Bennett dispensers are bolted to a pallet and then carefully packaged with cardboard/styrofoam liners
and a cardboard exterior carton. The entire package is then securely wrapped with plastic shrink wrap.
Use a fork lift to lift the dispenser while it is still on the pallet.
Before signing the freight delivery receipt, inspect the carton and pallet for any obvious signs of damage
that may have damaged the dispenser. If any damage is found, instruct the delivery driver to make a
notation on the delivery receipt before signing it. If possible, open the carton and inspect the dispenser
before signing the delivery receipt.
Bennett dispensers are shipped Ex-Works. This means that the title to the equipment passes to the
purchaser at the time the equipment is loaded on the truck at our factory. Freight damage claims are
the responsibility of the purchaser. Bennett will assist in preparing any damage claim, by helping
identify and price any parts necessary to make needed repairs.
Carefully remove the plastic shrink-wrap from the carton. Then carefully remove the cardboard
container and any inside liners. DO NOT DISCARD THE PACKAGING. Should the need arise to
repackage the dispenser, the cardboard packaging can be reused. Plastic shrink-wrap can be
purchased at office supply stores or industrial packaging stores.
Examine the exterior panels for any signs of freight damage. If damage is found after signing for
delivery, call the freight carrier immediately and request an inspection. DO NOT DISCARD THE
PACKAGING; the inspector will want to examine it.
Once you are sure that there is no freight damage to the exterior of the dispenser, use the door key
(wire tied to the nozzle hook) to unlock the lower door. Remove the lower door from both sides of the
dispenser. Visually examine the interior of the dispenser for shipping damage. While the dispenser is
extremely sturdy, a dispenser that has been “dropped” can suffer damage internally even while it
appears normal on the exterior.
Read the model/serial plate of the dispenser and check to confirm that the hydraulic configuration
matches the order specified.

The dispenser is bolted to a pallet with bolts and nuts. With the lower doors removed and safely stored
away, remove the nuts and bolts that secure the dispenser to the pallet as shown in figure 1 and figure
2.
Thread two lifting straps (900 lbs. Capacity each minimum) through the dispenser as shown in figure 3
and figure 4. Be careful not to allow the straps to go under any of the hydraulic castings such as the
meter outlet, copper tubes or valves. The straps should be lifting only against the front and rear chassis.
Use a forklift or pallet lifting device with the forks spread wider than the pump and gently lift the
dispenser. This lifting method will also work on the high hose dispenser. Place the dispenser gently on
the island using care to line up the base anchor bolt holes with the anchor bolts embedded in the
concrete island.
WARNING: Lift only to the height required to set the dispenser on the island. Keep hands
and feet clear of the dispenser while it is suspended in the air.

Lifting the Dispenser from Above - On the high hose models, there are lifting brackets provided in the
upper area of the dispenser. There is a cover that has to be removed to access these brackets. (See
figure 5 and figure 6 below).
Figure 5 - Cover is screwed onto the top of the dispenser
and must be removed to access the lifting brackets. Figure 6 - After the top cover is removed, the lifting brack-
ets can be accessed for lifting the dispenser from above.
The dispenser must be bolted firmly to the concrete island. The dispenser base is provided with anchor
bolt holes (see base drawings in back of this manual for dimensions). Anchor bolts embedded in the
concrete island must be not less than ½” diameter. The threaded ends of the anchor bolts should
project 1-1/2” above the concrete.
On the Low Hose dispenser, 2 anchor bolts required minimum.
On the High Hose dispenser, 4 anchor bolts required minimum in the outer 4 mounting holes.
Refer to the Footprint Drawings in the back of this manual for hole locations.
When anchoring the dispenser, always level the dispenser with shims before bolting to the island. Place
the shims at the location of the anchor bolts so the dispenser frame is not distorted when the anchor
bolts are tightened down.

Step 1: Determine the type of supply line needed from the model number’s 7th position on the
serial tag. If the model number is 3711SNR (Note the R) the dispenser will require a submerged pump
and pressurized supply line for each product. If the model number is 3711SNS (Note the S) the pump
will require a suction supply line for each product.
Step 2: Determine the number of product pipes required by finding the model number below.
Model Number Product Supply Lines Required
3711 / 3811 Use 1 product line plumbed to position 1.
3712 / 3812 Use 1 product line plumbed to position 1.
3722 / 3822 Use 1 product line plumbed to position 1 and 1 product line plumbed to position 2.
*Refer to base drawings in the back of this manual for product inlet locations.
Pipe Size - The 3000 Series do not come with an inlet pipe or joint. The customer is responsible for the
1 1/2” NPT inlet pipe. These will thread directly into the inlet casting (see figure 7, figure 8 and figure 9).
Determining the Number of Product Supply Pipes Needed
For remote dispensers, a U.L. Listed Emergency Shut Off Valve is required for each product inlet. The
Emergency Shutoff Valve can be referred to as an “Impact Valve”, “Safety Valve”, “Shear Valve”,
“Crash Valve”, or “Fire Valve”. The Emergency Shut Off Valve must be supported by the island frame or
containment sump frame. Follow all instructions contained in the valve’s installation manual and
observe all national, state, NFPA, and local codes.
For self-contained
(suction) pumps, a
vertical check valve is
required under each
of the pump’s ground
joint unions for the product inlet. The vertical check valve ensures that the
pump’s hydraulic system remains full of product, and it is necessary to
maintain the “prime” of the suction line so that liquid product does not drain
back to the tank. Follow all instructions contained in the vertical check
valve’s installation manual and observe all local codes.
Product inlet locations and dimensions are on the footprint foundation
drawings in this manual.
Listed ground joint union must be installed between sheer section of
Emergency Shut Off valve and dispenser inlet. If rigid product inlet pipes
are used, they must be plumbed so no strain is exerted on the dispenser chassis caused by tightening
down the unions.
For dispensers used with companion satellites, follow all federal, state, and local codes regarding
installation of impact valves.
Install an approved emergency shut off valve, designed to close automatically in the event of severe
impact or fire exposure, in the dispenser supply line at the base of the dispenser. The valve will also
permit safe inspection and maintenance. Follow the installation instructions for the valve being
installed (see figure 10).

