CLEANING & MAINTENANCE

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 blower assembly (includes motor and impeller).

OPERATION

Use an on/off switch to operate the fan.
Refer to Brogan’s catalog for a complete line of accessories/controls to effectively adapt these fans to your requirements.

IMPORTANT – The ducting from this fan to the outside of the building has a strong effect on the air fl ow, 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.

OPTION – To mount housing anywhere between ceiling framing: Use optional Hanger Bar Kit (sold separately from local distributors or website). Follow mounting instructions included with kit.
