Surface Mount or Insert Mount Applications

The Bio-Fighter UV product line provides the installer with two options on how to apply the technology to an HVAC system, surface mount or insert mount. The method chosen should be based upon how the system is, or has the propensity to be, contaminated with microbiological organisms, customer / installer safety, and ease of maintenance.

When to use a Surface Mount

The Bio-Fighter Nomad and Nomad 2 products allow the installer to place the entire UV fixture into the air handler or ductwork by mounting the chassis onto an internal flat surface. The Nomad or Nomad 2 should be chosen when the installer does not want to drill any holes and does not want any of the UV fixture exposed externally. It is strongly recommended that installations of this type have a safety cut-off switch installed at the access panel.

When to use Insert Mount

The Bio-Fighter Triad products provide the installer with the capability of mounting the Triad chassis on an external surface and inserting the lamp into the air stream. This type of installation requires drilling hole(s) and is recommended where the installer does not want to remove an access panel on the HVAC system in order to maintain the UV fixture.

Air stream applications require maximum UV-C output, 2 lamp units are recommended for A-coil and return plenum applications.

VersaLight models are also available for applications with limited space. The remote mounted chassis allows the ballast to be mounted up to 6 feet from the lamp holders. The VersaLight is available in 1 or 2 lamp configurations with 14, 16 or 20" lamps.

Warning: The end(s) of the UV lamp(s) should never be installed closer than 2" to the opposite wall of the air handling unit. Installer must check lamp clearance.

Professional Installation Recommended: Although the Bio-Fighter is simple to install, it is recommended a professional contractor install your new Bio-Fighter. New electrical service may be required at the installation location and this should be performed by a professional. These UV light systems should take an hour or less to install.

Installation Notice: Do Not Mount Device In Any Location That Allows Ultraviolet Light To Be Seen After Installation. To prevent the viewing of UV light through the grille, the Bio-Fighter Germicidal UV System should NOT be installed in the return air stream of a closet return application.
