**Packaged units are systems where the air handler and the air conditioning compressor are built together and are installed outside of the building

INTERNAL MOUNT INSTALLATION INSIDE PLENUM OR AIR HANDLER

Choose a suitable location for the lamp in the supply plenum, return plenum, or air handler; preferably downstream from the air ﬁlter. For optimum “cleaning” effect on the A coil, mount the unit above or below the A-coil as close as possible while still illuminating the entire surface of the coil. (See Figure 1)
Clean the mounting surface with degreaser and let dry. The mounting surface must be clean and dry.
Attach the Shield to the Mounting Bracket Assembly, if it is to be used. (See Figure 2)
Attach the Lamp to the Mounting Bracket Assembly. (See Figure 3) Loosen the clamp bracket nut, inserting the lamp through the hole, swivel the clamp bracket fully back over the ﬂange of the lamp base, and retighten the clamp bracket nut.
An #8-32 wing nut is supplied that may be used for internal applications only.
Remove tag and alcohol swab from the lamp, and clean the lamp glass with the alcohol swab. Avoid touching the cleaned lamp with your hands.
Attach the Mounting Bracket Assembly to the mounting surface using the magnet.
If the mounting surface is insulated, slit the insulation, insert the magnet through the slit, draw the insulation back over the magnet and bracket surface, and tape closed using metal tape or other means that would not be affected by UVC rays.
Some surfaces may be inadequate for mounting with the magnet (rough, uneven, heavy paint etc.). The magnet may be removed from the Mounting Bracket Assembly, and the bracket assembly attached to the mounting surface with included self-drilling sheet metal screws or other appropriate fasteners. Holes are provided on the bracket assembly for this purpose. Use care to avoid equipment damage to concealed wiring and other components when installing fasteners.
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™ AirPurifying System out of the plenum. Avoid touching the glass portion of the lamp with your hands.
If desired, loosen the wing nut on the bottom of the Mounting Bracket Assembly (see Dimensional Drawing), and swivel/extend the lamp bracket to position the lamp in the desired position, and retighten the wing nut securely.
CAUTION: MAKE CERTAIN THAT POWER HAS BEEN DISCONNECTED TO THE HVAC SYSTEM, AND THE 24 VAC TRANSFORMER POWER SOURCE, BEFORE PROCEEDING WITH THE INSTALLATION!
Mount the installer-supplied 24VAC transformer (not included) in an area protected from the lamp, using the included sheet metal screws or other appropriate fasteners, and connect to 120V power source. Observe all local and national electrical and mechanical code requirements regarding 120 V wiring.
NOTE: It is recommended that the 24V ballast power source be wired through a safety disconnect switch, such as a door switch, that will disconnect power to the transformer if the access panel to the UVC lamp installation area is removed (see Wiring Diagram). If such a switch is not present on the equipment, it is recommended that a door interlock switch (not included, min. 3A 24VAC rating) be installed and wired into the 24VAC ballast power circuit (see Wiring Diagram).
Mount the ballast using the included sheet metal screws or other appropriate fasteners, in a location close enough to connect the 24VAC ballast power wires to the 24VAC transformer (not included), and to connect the ballast lamp cable to the lamp. If the ballast is not in a location protected from UVC exposure, protect the ballast with the included shield, or by fabricating and installing a sheet metal shield or equivalent. DO NOT wrap the ballast in tape or cover the ballast with anything that would insulate or reduce the ability of the ballast to dissipate heat.
Route the ballast lamp cable to the lamp, providing sufﬁcient support to prevent entanglement with other components (such as a blower wheel or removable panel fasteners), and reduce stress on the Mounting Bracket Assembly.
Attach the ballast cable connector to the lamp base, ensuring correct alignment of the rectangular pin arrangement. The connector may be connected in either of two positions for which the pins line up. Ensure that the lamp connector is ﬁrmly attached and that the sealing boot is pushed fully onto the lamp base.
Connect the ballast 24 VAC wires to the 24 VAC transformer secondary (output) terminals (see Wiring Diagram), or the alternate installer-supplied door interlock switch if used. Secure the wires to prevent entanglement with other components (such as a blower wheel or removable panel fasteners).
Apply the Safety label to an area of the access panel or other area of the equipment or duct such that the warning information is clearly visible (see Figure 8), and through which the lamp may be seen. Clean the surface of dirt, oil, and other contaminants before applying the label.
Drill a 3/8” hole through the center of the Safety Label, where indicated by the dashed circle (see ﬁ gure 7).
Snap the clear plastic Safety Viewport into the hole (see Figure 8). The lamp may be safely viewed through the viewport while it is lit.
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™ AirPurifying System out of the plenum. Avoid touching the glass portion of the lamp with your hands.
Verify that all electrical connections are tight and that the lamp and bracket is secure.
Replace all access panels and other items that may have been removed during the installation, such as electrical box covers, etc.
Verify that the Safety Viewport is securely fastened in the hole drilled through the Safety Label.
WARNING: BEFORE RESTORING POWER TO THE HVAC SYSTEM OR THE TRANSFORMER POWER SOURCE, VERIFY THAT NO OPENINGS EXIST THROUGH WHICH UVC RAYS FROM THE LAMP MAY ESCAPE. VERIFY THAT ALL ACCESS PANELS AND DUCTWORK ETC. HAVE BEEN REPLACED AND SEALED IF NECESSARY, AND THAT THE SAFETY VIEW PORT IS SECURELY FASTENED IN PLACE.
Restore power to the HVAC system and the transformer power source. Look through the Safety Viewport to verify that the lamp is lit.

