Before Placing Unit on Fuel Island
High alcohol percentage fuels such as E85 or fluids such as DEF may be incompatible
with certain plumbing materials and hydraulic components.
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.
WARNING
Note: Before mounting the unit on to the fuel island, read and understand this section
completely. This information is essential to avoid installation errors.
Verifying and Determining Plumbing Requirements
Before placing the unit on an island, determine the correct location of piping and orientation of
the unit involved. A common installation error is to install the unit backwards, which results in
expensive modification for reinstallation later. This section contains information regarding
plumbing requirements for various models.

Do not make assumptions about configurations based on previous experience, hose
positions, or layout of the unit being replaced, whether replacing a Gasboy unit or that
of any other manufacturer.
IMPORTANT INFORMATION
Determining the Unit Orientation
To ensure proper unit orientation, perform the following:
• Mount the unit using the mounting bolt locations specified. Seal the base as required.
• Fill in any openings to the potentially larger pit box opening. Seal as required.
• DEF cold weather units are front load units. Ensure that the hose can be used at only

180 degrees from the front of the unit. That is, the hose is not used at a position directly
behind the unit. Reorientation of the unit may be required to avoid operation in this
manner.
Determining the Unit Side and Type
Before lifting units on to the island, ensure the following:
• To determine the unit type, refer to the unit’s model sticker.
Note: The model sticker is located at particular places and can be viewed by removing the
bezel. In mechanical units, it is on the inside, left side of the top housing. In
electronic computer units, it is on the electronics base plate in the front of the top
housing.
• To locate the appropriate configuration for your unit, refer to “Foundation Diagrams” on
page A-3 .
• DEF cold weather units are front load only units. DEF warm weather units can be side
load or front load units.
