NEW HOME INSTALLATION
1. Attach duct adapter to housing by first hooking two mounting tabs
over flange in discharge opening. Pivot duct adapter insuring aligning
tabs are inside opening and align two locking tabs with small
rectangular holes. See Fig. 4. Press tabs firmly into holes to lock.
NOTE: The attachment of the duct adapter to the housing may be
reinforced if desired, by installing two #8AB screws through holes in
the duct adapter and the small holes in the housing.
2. Remove grille assembly carefully and place in a safe location.
3. Before removing main unit from carton, loosen the two heater
retaining screws “A” (Fig. 1). Pull plug “P” from its receptacle.
Squeeze the heater frame to release the heater retaining bracket and
carefully lift out the heating unit until the screws disengage the
keyholes. Place in a safe location.
4. Check the ventilating section. Be sure that the motor bracket is
secured tightly to the cover plate. If not, loosen the two mounting
screws, twist the motor bracket counter-clockwise into place and
retighten the screws.
5. Next, pull the plug “R” form its receptacle, remove the retaining screw
“B” and lift out the ventilating section. Be careful not to disturb the fan
blade. Save the retaining screw.
6. Insert mounting brackets into the slots on housing, with angles
pointing away from housing. Position housing into ceiling location.
Housing should extend 3/8” for drywall or 3/4” for standard sheetrock
and plaster below joist. Pull mounting brackets against ceiling joists
and fasten securely. (Fig. 5)
