Conventions used in this manual
This manual includes safety precauons and other important informaon presented in the following format:
NOTE: This provides helpful supplementary informaon.
IMPORTANT: This provides instrucons to avoid damaging hardware or a potenal hazard to the environment, for example: fuel leakage from
equipment that could harm the environment.
CAUTION: This indicates a potenally hazardous situaon that could result in minor or moderate injury if not avoided. This may also be used to
alert against unsafe pracces.
WARNING: This indicates a potenally hazardous situaon that could result in severe injury or death if not avoided.
DANGER: This indicates an imminently hazardous situaon that will result in death if not avoided.
Operating precautions
Franklin Fueling Systems (FFS) equipment is designed to be installed in areas where volale liquids such as gasoline and diesel fuel are present.
Working in such a hazardous environment presents a risk of severe injury or death if you do not follow standard industry pracces and the
instrucons in this manual. Before you work with or install the equipment covered in this manual, or any related equipment, read this enre
manual, parcularly the following precauons:
IMPORTANT: To help prevent spillage from an underground storage tank, make sure the delivery equipment is well-maintained, that there is a
proper connecon, and that the ll adaptor is ght. Delivery personnel should inspect delivery elbows and hoses for damage and missing parts.
CAUTION: Use only original FFS parts. Substung non-FFS parts could cause the device to fail, which could create a hazardous condion and/
or harm the environment.
WARNING: Follow all codes that govern how you install and service this product and the enre system. Always lock out and tag electrical
circuit breakers while installing or servicing this equipment and related equipment. A potenally lethal electrical shock hazard and the possibility
of an explosion or re from a spark can result if the electrical circuit breakers are accidentally turned on while you are installing or servicing this
product. Refer to this manual (and documentaon for related equipment) for complete installaon and safety informaon.
WARNING: Before you enter a containment sump, check for the presence of hydrocarbon vapors. Inhaling these vapors can make you dizzy or
unconscious, and if ignited, they can explode and cause serious injury or death. Containment sumps are designed to trap hazardous liquid spills
and prevent environmental contaminaon, so they can accumulate dangerous amounts of hydrocarbon vapors. Check the atmosphere in the
sump regularly while you are working in it. If vapors reach unsafe levels, exit the sump and venlate it with fresh air before you resume working.
Always have another person standing by for assistance.
WARNING: Follow all federal, state, and local laws governing the installaon of this product and its associated systems. When no other
regulaons apply, follow NFPA codes 30, 30A, and 70 from the Naonal Fire Protecon Associaon. Failure to follow these codes could result in
severe injury, death, serious property damage, and/or environmental contaminaon.
WARNING: Always secure the work area from moving vehicles. The equipment in this manual is usually mounted underground, so reduced
visibility puts service personnel working on it in danger from moving vehicles that enter the work area. To help prevent this safety hazard, secure
the area by using a service truck (or some other vehicle) to block access to the work area.
DANGER: Make sure you check the installaon locaon for potenal ignion sources such as ames, sparks, radio waves, ionizing radiaon,
and ultrasound sonic waves. If you idenfy any potenal ignion sources, you must make sure safety measure are implemented.

REPAIRING THE DEFENDER SERIES®OVERFILL PREVENTION VALVE SHELL
The shells of some Franklin Fueling Systems Defender Series®Overll Prevention
Valves (OPVs) are glued. If you have one of these OPVs and the glue has come free,
use the following procedure to install screws to hold the OPV shell in place.
Required equipment:
• Two M3 self-tapping, athead screws, 6 mm length
• Drill
• 2.75 mm drill bit
• 6.5 mm countersink bit
• Loctite®262 (red)
• Metal punch
• Hammer
• Metal grinder or metal le
• Screwdriver
1. Remove the OPV and drop tube assembly from the ll point, and move them to a
safe location, outside of the hazardous zone.
2. Remove the OPV from the drop tube assembly. Make sure there is no fuel in the
OPV, and allow it to dry for at least 20 minutes.
3. Seat the shell fully onto the shoulder of the OPV body, and drill two 2.5 mm holes
through the shell (8 mm deep), into the OPV body. (Do not break through the OPV
body!) Position the holes 13.2 mm from the edge of the shell nearest the OPV. The
holes should be 140° apart, centered around the OPV pivot.
4. Remove the OPV shell, and use the countersink bit to countersink the holes to
6.5 mm.

5. Re-install the shell. Align the holes in the shell with the countersunk holes in the
OPV body.
6. Use the metal punch to carefully dimple (or press or form) the OPV shell into the
countersunk holes in the OPV body. This allows you to countersink the screws when
you install them.

7. Apply red Loctite®262 to the screw threads, and tighten them into the holes.
8. Use the grinder or le to grind off any part of the fastener head above the outside
diameter of the shell.
9. If the oat link is missing or broken, use the link provided in the kit, and install the
1/4" pin (larger end) toward the oat and the 1/8" pin (smaller end) toward the coupler
arm.
10.Use the remote tool to verify the functionality of the OPV.
11. Reinstall the OPV into the drop tube assembly, and then reinstall both into the ll
point.
12.Use the remote tool to verify the functionality of the OPV.
