Connecting the Diffuser to HVAC.
Refer to the Air Stream Duo HVAC Connection Diagram FIG A.
The Air Stream Duo is a versatile and powerful commercial HVAC system scent diffuser.
Diffusing the scent via HVAC will allow you to cover multiple rooms and zones. To scent the
right zones, check with your HVAC provider or Mechanical Engineer to determine which
HVAC unit to connect to.
The Air Stream Duo can cover 15,000 sq.ft. of space.
1. You need to choose the air handler you want to connect to. If you have multiple air
handlers, select the one that will cover the area you wish to be scented. Consult your
HVAC supplier if needed.
2. With a metal drill bit designed to drill through sheet metal, drill a 7/8-inch hole in the air
duct directly after the blower. Make sure you are tapping into the supply side of your
duct, not the return side.
3.
IMPORTANT:
Never install before the coils or filters as the filters will dilute the scent
and you will not get the same result.
4. Once the 7/8-inch hole is made, insert the hose guide. The hole on the end of the hose
guide should be pointing with the air flow not against it. This allows the scent to travel
in the same direction as the air flow.
5. Secure the hose guide by screwing it to the duct.
6. Screw the supplied HVAC adaptor into the hose guide.
7. Take a second HVAC adaptor and screw it into the Air Stream Duo.
8. Either wall mount the Air Stream Duo to the duct, the wall or place on a shelf directly
under the Scent Point connection. It’s important to keep the Air Stream Duo as close as
possible to the scent point. MAX. AIR TUBE LENGTH SHOULD BE 3 FEET.
9. Cut supplied air tube to the correct length to go from the Air Stream diffuser.
The distance between the Air Stream diffuser and air tube should be as short as possible.
MAX. 3 FEET. Do not leave any slack. Coiling or excess air tube will create air
pockets and buildup of scent inside the tube.
10. Connect the AirStream Duo to the 110V-240V plug and set the timer.
