Installation:
Designed for use with Panasonic WhisperLine inline fans (e.g., FV‑10NLF1, FV‑20NLF1). Position the 6″ and 4″ grilles in ceiling or wall openings using the provided clamps. Install backdraft dampers and connect both ducts to the inline fan using the included Y-adapter. Tighten all clamps securely and restore fan operation, checking for airtight duct connections and proper damper function.
Maintenance:
Inspect grilles and dampers monthly for dust buildup. Clean with a soft brush or damp cloth. Ensure both dampers open and close freely to maintain optimum airflow.
