CAUTION

PLEASE READ THE INSTRUCTIONS BEFORE COMMENCING INSTALLATION AND RETAIN THEM FOR FUTURE REFERENCE.
Electrical products can cause death or injury, or damage to property. If in any doubt about the installation or use of this product, consult a competent electrician.

CLEANING & MAINTENANCE

For quiet and efficient operation, long life, and attractive appearance — lower or remove the grille and vacuum interior of the 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.

OPERATION

Fan with no accessories — Use an ON/OFF switch to operate this fan. See the wiring diagram on page 4 of this instruction manual. Fan with ADD on Humidity Sensor and no wall switch (see the wiring diagram on page 5 of this instruction manual) Fan with ADD on Humidity Sensor and a wall switch to manually activate the fan (The fan and humidity sensor can be operated separately by a wall switch. See the wiring diagram on page 4 of this instruction manual for more details)
Humidity Sensor
The humidity-sensing fan uses a sophisticated humidity sensor that responds to: (a) rapid to moderate (adjustable by user) 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 +25ºC)
OPERATION
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, the movement toward less “-” “H” may be required. To adjust the “H”:

1. Disconnect the power at the service entrance
2. Through the grille, locate the slot marked “H”
3. Carefully rotate the “H” adjustment toward “+” or “-“
4. Turn ON the power and check operation by turning on the shower or other humidity source until the fan turns on
5. Repeat the above steps if necessary. When the temperature changes, humidity sensor values will have a 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 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 the power at the service entrance
2. Through the grille, locate the slot marked “T”
3. Carefully rotate the “T” adjustment to the desired setting
4. Check the operation by turning ON a humidity source until the fan turns on
5. Turn humidity source off and time the unit 6. Repeat the above steps if necessary

Fan with ADD on Motion Sensor Grille
The fan and motion sensor can be operated separately. See the wiring diagram on page 4 of this instruction manual for details. Sensing distance will be impacted of the body’s own situation (for example, the thinner people wear the more remote sensing distance).
Turn on the switch sensor system begins working, and the fan runs continuously at a pre-set lower level. When entering the gesture area fan will run at the certified airflow rate, and the indicator light turns on.
When the person leaves, the indicator light turns down, the fan remains working until the delay time (3-30 minutes) has passed, and then the fan is transferred to the pre-set lower level. Installation distance is 7-9ft. The sensing range is within the cone angle of 90º
Fan with ADD on Speed Controller
Use a 2 function wall control. See the wiring diagram on page 4 for details. Set the motor speed as you need. Max airflow is HVI-certified performance based on HVI procedures 915, 916, and 920. Another airflow reference performance is based on HVI procedures 915, 916, and 920.
Fan with ADD on Light Kit and Night Light
Use a 3-function wall control. See the wiring diagram on page 5 for details.
Instruction Manual

Types of Typical Installation

1. Housing mounted to I-joists (start at “Assembly Instructions 1” below)
2. Housing mounted to joists (start at “Assembly Instructions 1” below)
3. Housing mounted to truss (start at step “Assembly Instructions 2” below)

Assembly Instructions

1. Mount Housing to Joist or I-joist Holds the housing so that it is in contact with the bottom of the joist. Attach the housing with four (4) screws to the joist through the holes in each mounting flange.

2. Mount with Hanger Bars
   a) Sliding hanger bars have been provided, which allow the housing to be positioned accurately anywhere between the framing. The bars span up to 24″ and can be used on all types of framing: I-joist, standard joist, and truss construction. Slide hanger bars onto the housing and adjust as needed to fit between framing
   b) 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 b) hanger bar. Select a proper hole and secure the hanger bars together using flange screws.

3. Attach Damper/Duct Connector
   Snap the damper/duct connector onto the fan housing. The connector MUST be flush with the top of the housing, and the damper flap should fall closed. An insulated flexible duct is recommended for the quietest possible installation. If a rigid duct is used, a short (1-3ft) section of the insulated flexible duct will ensure quiet operation

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. The ducting from this fan to the outside of the building has a strong effect on the airflow, 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 airflow.

Connect Electrical Wiring
Run 120V 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 below, and connect the wires as shown.

Install Grille

Install ceiling material to complete the ceiling construction. Then, cut around the fan housing. First, insert the sensor plug into the plug base on the power box, and then install the grille (for fan with motion sensor).
To attach the grille assembly to the fan housing, pinch the grille springs on the sides of the grille assembly, and position the grille into the housing with the grille springs in the appropriate slots. Push the grille assembly towards the ceiling to secure.
Install Accessories
If need to add accessories function (humidity sensor, motion sensor, speed controller, etc.), put the relevant power box in the place like the diagram on the left, fix it with screws, and insert the plug from the box into the suitable wire panel. (Motion function also needs to change grille with sensor system). Connect electrical wiring while referring to the wiring diagram above on this page of the instruction manual.

SERVICE PARTS

WARNING Before replacing, be sure to turn OFF the power at the power source.

• Blower Assembly includes parts 6, 5, d, 4, c, b, a.
  Replacement installation:
  Remove the screw (part c), then take out the motor plate (part 4) from the housing (part 9) by pushing down the rib in the plate while pulling out on the side of the housing. Replace the broken parts.
