10 GALLON
HEPA FILTERED VACUUM
MODEL #PD10088 & PW10088
INSTRUCTION MANUAL

2
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.

OPERATING INSTRUCTIONS
INSPECTION
Thoroughly inspect your machine for any shipping damage. Your machine has already been thoroughly tested at
the Nikro Industries manufacturing plant prior to shipping.
ELECTRICAL SPECIFICATION
This machine is designed to operate on a 15 amp. 115V., 60 hz., AC circuit. A deviance of this could cause serious
damage to the unit.
GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should malfunction or breakdown, grounding provides a path of least
resistance for electric current to reduce the risk of electric shock. This appliance is equipped with a cord having an
equipment-grounding conductor and grounding plug. The plug must be inserted into an appropriate outlet that is
properly installed and grounded in accordance with all local codes and ordinances.
WARNING – Improper connection of the equipment-grounding conductor can result in a risk of electric shock.
Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded.
Do not modify the plug provided with the appliance – if it will not fit the outlet, have a
proper outlet installed by a qualified electrician.
This appliance is for use on a nominal 120-V circuit and has a grounding attachment
plug that looks like the plug illustrated in sketch A in Figure 20. Make sure that the
appliance is connected to an outlet having the same configuration as the plug. No
adaptor should be used with this appliance.
MAINTENANCE
Lubrication of this motor is not required as it is equipped with sealed bearings.
Always keep the air cooling intake screen free, not allowing any restriction of airflow. Airflow restriction will over and
damage the motor.
To prolong the life of the HEPA filter, empty, clean, and replace bags and filters regularly as described in the
following sections.
STORAGE
Before storing your Nikro vacuum disconnect from electrical outlet.
The tank should be emptied and cleaned.
The cord should be coiled and stored so as not to create a tripping hazard.
The vacuum should be stored indoors.
