Installation Guide
Mounting Options
The L700 ventilator fan can be installed in either a ceiling or a wall. Ensure the mounting location provides adequate structural support for the fan's weight (approximately 33.4 pounds) and allows for proper ducting to the outdoors.
Ducting Considerations
The fan features a 41.5" x 18.5" metal duct connector. The duct can be configured for horizontal, vertical, or in-line discharge. A separate adapter may be required for in-line configurations. It is recommended to use a 10-inch diameter duct for optimal performance and to minimize static pressure loss. Ensure all duct connections are sealed properly to prevent air leakage.
Electrical Wiring
The fan operates on 120V AC power. All electrical connections must comply with local codes and the National Electrical Code (NEC). Consult a qualified electrician if you are unsure about wiring procedures.
Operating Instructions
The Broan-NuTone L700 ventilator fan is designed for straightforward operation. Once properly installed and wired, the fan is controlled via an external wall switch (not included). Press the switch to turn the fan ON or OFF. The fan's permanently lubricated motors and automatic backdraft dampers ensure continuous and quiet operation when activated.
Care and Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your ventilator fan.
- Cleaning the Grille: The fan grille can be removed for cleaning. Wash the grille by hand with mild soap and water. Rinse thoroughly and allow it to dry completely before reattaching.
- Motor Maintenance: The fan motor is permanently lubricated and does not require additional oiling.
- Ductwork Inspection: Periodically inspect the ductwork for any obstructions, leaks, or damage. Ensure that the backdraft dampers operate freely.
Always disconnect power to the fan at the service panel before performing any cleaning or maintenance.
