PREPARATION

Tools Required for Assembly (not included): Hammer,
Flathead Screwdriver, Wire Nuts, Nails, Duct Tape,
Phillips Head Screwdriver, Utility Knife
Helpful Tools (not included): Electric Drill, Drill Bits
WARNING: Turn off electricity at breaker box before
beginning installation.
Carefully remove unit from carton.
Check area above installation location to be sure that
wiring can run to the planned location and that duct
work can be run. Make sure the area is sufficient for
proper ventilation.
Inspect duct work and wiring before proceeding with
installation.
Before installation, provide inspection and future
maintenance access at a location that will not interfere
with installation work.
You may need the help of a second person to
install this fan: one person on the attic side and one
on the room side.
Note: Installations may vary depending on how the
previous bath fan was installed. Supplies necessary for
the installation of your bath fan are not all included.
However, most are available at your local home
improvement or hardware store.
Proper insulation around the fan to minimize building
heat loss and gain. 6" circular duct is recommended for
installation. The ducting from this fan to the outside of
building has a strong effect on the air flow, noise and
energy use of the fan. Use the shortest, straightest duct
routing possible for best performance,and avoid installing
the fan with smaller ducts than recommended. Insulation
around the ducts can reduceenergy loss and inhibit
mold growth. Fans installed with existing ducts may not
achieve their rated air flow.

The fan will operate most efficiently when located
where the shortest possible duct run and minimum
number of elbows will be needed.
Use a roof cap or wall cap that has a built-in damper
to reduce backdrafts.
