
•Anti-siphon valve at the tank.
5.1.2 UNDERGROUND STORAGE TANKS
Remote pumps:
•The underground storage tanks for self-contained dispensers should be as close to the dispenser
as possible. In hot climates or high altitudes, the distance should be very close to prevent vapor
lock.
•The horizontal pipe length between the self-contained dispenser and the underground storage
tank should be 60 feet or less.
•The horizontal pipe should be at least 18 inches deep, to prevent vapor lock and keep the
dispenser functioning properly.
Suction pumps:
•All joints in the product line must be tight. The product line must not sag or have any high spots.
•Flex pipe must be used at the ends of the horizontal pipe between the dispenser and the tank.
Flex pipe prevents leaks that could develop through ground movement, settling of the tank,
frost heaving, or pump island settling. The joint under the dispenser also aids proper alignment
of the product union or coupling.

Site Preparation
3000 Series Installation Manual Back to TOC 14
•All piping must be clean of foreign debris such as oil, grease, and shavings. All connections must
be liquid tight to prevent leaks. Flexible Connectors must be listed and labeled according to UL
2039, Standard for Flexible Connector Pipe for Fuels.
•All piping shall be supported and protected against physical damage, including damage from
stresses arising from settlement, vibration, expansion, or contraction. The installation of
nonmetallic piping shall be in accordance with the manufacturer’s instructions.
5.2 PLUMBING REQUIREMENTS
CAUTION: Dispenser must be installed with a suitable power operated pump incorporating
a provision for expansion relief, which will relieve at pressures not to exceed
50psi (345MPa). Do not use line check valve between dispenser and operated
pump unless provided with relief valve.
IMPORTANT: Alternative fuels, such as E25, E85, and other ethanol blends, may require
special piping materials or components. Consult with the piping manufacturer to
determine that the piping material, fittings, and connectors are compatible with
alcohol-blended fuel.
5.2.1 CONTAINMENT SUMP
•Identify type of sump the dispenser will be installed upon and follow the manufacturer’s
installation instructions.
•Review the Footprint Drawings in the Appendix, compare the measurements of the dispenser
sump, adjust if necessary.
•If no containment sump is used, follow all piping backfill and compaction instructions observed
by national, state, NFPA, and local codes.
