INDICATION FOR USE

This product is not sold as a medical device and is not for the purpose of diagnosis of any disease or condition nor for use in the mitigation, treatment, or prevention of any disease or condition.

GENERAL INFORMATION

There are different size units available, depending on the tonnage of your HVAC system. See chart below for determining the needs of your home.

The FlexMount™ UV-Aire™ system is provided with a unique patent-pending, magnetically-attached Mounting Bracket Assembly. The mounting bracket assembly may be rotated and/or extended relative to the mounting surface, to provide maximum flexibility in mounting positions and configurations.

A reflective aluminum shield is included which may optionally be used to shield wiring, ductwork and parts which could be damaged by UVC exposure, and/or concentrate the UVC rays in a particular area such as the A-coil. The shield may be attached to the lamp bracket in four different positions, so that the bracket assembly may be positioned in such a way as to create minimal obstruction to air flow, and provide maximum flexibility in positioning of the lamp relative to the bracket and mounting surface.

The part of the lamp bracket to which the lamp is attached may be separated from the mounting bracket assembly, and used for mounting the lamp through a delta plate covering the end of the A-coil, or for mounting the lamp inside of a plenum or air duct.

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.

WARNING: Before installing or servicing a humidifier, air filter, heat system, or this unit, etc., always turn all power OFF and have unit unplugged. Electrical shock can cause personal injury or death. Never expose eyes or skin to direct UVC light from any source.
WARNING: To prevent water damage or electric shock, do not mount unit under a humidifier.
WARNING: Designed for a closed duct system. Do not mount near a supply or a return air opening.
WARNING: This product is designed for installation in the interior of weather-protected HVAC equipment or ductwork, or on the exterior of protected ductwork only. For use on gas fired, oil fired, electric, split system heat pump forced air systems*, and the interior of weather-protected heat pump packaged units**.

*Split system heat pumps are systems where the air handler and the air conditioning compressor are separate units.
**Packaged units are systems where the air handler and the air conditioning compressor are built together and are installed outside of the building

MAGNET 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.

Figure 1 Typical Installation

3. Attach the Shield to the Mounting Bracket Assembly, if it is to be used, by bending the tabs on the shield over the Lamp Bracket notches (see Figure 2). This will hold the shield in place during installation and lamp replacement. The shield will be held firmly in place when the lamp is installed.

Attach the Shield in the best of four possible positions, to shield sensitive wiring and ductwork etc., and/or concentrate the UVC irradiation on a certain area or surface, and allow positioning of the mounting bracket that creates minimal obstruction to air flow.

Figure 2

4. Attach the Lamp to the Mounting Bracket Assembly with the supplied #8-32 wing nuts (see Dimensional Drawing). 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.

5. Separate the Lamp Cable from the Ballast output cable connector, if attached. The cables have mating watertight connectors to allow ease of installation and service (see Figure 3).
6. Attach the Lamp Cable lamp 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.

**** 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.

7. 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 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.
8. 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!

9. Mount the 50VA, 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 120V transformer 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).

10. Mount the Ballast using the included sheet metal screws or other appropriate fasteners, in a location close enough to connect the 24VAC ballast power cable to the 24VAC transformer (not included), and to connect the ballast output cable to the lamp cable connector. 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.
11. Route the Ballast output cable (watertight connector on the end) to mate with the Lamp Cable, and provide 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.
12. Connect the Lamp Cable connector to the matching connector on the Ballast output cable and ensure that the connectors are fully mated. These connectors are designed to prevent misalignment of the mating connectors; line up the projecting tabs of both connectors to allow connection (see Figure 3).
13. Connect the Ballast 24 VAC power cable to the 24 VAC transformer secondary (output) terminals (see Wiring Diagram), or the alternate installer- supplied door interlock switch if used. Secure the cable to prevent entanglement with other components (such as a blower wheel or removable panel 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.

14. Identify an area of the access panel or other area of the equipment or duct through which the lamp may be seen. Verify that the surface is free of dirt, oil, and other contaminants, peel of the label backing and apply the Safety label to the surface such that the warning information is clearly visible (see Figure 8).
15. Drill a 3/8” hole through the center of the Safety Label, where indicated by the dashed circle (see figure 7).
16. 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.
17. Verify that all electrical connections are tight and that the lamp and bracket is secure.
18. Replace all access panels and other items that may have been removed during the installation, such as electrical box covers, etc.
19. 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.
20. 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:

Figure 4

1. 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.
2. 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. Any of the four attachment positions may be used.

Figure 5

3. Insert the lamp through the oval hole in the bracket and shield base, and attach to the mounting studs using the supplied #8-32 locking nuts (see Figure 5). Do not use the supplied #8-32 wingnuts, unless the lamp is to be installed inside an air handler or other equipment or structure requiring the use of a tool to access.
4. Mark the location for the lamp, and drill or cut a 2” round hole (may be an oval hole 2” x 1” 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.
5. Insert the lamp through the hole, orient the lamp such that it presents the least obstruction to airflow or 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.

6. 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.

Figure 6

7. Position the cable clamp installed on the Lamp Cable such that the clamp hole is aligned with the fourth hole in the bracket, and install the fourth screw or fastener through the clamp and bracket, into the mounting surface (see Figure 6).
Note: This step is important to preclude the inadvertent removal of the lamp from the bracket before disconnecting the lamp cable from the lamp.

**** 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.

**** CAUTION: MAKE CERTAIN THAT POWER HAS BEEN DISCONNECTED TO THE HVAC SYSTEM, AND THE 24 VAC TRANSFORMER POWER SOURCE, BEFORE PROCEEDING WITH THE INSTALLATION!

8. Follow steps 9-20 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.
