AromaTech 20250729 SIngle BT Diffuser

Welcome to

Pure scent — and nothing else.
Our cold-air diffusers disperse scent using filtered air instead of water or heat. The result: a cleaner, more consistent scent experience.

Powerful.
Our cold-air diffusers cover twice the square footage of ultrasonics or candles.

Consistent.
Long-lasting fragrance is evenly distributed throughout your home.

The Magic of Nebulization

What is Cold-air Diffusion?
Cold-air diffusers disperse fragrance oils through nebulization—a process that breaks down scent oils into an ultrafi ne dry mist. The nanoparticles in this mist are so tiny that they remain suspended in the air for hours. This cutting-edge technology uses no water, alcohol or heat, diffusing scents in their purest form.

Why is it Better?
Cold-air diffusers can cover spaces twice as large as typical candles, reed diffusers, plug-ins and ultrasonics. They’re more consistent, ensuring fragrance is evenly distributed, and more precise, giving you the option to adjust the scent intensity. Our diffusers are cleaner because they neither dilute nor heat the scent oil.

Cold-air Versus Ultrasonic
No water, no mold—our cold-air diffusers have a number of benefi ts over traditional ultrasonics. They’re more powerful and use diffuser oils more effi ciently, so your scents last longer. They’re also far easier
to use, you can go months between refi lls and no hands-on cleaning is required. In fact, a quick rinse with our cleaning solution is the only maintenance recommended.

Our Ingredients
We’re very particular about what goes into our diffuser oils—and what stays out. To craft the safest, purest and most beautiful scents, we use a mix of safe synthetic and naturally derived ingredients. All of our diffuser oils are sustainably sourced and made in the U.S.

Our Safety Promise
Our diffuser oils exceed the strict safety and environmental standards set by the International Fragrance Regulatory Association (IFRA), as well as the Volatile Organic Compound (VOC) guidelines set by the California Air Resources Board. They are entirely free of parabens, sulfates, synthetic colors and other harmful additives. Please note that our oils are for diffuser use only; do not use topically or ingest. Those with medical conditions should consult a health care practitioner prior to use.

To set and edit schedules:

Continue editing each schedule until you’ve found the perfect set of schedules for your space and desired scenting experience.

Scent Intensities & Schedules

The intensity level can be adjusted from level 1 (MIN) to 10 (MAX). Start at level 1 and work your way up as needed.

Wall Mounting

You will require the following tools:

1. Bubble level
2. Drill and drill bit
3. Hammer
4. Screwdriver

Step 1.
Use the Mounting Bracket as a template to mark the locations of the holes on your wall. Drill holes in the wall using a drill bit that matches the size of the dry wall anchors.

Step 2.
Insert the drywall anchors. Using a hammer, tap the end of the wall anchors lightly to fully insert them in the wall.
Fix the Mounting Bracket to the drywall anchors with the provided screws.

Note: A set of nails is also provided as alternative Mounting Hardware.

Step 3.
Place the Oil Drum on the Mounting Bracket
Repeat steps 1-3 to wall mount a second Oil Drum.

WARNING: Always make sure the Oil Drum is sitting upright.

HVAC Connection

Before beginning to install your Air Stream® BT ensure the Air Handling Unit (AHU) does not use an open gas flame.

You will require the following tools:

1. Drill and drill bit the size of the Hose Guide
2. Scissors or exacto knife

Air Stream® BT HVAC Connection Diagram (Figure A)

Use Figure A as a general reference when connecting your Air Stream® BT to your HVAC system.

Step 1.
Identify the area in your space you’d like to scent and locate the ductwork and AHU the space connects to.

Step 2.
Identify the Scent Point. This is the optimal location within the ductwork for dispersing the scent and where you’ll insert the Hose Guide.

WARNING: Open gas flames must be avoided.

Ideal Locations:

• After the air output from the AHU.
• After the cooling coils and filters. Never install before the coils or filters as the filters will dilute the scent and you will not get the same result.
• Directly in the duct that supplies air to the room you’re scenting.
• Ensure the Scent Point is near a power outlet where you can plug in the Air Stream® BT.

See Figure A for a visual representation of the Scent Point.

