4 Slowly pour the fluid compound into the sealing fitting, up to a level below the threads in the
close-up plug.
Note: Pour the fluid slowly to avoid trapping air bubbles in the seal.
5 Immediately wipe off any spilt compound and close the seal with a close-up plug.
Notes: 1) The initial setting of the sealing compound will occur within 30 minutes. The
compound requires a minimum of eight hours at a temperature above 32 °F (0 °C)
to develop sufficient strength to withstand explosion pressures.
2) If the pump/dispenser has a factory mounted TopKAT PLUS, for LAN/WAN wiring
requirements and sealing CAT-5 cable, refer to MDE-5013 TopKAT PLUS
Installation Manual.
Plumbing Requirements
High alcohol percentage fuels such as E85 may be incompatible with certain plumbing
materials and hydraulic components.
Use of incompatible materials or components with E85 or DEF can result in leaks or
unexpected failures of components 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, verify with the manufacturer if the
material of all plumbing components are compatible with the fuel (E85) or fluid being
dispensed.
WARNING
Pipe Installation
Refer to “PEI Publication RP100 Recommended Practices for Installation of Underground
Liquid Storage Systems (Chapter 9)” and “PEI Publication RP200 Recommended Practices for
Installation of Aboveground Storage Systems for Motor Vehicle Fueling”. Product inlet pipes
and vapor pipes for Gasboy pumps/dispensers vary in location between models. See the

model-specific footprint.
• Check national, state, and local regulations for the installation of the pipe system.
• Use the containment system as required by national, state, and local regulations.
• Use a new black iron pipe constructed of UL-approved pipe material and UL-approved
fittings.
• Use a 1-1/2-inch pipe for the riser-to-pump or dispenser.
• Use 2-inch risers on high-volume units that use a 2-inch shear valve.
Pipe Size
The required pipe size depends on the number of sharing lines that the unit contains, size of
STPs (dispensers only), and length of the run.
