Reinstall the Lower Impeller Assembly

The lower impeller assembly is located just above the air intake on the front of the chassis, behind the craft interface (see Figure 1). To reinstall it, follow this procedure (see Figure 37):

1. Attach an ESD strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
2. Grasp the sides of the lower impeller assembly, and align the rear of the tray with the slider bars inside the chassis.
3. Slide the assembly all the way into the chassis.
4. Using a Phillips screwdriver, tighten the three captive screws at the bottom edge of the assembly to seat it firmly in the chassis.
