Once the location is marked, the hole should be cut using a drywall saw or a similar tool. The drywall cover board should be temporarily placed over the opening to provide access during the installation process.
The ducting must be routed from the fan to the exterior of the building. The duct should be as short and straight as possible to maximize airflow efficiency. Insulation can be added around the duct to reduce energy loss and prevent mold growth. It is important to ensure that the duct is properly sealed to prevent air leaks and maintain the effectiveness of the ventilation system.
2. Mounting the Fan Housing
Once the ceiling opening is prepared, the fan housing can be mounted. The short and long flex brackets included in the package should be used to secure the housing in place. The fan housing is designed to be installed from the attic side, while the motor and grille are installed from the room side.
To mount the housing, align the duct connector with the tabs on the housing and secure it in place. The fan motor should then be placed into the housing and secured using the provided screws. The wiring compartment must be carefully checked to ensure that all wires and terminals are properly connected and secured.
3. Connecting the Electrical Wires
Proper electrical connections are essential for the safe and effective operation of the fan. The wiring must be connected according to the manufacturer's specifications and in compliance with local electrical codes. The fan must be connected to the grounding conductor of the supply circuit to ensure electrical safety.
