4. Cut Diffuser template on dashed lines. Align the top of template with the wall cut and center it so that there is an equal space
between the right and left edges of the template and ends of the cut in the sheetrock. Mark all 4 corners of template, connect with
a straight edge and cut Diffuser opening in wall (Diffuser opening should be 1 1/4” high x 13 5/8” wide), (See Diagram F).
5. Insert Diffuser with the air scoop on the back pointing towards the Blower. Adjust tangs on the sides if necessary to secure a tight fit
into the wall opening, (See Diagram G).
BLOWER INSTALLATION
IMPORTANT: Install Diffuser first when mounting the Blower down low and the Diffuser high so sheetrock from the Diffuser cut out does
not fall into wall cavity and damage Blower.
1. You must select a stud wall section that contains an electrical outlet, (See Diagram H). Mark a vertical line down the side of the outlet
box opposite stud. Mark a spot 3/4” above electrical outlet top mounting screw on outlet side opposite stud, (See Diagram H).
2. From the mark made in Step 1, use a level to draw a horizontal line across to opposite stud, (See Diagram I).
3. Using a hand sheet rock saw carefully make a horizontal cut along the line going away from outlet. Cut the sheetrock until you
come in contact with the opposite stud. NOTE: If studs are spaced greater than 16” o.c., the horizontal cut line should not
exceed 12 1/2”, (See Diagram J).
4. Align the top corner of AS1P Blower template with horizontal wall cut and vertical line. Mark all 4 corners of template, connect with a
straight edge and cut rectangular opening in wall (Model AS1P Blower opening should be 4 7/8” high x 12” wide), (See Diagram K).
5. With the Blower discharge pointing towards Diffuser rotate the mounting flange so that the electrical outlet cutout is positioned on the
side of the Blower housing nearest the electrical outlet. With the bent tabs facing the front of the Blower, slide the mounting flange
from the rear of the Blower to the front until the four tabs line up with the holes in the Blower housing. Secure Blower housing to
mounting flange with included 8/32 self tapping screws. NOTE: If electrical outlet is on the right side of Blower, loosen (2) power
switch bracket screws and slide power switch bracket completely over to the right to allow for proper alignment of switch opening on
Grille. Tighten (2) switch bracket screws, (See Diagram L).
6. Carefully insert the Blower into the cutout. Level the top flange and mark the larger Blower flange mounting holes. Using the provided
wood screws, secure the blower to the wall studs. Use provided wall anchors if not installing into studs, (See Diagram M).
