ROOMSIDE SERIES AR80MB
The ROOMSIDE SERIES AR80MB is a fan and light combination unit designed for installation in residential spaces. It provides quiet and efficient operation, long life, and an attractive appearance. The fan features a permanently lubricated motor that never needs oiling. The unit is equipped with a blower assembly that includes the motor and impeller.
This product is suitable for use in various rooms of the house, excluding cooking areas. It is important to ensure proper installation and maintenance for optimal performance.
Cleaning & Maintenance
To maintain the performance of the fan, it is recommended to remove the grille and vacuum the interior of the unit using the dusting brush attachment. The motor does not require oiling, but if excessive or unusual noises are heard from the motor bearings, it is advisable to replace the blower assembly.
Operation
The fan and light can be operated using separate switches. An on/off switch or speed control can be used to operate the fan, while a separate switch is needed for the light. Refer to the Wiring Diagram section for detailed instructions.

ALL INSTALLATIONS
Start here.
IMPORTANT – The ducting from this fan to the outside of the building has a strong effect on the air flow, 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.