Step 3.
Using a metal drill bit, drill a hole in the ductwork at the Scent Point to match the size of the Hose Guide.

Step 4.
Screw one HVAC Adapter to the Diffuser Head.

Step 5.
Screw the other HVAC Adapter to the end of the Hose Guide.

Feed the right-angle end of the Hose Guide into the Scent Point hole you just drilled. Point the Hose Guide in the direction of airflow, and fix in place.

Note: Apply Teflon Tape to the HVAC Adapter threads as required.

Step 6.
Place the Oil Drum directly under the installed Hose Guide. The ideal distance between the Hose Guide and the Diffuser Head is 12” to 15”, never more than 3 ft. Use the provided Mounting Bracket if required.
Connect the 6.5 mm Hose between the Diffuser Head and the Hose Guide by pushing the ends into the HVAC Adapters. Use scissors or an exacto knife to cut the hose to the required length.

Ensure the 6.5 mm Hose slopes upwards and there is no sagging where liquid could build up.

Note: If you need to disconnect the 6.5 mm Hose, push down on the HVAC adapter collar while pulling the hose out.

Ensure the Oil Drum is sitting upright.

Step 7.
Connect the 4 mm Hose between the Diffuser Head and the Air Stream® BT.

Step 8.
Plug in your Air Stream® BT and set schedules in the App or manually.

Repeat steps 3-7 to connect a second Oil Drum.

Scenting

Explore the possibilities of scenting by changing the scent you use. Choose a cozy scent for the weekend and an uplifting scent during the week. Mark a special occasion or a party by choosing a scent that’s celebratory and fun.

Changing the Scent

Whether you like to redecorate your space to match the season or your mood, home scenting is a simpler and faster way to update your home or office.

When scenting for the season opt for a scent that invokes the spirit of each season. Choose a revitalizing scent that is fresh, fl oral, or tea-infused. For sun-drenched summer days, a fragrance that contains fresh citrus scents and hints of coconut and sea air is recommended. During the fall a scent that contains woody and gourmand notes can create a cozy atmosphere. Switch to a rich scent fi lled with vanilla, cinnamon or tonka bean that matches the festive energy through the winter.

You can even change your scent throughout the day. Choose an invigorating scent to encourage productivity and a relaxing scent for downtime. Choose a nostalgic scent for family time and a glamorous fl oral for celebrating. It’s easy to see how refreshing your space is easy with home scenting.

Maintenance

We recommend cleaning your diffuser every 2 months or when you change your oil.

1. Empty out any remaining oil in the Oil Drum.
2. Pour a quarter inch of AromaTech Diffuser Cleaner into the empty Oil Drum, reassemble the diffuser parts and run on the highest intensity setting for 15 minutes.
3. Discard the used diffuser cleaner. Fill with your favorite AromaTech oil and enjoy.

Troubleshooting

My diffuser display is locked.

To unlock the display, simply press and hold the SET button for 5 seconds.
The display will automatically lock and turn off after 1 minute if not used.

My diffuser isn’t turning on.
Check to make sure the Power Adapter is correctly plugged into the DC power jack and the electrical source.
If the hours of operation timer is set incorrectly and you are trying to diffuse during the time that the machine is programmed to be off, the Air Stream® BT will not scent.

My diffuser is making a gurgling sound.

It’s likely that you’ve overfilled the Oil Drum. Simply pour out some of the oil in the Oil Drum. Be sure to only fill to the shoulder of the Oil Drum and not to the very top.

Diffuser is running but no mist is visible and/or cannot smell the scent.

This may be for the following reasons:

• Your unit needs to be cleaned. To clean your diffuser replace the oil with diffuser cleaner and run on its highest setting for 15 min.
• You’ve run out of oil. Refill the Oil Drum.
• The Oil Drum is not sealed. Make sure the Diffuser Head is screwed in firmly.

The oil in my diffuser looks cloudy.
This is normal and will have no effect on diffusion. The nebulizer will aerate the oil in the Oil Drum which might cause it to appear cloudy.

My diffuser is dirty, how do I clean it?
To remove smudges use mild soap with water on a microfibre or soft cloth to wipe clean.
