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 PDC4000 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.
