Installing the Craft Interface on the Front Impeller Assembly

To attach the craft interface to the front impeller assembly, follow this procedure:

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. Make sure the router is attached to a proper earth ground. For more information about ESD, see Preventing Electrostatic Discharge Damage.
2. Place the replacement impeller assembly top side up on an antistatic mat on a flat, stable surface.
3. Attach the craft interface to the front of the impeller assembly, making sure that the hooks on the back of the craft interface clip securely into the windows on the front of the impeller assembly (see Figure 73).
4. Align the holes in the three semicircular metal tabs on the back of the craft interface with the corresponding holes in the top of the impeller assembly.
5. Insert the screws you saved when removing the craft interface into the three holes and tighten using a Phillips screwdriver (see Figure 72).
