INSTALLATION IN
EXISTING CONSTRUCTION
Installing a ventilator in an existing construction site requires at least a small accessible area (attic or crawl space) above the planned installation location.
Review “INSTALLATION IN A NEW CONSTRUCTION SITE” and follow all instructions which apply to your installation.
LOCATION: Locate ventilator next to a ceiling joist.
WIRING AND DUCTING: Refer to Figure 6 for wiring and
to Figure 2 for ducting. Plan ducting and wiring before proceeding with installation.
CAUTION: Check the area above the planned installation to be certain that:
1.Ductwork can be installed.
2.Wiring can be run to the planned location.
3.No wiring or other obstruction will interfere with the installation.
INSTALLATION FROM ACCESSIBLE AREA ABOVE (using headers)
Refer to Figure 9.
1.From below the installation site, drill a small hole in ceiling at the planned location. Stick clothes hanger through hole to help locate it.
2.Locate hole in attic or crawl space.
3.In attic or crawl space, mark ceiling for cutout by using the housing as a template. Cutout dimensions: 103⁄16" x 141⁄2". The short side (103⁄16") of the cutout must be right next to the ceiling joist.
4.Mark cutout along marked line.
NOTE: If ceiling is plaster, cutout should be made from below to avoid chipping plaster.
5.Install headers between joists using nails or screws leaving 103⁄16" between them.
6.Install brackets upside down on housing's long dimension using hex nuts.
7.Mount damper section to housing, install housing and connect wiring and ductwork. Install power unit/blower assembly and grille.
