INSTALLATION
• Best results are achieved when the unit is installed where the HVAC
air temperature is most constant. Therefore, the preferred installation
return side of the furnace. If return side installation is not possible, install
the unit on the supply side, keeping it as far from the heat/cooling source as
possible, and in the main airstream.
• Do not locate the unit within 20” of any plastic material that will be
exposed to the UV light, such as a return side humidifier or certain
filters. Check with the filter manufacturer to see if their material is U
V resistant.
Over time, UV light will degrade many plastic materials.
• Do not touch the glass portion of the lamp with bare hands because oils fro m
the hands can cause “hot spots” which reduce lamp life. Handle either by th e
porcelain caps or use a soft cloth. If you accidentally touch a lamp, wipe it o ff,
using a soft cloth dampened with rubbing alcohol.
