10. IMPORTANT: If the combined width of the Joist/Truss thickness, ceiling and subfloor require ASLL Blower sleeve to be expanded
over 13”, adhere both air flow leakage stickers over electrical relief slot opening in Outer Sleeve to prevent air leakage into joist/truss cavity,
(See Diagram K1).
11. Install the Outer Sleeve over Blower Housing. CAUTION: When installing Outer Sleeve make sure electrical relief opening is on the
side electrical enters ASLL, (See Diagram L1).
12. Using the (4) provided black screws, align holes on ASLL Outer Sleeve mounting bracket with holes in sheetrock mounting brack-
