**Packaged units are systems where the air handler and the air conditioning compressor are built together and are installed outside of the building. GENERAL INFORMATION The UV-Aire unit uses technology that is recommended by doctors who state that "ultraviolet radiation, properly integrated with heating, ventilating, and air conditioning systems, shows the most promise as a widely applicable means of air disinfection".1 Optional UVC-Light Shield: Designed to mount at virtually any angle to guard or shield certain plastics, Optional UVC-Light Shield wiring or air filters that may be affected by UVC light. WARNING: Never expose eyes or skin to UVC light from any source. Looking directly at the UVC light may cause permanent eye damage or blindness. Never operate the UV-Aire™ Air Purifying System out of the plenum. Avoid touching the glass portion of the lamp with your hands. page 2 page 3 WARNING: Never expose eyes or skin to UVC light from any source. Looking directly at the UVC light may cause permanent eye damage or blindness. Never operate the UV-Aire™ Air Purifying System out of the plenum. Avoid touching the glass portion of the lamp with your hands. INSTALLATION 1. Locate a suitable location for the unit downstream from the 'A' coil in the supply plenum or in the return plenum; preferably downstream from the air filter. For optimum "cleaning" effect on the 'A' coil, mount the unit in the supply plenum as close as possible to the 'A' coil. (See Figure 1) CAUTION: Investigate and determine the location of the A coil prior to drilling holes in duct for mounting unit. NOTE: For duct board installation, refer to enclosed bagged assembly containing mounting plate and instructions. 2. Apply supplied mounting template to air duct in either a vertical or horizontal position. (See Figure 2) Leave template mounted to duct for future reference. 3. Drill 1.8" diameter mounting holes at positions indicated on template. (See Figure 3) 4. Cut out the large opening (1-1.2" hole) on the template. (See Figure 3) 5. Using a 1.4" to 1.2" drill bit, drill a viewport hole as indicated on the template. (Figure 3) 6. Optional Light Shield: The light shield may be mounted at virtually any angle. However, when deciding on a suitable location, the mounting screw head can not be in the shaded area of template. (See Figure 4 to view areas to avoid.) Figure 1 Figure 3 Figure 2 Figure 4 Head of mounting screw CANNOT be located in shaded area. Notes: • For applications with multiple systems, we recommend one unit per system. • For larger applications, multiple units are recommended. Contact technical support at 1-252-522-3031 for sizing. • Each unit will require its own transformer.

Looking directly at the UVC light may cause permanent eye damage or blindness. Never operate the UV-Aire™ Air Purifying System out of the plenum. Avoid touching the glass portion of the lamp with your hands. 7. Press shield onto duct wall then secure with screws. (See Figure 5) 8. Attach the UV-Aire mounting base onto the plenum with the supplied sheet metal screws. (Refer to template as shown in Figure 3) This must be tight in order to activate the built-in safety switch. NOTE: DO NOT remove template from duct. 9. Do not handle the lamp with bare hands. Oils on your hands tend to reduce lamp intensity. Install lamp into ballast. (See Figure 6) 10. Wipe off the lamp glass with the supplied alcohol wipe. Then insert the lamp through the center hole of the mounting base. (See Figure 7) The power cord must be 90° to the viewport hole on the mounting base. 11. With the ballast pressed against the mounting base, rotate the ballast clockwise 90°. 12. Do not wire the unit into the appliance's 24 volt fan or thermostat circuit. Premature failure of the ballast and lamp will occur. The warranty will be voided. Do not wire into a standard 120VAC electric supply. Wire according to Diagram A or Diagram B. Unit is designed to be wired to a 24V/40VA power supply only. Check lamp operation by looking through the viewport hole. NOTE: The viewport hole is made of glass and will not allow any UVC rays to pass through. A blue glow should be seen in the duct. 13. If blue glow is not seen, make sure the base is properly installed onto duct. There is a proving switch located on the base that needs to be seated properly onto the duct. Make sure when installing the base the plated washer on the switch is raised approximately 3.16". The proving switch must be fully engaged. (See Figure 8) 14. With aluminum or foil tape, seal all joints and seams of the plenum near the mounting location to reduce any direct viewing of light.
