Product Usage Instructions

WARNING: To ensure safety and proper functioning of the product, please follow these instructions:

1. Use the product only as intended by the manufacturer. If you have any questions, contact the manufacturer.
2. Prior to servicing or cleaning the unit, switch off the power at the service panel and lock the service disconnecting means to prevent accidental power switch-on. If locking is not possible, securely attach a warning device to the service panel.
3. All installation work and electrical wiring must be carried out by a qualified person in compliance with applicable codes and standards, including fire-rated construction codes and standards.
4. Ensure sufficient air supply for proper combustion and exhaust of gases through the flue (chimney) of fuel burning equipment. Follow the heating equipment manufacturer’s guidelines and safety standards, as well as those published by relevant organizations.
5. When cutting or drilling into walls or ceilings, be cautious not to damage electrical wiring and other hidden utilities.
6. Always vent ducted fans to the outdoors.
7. Use only an ON/OFF switch, mechanical timer, or relay-switched control.
8. If installing over a tub or shower, connect the unit to a GFCI-protected branch circuit.
9. Ensure proper grounding of the unit.

CAUTION: Additional considerations for product usage:

1. Use the product for general ventilating purposes only. Do not use it to exhaust hazardous or explosive materials and vapors.
2. This product is designed for installation in flat ceilings. The motion sensor may not function reliably if the product is installed in a non-flat ceiling. Do not mount the product in a wall.
3. Avoid getting drywall spray, construction dust, or any other debris on the power unit to prevent motor bearing damage and noisy/unbalanced impellers.
4. Refer to the specification label on the product for further information and requirements.

Installation:

For a typical installation, follow these steps:

1. Ensure proper insulation placement around and over the fan housing.
2. Connect the power cable to the fan housing.
3. Seal any gaps around the housing.
4. If using round ducts, seal the duct joints with tape.
5. For optimal performance, use the shortest and straightest duct routing possible. Avoid installing the fan with smaller ducts than recommended.
6. Consider using insulation around the ducts to reduce energy loss and inhibit mold growth.
7. Install a roof cap or wall cap with a built-in damper for venting the duct to the outdoors.

Note : Insulation, round elbows, round ducts, roof caps, and wall caps may need to be purchased separately.

Ventilation Fan with Motion Sensor

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 at the address or telephone number listed in the warranty.

Typical Installation

• Installation is the same for:
• Fits in 2″ x 8″ ceiling construction.
• Infinitely adjust the fan position between joists from 14″ to 24″ on center.

The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and en-ergy use of the fan. Use the shortest, straighest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce en-ergy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow. 6-inch round rigid metal duct is recommended for best performance.

New Construction Installation

Tools needed

• Power screwdriver with a Phillips bit
• Phillips screwdriver
• Flathead screwdriver
• Pliers
• Wire insulation stripper
• Wire cutter

Materials needed

• 6″ round metal ducting recommended for best performance. Use of other ducting is acceptable but may impact performance.
• Roof cap or wall cap (built-in damper recommended)

   • Use proper UL-approved connectors to secure wiring to the Knockout Plate provided in Parts Bag.
   • Connect wires as shown in wiring diagram.
   • See OPERATION section on page 12 for details.
   • MASTER switch turns fan system on and shuts it off for fan cleaning and maintenance purposes.
   • The SENSOR/CONTROL switch turns motion control automatic operation on/off.
   • MANUAL-ON switch directly increases fan operation to certified airflow rate.
   • MASTER and SENSOR/CONTROL switches can be combined (see page 10).
   • MASTER switch along with or separate from SENSOR/CONTROL switch may be located where it is not easily accessed for everyday usage; they may need to be labeled and located where it can’t be turned on without being seen from fan to comply with local and national codes.
6. Insert Mask and Finish Ceiling
   • Install ceiling material.
   • Cut out around Housing. CAUTION: IN ORDER TO PREVENT MOTOR/CONTROL DAMAGE: If the blower was unplugged, power must be disconnected (see page 2, WARNING item 2) before inserting motor plugs into control assembly.

When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel.

Operation

It is normal for this ventilation fan to take approximately 5 seconds to start running after it is turned on.

Modes
(For reference, wiring diagrams are on pages 5 and 10.)

Continuous ventilation:

1. Turn master wall switch on.
2. Fan operates at user-adjustable airflow rate.

Motion sensing:

1. If master wall switch is not already on, turn it on.
2. Turn sensor/control wall switch on. Some installations may not have a separate sensor/control wall switch; where it is combined with master wall switch.
3. Fan operates at certified airflow rate and sensor detects motion.
4. When no more motion is detected, fan enters time delay mode. (See below.)

Manual-on (optional manual-on wall switch must be installed):

1. Turn master and manual-on wall switches on (sensor/control wall switch can be on or off).
2. Fan operates at certified airflow rate.
3. When manual-on wall switch is turned off, fan enters timed-off mode.(See below.)

Time Delay:
Fan continues to run at cerified airflow rate until user-adjustable TIME delay has passed, then fan reverts to user-adjustable airflow rate.

• To Set the User-Adjustable Airflow Rate
  Using a small, flat-blade screwdriver, carefully rotate the CFM adjustment until the arrow points to the desired airflow rate.

• To Set the User-Adjustable Time Delay
  Using a small, flat-blade screwdriver, carefully rotate TIME adjustment until the arrow points to the desired minutes of time delay.
  The user-adjustable controls are located in one corner of the Fan Housing, behind the Grille.

• To Turn Fan OFF
  Turn the master switch OFF.

Cleaning and Maintenance

CAUTION

IN ORDER TO PREVENT MOTOR/CONTROL DAMAGE:

• DO NOT remove motor plug to stop spinning motor.
• Power must be disconnected (see WARNING at top left of this page) before motor plug is removed or inserted into control assembly.

To Clean

1. For quiet and efficient operation, long life and attractive appearance, remove Grille and vacuum interior of unit with a dusting brush attachment.
2. Do not use cleaning sprays, solvents or water on, or near, the sensor.
3. Motor is permanently lubricated and never needs oiling. If motor is making excessive or unusual noises, replace Control Assembly and Motor.

Troubleshooting

Before continuing, turn off power as previously noted in WARNING and CAUTION sections at the top of the previous page.

Symptom : Fan does not run.

• Check for an open fuse or circuit breaker in building’s service panel.
• Check two (2) plug-in connections for Motor and its Control are seated firmly in place.
• Check two (2) plug-in connections for Sensor and its Control are seated firmly in place.
• Check that Blower Wheel spins freely.

Symptom : Motion mode does not operate fan at certified air flow rate.

• Check two (2) plug-in connections for Sensor and its Control are seated firmly in place.

Symptom : Fan runs erratically.

• Check that Blower Wheel is firmly attached to Motor shaft and both spin freely. Symptom: Fan seems noisy.
• Check that back draft damper in fan’s Duct Connector pivots freely. Screws used to attach duct to Duct Connector may prevent damper from opening.
• Check that back draft damper in wall or roof cap pivots freely. Dampers are sometimes mistakenly painted shut or obstructed by bird or insect debris. Symptom: Fan does not properly ventilate room.
• For spot ventilation, turn both master switch and sensor/ control wall switch ON, so sensor/control operates fan at certified airflow rate.
• For spot ventilation followed by continuous ventilation, increase the “TIME” setting of user-adjustable time delay.
• For continuous ventilation, increase “CFM” setting of user-adjustable airflow rate.
