WARNING
POSSIBLE EXPOSURE TO ULTRAVIOLET RADIATION AND
HAZARDOUS VOLTAGE!
Failure to disconnect power before servicing could result in severe
electrocution or burns leading to serious injury or death. This product
contains components that emit Ultraviolet Light radiation (UV-C) which
can be harmful to the skin and unprotected eyes. Disconnect all electrical
power, including remote disconnects, and ensure UV lights are off before
servicing. Follow proper LOCKOUT/TAGOUT procedures to ensure the
power cannot be energized while in service.
Installing UV Lamps
Units equipped with an IAQ section will be shipped with all
sheet metal and wiring in place. The UV lamps will need to be
installed in the eld. The lamps are packaged inside the unit for
protection during transit.
• Wear cotton or polyester gloves and safety glasses while
handling the lamps.
The UV light rack utilizes two dierent lamp lengths to span
the entire width inside of the cabinet. There will be one 33” and
one 61” long lamp used per row of lights. This unit will have 6
rows total (8 rows for C-cabinet units). The 33” and 61” lamps
are slightly oset in each row as seen in Figure 119.

The IAQ sheet metal rack is held into place with 4 screws
to secure it to the air handler. To ease the installation of UV
lamps, unscrew these 4 fasteners at the corners of the rack
as detailed in Figure 120. After the fasteners are removed,
disconnect the power at the base of the right side of the rack
as seen in Figure 121.

Once the power has been disconnected, slide the rack out of
the unit 1/3 of the way so you can access the lamp clips that
are the furthest apart while standing outside the unit as seen in
Figure 122.
