GreenAPU recommends installing the power unit behind the passenger side diesel tank. A minimum of 26 inches of free space along the frame is recommended. The power unit may also be mounted in a different location should more space be needed.


Make sure that the unit can be accessed for service and sufficient clearance is present to open the front cover. If possible, avoid mounting the unit underneath the truck cabin or sleeper for safety reasons. In addition, avoid placement locations near any hot components, such as the DPF system. In some cases modifications to the fairing, fender, or diesel tank may be required to properly install the unit.
