Introduction
Do not perform any procedure in this Special Instruction until you read this information and you understand this information. This Special Instruction describes the procedures required in order to install the Selective Catalytic Reduction (SCR) Module on the above generator sets. Wiring harnesses and lines groups connecting to the dosing cabinet have additional length to allow routing to any of the four corners.
Note: The additional length must be bundled in a safe location in order to prevent any trip hazards.
