INSTALLATION INSTRUCTIONS VERY IMPORTANT Please read before attempting installation The fan and shutter are designed for horizontal installation only—the louvers will not function in the vertical position. The wooden fan frame is installed on top of the joists, and the shutters open up between the joists, so the rough opening will be smaller than the fan frame size. Fan Size Shutter Rough Opening (L X W) 24-in. 30-in. 36-in.

Deciding on a Joist-In or Joist-Out Installation Joist-In Installation The ceiling joists will be left intact for this method. You will need another attic access, as the fan will not fit through the shutter opening with the joist(s) in place. Joist-Out Installation This method involves removing one or more ceiling joists. This is the preferred method, as the best location does not necessarily coincide with the position of the joists.

Step 2: Cut the Shutter Opening   Cut through ceiling along lines using a circular saw. Measure depth of drywall and adjust the saw so you only cut the drywall and avoid the joists. Carefully remove the drywall from the opening *Note* Make sure the exposed joist is centered if doing the joist-in installation. Step 3: Cut the Ceiling Joist (For Joist-Out Installation Only)     Stabilize the joists using 2 X 6 lumber to bridge the joist about six inches away from either side of the opening.

Step 5: Facing Installation   Use 2 X 6 boards to create a square with the inside dimensions being the same distance as the shortest dimension of the shutter rough opening (i.e. 26” for a 24-in model, etc.). Nail or screw in the facing to the framed opening. Joist-In Installation Joist-Out Installation TIP: If doing a joist-out installation, use lumber from the support pieces as the long cuts and the removed joists as the short cuts.

Step 6: Prepare and Install Fan Assembly (cont.)   Push fan assembly through the shutter opening diagonally or through another attic access if doing a joist-in installation. Place frame on top of facing or additional frame and draw alignment marks around the base of the assembly then secure to the facing using screws.

Step 8: Wiring Instructions (cont.)      Connect High speed motor lead (BLACK) to the top right terminal of High/Low switch (HIGH). Connect Low speed motor lead (RED) to the bottom left terminal of High/Low switch (LOW). Connect incoming common wire (WHT) to the common wire (WHITE) from the motor.
