DO NOT MOUNT THIS PRODUCT IN A WALL.
3. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off
power unit.
4. Please read specification label on product for further information and requirements.
For quiet and efficient operation, long life, and attractive appearance - lower or remove grille and vacuum interior of unit with the dusting

ses, replace the motor with the exact service motor. The impeller should also be replaced.
VENTILATION FAN
MODEL:OD22025
a). Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.
b). Before servicing or cleaning unit, switch power off at service panel and lock the service disconnecting means to prevent power
from being switching on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning
device, such as a tag, to the service panel.
c). 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 codes and standards.
d). 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 the local code authorities.
e). When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
f). Ducted fans must always be vented to the outdoors.
g). Acceptable for use over a tub or shower when connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch circuit
(ceiling installation only).
h). This unit must be grounded.
i). Not for Use in Kitchens.
k). To reduce risk of fire and to properly exhaust air, be sure to duct air outside – Do not vent exhaust air into spaces within walls or
ceilings or into attics, crawl spaces, or garages
l). WARNING: To Reduce The Risk Of Fire Or Electric Shock, Do Not Use This Fan With Any Solid-State Speed Control Device.
m). The fan must not be installed in a ceiling thermally insulated to a value greater R40.

HUMIDITY SENSOR
The humidity-sensing fan uses a sophisticated humidity sensor that responds to: (a) rapid to moderate (user-adjustable) increases in
humidity or (b) humidity above a user-adjustable set-point (50%-100% relative humidity). The humidity sensor may occasionally turn the
fan ON when environmental conditions change. If the fan continuously responds to changing environmental conditions, “H” (means
“humidity”) adjustment may be required. This figure is factory-set for about 75% (Ambient temperature of 25℃).
SENSITIVITY ADJUSTMENT
The “H” has been factory set for most shower applications. However, if the fan is in a tub area or is being used for dampness control,
the “H” may need to be increased toward maximum “+”. If the control is responding too often to changing environmental conditions,
movement toward less “-” “H” may be required.To adjust the “H”:
1. Disconnect power at service entrance. 2. Through the grille, locate the slot marked “H”. 3. Carefully rotate the “H” adjustment
toward “+” or “-”. 4. Turn on power and check operation by turning on the shower or other humidity source until the fan turns on.
5. Repeat above steps if necessary. When the temperature changes, humidity sensor values will have deviation.
TIMER ADJUSTMENT
The humidity sensing fan has a “T” (means timer) that can be adjusted from 5 to 60 minutes (factory-set at about 20 minutes). This “T”
controls the length of time that the fan remains ON after the sensor has stopped sensing a rise in humidity and the humidity level is
below the user-adjustable set-point. To adjust the “T”:

1. Disconnect power at service entrance;
2. Through the grille, locate the slot marked “T”;
3. Carefully rotate the “T” adjustment to desired setting
4. Check operation by turning on a humidity source until the fan turns on.
5. Turn humidity source off and time the unit.
6. Repeat above steps if necessary.
Fan with ADD on Motion Sensor Grille
7 to 9 feet
The fan and motion sensor can be operated separarely.See “Connect Wiring” for details.(Fig.4)
Sensing distance will be impacted of the body’s own situation (for example, the thinner
people wearing the more remote sensing distance). Turn on the switch sensor the fan
don’t work. When enter the gesture area fan will run at the certified airflow rate,
indicator light begins flashing. When persons leave, indicator light turn down, the fan
remains working until the delay time(3-30minutes) has passed, and then the fan stops.
Installation distance: 7 to 9 feet.
Sensing range is within the cone angle of 90°.
One LED light is a sensor indicator and the other 5 LED light are the night light which is operated by a switch.

3. MOUNT WITH MOUTING HOLES
Select the appropriate size of the wood is installed between the joists using
screw (not included). Hold housing in place so that the housing contacts the
bottom of the joist and woods, Screw housing to joist and woods through
the hole.（Fig.2）
4. INSTALL ROUND DUCTWORK
Connect the round ductwork (not included) to the damper/duct connector,
and run the ductwork to a roof or wall cap (not included). Using tape (not
included), secure all the ductwork connections so that they are air tight.
Run 120 V AC house wiring to the location of the fan. Use only UL-approved connectors (not included) to attach the house wiring to the
wiring plate. Refer to the wiring diagram, and connect the wires as shown.

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 reduce energy loss
and inhibit mold growth. Fans installed with existing ducts may not achieve
their rated air flow.
