Types of Hazards
Warning
•Indicates a hazardous situation which, if not avoided, could result in
death or serious injury
Ultraviolet Radiation
•Avoid exposure to the lights when they are on unless protected by a
solid object or car window glass (a few types of scientific specialty
glass are transparent to UVC light)
•Lamps emit high power UV radiation that can cause cancer and/or
severe injury to skin and eyes in less than a minute
•Use only in an enclosed vehicle that is locked from entry during the
treatment time
•Lamps are in Risk Group 3 per ANSI/IESNARP-27.3-96
•If you can see the light without a protective barrier, you are being
exposed; the closer the more dangerous
Dangerous voltage
•The lamps operate between 50-120V AC
•Disconnect battery and turn the tool OFF before servicing
•Do not disassemble the control box for service
•Do not operate the tool when wet
Lamp breakage notice
•Lamp contains mercury. Manage in Accord with Disposal Laws. See
www.lamprecycle.org or 1-800-555-0050
•A lamp breaking is unlikely to have any impact on your health
•If a lamp does break indoors, ventilate the room for 30 minutes
•Do not use a vacuum cleaner
•Remove the broken parts with latex or nitrile gloves
•Put them in a sealed plastic bag and take it to your local waste
facilities for recycling

UV Overexposure
Symptoms can be delayed several hours to a day and include sunburn and photokeratitis (also known as
snow blindness or welder’s flash).
•Skin irritation can vary in severity depending on the level of exposure, a person’s genetics, and
some medications. Chronic exposure to UV radiation has been linked to premature skin aging
and skin cancer.
•UV radiation can damage the cornea, which is the outer protective coating of the eye.
Photokeratitis is a painful inflammation with symptoms such as an itching feeling like sand is in
your eye that can last for several days. Chronic exposures to short term UV radiation can lead to
the formation of cataracts.

Use and Operation
The Model 950 is designed for air and surface disinfection of an unoccupied vehicle with closed windows
and locked doors. Inactivation of a wide variety of microorganisms is accomplished with two germicidal
lamps that emit a wavelength of light at 254 nm. The treatment time required to inactivate varies by
type of organism, humidity, and temperature. The general relationship is more energy equals more of
the microorganism population is inactivated. Energy is the light intensity multiplied by the illumination
time. The model 950 is set to a time of 12 minutes to provide the energy dose recommended by the
International Ultraviolet Association (iuva.org) of 40 mJ/cm2.
Limitations of germicidal light are shaded areas that are unlikely to be treated well enough and should
be cleaned with another method such as wiping with an EPA List N which covers disinfectants for use
against SARS-CoV-2 (COVID-19).
A good complementary approach to protect both the people cleaning the vehicle and the users would
start with UVC disinfection first to reduce the bioactivity within the vehicle followed by hand cleaning of
shaded and high touch areas such as the steering wheel and door handles.
Use Example
A use example in a typical 4 door sedan (details depend on the vehicle’s specifics)
1. Use the model 950 as directed across the front seat area
2. Use the model 950 as directed across the back-seat area (or at the same time if 2 tools are
available)
3. Remove the tool(s)
4. Hand clean the high touch areas and areas that are shaded from the light such as
oSteering wheel and controls (turn signals, lights)
oDoor handles
oGear selector
oHandles outside of the car
Operational Steps
1. Check the tool for damaged, dirty, or broken lamps –do not use a broken tool.
2. Attach battery
3. Remove trash and debris from the vehicle’s interior
4. Close all of the vehicle’s windows
5. Vehicle side 1
a. Place the tool on the seat closest to you
b. Pull out the strap and hang it over the center of the door frame as you close the door
while holding the strap
c. Pull the strap with enough tension to lift the end of the tool slightly up towards your
hands
d. Slide the cam lock (located near the warning label) up to the door frame and close the
cam lock
6. Vehicle side 2
a. Turn the tool on

8
b. Press the start button –There is a 1-minute delay before the tool turns the lamps on
c. Pull out the strap and hang it over the center of the door frame and close the door while
holding the strap
d. Pull the strap with enough tension to lift the end of the tool so it is roughly centered
between the seat and the roof
e. Slide the cam lock (located near the warning label) up to the door frame and close the
cam lock
7. Return to side 1 and adjust to center the tool if necessary.
8. Lock the doors.
9. Wait for the lamps to shut off and either the green ‘process complete’ light or the red flashing
error light to illuminate before entry
10. Turn off the tool
11. Fold up the orange straps and place them in the elastic band near the clip
12. Remove the tool from the vehicle
Helpful Information
•The tool does not have to be level –the purpose it to equally treat the vehicle’s interior by
roughly centering it in the cabin.
•Fanfolding the strap is usually the easiest method to put it back into the elastic band. Start by
holding the strap with the elastic band in your hand.
•Placing and removing the tool with the straps unclipped may be better for your work efficiency
and provide less chance of contaminating the tool.
•Keep the lamps clean by storing the tool in the provided box or covered in a clean area.
•The green light and fan will turn off after 30 minutes to conserve battery power.
•The fan will stay on until the control box temperature is below 81⁰F. It’s ok to turn the power
switch off before the fan turns off by itself, the tool will cool naturally.
•To run the process the vehicle must be above 36⁰F and below 113⁰F.
•Lamps emit a lower intensity of UVC at colder temperatures, so a sensor automatically detects
the temperature and adjusts the treatment time as needed. The maximum time is 24 minutes at
36⁰F.

Battery and Charging
A Milwaukee® M18™series rechargeable battery with a capacity of 5 A-hr is provided with the tool. It
should be recharged with the provided charger or another compatible charger as needed. The battery
has a built-in level indicator and should be at least at 1 bar out of 4 before starting a treatment process.
The tool will automatically detect an error if the battery
level is too low to start a process run. Charging a fully
discharged battery will take about 1.5 hours.
Using M18™ compatible replacement batteries is
acceptable. Lower or higher capacity batteries are also
acceptable but will change the number of treatments
before a recharge is needed. Extra-large capacity batteries
will fit and operate the tool, but the extra weight may
make it difficult to lift with the straps.
The battery needs to be slid into place until it clicks into
the locked position. Press both red tabs to release before
sliding the battery off the mount.
Maintenance
Caution: Remove the battery before all maintenance and service.
Lamp cleaning - small particulates
Use a canned air duster or compressed air nozzle with the lamp covers in place.
Lamp cleaning –heavy particulates or visible debris
1. Remove a lamp cover by removing the 4 thumbscrews and by carefully sliding the cover off the
end of the lamp
2. Wear latex or nitrile gloves to keep the lamps clean
3. Moisten a clean, lint-free cloth with isopropyl, ethyl, or denatured alcohol and wipe down the
surface of the lamp(s)
4. Replace the lamp cover by sliding in over the lamp making sure the end of the lamp is captured
by its holder in the end cap
5. Replace the 4 thumbscrews, finger tight
Lamp lifetime
Lamps are rated for 8,000 hours of continuous use, but the manufacture’s lifetime needs to be derated
due to the high number of on/off cycles relative to run time. We recommend that the lamps be replaced
after 6,000 hours of run time. As an example, one 8-hour shift of operation for a year is about 2,000
hours.

Effect of UV on Vehicle Materials
Due to the absorption of energy, plastic and fabric materials will breakdown with prolonged exposure
which shows up as yellowing, surface cracks, and ultimately mechanical failure. Most plastics that are
designed for outdoor use, have UV coatings or inhibitors added to the material to prolong the life of
materials. This was a much bigger problem in the past for car manufacturers, so UV inhibitors are now
widely added to materials that are expected to receive sun exposure.
