BIO-FIGHTER®XL INSTALLATION & OPERATION MANUAL
WARNING
UV Light Hazard.
Can cause serious eye and skin
damage.
Do not look at UV-C light. Wear UV-C
eye and skin protection.
SPECIAL INSTALLATION NOTESUNPACKING
PLACEMENT
Do not install in closet return grille
applications.
Do not expose wiring or plastic parts to
UV-C light.
Do not install where UV-C light can be seen
after installation.
Do not install beneath a humidifier.
If the UV device is installed on the inlet side
(return air side) of a coil, make sure that
the HVAC system is configured such that
the blower is located between the return
air filter and the inlet side (return air side)
of the coil, such as would be found in a
traditional upflow, or horizontal furnace with
the coil placed after the heat exchanger.
If the UV device is installed near an air filter,
check with filter manufacturer for UV-C
resistance properties.
If the desired UV installation location
is intended to irradiate an air filter, to
neutralize the microbiological matter on
the air filter surface, such as would be
found in the return air drop of a basement
application or in the return plenum of
a horizontal system in an attic; take
precautions as described in note above,
and make sure the UV fixture is placed
on the return side of the filter. DO NOT
INSTALL THE UV FIXTURE ON EITHER
SIDE OF THE FILTER IN HALL / CLOSET
RETURN AIR APPLICATIONS. (See
ATTENTION! Warning sheet #212945-00).
The Bio-Fighter® XL is packaged with a
clear protective film covering the polished
aluminum reflector. This film must be
removed prior to operation. First remove
the lamp from the lampholders and lay
to the side. Then peel the film from the
reflector.
Each foot of fixture length will irradiate a
three square foot area. For example, one
five foot Bio-Fighter®XL can irradiate 15
square feet of surface area. To maximize
efficiency of the UVC light, each fixture
should be placed 18-22 inches from the
surface to be irradiated. Ensure no plastic
parts or wire insulation is exposed, and that
wherever the unit is placed, no light can be
seen after installation.
WARNING
Electric Shock Hazard.
Can cause injury or death.
Electrical wiring of the unit to the
HVAC system should be done by a
licensed HVAC technician or
electrical installer.

BIO-FIGHTER®XL INSTALLATION & OPERATION MANUAL
COIL SIZING REFERENCE
INSTALLATION
Determine the dimensions of the coils or
area to be irradiated.
Use the Coil Sizing Reference to determine
the number of lamps needed for proper
coverage.
Larger coils may require multiple Bio-
Fighter kits.
UV LAMP CONFIGURATION GUIDELINES
The distance between UV lamp(s) and the
irradiated surface should be between 6”-
18” is optimal.
The distance between stacked UV lamps
should not exceed 35”.
The distance between end to end UV lamps
should not exceed 12”.
The distance of UV lamp ends to the edge
of irradiated surface should not exceed 6”.
One single lamp can cover 36” of coil
height, 18” above and 18” below. Each
lamp also covers an additional 6” of width
beyond the ends of the lamp, 3” on either
side of the lamp.
LAMP SPACING
Overlap lamps where necessary
12" maximum space between lamps
6" maximum space to end of coils

acceptable and is recommended for
airborne disinfection.
