“READ AND SAVE THESE INSTRUCTIONS”
RISK OF ELECTRIC SHOCK CAN CAUSE
INJURY OR DEATH.
UNPLUG UNIT BEFORE SERVICING.
TO REDUCE THE RISK OF ELECTRIC SHOCK:

All Nikro Industries Inc. products that have rated efficiencies of 99.97% @ 0.3
microns and/or 99.99% @ 0.3 microns, have H.E.P.A. filters that have been
individually tested to meet these minimum efficiencies.
Although all the filters have been pre-tested, the possibility of leaks or filter failure due to
handling, transportation, punctures, loaded filters, moisture, wear and tear, etc., does
exist.
Therefore, when using this equipment in highly sensitive areas or where any
release of particles above and beyond the minimum efficiencies would be
detrimental and harmful to humans, plants or property; it is strongly recommended
that the units be individually tested prior to their use.
This is to assure that they are maintaining the efficiency levels, which they were
designed to filter out.
FAILURE TO DO SO COULD RESULT IN SERIOUS HARM TO HUMAN LIFE,
PLANT LIFE AND/OR PROPERTY.
BACKDRAFTING AND CARBON MONOXIDE FUMES
To prevent the backdrafting of deadly carbon monoxide, when using your
PDU4000 to create a negative pressure in a containment area, turn off all open
combustion devices such as but not limited to fireplaces, hot water heaters,
furnaces, boilers etc.
