Step-by-Step Installation Guide

Step 1: Pick the Right Spot
Place the diffuser near the supply duct of your HVAC system (after the return/filter) for best scent flow.

Step 2: Plug It In
Connect your diffuser to a power outlet using the adapter provided.

Step 3: Fill the Bottle
Unscrew the fragrance bottle inside the unit, fill it with your chosen scent oil, and screw it back in tightly.

Step 4: Connect the Tubing
Insert one end of the clear tubing into the diffuser's mist outlet (where the scent is released).

Step 5: Insert Tubing into Your Duct

Carefully create a small hole in your HVAC supply duct using a screwdriver.
Measure and cut the tubing to fit — insert only 1 inch into the duct.
Make sure it enters at a 90° angle with no loops or bends.
Secure the tubing to the duct using HVAC-grade tape.

Step 6: Power On & Adjust
Turn on your HVAC system and diffuser. Use the touchscreen on the diffuser to adjust scent intensity to your liking.

Maintenance Tips

Refill fragrance oil as needed.
Clean the diffuser regularly to prevent clogs (refer to your manual).
To remove the tubing, press and hold the black ring on the connector and gently pull the tube out.
