UVL-COIL Ultraviolet Lamp Kitsfor AHU CoilsPRODUCT DATAFEATURES UV-C light irradiates coil & air handler interior, killingmold, bacteria and viruses Scalable design allows wide variety of multi-lampconfigurations High quality water-resistant lamps Mounts using off-the-shelf ½ inch EMT conduittubing Includes 10 foot cable & all mounting hardwareexcept ½ inch EMT conduit Saves energy by keeping components cleanerAPPLICATIONThe system is designed for installation into commercial airhandling units for the purpose of surface disinfectionusing ultraviolet germicidal irradiation. For maximuminstallation flexibility and cost-effectiveness, the UVlamps are mounted onto a framework of standard ½ inchEMT tubing (not included). The remotely mounted weatherresistant power supply can withstand the wet environmentfound inside of air handlers or the exposed conditions ofoutdoor packaged air conditioning systems. The numberand placement of lamps is determined by the coildimensions.ContentsAPPLICATION .FEATURES .SPECIFICATIONS .PLANNING THE INSTALLATION .ORDERING INFORMATION .INSTALLATION .WIRING .MAINTENANCE .TROUBLESHOOTING .11232566731-00402-02

Vertical Support Configuration.UV Lamp Configuration Guidelines Maximum germicidal effectiveness is within an 18 inchradius from UV lamp center axis. The optimal distance between UV lamp(s) and theirradiated surface is 12 inch. The distance between stacked UV lamps should notexceed 36 inches. The distance between end to end UV lamps should notexceed 12 inches. The distance of UV lamp ends to the edge of irradiatedsurface should not exceed 10 inches. The spacing guidelines above may not apply for allapplications. Use recommendations in Table 2 to selectappropriate kit based on coil size.Fig. 2.

Electrical Connections.Mount Power Supply(s)Mount the power supply in a location (inside or outside ofthe HVAC system) that is convenient for access to the mainpower supply and for connection to the UV lamps. Thepower supply is weather resistant and is suitable formounting inside or outside of the air handler.Connect Lamps and CablesArrange cables as needed for installation. If necessary, usecable strain relief fittings or other means to pass cablesthrough the cabinets or air system walls. When UV lamps,power supplies, and cables are in place join the lamp andpower supply cables by aligning the electrical pins andflanges on the rubber connectors and pushing them firmlytogether.Use the supplied self-taping sheet metal screws to mountthe power supply in place through the mounting holes onthe sides of the base. It is recommended to use wire boxes,cable strain relief fittings, or other sealing methods in orderto pass the power cord and lamp cables into the interior ofthe air handler for connections.Align Pins & Lamp KeySight Glass InstallationLamp KeyThe sight glass allows safe viewing of the UV light systemwhen in operation. Find a suitable location such as a doorto the HVAC system for the sight glass. Drill a 1” hole andpress the base of the sight glass through it.V LampUVPush Firmly TogetherPower SupplyCableFig. 11.

Unlike SoftQuartz, these lamps do NOT need to be wiped of grease orother contaminants, and are NOT affected by humidity.They are warranted for 2 years of UVC output, to 60% oftheir original output. Sizing guidelines are based on theend of lamp life output levels.WIRINGWARNINGElectric Shock Hazard.Can cause personal injury.Turn off main power before making electricalconnections.Honeywell UV lamps are rated for two years germicidaleffectiveness. The visible blue light will continue toilluminate, but does NOT have any germicidaleffectiveness. Bulbs must be replaced on schedule for thesystem to function properly.Refer to electrical diagram (Fig. 10.) for proper connectionsof the power supply to the main power.31-00402—02IMPORTANTUse only Honeywell replacement lamps.
