Step 1: Open the device
Carefully lift the diffuser head out of the device. This is the top part with the atomizing module and the connection point for the bottle. Place the device on a flat surface so it doesn't tip over during setup.
Step 2: Remove the oil reservoir
Unscrew the bottle from the diffuser head. This is the 120 ml bottle included by default. Check that the bottle is clean before refilling it.
Step 3: Fill the reservoir with your aroma oil
Fill the bottle with a maximum of 120 ml of aroma oil. Preferably use Scentech oils, since their viscosity (<30 mPa.s) ensures optimal misting. Screw the bottle firmly onto the diffuser head to prevent leakage.
Step 4: Put everything back into the device
Slide the diffuser head with the filled reservoir back into the diffuser. Make sure everything is placed straight and connects properly. If parts aren't tightened properly, the scent may weaken or oil may leak.
Step 5: Always keep the diffuser upright
From the moment there's oil in it, the device must always stay upright. A tilted diffuser can let oil run into the atomizer, which can cause malfunctions or noise and can damage the electronics.
Step 6: Close the device
Check that the device is closed correctly. Press the top down firmly so no air escapes and the device can mist optimally.
Step 7: Choose your power source
The A326 Pro Diffuser runs on a built-in lithium battery or on mains power.
• With battery power, the device is fully wireless and sits more neatly in your interior.
• With the adapter, the diffuser runs continuously as long as it has power.
Check that the 12V-2A adapter is connected correctly if you choose mains power.
Step 8: Pair it with the Scentech app
Download the Scentech app (purple logo) from the App Store or Google Play. Turn on the Pro with the on/off button, turn on Bluetooth on your phone, and open the app. Your Pro will appear under Nearby as Smart Aroma Diffuser Pro. Then choose a room, the scent, a schedule and the intensity. Full instructions are in Installing the Scentech app and adding your diffuser.
Step 9: Set the timer button to Smart
Set the timer button on the Pro to Smart, so it follows the schedule from the app. On 1H, 2H, 4H or 8H, it runs for that time via the button.
Step 10: Ready to use
Your Pro now works automatically according to your schedule, even when the app is closed. Want different times on weekends? Choose a different schedule or create custom times: see Setting up a schedule.
Frequently asked questions:
• "How do I prevent leakage?" → Always keep the diffuser upright and screw the bottle on firmly.
• "Why can I barely smell the scent?" → Increase the intensity by one level in the app or check that the atomizer is clean.
• "How do I reconnect?" → Hold the on/off button for 5 seconds (factory reset) and add the Pro again in the app.
• "It sprays non-stop after setting a schedule?" → See Pro sprays non-stop or the schedule doesn't come through.
