Step 8 - Install The Retaining Ring - AMX HPX-1600 Installation Manual

Step 8 - Install the Retaining Ring

1.
Insert the four #6-32 x 1 3/8 retaining screws into the retaining ring.
Note the orientation of the retaining ring. This orientation changes in order to accommodate the various
thicknesses of mounting surfaces (see FIG. 8 on page 11).
Note the direction of the screw bosses.
For mounting surfaces less than 35mm thick, orient the screw bosses away form
the main assembly (down).
For mounting surfaces greater than 35mm thick orient the screw bosses toward the
main assembly (up).
2.
Place the retaining ring over the lower portion of the base assembly and against the underside of the
mounting surface.
3.
If an accessory mounting bracket HPX-AC-MB (FG559-21) is to be used, install it now by trapping it
between the retaining ring and mounting surface (FIG. 19).

Ensure the unit is properly aligned in the mounting surface.
Torque the retaining screws to approximately 3 in-lbs.
Do not over tighten the screws.
Over tightening the retaining screws can cause the system to bind.
If the system binds, gradually loosen the retaining screws until it operates smoothly.
