Shutter Installation

STEP 10 — Unpack Model A3024 shutter and read instruc- tions included. Note that the first part of the shutter instruc- tions refer to cutting the shutter hole, which you have already done, and so they may be disregarded. Follow the remaining instructions to adjust springs so that shutters open and close freely. (See Fig. 8.)

STEP 11 — Mount shutter to joists directly below fan opening with wood screws provided. Note sheet rock must be cover- ing center joist before shutter is installed. Again, make sure both sides of shutter open and close freely. (See Fig. 9.)

STEP 12 — Return to attic and attach side panels to fan as shown using remaining short screws and washers. (See Fig. 10.) Bottom of panels should rest upon ceiling. Bend flaps on ends of panels back when inserting panels between joists. These flaps will then spring back to seal off any space between panel and joist.

STEP 13 — Fan installation is now complete. With control in “OFF” position turn on 120V power supply to fan. Test run fan through all speeds.
