Occupational Safety and Health Act (OSH Act).
3. Always disconnect the power source before
working on or near the ventilating fan, motor or
junction box.

grease, hot surfaces, chemicals or other objects.
5. Do not kink the power cord.
6. Do not install the unit where ducts are confugured
as shown in Fig.A.
7. Provide suction parts with proper ventilation.
8. This unit is UL Listed for use over a bathtub or
shower when installed in a GFCI protected branch
circuit.
9. These ventilating fans are intended for residential
usage only.
10. This product is designed for ceiling mount
installation.
WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC
SHOCK, OR INJURY TO PERSONS, OBSERVE THE
FOLLOWING:
1. Use this unit only in the manner intended by the
manufacturer. If you have questions, contact the
manufacturer.
2. Before servicing or cleaning the unit, switch the
power off at the service panel and lock the service
disconnecting means to prevent the power from
being switched on accidentally. When the service
disconnecting means cannot be locked, securely
fasten a prominent warning device, such as a tag,
to the service panel.
3. Installation work and electrical wiring must be
done by a qualified person(s) in accordance with
all applicable codes and standards, including fire-
rated construction.
4.
Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of
fuel burning equipment to prevent backdrafting.
Follow the heating equipment manufacturer’s
guideline and safety standards such as those
published by the National Fire Protection
Association (NFPA), and the American Society
for Heating Refrigeration and Air Conditioning
Engineers (ASHRAE) and local code authorities.
5. When cutting or drilling into the wall or ceiling,
do not damage electrical wiring and other hidden
utilities.
6. Ducted ventilating fans must always be vented to
the outdoors.
7. If this unit is to be installed over a tub or shower, it
must be marked as appropriate for the application
and be connected to a GFCI (Ground Fault Circuit
lnterrupter) – protected branch circuit.
8. Do not use this unit with any other solid-state
control device. Solid-state controls may cause
harmonic distortion, which can cause a motor
humming noise.
9. NEVER place a switch where it can be reached
from a tub or shower.
10. Not to be installed in a ceiling thermally insulated
to a value greater than R40. (This is required for
installation in Canada only).
11. Do not open/disassemble LED light engine.

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. 3” 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.
