Installation and Operating Instructions
VENTILATION FAN
READ AND SAVE THESE INSTRUCTIONS
GENERAL SAFETY INFORMATION
1. Make sure that the electric service supply voltage is AC
120V, 60Hz.
2. Follow all local electrical and safety codes, as well as
the National Electrical Code (NEC) and the
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.
4. Protect the power cord from sharp edges, oil, grease,
hot surfaces, chemicals or other objects.
5. Do not kink the power cord.
6. Do not install the unit where ducts are configured.
(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.
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 unit, switch 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 of Heating, Refrigerating 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 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 control device may cause harmonic
distortion, which can cause a motor humming noise.
(Avertissement: ne convient pas à des régulateurs de
vitesse à semi-conducteurs).
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 the LED light engine
Turning angle too large Duct shrink
Too many elbows Elbow near the body

CAUTION
1. For General Ventilating Use Only. Do Not Use To
Exhaust Hazardous Or Explosive Materials And Vapors.
2. Not for use in cooking areas. (Fig. B)
3. This product must properly connect to the grounding
conductor of the supply circuit.
4. To reduce the risk of injury to persons, install the fan at
least 8.2 feet (2.5m) above the floor.

PREPARATION
Tools Required for Assembly (not included): Hammer,
Flathead Screwdriver, Wire Nuts, Nails, Duct Tape, Phillips
Head Screwdriver, and 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. The ducting from this fan to the outside of the
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 reduce energy loss and inhibit mold
growth. Fans installed with existing ducts may not achieve
their rated air flow.

Locate unit above (GFCI-protected circuit required) or
within 5 feet of the shower head.

Locate unit away from heating or cooling sources
which can affect humidity levels.

Do not locate near window. Unit may respond to the
outdoor humidity level.

Unit must be installed in ceiling to properly sense
moisture.

Locate unit only on flat ceilings up to 12 feet high for
proper sensing.

Use a roof cap or wall cap that has a built-in damper to
reduce backdrafts.

External timer can be used in conjunction with single-
speed mode only, please contact Delta Breez customer
service and consult with a licensed electrician for
compatibility.

External dimmer can be used in conjunction with LED
light model, please contact Delta Breez customer
service and consult with a licensed electrician for
compatibility.

TROUBLE SHOOTING
PROBLEM
POSSIBLE CAUSE
CORRECTIVE ACTION
The fan is not turning on 1. Power off
2. Faulty switch
3. Faulty wire connection
1. Make sure power supply is on.
2. Test or replace switch.
3. Check wire in switch box.
The fan seems louder than it
should
1. CFM too great
2. Damper not working properly or
damaged
3. Bend in duct too close to fan
discharge
4. Fan discharge reduced to fit
smaller duct
5. Fan body not securely attached
1. Be sure the CFM rating on the fan matches the
size of your room.
2. Check damper to ensure it is opening and
closing properly. If the damper has become
damaged, please call Customer Service.
3. Be sure you do not have any sharp bends in
duct closer than 18 in. to the fan discharge.
4. Use recommended size ducting to reduce fan
noise.
5. Be sure the fan is securely attached to your
ceiling joists.
The fan is not clearing the
room 1. Insufficient intake airflow within room
2. Insufficient CFM
1. Be sure a door or window is slightly ajar or
opened to allow airflow. The fan is not able to
draw air out of the room without enough
airflow to draw in from.
2. Be sure the CFM rating on the fan matches the
requirements for your room size.
The light is not turning ON 1. Power off
2. Faulty switch
3. Faulty wire connection
1. Make sure power supply is on.
2. Test or replace switch.
3. Check wire in switch box.
