Frequently Asked Questions - BFQ70W Air King

How to install the BFQ70W fan in an existing ceiling?

Cut an opening in the ceiling according to the template, then attach the mounting bracket to a joist. Snap the fan housing into the bracket and connect the duct. Ensure the power is off before any work.

What type of duct should I use?

It is recommended to use rigid duct of 4 inches or larger, preferably insulated, for better performance and noise reduction. Avoid flexible or smaller diameter ducts.

Can I use this fan in a kitchen?

No, use in a kitchen is prohibited. This fan is designed for general ventilation only and should not vent hazardous or explosive vapors.

How to clean the grille and inside of the fan?

Remove the grille and clean it with a mild detergent and soft cloth. For the inside, disconnect the motor and carefully vacuum the parts. Never immerse electrical components in water.

My fan is not working, what should I do?

First check the fuse or circuit breaker. Make sure the motor cord is securely plugged into the receptacle. Also check the switch wiring. If the problem persists, contact customer service.

The fan is making abnormal noise, what are possible causes?

Abnormal noise may be due to a loose motor or a fan blade rubbing against the housing. Cut power, remove the grille, and check that all screws are tight. If noise persists, call a professional.

Airflow is weak, how to improve?

Check for obstructions in the duct (bird nests, etc.). Make sure the duct is as short and direct as possible. A larger duct can also improve airflow.

1. Choose the location for your fan. To ensure the best air and sound performance, it is recommended that the length of ducting and the number of elbows be kept to a minimum, the radius of each elbow be as large as possible for the installation, and that insulated hard ducting be used. Larger duct sizes will reduce noise and airflow restrictions.
2. Select the most convenient electrical knockout and remove using a straight-blade screw driver (Figure 2).
3. No additional vibration deadening materials are needed for this fan.
