Review "INSTALLATION IN A NEW CONSTRUCTION SITE" and
follow all instructions which apply to your installation.
LOCATION: Locate fan between ceiling joists.
WIRING AND DUCTING: Plan ducting wiring before proceeding with
installation. Refer to Figure 4 for wiring and Figure 3 for ducting.
CAUTION: Check area above planned location to be sure that:
1. Ducting can be installed or that area is sufficient for proper venting.
2. Wiring can be run to the planned location.
3. No wiring or other obstruction might interfere with installation.

joists are.
Locating Joists – Lightly tap the ceiling. A hollow sound means
no joist; a solid sound means a joist is present. To be sure you
have located a joist, drill a small hole (
ceiling with a wire.
2. Locate the joists. Drill a starter hole in the ceiling between the
joists.
3. To exactly locate the edge of joist, saw a line from hole to joist.
4. Refer to page 1. Remove power/blower unit from housing.
5. Use the housing pan as a template to mark cutout: place pan
centered between joist and trace around pan.
