Field Controls Healthy Home System Duo-2000, Installation & Maintenance Instructions

1. ALWAYS be sure the unit is unplugged during installation or
service procedures.
2. DO NOT leave fingerprints on UVC germicidal lamp. Clean
lamp with a dry cotton cloth and isopropyl alcohol.
Note: Due to directional airflow installation options, the Healthy Home System 3x3 Product Brand Label
is enclosed for proper upright placement at the field installation. The Duo-2000 installation is specific
to direction of airflow and must be properly positioned when choosing upflow, downflow, or horizontal
airflow application. Pay attention to directional airflow arrow for proper installation. The installation of
the Duo-2000 may be on the return air side, supply air side, or above the AC-Coil in the supply plenum
of the HVAC system. For best results, the HVAC air filter should be upgraded to a Field Controls High
Efficiency FC8 or FC11 pleated media air cleaner. Do not locate the Duo-2000 within 24 inches (direct
exposure) of plastic materials or air filters. UVC radiation will degrade many plastic materials over time
with direct exposure. The Duo-2000 is designed to be installed on indoor HVAC forced air ducted
systems. Do Not install outdoors. Product is not designed to be exposed to outdoor elements.

. The ballast is factory set to 120 VAC. The voltage can be changed in the field to 230 VAC by
sliding the voltage selector switch in (photo - A) to the 230 volt position. The plug must be replaced and
wiring must be done to applicable electrical codes.
2. Remove the front electrical cover from the Duo-2000 and remove the (4) wing nuts in (photo - B)
that attach the unit to the Air Purifier's duct mounting plate.
3. Slide off the mounting plate and use it as a template by outlining inside cutout and (8) mounting
holes with a pencil. Make sure the wide portion of the mounting ring hole is facing the air stream. Cut
out the mounting hole from the duct and drill the (8) mounting holes with a 9/64 drill bit. (photo - C)
4. Fasten the mounting plate to the duct by installing and tightening all (8) #12 sheet metal screws
supplied and slide in the body of the Duo-2000. Reattach the (4) wing nuts hand tight and replace
the front cover.
5. Attach the quick connect power cord and plug in to any standard 120 volt electrical outlet. Verify
lamp operation by looking through the view port on front cover. (photo - D). Continuous UVC germicidal
lamp operation is recommended. At .09 cents per kilowatt hour, continuous lamp operation cost 10.5
cents per day. Cycling the UVC germicidal lamp on and off degrades lamp performance much faster and
shortens the filament life.
