WARNING
Assembly and installation of Reflector/Backstructure should only take place when
winds are less than 15 mph (24 km/h) to prevent damage to reflector panels and ease
the assembly process. Follow special instructions stenciled on crate relative to crate
opening, contents removal and/or personnel safety.
Note
Lubricate bolt threads of both stainless steel and A325 hardware with supplied Stick
Wax (200852) to reduce friction. Do not allow wax under flat washer.
