STEP 2 - The 3-speed control packed with this fan is used to operate fan from a remote wall location. Generally the best location is in the hallway near the fan. The control should be in sight of the fan. Install a single switch box at the location chosen. STEP 3 - The wiring diagrams, Figs. 14 and 15, show two alternate methods of wiring fan and control. If the 120V power supply is available at the FAN, Fig. 14 should be followed. If the 120V power supply is available at the CONTROL, Fig. 15 should be followed. In either case, note that the BROWN control wire must be connected to the BLACK (hot) wire from the 120V power supply. FIG. 14 FAN MOTOR OUTLET BOX CONTROL OUTLET BOX CONTROL MOTOR 120V, 60 HZ GND.

WALL INSTALLATION (MODELS 3038R AND 3638R ONLY) THIS INSTALLATION IS TO BE USED ONLY IN AN ATTIC GABLE OR WALL WHICH FACES AN UNOCCUPIED AREA, AN AREA NOT READILY ACCESSIBLE TO PEOPLE OR ANIMALS. (DO NOT USE THIS INSTALLATION IN AN ATTIC WITH ANY TYPE OF LOOSE INSULATION.) All fans are factory assembled for ceiling installation and can be easily modified for wall mounting. The following steps describe this procedure and installation. STEP 1—Reverse rotation of motor by reversing yellow and purple lead connections in conduit box on motor. STEP 2—Remove blade by first loosening the two set screws in the hub. Now reverse the blade and reinstall onto motor shaft. Hub should be flush with the end of the motor shaft. Be sure set screws align with flats on shaft, then tighten bolt securely (150 lbs. of torque recommended). STEP 3—Construct wood frame as shown in Fig. 1. Use 2” x 4” or 2” x 6” (depending on thickness of wall where unit is to be mounted) framing lumber. “A” SEE CHART 4” OR 6” — DEPENDING ON THICKNESS OF WALL “B” SEE CHART FIG. 1 FIG. 2 FIG. 3 SECURE SHUTTER IN PLACE DRILL (4) - 1/4” HOLES - (1) IN CENTER OF EACH WITH WOOD OR LAG SCREWS FLANGE AS SHOWN. STEP 4—Drill (4) holes in fan housing as shown in Fig. 2. 11 STEP 5—Position fan on frame and secure with (4) wood or lag screws (number 12 x 1 1/2” preferred) through holes drilled in STEP 4. Position fan on frame and secure with (4) wood or lag screws (number 12 x 1 1/2” preferred) through holes drilled in STEP 4.

Make sure the shutter opens and closes freely. STEP 7—Stand assembly upright with motor at top and position shutter on outside of frame. Secure shutter with (8) wood or lag screws (number 12 x 1” preferred) through holes in shutter frame. See Fig. 3. STEP 8—To mount this attic fan in gable or wall, a box must be framed into wall construction as shown in Fig. 4. See wall opening in chart. FAN SIZE “A” & “B” DIMENSIONS WALL OPENING SIZE 30” 33 3/4” x 33 3/4” 34” x 34” 36” 39 3/4” x 39 3/4” 40” x 40” STEP 9—Insert frame containing fan and shutter assembly into opening with outside surface of shutter frame flush with outside surface of wall. STEP 10—Nail frame assembly securely in place. Moulding may be used outside to improve appearance, as shown in Fig. 5. Caulk around moulding to provide a water-tight seal. Follow wiring instructions on pages 11 & 12. 12 ACCESSORY CONTROL MODEL 1012A Timer Switch may be used to control the fan, if it is desirable to run the fan after retiring at night. Time switch can be set manually to run up to 12 hours, turning fan off automatically at the pre-set time. OPERATING HINTS AND SUGGESTIONS 1.
