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.
