purpose as described in this Owner’s Manual.
PLEASE READ AND SAVE
THESE IMPORTANT SAFETY
INSTRUCTIONS
IMPORTANT SAFEGUARDS
When using electrical equipment, basic safety
precautions should always be followed to reduce the
risk of fire, electric shock, and injury to persons,
including the following:
• Read all instructions before using this Hydroxyl
Generator.
• To avoid fire or shock hazard, plug the equipment
directly into a grounded AC electrical outlet.
• If the generator is covered by a bag when shipped:
Remove plastic bag before use.
• Keep the cord out of heavy traffic areas. To avoid
fire hazard, NEVER put the cord under rugs, near
heat registers, radiators, stoves, or heaters.
• To protect against electrical hazards, DO NOT
immerse in water or other liquids. Do not use near
water.
• Do not leave the generator in use unattended
around those requiring close supervision.
• WARNING! Always unplug the generator before
moving it, cleaning, or whenever the generator is not
in use. Be sure to pull by the plug and not the cord.
• NEVER drop or insert any object into any openings.
• DO NOT operate any generator with a damaged
cord or plug, if motor fan fails to rotate, after the
generator malfunctions, or if it has been dropped or
damaged in any manner. Return generator to
manufacturer or authorized repair facility for
examination, electrical or mechanical adjustment, or
repair.
• Use generator only for intended use as described in
this manual. Any other use not recommended by the
manufacturer may cause fire, electric shock, or injury
to persons. The use of attachments not
recommended may cause hazards.
• INDOOR USE ONLY!
• NEVER block the air openings, grills/outlets or place
on a soft surface such as a bed or sofa, as this could
cause the unit to tip over, blocking the Air Intake
Opening/Grill.
• Keep unit away from heated surfaces and open
flames.
• CAUTION: For General Ventilating Use Only. Do
Not Use to Exhaust Hazardous or Explosive Materials
and Vapors.
• DO NOT attempt to repair or adjust any electrical or
mechanical functions on this unit. Doing so will void
your warranty. The inside of the unit contains no user
serviceable parts. All servicing should be performed
by qualified personnel only.
• WARNING! To reduce the risk of fire or electric
shock, DO NOT use this generator with any solid-
state speed control device.
• DO NOT place anything on top of generator.
• DO NOT plug the cord in with wet hands: electric
shock could result.
• NEVER use detergents, gasoline, glass cleaner,
furniture polish, paint thinner or other household
solvents to clean any part of the generator.
• DO NOT under any circumstances cut or remove the
third (Ground) prong from power cord. For personal
safety, this generator must be properly grounded.
•The MDU/Rx™unit performance is not affected
by external sources of electromagnetic radiation
from devices such as cellphones radio etc. that
generate wavelengths greater than those
produced by the device, as these wavelengths
of light do not penetrate the quartz housing of
the optics. X-rays may cause the quartz to
become cloudy and it is advised that the
MDU/Rx™ device not be used in areas that
generate x-ray radiation or be placed behind
shields used by technicians in these areas.

SAFETY INFORMATION
SAFE HANDLING AND DISPOSAL OF MERCURY
Mercury is used in the MDU/Rx™ device in order to generate the plasma needed to produce UV-C radiation. This is
similar to the use of mercury in many types of commercial, fluorescent light fixtures. As long as the glass or quartz
outer bulb is intact, mercury is contained within the fixture and poses no health hazard. In the event that an optic
breaks, less than 25 mg of mercury could be released. This is much less than what is present in a commercial
thermometer. Liquid metallic mercury is hazardous due to its potential to release mercury vapor. In humans,
approximately 80% of inhaled mercury vapor is absorbed via the respiratory tract, where it enters the circulatory
system and is distributed throughout the body. Short term exposure to 25 mg of spilled mercury does not pose a
health hazard, provided that the source of the mercury is removed promptly. Chronic exposure by inhalation, even at
low concentrations in the range 0.7–42 μg/m3, can cause effects such as tremors, impaired cognitive skills, and sleep
disturbance in workers. The OHSA limit for occupational exposure of elemental mercury is 0.1 mg/m3. Mercury is
also used in most fluorescent light fixtures.
In the event that the device optic light does not function, the optics should be checked to ensure that they are intact.
