Installation
4. Place the assembly on a balancing beam and, while maintaining the cradle centered on the pipe,
slide the camera along the cradle's grooves until the camera and cradle remain balanced on the
beam (see FIG. 16). Verify the balance with a spirit level.
5. Mount the camera as close to the Tilt Hub as possible to obtain a true center of gravity. The center of
gravity is the location on the long axis of the camera/lens assembly around which the camera and
mount balances.

screws on the underside of the camera mount.
10. Secure the support bracket to the Tilt Hub (at the same position marked for the iris alignment) on the
PTE-300 with some or all of the four 1/2" screws and washers.
11. Secure the camera/mount to the support bracket by using the two 1/2" screws.
12. Support the weight of the camera cables with a wire tie attached to the wire tie mount on the lower
corner of the face of the PTE-300 (FIG. 13).
The camera/lens cradle can be mounted on either side of the cradle support bracket.
