Can cause severe burns. Disconnect power 15 minutes before removing ultraviolet bulb(s). INSTALLATION Turn off power to air handler before installation. Choose a location for duct-mounting the handle that will allow maximum exposure to the coil, drain pans and internal surfaces of the air handler. The adjustable mounting bracket can be used to angle the bulb to fit in tight applications and to maximize exposure. Ballast can be mounted in the control panel of the air handler or outside of the duct when mounted in a weather-protected space. Make sure to mount ballast within reach of handle so 6-foot cord will reach. d right on the Fig. 2. Direct mount to internal surface. For angled mounting, adjust the mounting bracket to the desired angle and fix in place with bolt. Use mounting screws to mount the handle to the bracket. Use self-tapping sheet metal screws to mount the bracket in the desired location. 68-0297EFS—05 UV100RM TRUEUV™ COIL TREATMENT SYSTEM UV100RM TRUEUV™ COIL TREATMENT SYSTEM M27084 SURFACE OF AIR HANDLER ADJUSTABLE BRACKET Fig. 3. Angled mounting bracket mount to internal surface. Attach shield to bulb in such a manner as to direct UV-C light away from access panel for secondary safety to prevent direct exposure to light. M27062 from location of handle to ballast location. Use grommet to seal hole around cord. M27079 Fig. 5. Connect cord from handle to ballast location. Attach base to handle. Base should be used for internal mounting applications as it activates an internal safety switch in the handle. Snap bulb into handle. M27060 Fig. 6. Attach base to handle. Adhere Safety Precautions/Template sticker outside of the duct near the access panel or near the location of TrueUV and write Fig. 4. Attach shield to bulb. the location of the ballast (switch) on the sticker. 68-0297EFS—05 4 UV100RM TRUEUV™ COIL TREATMENT SYSTEM 5 68-0297EFS—05 Fig. 7. Apply Safety Precautions/Template sticker to outside of duct. External Mounting Adhere Safety Precautions/Template sticker in chosen location. Drill 1-9/16–inch hole for bulb. Mount base using selftapping screws. Snap bulb into handle and twist onto base. Fig. 8. Apply Safety Precautions/Template sticker to chosen location. Shield can be used to direct UV-C away from susceptible materials such as media filters. Fig. 9. Use shield to protect media filter. Mount ballast in chosen location. If necessary to penetrate barrier, drill 3/4-inch hole to run cord. Use grommet to seal hole around cord. See Fig. 5. Mount Indicator Window The indicator window allows you to safely check the operation of TrueUV. It can also indicate to you when TrueUV has been turned off and service or maintenance can safely be M27080 9 16 9 16 9 16 M27081 M27072 UV100RM TRUEUV™ COIL TREATMENT SYSTEM 68-0297EFS—05 6 performed. Choose a location where the indicator window will show UV operation from the location of maintenance or service access. Drill 1/2-inch hole. Snap indicator window into hole. Place a maintenance warning label next to the indicator window. Other maintenance warning labels should be placed at access and service panels where they can be easily seen during any future maintenance or service. Fig. 10. Indicator window and label. WIRING Ensure power is turned off to the air handler before proceeding. Connect the 24V leads of the ballast to the 24VAC transformer. 18 gauge wire can be used to extend leads if necessary. There is no polarity to TrueUV and either lead can be wired to 24V hot and common. Fig. 11. Wiring diagram. CHECKOUT . Close all access panels and turn power on to HVAC equipment. . Turn ballast switch position to ON or CYCLE. . Check TrueUV operation through indicator window. Do not attempt to look directly into the duct to see the illuminated ultraviolet bulb. . Installer should orient the homeowner to the unit by showing them the blue glow from the indicator window which indicates the unit is working. . The installer should also emphasize the hazard warnings so that homeowner knows how to safely inspect and maintain their system. MAINTENANCE WARNING UV Light Hazard. Harmful to bare skin and eyes. Can cause temporary or permanent loss of vision. View illumination only through lamp light indicator on lamp handle. To prevent exposure to ultraviolet light, disconnect power to ultraviolet system before servicing any part of heating and air conditioning system. Do not mount device in location that allows ultraviolet light to be seen after installation. Bulb cleaning is recommended quarterly as routine maintenance. Keeping dust off the bulb will keep the UV-C intensity high and maintain the kill rate of TrueUV. Use a damp cloth to wipe bulb clean. Bulb should be replaced every year if using the ON position or every 2 years if using the CYCLE position. 1.
