INSTALLATION PROCEDURES ____________________________________________________________________________________________

CAUTION

__________________________________________________

The panels contained in this crate must be properly handled to prevent damage during installation. Follow the procedure given below to ensure the panel is properly supported. A third person should be in the hub to install the screws which attach the panel to the hub. Do not walk in the reflector until all panels have been installed. As rivets are installed in concentric circles from the hub outward, weight may be applied over the ribs. Avoid putting weight on unsupported parts of the reflector panels or on ribs where rivets have not yet been installed. __________________________________________________

29. Open top of reflector panel crate marked "With Decal Panel" and the

labled "Open This Side Only." 30. Use two people to carry reflector panel using carrying points

illustrated in Figure 2-10. Lift panel as illustrated in Figure 2-11 and carry panel as illustrated in Figure 2-12. Do not carry panel as illustrated in Figure 2-13.

31. Attach reflector panel with ViaSat logo decal loosely to hub directly

over elevation actuator using 2 hex head screws (item 1 in Figure 2-14), 4 flat washers (2), and 2 hex nuts (3). Secure panel to ribs using rivets in outer corner holes which are just inside of rim. Rivets should be left loose at this time.

NOTE Do not fasten the remainder of the panel holes to the ribs at this time. Once all the panels have been placed onto the backing structure, the remainder of the rivets will be installed.

32. Repeat steps 30 and 31 for the next panel, but install it in the next

clockwise position on the ribs.
