Install Instructions

APCO RT Installation
APCO RT is usually installed on the supply
side duct just above the air system (upstream
of a humidier). It can also be installed on
the return side if necessary.
Orient so the air ows past the UV light rst
before the carbon. Position the unit so the
UV light does not shine directly on non-uv-
resistant materials (lters, humidiers, ex
duct, etc.). Ideally the UV light shines on the
coil.
For dual systems select a remote UV light
location that shines on the greatest surface
area or the area with the most microbial
growth. Refer to the Optional Remote UV
Light section for installation instructions.
