CAUTION
CLEANING & MAINTENANCE
OPERATION
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 at the
address or telephone number listed in the warranty.
2. Before servicing or cleaning unit, switch power off at service panel and lock the service disconnecting means to prevent
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 codes and standards.
4. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equip ment 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.
5. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. Acceptable for use over a tub or shower when connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch
circuit (ceiling installation only).
8. This unit must be grounded.
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.
Use an on/off switch to operate this fan. See “Connect Wiring” for details.
The humidity control and fan can be operated separately. Use a 1 or 2 function wall control. Do not use a dimmer switch
to operate the humidity control or light. See “Connect Wiring” for details.
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. 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 “-”.

2. Mount with mountion holes and hanger bar
Slide one hanger bar into the channel on the housing and adjust as
needed to fit between framing. Hold housing in place so that the housing
contact the bottom of the joist, Screw housing to joist through the hole A
and hole B. Screw the hanger bar onto the other side of joist through the
hole (refer to the right diagram).

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 (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.

3. Mount with hanger bars only
Slide hanger bars onto housing and adjust as needed to fit between
framing. Extend the hanger bars to the width of the framing. Position the
ventilator with the hanger bar tabs wrapped around the bottom edge of
the framing, holding the ventilator in place.
Secure hanger bars to framing using one screw on each end of hanger
bar. (refer to the right diagram)

4. Mount to I-joist
Slide one hanger bar (long) into channel B on the housing and adjust as
needed to fit between framing. Hold housing in place so that the housing
contacts the bottom of the joist. Screw housing to joist through the hole D
and hole C. Screw the hanger bar onto the other side of joist through the
hole (refer to the right diagram).

5. 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.
