Typical Installation

Installation is the same for all models.

Diagram Description: A diagram shows the fan housing installed in a ceiling between joists. It indicates the placement of insulation around and over the fan housing, the power cable, the ductwork, and the roof or wall cap. Gaps around the housing and duct joints should be sealed.

• Fits in 2" x 8" ceiling construction.
• Infinitely adjust the fan position between joists from 14" to 24" on center.
• Can be installed between joists or trusses if the distance between them is 10 1/2".
• Do not install this fan in a ceiling thermally insulated to a value greater than R40.

Ducting Recommendation: The ducting from the fan to the outside of the building significantly affects airflow, noise, and energy use. Use the shortest, straightest duct routing possible. Avoid installing the fan with smaller ducts than recommended. Insulation around ducts can reduce energy loss and inhibit mold growth. 6-inch round rigid metal duct is recommended for best performance.

Operation

WARNING: Before servicing or cleaning, switch power off at the service panel and lock the service disconnecting means to prevent power from being switched on accidentally.

To Turn Fan ON

Turn the control switch ON. It is normal for the fan to take approximately 5-10 seconds to start running. The fan will run at the certified airflow rate if the boost switch is ON. The fan will run at low speed continuous airflow rate if the boost switch is OFF.

To Use Fan Time Delay Airflow Rate Change

1. Turn the control switch ON.
2. Turn the boost switch ON - the fan will run at the certified airflow rate.
3. When the boost switch is turned OFF, the fan will continue to run at the certified airflow rate until the user-adjustable time delay has elapsed, and then will automatically change to the low speed continuous airflow rate.

To Set the Low Speed Continuous Airflow Rate

Using a small, flat-blade screwdriver, rotate the CONTINUOUS RUN adjustment until the arrow points to the desired airflow rate.

To Set the User-Adjustable Time Delay

Using a small, flat-blade screwdriver, rotate the TIME adjustment until the arrow points to the desired time delay, shown in minutes.

*The user-adjustable controls are located in one corner of the Fan Housing, behind the Grille.

CAUTION: DISCONNECT ELECTRIC POWER SUPPLY AND LOCK OUT SERVICE PANEL BEFORE SERVICING THE UNIT. DO NOT remove motor plug to stop spinning motor. Power must be disconnected before motor plug is removed or inserted into control assembly.

Preventive Maintenance

For quiet and efficient operation, regularly clean the grille and interior of the unit.

To Clean the Grille

Remove the grille, use a mild detergent, and dry with a soft cloth. DO NOT USE ABRASIVE CLOTHS, STEEL WOOL PADS, OR SCOURING POWDERS.

To Clean Interior of Unit

Once the grille is removed, vacuum the interior of the unit with the dusting brush attachment.

Maintenance

The motor is permanently lubricated. If the unit makes excessive or unusual noises, replace the blower assembly.

Troubleshooting

Symptom: The fan does not run.

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

Symptom: The fan runs erratically.

• Check that the Blower Wheel is firmly attached to the Motor shaft and both spin freely.

Symptom: The fan seems noisy.

• Check that the back draft damper in the fan's Duct Connector pivots freely. Screws used to attach the duct to the Duct Connector may be preventing the damper from opening.
• Check that the back draft damper in the wall or roof cap pivots freely. These dampers may be mistakenly painted shut or obstructed by debris.

Symptom: The fan does not properly ventilate the room.

• For spot ventilation, turn both the boost switch and the control switch ON to enable the fan to run at the certified airflow rate.
• For spot ventilation followed by continuous ventilation, increase the "TIME" setting of the user-adjustable time delay.
• For continuous ventilation, increase the "CFM" setting of the low speed continuous airflow rate.
