INSTALLATION
STEP 1. CHOOSE A LOCATION FOR THE CX-PRO
To prevent water damage or electric shock, do NOT mount unit under a humidifier.
A. CX-Pro may be installed in supply duct, return plenum or above AC coil.
B. CX-Pro may be installed in upflow, downflow, or horizontal flow ducts and plenums.
C. CX-Pro may be installed directly onto a sheet metal air duct, or onto a fiberglass ductboard
when installed using the included ductboard adapter plate.
D. If locating a CX-Pro above an AC coil: position so that the maximum surface area of the AC
coil is illuminated, installing as close to the AC coil as possible without damage to the AC coil.
E. DO NOT locate within 30 inches (direct exposure) of plastic materials or air filters.
Use care to avoid damage to the AC coil, wiring or other components while
installing the CX-Pro.

Unplug the unit before installing the lamp.
A. 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 to the 230 volt position (Figure 1). The plug must be replaced
and wiring must be done to applicable electrical codes.
