WIRING Plan to run 120vAC house wiring (with ground) from power source, through a standard wall switch to junction box in fan housing. INSTALLATION IN A NEW CONSTRUCTION SITE PREPARATION Refer to Figure 1. 1. To remove blower/power unit assembly from housing: A. Unplug power unit. B. Remove screw (located next to plug-in receptacle) which holds blower/power unit mounting plate in place. Save screw. C. Lift mounting plate at end near the plug-in receptacle until blower wheel clears the scroll. D. Remove plate by pulling its tabs out of slots in housing. Set blower/power unit aside until needed. 2. Remove one of the wiring knockout from housing. MOUNTING THE HOUSING Mounting Using Mounting Tabs Refer to Figure 2. 1. Locate fan housing next to ceiling joist. 2. Use wood screws (not provided) to loosely attach the housing to ceiling joist through the keyhole slots in mounting tabs. 3. Adjust housing so that it will be flush with finished ceiling. For the grille to fit properly, housing’s rim must not extend beyond finished ceiling surface. 4. When housing is properly adjusted, tighten screws in slots. Mounting Using Hanger Bars (Hanger bars sold separately, order model HB4) Refer to Figure 3. 1. Insert hanger bars in slots provided in housing. 2. Locate fan housing between joists so that the bottom of the housing is even with the planned finished ceiling. Extend the hanger bars to the joists. 3. Use screws or nails (not provided) to secure hanger bars to ceiling joists. INSTALLING THE DUCTWORK 1. Refer to Figure 2. Place duct collar over flanges at discharge opening of fan. Secure collar by snapping tabs into slots in flanges. 2. Run 4" round duct from outside to fan's discharge opening. 3. Connect duct to fan's duct collar. WIRING All wiring must comply with local codes and unit must be properly grounded. 1. Run 120vAC house wiring (with ground) from wall switch to fan location. 2. Pull wire through access hole and into junction box. 3. Refer to Figure 4. Use approved wire nuts to connect house supply wires to fixture wires as follows: white to white; black to black. Connect green or bare ground wire to green ground lead. POWER/BLOWER UNIT INSTALLATION 1. Place power/blower unit into housing so that mounting plate's tabs insert into slots in housing. 2. Press other end of mounting plate down until it is firmly seated over scroll and plug-in receptacles. 3. Secure mounting plate to housing with provided screw. 4.

After determining desired location for fan, drill a small hole in the ceiling. Place a coat hanger or other stiff wire up through hole to help in locating from above. 2. Place fan housing on top of ceiling surface, against a ceiling joist and use the housing as a template to mark area to be cut out. 3. After cutting out opening, mount housing in the opening using the hanger bars (sold separately) or mount directly to joist using mounting tabs. A. Insert hanger bars in slots in housing. B. Position housing in opening so that bottom of housing is flush with ceiling. C. Use screws or nails (not provided) to secure hanger bars to ceiling joists. D.
