Installation
Important Notes
The HFSF1 can be installed in a variety of ceiling environments. The use of the TBSF
(Tile Bridge Support) accessory may be desired.
For suspended ceilings, the use of both the TBSF Tile Bridge and CK10 Safety
Cable is strongly recommended to help support and distribute the weight of the
speaker.
The HFSF1 requires a minimum of 7-1/8" of vertical clearance between the front of
the mounting surface and any other structure for the speaker to fit.
The edge of the hole must be a minimum of 1-1/4" away from any side obstructions to
ensure that they will not interfere with the action of the clamps.
Beginning Installation
1. Begin by cutting a 6-1/4" circular hole where the speaker will be installed. A card-
board template is provided with the HFSF1 and should be used as a guide for
making the cutout in the ceiling or sheetrock.
2. Tighten the mounting clamps by turning the clamping screws clockwise. Do not over-
tighten the clamps – only tighten until the speaker is snug in the mounting hole.
If using an electric driver, set the clutch on the driver to the lowest setting.
