Scenting via HVAC System
Installation for HVAC System Scenting
Operation
The AirQ generates micro-droplets 1/100th the diameter of a human hair from a reservoir of liquid in a
disposable cartridge. These micro-droplets behave like a vapor. They are passed through a silicon tube and
injected into the airflow of the air handler using an injector tube that is installed in a hole in the ductwork.
The micro-droplets blend with the air in the ducting to deliver a uniform effect throughout the area served.
The AQ550 device with HVAC kit incorporates an Airflow switch, a sensor tube, an injector tube, a fragrance
supply tube and duct-mounting detailing within a unitary molded housing.
Airflow Switching
The AirQ 550 with HVAC kit is operated only when the fan or blower is operating to ensure uniform, even
distribution. To make this possible a 12V airflow switch is provided.
Determining the Location of Airflow Switch
The airflow switch should be mounted vertically on the side of the air duct at a convenient location and
downstream from the furnace. Caution: Do not mount airflow switch on return side. The airflow switch and
the female connector on the lower right side of the AirQ appliance should be less than 5 feet apart. The
hose run to the Sensor Tube should be as short as possible and less than 1 foot.