If the optic is cracked, but not broken, it should be replaced. Cracked optics should be double sealed in plastic bags
and disposed of according to local, approved procedures. In the event that the optic breaks and the mercury is
spilled clean-up should be done immediately according to the following procedure published by the Environment
Protection Agency.
Evacuate the room for at least 15 minutes
Do not attempt to clean up the spill with a
vacuum cleaner, mop or broom
Dispose of clothing, fabric etc. that has come
in contact with mercury; do not wash
Only the individual to clean up the spill
should re-occupy the space
Close the doors to the area of the spill and
turn off the HVAC system; open exterior
windows and direct room air out of the
window with fans or use an exhaust fan if the
area is equipped with one that vents directly
outdoors
Cover shoes with disposable foot covers or
wear shoes that will be disposed of
Remove jewelry as mercury will amalgamate
with metals and ruin them
Use a commercial mercury spill clean-up kit
to remove the spilled mercury. ( See list of
suppliers below)
Identify items in the spill area that can be
cleaned and those that cannot. Non-
porous surfaces (finished wood, plastic or
concrete) can be cleaned following this
guidance. Porous surfaces or fabric-covered
items (upholstery, carpeting, stuffed animals,
pillows, backpacks, unfinished wood, cork,
cardboard) are difficult to clean because
mercury beads may be trapped in these
materials. If you decide you cannot clean
these items, place them in plastic trash bags
or cover or wrap them in a double layer of
plastic and carefully seal with tape. Place the
wrapped items in a secure place, preferably
outdoors and out of the reach of children and
pets. You should consult with a trained
professional about how to decontaminate or
dispose of these items safely.
Wear gloves to carefully pick up the
larger pieces of broken glass and what
remains of the broken device and place
them on a paper towel. Gently fold the
paper towel around these pieces so you can
pick the bundle up and place it in a zipper-
type plastic bag. Use index cards or stiff
cardboard to push smaller pieces of glass
and mercury beads together into a pile.
Shine a flashlight at an angle to locate
beads of mercury. The beads will reflect light
from the flashlight. Check for mercury in
cracks or in hard-to-reach areas where
beads may be hidden or trapped. Check a
wide area beyond the spill.

SAFETY INFORMATION
Use the eyedropper to collect mercury
beads and place them in the plastic bag.
Hold the eyedropper at an angle to draw the
mercury into the tip. Keep the eyedropper at
an angle to stop the mercury from rolling
back out until you can put the mercury into
the plastic bag. Wrap tape (sticky side out)
around your gloved fingers and carefully
use it to pick up any remaining glass or
beads. Check again with the flashlight to be
sure that no beads of mercury remain.
At this point, mercury beads may still be
trapped in cracks or crevices on irregular
surfaces. Sprinkle sulfur powder over the
contaminated area and rub it gently all over
the surface and into the cracks with a paper
towel. Sulfur powder binds with mercury.
Use a paper towel dampened with water
followed by wiping with another damp paper
towel to clean up the sulfur and mercury.
Place the used paper towels in a zipper-type
plastic bag.
Put all the items that were used to pick up
the mercury, including index cards or
cardboard, eyedropper, contaminated
tape, paper towels, and zipper-type bags
into the trash bag. Carefully remove rubber
gloves by grabbing them at the wrist and
pulling them inside out as they come off.
Place the used gloves in the trash bag.
Carefully seal the trash bag that contains
the mercury contaminated waste and put it
in a secure place, preferable outdoors and
out of reach of children and pets until it can
be disposed of safely.
If possible, open a window and use a fan
to ventilate the area to the outdoors for
24-48 hours before resuming normal use. If
possible, heat the area (for example, with a
space heater) while still ventilating to the
outdoors. Avoid blowing the exhaust back
indoors or into other nearby residences.
Clothes or shoes that did not come in
direct contact with liquid mercury should
be removed and put into the trash bag
that was left outside the contaminated area
at the beginning of the cleanup. Close the
trash bag and take it outdoors. Carefully
remove the shoes and or clothing from the
trash bag and air them out thoroughly
outdoors for 24 to 48 hours. After the
outdoor airing, items that are washable can
then be laundered.
Dispose of contaminated items properly!
Mercury-contaminated items should not be
placed in the regular household trash.
Contact your town or county officials for
information about hazardous waste disposal
in your community.