General -
The dispenser must be mounted on a concrete foundation. Do not pour concrete around the product
pipes or electrical conduit. The use of a UL approved containment sump designed for the Bennett
Dispenser Model used is highly recommended. Follow the containment sump manufacture’s installation
instructions for proper installation. If no containment sump is used, fill the sump area with clean sand or
dirt as far up the product pipe as possible once installation is complete. Use water to pack the sand in
place (see figure 11 and figure 12) .
Figure 11 - Example of Remote Figure 12 - Example of Self Contained
NOTE: All piping must be clean of foreign debris, such as: oil, grease and shavings. All
connections must be tight to prevent leaks.
Swing joints or flex pipe must be used at the ends of the horizontal pipe between the dispenser and the
tank (see figure 13). These joints prevent leaks which might develop through ground movement from
settling of the tank, frost heaving of the ground or pump island settling. The joint under the dispenser
also aids proper alignment of the product union or coupling.
Figure 13 - Underground Piping
Pipelines and Underground Containment Sumps
NOTE: Please refer to PEI/RP100 Recommended Practices. The installation must conform to
EPA, NFPA, and State regulations for underground storage tanks.
*Acceptance Varies by State*

Bennett self contained dispensers can be used with aboveground tank installations if the following
requirements are met:
 An Underwriters (U.L.) Listed 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 installation must be installed and used in accordance with Federal, State, Local, and National
Electrical code NFPA #70 and Motor Fuel Dispensing Facilities and Repair Garages code NFPA
30A.
 Follow PEI/RP200 Recommended Practices for Installation of Aboveground Storage Systems.

Electrical Wiring Section -
For 3700 go to page 20
For 3800 go to page 38
Find the wiring diagram specific to the dispenser model for the dispenser that is being installed in the
Wiring Diagrams section. Read and follow all directions including supplemental notes contained on the
drawing.
The dispenser’s field wiring connections are in the upper electronics head (electrical enclosure ) of the
dispenser. Or, the dispenser may have been ordered with the optional explosion proof junction box
located in the lower area of the dispenser. Using the door keys shipped with the dispenser, (on side 1)
unlock the two locks on the upper electronics enclosure and open the door to access the wiring terminal
on the CPU/ Control board. If there is a junction box then wire to the terminal strip and flying leads in
the junction box. Refer to the instructions for wiring to the junction box under the “Wiring Diagrams”
section of this manual.
All field wiring must be stranded copper, oil and gas resistant (THHN) color coded, with a 600 volt
insulation rating. See wiring diagrams section for proper wire sizes. Pull 72” extra wire to reach the top
of the dispenser. Do not use wire nuts. The ends of the wires should be clean and free from oxidation.
The wire separator (supplied with the pump) must be installed on the wires as they exit the conduit
located in the electrical enclosure before the wires are terminated in the electronics enclosure. The wire
separator is needed to properly seal the conduit in the last step of installation.
Underground conduit for the field wiring must be 3/4”, rigid metal and continuous. The use of PVC
conduit is not allowed. All conduit between the building and each dispenser should be a separate
conduit run.
For Remote dispensers Bennett requires the installation of RC networks across the coil and contactors
of the sub-pump relays for proper operation of the dispenser. Failure to install the RC networks will void
Bennett’s limited warranty.
Intercom wiring must be in a separate conduit from the dispenser conduit. DO NOT install intercom
wiring in the same conduit as the dispenser wiring or else the Bennett Warranty will be voided and
improper system operation will result.
Dispenser Electronic Power must be on a separate dedicated circuit breaker. Do not put submerged
pump or self-contained pump power on this circuit breaker. Up to two dispenser may be placed on (1)
15 amp circuit breaker. No more than two dispensers per 15 amp breaker. All dispensers at the station
must be on the same phase of power.
All dispenser field wiring between the building and the dispenser for power, neutral and ground wire
conductors must not be spliced, wire nutted or shared with any other equipment. Doing so would void
the Bennett Limited Warranty. All power, neutral and ground conductors shall be run from the dispenser
to the Main Service Panel.
Follow all local, state and federal requirements for installation of vapor seals.
Electrical contractors must pull 72” of wire above the grade level to reach through the
dispenser’s conduit and into the electrical area at the top of the dispenser. Read and follow all
instructions on the wiring diagram and observe all national and local electrical codes.
Electrical Field Wiring
General Information

