may need to be created prior to installation. Ensure
adequately clear space exists behind any drilling location
to prevent potentially damaging other equipment when
puncturing sheet metal.
4. Mark appropriate lamp installation position relative to
the evaporator coil. Please reference image 90-2737 for
UVC lamp placement in relation to the coil. The location
should also be centered on the ductwork for even light
distribution. Ensure there will be enough free space for the
bracket and magnet once installed.
5. Locate appropriate ballast installation position relative to
the marked lamp installation position. Ensure this position
will be within reach of the ballasts power cord once both
are installed. Conrm access to 24V AC power is available
to be connected after ballast installation (if unavailable,
a separately sold AC transformer is recommended). Mark
screw hole mounting points for future reference.
6. Mark appropriate UV shielded view port position relative to
lamp location. The view port should be placed 3-12 inches
away from light source with direct line of sight to allow for
monitoring of lamp status when unit is powered on. Only
visible spectrum blue light will pass through this view port,
while the damaging UV light is completely blocked.
7. Mount ballast at previously marked position. Align the
ballast into desired nal position before securing with
sheet metal screws at mounting points. Ensure adequately
clear space exists behind drilling location to prevent
potentially damaging other equipment when puncturing
sheet metal.
8. Apply included informative and warning stickers in a
clearly visible location near the lamp and ballast.
9. Cut sheet metal to allow power cord access to the
product once installed. This can be achieved by drilling
a 1” hole near the nal lamp position or by notching the
access panel. If drilling a hole, use the stepped drill bit
at the previously marked location. If notching access
panel, cut sheet metal with shears, and dry t the power
cord into the notch. Ensure no sharp edges will contact
the power cords insulation. Ensure adequately clear
space exists behind drilling location to prevent potentially
damaging other equipment when puncturing sheet metal.
10.Add offset bracket to main bracket, secure pieces with the
two included self-tapping Philips screws.
11. Attached the magnet to the offset bracket using the
included long Philips screw and nut. The Philips head
should be on the exterior of the assembly, opposite the
base plate.
12.Mount UVC Lamp in housing assembly. Start by lightly
threading 2 included Philips screws into the lamp retainer
mounting points, allow enough space for retainer ring
plate to slide under screw head. Carefully cut open lamp
packaging and put on protective gloves. Insert lamp
through center lamp hole until contact is made with the
shaft shoulder near the lamps power terminals. Align
retainer ring mounting slot with previously installed screws
and compress the lamps shaft shoulder between the
retainer ring and mounting plate. Twist the retainer ring
so that the screw shafts contact the opposite end of the
mounting slots. Tighten down screws by hand.
a. ONLY handle lamp with clean gloves. If lamps surface
becomes contaminated, clean with isopropyl alcohol.
13.Carefully position the assembly inside the duct work, allow magnet to fully adhere to sheet metal before releasing grip.
Depending on space requirements, you may need to follow step 15 rst to allow unit to be plugged in.
