shown in (photo - B).
4. Remove the Duo-2000 body by sliding out of the duct

5. Use a cotton cloth with isopropyl alcohol and gently clean
the surface of the lamp.
Note: If the honeycomb photo-catalyst on the left and right side
of the UVC germicidal lamp appears to be a light gray color and
the individual cells are open and clear, there is no need to clean
the catalyst as it is self cleaning. If for any reason the catalytic
cells require cleaning, sit the unit on end, on a flat surface, with
the electrical enclosure facing up. Spray the catalytic cells with
Windex and flush the catalyst with warm water until clean.
CAUTION: Allow the unit to thoroughly dry before
replacing into service.
6. Replace the Duo-2000 back into the duct mounting plate
and tighten the (4) wing nuts hand tight. Replace the front
electrical cover and plug the quick connect power cord back
into the unit.
