Air Diffuser Pro Installation

Prep the Diffuser

• Fill the oil canister to the clearly marked fill line. Do not overfill.
• Tighten the canister cap securely, then insert it into the machine.
• Power on the unit and confirm it starts with the default cycle: 10 sec on / 120 sec off.
• Optionally, pair the unit via the Scenta companion app (also called Art Diffuser).

Drill Into the HVAC Duct

• Locate the supply (cold air) duct. This carries conditioned air into your rooms.
• Using a 7/16" drill bit, carefully drill a single hole into the duct wall.
• Hold your hand near the hole to verify airflow is present.

Insert the Diffuser Tube

• Push the provided tube firmly into the drilled hole. The tube is designed to create an airtight fit.
• Angle the tube so it points with the direction of airflow inside the duct.
• Ensure the rubber stopper sits flush and snug against the duct surface.

Place the Unit and Connect

• Set the Air Diffuser Pro on a flat, stable surface near your HVAC system.
• Push the free end of the tube into the diffuser's quick-connect port until it clicks.
• Plug the diffuser's power cable into a nearby outlet.
• For automation, use a smart plug between the diffuser and the outlet.

Test the System

Turn the unit on and run through this quick checklist:

• No air leaks at the duct connection
• Diffuser pump is running (you'll hear a soft click)
• HVAC is distributing scent through your home's vents

Optimize (Optional)

Use the Scenta app (also called Art Diffuser) or the buttons on the unit itself to fine-tune your experience:

• Sync with HVAC fan: Run the diffuser only when the fan is active for maximum efficiency.
• Schedule scent bursts: Set specific times like mornings or before guests arrive.
• Reduce oil waste: Shorten on-cycles or increase off-intervals to conserve oil.
