Site Preparation Plumbing Requirements
Page 30 MDE-4333E Atlas Fuel Systems Site Preparation Manual · November 2011
For Installation of Aboveground Storage Systems for Motor Vehicle Fueling, refer to PEI
Publication RP100 Recommended Practices for Installation of Underground Liquid Storage
Systems (Chapter 9) and PEI Publication RP200 Recommended Practices. Refer to
model-specific footprint before installing pipes.
• Check national, state, and local regulations for installation of pipe system.
• Use containment system as required by national, state, and local regulations.
• Below the unit, use new black iron pipe. Non-metallic UL and code approved flexible pipe
is also acceptable, constructed of UL-approved pipe material and UL-approved fittings.
Use of galvanized pipe is acceptable as an alternative to black iron pipe, when black iron
pipe is specified.
• Use 1-1/2-inch pipe for riser-to-pump or dispenser.
• Use 2-inch pipe for riser to pump or dispenser for Super-Hi
™ and Ultra-Hi ™ models.
Since DEF is very susceptible to contamination, ensure that all piping is clean before
and during installation.
IMPORTANT INFORMATION
Notes: 1) When pipes are shared by different pumping units, special installation
considerations are required to prevent one unit from draining the other during
fueling.
2) A dedicated line is recommended to supply each self-contained pump.
Pipe Size
The required pipe size depends on the number of units sharing lines, size of the STPs
(dispensers only), and length of the run. Use the following guidelines.
Note: At locations dispensing Urea, the product line from the tank to the dispenser must not be
exposed to sunlight unless a reflective material is used on the piping.
Piping and Plumbing Components (DEF)
Piping and Plumbing Components must be compatible with DEF. Typical piping used is either
stainless steel or High Density Polyethylene (HDPE). In environments where temperatures
drop below 15
° F, external components must be insulated and heated as required to prevent
freezing. Thermostatic control of the heater circuit is recommended where heating commences
above 15
° F.
Pumps (Standard Flow)
Use new 2-inch, 2-1/2-inch, or 3-inch pipe. Use 2-inch pipe for runs up to 50-feet to a single
pump. Increase to 2-1/2-inch or 3-inch pipe for longer runs up to 75-feet to a single pump with
maximum lift condition. A dedicated line is recommended to supply each self-contained
pump.
Pumps (High Flow, Super-Hi, Ultra-Hi)
Use new 3-inch, 3-1/2-inch, or 4-inch pipe. Use 3-inch pipe for runs up to 50-feet to a single
pump. Increase to 3-1/2-inch or 4-inch pipe for longer runs up to 75-feet to a single pump with
maximum lift condition. A dedicated line is recommended to supply each self-contained
pump.
