APCO RT Installation
APCO RT is usually installed on the supply
side duct just above the air system (upstream
of a humidifier). It can also be installed on
the return side if necessary.
Orient so the air flows past the UV light first
before the carbon. Position the unit so the
UV light does not shine directly on non-uv-
resistant materials (filters, humidifiers, flex
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.
