The grille should be installed when the finished ceiling is in place. Installation in an existing, finished building requires an accessible area (attic or crawl space) above the planned location. See “INSTALLATION IN EXISTING CONSTRUCTION.” Do not install closer than 12 inches to a vertical surface. Do not install over tub or shower enclosure. UNIT DIMENSIONS Refer to Figure 1 for housing’s dimensions. NOTE: If there will be a finished second floor above, the Model 9905 housing requires a minimum of 2" x 8" joist construction for mounting. WIRING AND DUCTWORK 1. Run the required wiring during rough-in stage of construction. 2. Total connected load: 1630 watts. 3. Plan to run 120vAC, 60 Hz wiring (with ground) on a separate 20 Amp circuit from a power source, through the provided wall switch, to the housing’s junction box. See wiring diagram. 4. Use 4" round duct. INSTALLATION IN NEW CONSTRUCTION PREPARATION 1. Loosen hanger bar brackets to allow bars to be inserted. 2. Refer to Figure 2. Insert hanger bars into brackets. 3. Refer to Figure 3. Slide hanger bar brackets down to end of slot closest to outside edge of housing. Tighten brackets in this position. 4. Refer to Figure 4. Remove junction box cover by removing one screw. 5. Refer to Figure 4. Remove appropriate wiring knockout(s) and install approved box connector(s).

Using nails, secure hanger bars to joists. NOTE: The hanger bar brackets are adjustable. Allowing for the thickness of the finished ceiling, mount hanger bars so that edge of housing will be flush with the finished ceiling. 3. Adjust brackets as required. Tighten brackets. INSTALLING THE DUCTWORK 1. Refer to Figure 5. Install duct collar. 2. Using 4" round duct, connect duct to collar and tape connection. INSTALLING THE SWITCH 1. Install double-gang switch box in chosen location. 2. Refer to Figure 6. Run wiring and make wiring connections. 3. Use supplied screws to secure switch bracket assembly to switch box. 4. Using supplied screws, secure wall plate to switch bracket. INSTALLING AND CONNECTING THE WIRING Refer to Figure 6. All wiring must comply with local codes and unit must be properly grounded. 1. Using 12-gauge wire, run 120vAC, 60 Hz wiring (with ground) from a power source to the wall switch location. The unit must be wired on a separate 20 Amp circuit. 2. Run wiring from switch location to housing as shown in the wiring diagram. 3. Make wiring connections as shown in wiring diagram. 4. Replace junction box cover. Slide slotted hole in cover over screw. Tighten screw securely. 5. Secure wire cover with one screw. 6. Insert heater and ventilator plugs into proper receptacles as shown. MOUNTING THE GRILLE ASSEMBLY 1. Refer to Figure 7. Using two screws (provided), secure grille to housing.

If the location that has been chosen for installation has a finished floor above it, be certain there is sufficient space available to install the housing and make the necessary duct connection. PLANNING Review “INSTALLATION IN NEW CONSTRUCTION” and follow all instructions that apply. CAUTION: Check the area above the planned location to make sure that: (1) Ducting can be installed or that the area is sufficient for proper venting. (2) Wiring can be run to the planned location. (3) No wiring or other obstructions might interfere with the installation. INSTALLATION 1. The housing must be mounted between ceiling joists. 2. Refer to Figure 8. Mark ceiling for cutout. Cutout dimensions: 141.8" long x 97.8" wide. Make cutout in ceiling. 3. Follow steps under “PREPARATION” page 1. 4. From above, lower housing into the cutout and secure hanger brackets. Install duct collar, connect duct, and run wiring through box connectors. 5. From below, adjust housing so that it is flush with the finished ceiling. 6. From below, make wiring connections as shown in figure 6. 7. Replace junction box cover. 8. Insert heater and ventilator plugs into proper receptacles. 9. Install grille.