BRACKET MOUNT INSTALLATION THROUGH A-COIL DELTA PLATE OR PLENUM
If the lamp is to be mounted externally on the plenum or an air duct, or if the lamp is to be mounted through a delta plate (covers the end of A-coil in certain air handler designs), follow these steps for installation:

Separate the lamp mounting portion of the Lamp Bracket from the remainder of the lamp bracket (see Figure 4), by bending back and forth or cut with snips or hacksaw.
Attach the shield to the separated bracket, on the side opposite from the lamp mounting studs (see Figure 5), if it is to be used, using the supplied #8-32 self-threading screws.
Attach the lamp to the lamp bracket. Loosen the clamp bracket nut, inserting the lamp through the hole, swivel the clamp bracket fully back over the ﬂange of the lamp base, and retighten the clamp bracket nut. (See Figure 5)
WARNING: DO NOT use the supplied wingnut if the lamp bracket is installed externally on a duct or surface not internal to an air handler or duct system! For safety, a hand tool is required to remove the lamp if the installation is not internal as described.
Mark the location for the lamp, and cut a 2” round hole (1” hole if the shield is not used) in the mounting surface, using care to avoid damage to equipment or concealed wiring. If the lamp is to be mounted on duct board, fabricate a mounting surface by cutting a 6” x 6” square of suitable sheet metal. Cut the hole for the lamp in the sheet metal and the duct board, and tape the sheet metal securely to the duct board using mastic-backed metal tape.
Insert the lamp through the hole, orient the bracket such that the shield is in proper position, and secure the bracket to the mounting surface using three of the supplied sheet-metal screws, or other appropriate fasteners.
If mounting through the exterior of a plenum or air duct, use metal duct sealing tape (not included) to tape around the edges of the mounting bracket, to prevent UVC rays from escaping and prevent duct leakage.
Position the supplied cable clamp on the lamp cable such that the clamp hole is aligned with the fourth hole in the bracket, and loosely install the fourth screw or fastener through the clamp and bracket, into the mounting surface (see Figure 6). 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™ AirPurifying System out of the plenum. Avoid touching the glass portion of the lamp with your hands.
Attach the lamp cable to the lamp, pull up any slack in the lamp cable between the cable clamp and the lamp, and tighten the cable clamp mounting screw. (See Figure 6)
WARNING: ENSURE THAT THE CABLE CLAMP PREVENTS REMOVAL OF THE LAMP FROM THE BRACKET UNLESS THE LAMP CABLE IS DISCONNECTED FROM THE LAMP! This step is important to prevent the inadvertent removal of the lamp from the bracket before disconnecting the lamp cable from the lamp.
CAUTION: MAKE CERTAIN THAT POWER HAS BEEN DISCONNECTED TO THE HVAC SYSTEM, AND THE 24 VAC TRANSFORMER POWER SOURCE, BEFORE PROCEEDING WITH THE INSTALLATION!
Follow steps 9-19 in the Magnet Mount Installation section to complete the installation (see Figures 7, 8, 9).
WARNING: BEFORE RESTORING POWER TO THE HVAC SYSTEM OR THE TRANSFORMER POWER SOURCE, VERIFY THAT NO OPENINGS EXIST THROUGH WHICH UVC RAYS FROM THE LAMP MAY ESCAPE. VERIFY THAT ALL ACCESS PANELS AND DUCTWORK ETC. HAVE BEEN REPLACED AND SEALED IF NECESSARY, AND THAT THE SAFETY VIEW PORT IS SECURELY FASTENED IN PLACE.
