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. 4” circular duct is recommended
for installation. The ducting from this fan to the
outside of building has a strong effect on 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
reduce energy 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.
External timer/dimmer switch can be used. Please
contact Delta Breez customer service and consult
with a licensed electrician for compatibility.
