2 Diffuser Installation

Step 1
Locate the HVAC Quick Connector piece and the sealing tape included within the Haus Diffuser packaging.
​
Wrap the sealing tape around the thread of the HVAC Quick Connector 3-5 times to prevent air leakage.
​​​
Step 2
Screw the HVAC Quick Connector onto the Haus Diffuser.
Note: You will need to remove the silver nozzle at the top of the machine. This nozzle is there incase you do not want to scent via your HVAC and simply want the scent to disperse from the top of the machine.
​​
Step 3
Once the HVAC Quick Connector is secured to the top of the equipment, press down on the quick connector and insert the fragrance tube (included in the Haus Diffuser packaging) into the Quick Connector.

Step 4
Insert the fragrance tube into the air conditioning duct (after the coils) and secure with duct tape.
​
Note: Do not insert the fragrance tube into your equipment before the coils. Our fragrances are only designed to disperse into the air ducts to scent through air vents that are serviced by those ducts.
Step 5
To install the fragrance canister, pull open the magnetic panel on the front of diffuser to insert the fragrance oil canister.
​​
Step 6
Screw the fragrance canister into the diffuser and tighten so that it is secure.
​
Note: Keep the equipment vertical at all times when a fragrance bottle is installed to prevent leakage.
Step 7
Reattached the magnetic panel to the front of the diffuser
