Setup and Installation
Pre-Installation Check
Before permanent installation, connect the fan to power using the included test cord cap to verify that it functions correctly. This allows you to test the fan and light features.
Remote Control Pairing
The remote control requires two AAA batteries (not included). To pair the remote with the fan, refer to the specific pairing instructions located on the back of the remote control unit.
Installation Steps
- Prepare Ceiling Opening: Use the provided cut-out template to mark and cut an 11.37 x 12.12 inch opening in the ceiling.
- Connect Ducting: The fan is designed for 6-inch diameter ducts. Connect the fan's exhaust port to a 6-inch duct (aluminum foil duct included). Ensure a secure and airtight connection.
- Mounting Options:
- Direct Joist Mount: If installing directly to a ceiling joist, secure the fan housing using appropriate expansion screws.
- Adjustable Bracket Mount (Flex Bracket): For installations between joists, use the expandable mounting bracket. This bracket adjusts to fit joist spacing between 12-22 inches. Secure the bracket to the joists, then attach the fan housing to the bracket.
