Installer: Leave this manual with the homeowner.
CAUTION
CLEANING & MAINTENANCE
OPERATION
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
1. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
2. This product is designed for installation in ceilings up to a 12/12 pitch (45 degree angle). Duct connector must point up. 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 brush attachment.
The motor is permanently lubricated and never needs oiling. If the motor bearings are making excessive or unusual noises, replace the motor with the
exact service motor. The impeller should also be replaced.
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.
j). 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
k). WARNING: To Reduce The Risk Of Fire Or Electric Shock, Do Not Use This Fan With Any Solid-State Speed Control Device.
l). The fan must not be installed in a ceiling thermally insulated to a value greater R40.
7 to 9 feet

HUMIDITY SENSOR FOR
Do not use a dimmer switch to operate the humidity control or motion control.
SENSOR OPERATION
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 (For SE90TMH
，
fan run continuously at a pre-set lower level (setted by toggle switch) and automatically boost up to certified
airflow rate 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 at 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 FOR
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 (from 5 to 60 minutes).
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.
MOTION SENSOR FOR
SE90TH SE90TMH
SE90TH SE90TMH
SE90TMH SE90TM
The fan and light can be operated separarely.
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 system begins working,
the fan run continuously at a pre-set lower level. 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(can be adjusted from 3 to 30 minutes) has passed,
and then the fan transferred to the pre-set lower level.
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.
