Flange (Permanent Trim) for Grid / T-Bar Ceiling
The AstroHood
™
S-III RSR unit is installed from the top side of the suspended ceiling grid/T-bar with
the integral flange resting on the grid/T-bar. If no gasket is present in the ceiling grid, the AstroHood
unit should be sealed to the grid using RTV (Dow Corning 732 or GE 102 is recommended).
1. Thoroughly clean the mating surfaces of the unit flange and ceiling grid to remove any debris or
residue that may inhibit an adequate seal.
2. Apply a continuous, small bead (~ ¼" diameter) of RTV to the mating surface of the grid/T-bar.
3. Center and lower the AstroHood unit into the opening and seat the unit onto the grid/T-bar. Apply
uniform pressure to ensure the flange is bonded to the grid/T-bar (see Fig. 02).
4. Remove excess RTV.
