Connecting Pump/Dispenser Inlet Pipes
To aid in the alignment and positioning of piping, it is always recommended that the unit is not
anchored securely to the island until the piping is completely aligned and tightened.
Use of incompatible materials or components with E85 or DEF can result in leaks. For
E85, unexpected failures of components may also occur resulting in fire or explosion or
environmental damage. When installing components in E85 units, refer to
“Important
Requirements for E85 Units” on page 6-1 .
When dispensing alternative fuels such as E85 or fluids such as DEF, verify with the
manufacturer if the material of all plumbing components are compatible with the fuel
(E85) or fluid being dispensed.
Do not replace the dispenser or pump parts with those incompatible with the fuel
involved.
WARNING
WARNING
Shear valves must be installed correctly. Improperly or insufficiently anchored shear
valves can lead to fire or explosion. Fire/explosion can result in severe injury or death.
For DEF units product spills may occur. Anchor all shear valves as per the
manufacturer’s instructions. AST installations require a pressure regulating valve at the
base of the pump.
Applicable to Dispensers Rated for E85 Use:
Do not use tape at the very end of the pipe nipple to avoid tape entering the dispenser
hydraulics. Tape in the hydraulics can cause failures of valves, nozzles, or other
significant problems.
Use only UL-listed TPS PTFE pipe sealant manufactured by SAF-T-LOC International
Corp.
Use only UL-listed Taega Technologies Inc. Teflon tape.
Note: Teflon tape must be used only at the inlet pipe connection.
CAUTION
Shear valves are not required in pumps, except in special circumstances. Following procedure
for a pump is identical to that of a dispenser, except that a shear valve may not be used. The
contractor must provide and install pipe unions, irrespective of whether shear valves are used
or not.
For units with shear valves, the contractor-provided union must be installed on the shear valve.
For proper tightening of the union to the shear valve, refer to the “shear valve manufacturer’s
instructions”. For units without shear valves, the contractor-provided union must be installed
on the ground stub pipe.