19 120001 Rev K 1-19-18
In instances where new dispensers are replacing old dispensers, Bennett recommends that new wiring
be pulled to each dispenser.
If existing wiring is used (not recommended) and does not reach to the dispenser electronic head (top
area) of the dispenser, the wires can be extended only if the connections are soldered, weather proof
and contained in an explosion-proof type junction box. Follow all current national and local electrical
codes for extending wire runs.
The maximum distance from the breaker panel to the dispenser is 500 feet. For self-contained units
increase the motor wire size from 14Ga to 12Ga for runs over 50 feet, increase the motor wire size from
12Ga to 10Ga for runs over 100 feet and increase the motor wire size from 10Ga to 8 Ga for runs over
250 feet.
The power for the motors in 1 h.p. self-contained standard pumps must be located on the opposite
phase from the dispenser electronic power or be connected at 230V. This is necessary to limit the
electronic noise from feeding back into the dispenser’s electronic power. Failure to observe this will
create problems with the operation of the dispenser’s computers. Note: if 230v motor power is used be
sure to set the motor switch located on the motor to the high voltage setting by moving the switch to the
high position. Note: 2 h.p. Big Fueler motors do not have an adjustment switch. They must be wired for
230vac 1 phase, or 380vac 3 phase.
WARNING: DO NOT CROSS PHASE THE DISPENSERS OR DAMAGE WILL OCCUR. When
installing more than one dispenser the remote sub-pump relay control wire from each dispenser must be
on the same phase of power or cross phasing will occur at the sub-pump relay. This means that the
electronic power for all dispensers at the site must be on the same phase.
Electrical Conduits - Make sure that each dispenser has its own electrical underground conduit. Wiring
from multiple dispensers in a single conduit is not allowed. All underground conduit should be rigid metal
and drawn up tight. The use of PVC (plastic) conduit is not allowed and may void the Bennett Warranty.
Make sure that vapor “seal offs” are properly installed on all conduits at and from each dispenser. Make
sure any intercom wiring is not run with dispenser field wiring. A separate (second) conduit must be run
if using an intercom at the dispenser.

Once product piping and tanks have been tested for leaks and any leak conditions have been fixed then
the remote dispenser product lines must be purged of all air that may be trapped in the lines. All
electrical connections must be made and verified at this time.
CAUTION! DO NOT USE THE DISPENSER TO PURGE AIR FROM THE PRODUCT LINES.
RUNNING THE METER IN A DRY CONDITION AND AT THE HIGH SPEEDS RESULTING FROM
PRESSURIZED AIR, WILL DAMAGE THE METER AND VOID THE BENNETT LIMITED WARRANTY.
The emergency shutoff valve contains a test port that may be used to bleed off air that may be trapped
in the product lines. Manually close the emergency shutoff valve. Do not leave this process unattended
while purging the air from the product lines. Once liquid fuel product begins to weep from the test port,
retighten the plug in the test port. If more than one dispenser is on a submerged pump product feed
line, start this purging process at the dispenser furthest from the submerged pump and work backwards
toward the submerged pump.
WARNING! Take appropriate measures to contain any product seepage from the test port.
Dispose of any spilled product in proper manner consistent with applicable laws and codes.
Manually open the emergency shutoff valve and lock it into the “on” position according to the instructions
from the valve manufacturer. Use a test prover can or other appropriate approved container to dispense
50 to 100 gallons or 175 to 350 liters through the dispenser. Begin dispensing by only slightly opening
the nozzle to allow any entrapped air in the dispenser to slowly release through the nozzle. This
prevents an over-speed pulser error.
Once the dispenser has dispensed 50 gallons of fuel, the SB100 meter should be tested for calibration.
Refer to the section in this manual for calibration procedures.
Once product piping and tanks have been tested for leaks and any leak conditions have been fixed then
the self contained (suction) dispenser product lines must be purged of all air that may be trapped in the
lines. All electrical connections must be made and verified at this time.
The pumping unit evacuates all the air in the pipe before it gets to the meter. The air is expelled through
the vent at the top of the pumping unit. Nothing but fuel should pass through the meter. The meter will
not turn until fuel enters the pump and pressurizes the system.
WARNING! Take appropriate measures to contain any product seepage from the air elimination
chamber tube. Dispose of any spilled product in proper manner consistent with applicable laws
and codes.
Use a test prover can or other appropriate approved container to dispense 50 gallons or 175 liters
through the dispenser. Begin dispensing by only slightly opening the nozzle to allow any entrapped air
in the dispenser to slowly release through the air eliminator. This prevents over-speeding of the meter.
Once the dispenser has dispensed 150 gallons of fuel, the SB100 meter should be tested for calibration.
Refer to the section in this manual for calibration procedures.
