UV Diffusers Installation and Operation Manual
2. Secure the conical collar to the plenum with self-tapping metal screws.
IMPORTANT: UV Diffusers must be installed using the supplied conical collars to ensure security and
performance of the product. Do not use other collars or adapters.
3. Lay the diffuser in the false ceiling or auxiliary frame.
4. Secure the four earthquake tabs to the building structure using threaded rods or metallic cables (not supplied).
5. Connect duct to the round part of the conical collar. Secure the assembly and make sure there is no air leakage. In
order to ensure zero leakage, it is recommended to seal the duct connection as well as the plenum box's edges
with UL certified aluminum duct tape.
IMPORTANT: A. Product should not be installed within a direct line of sight to any plastics or polymers not previously
evaluated suitable for UV exposure. B. Product should not be installed with a direct line of sight to any opening that
may expose the user or serviceman to UV exposure within 4 meters (158in). Any service panel or opening in the air
handling circuit that would expose the user to direct UV contact should utilize a provided interlock.
