INSTRUCTION MANUAL
MODEL #HD55345
TRI-MOTOR HEPA VACUUM

____
INDUSTRIES, INC.
--------WARNING--------
All Nikro Industries Inc. products that have rated efficiencies of 99.97% @ 0.3 microns and 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 machine is equipped with a grounding type cord and three
prong plug. Make sure that the plug is connected to an outlet with
three receptacles designed for use with the three-prong plug. (See
Illustration) Never use an adapter with machine.
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 overheat and damage the motor.
To prolong the life of the H.E.P.A. filter, empty, clean, and replace bags and filters regularly as described
in the following sections.
SAFETY INSTRUCTIONS
Read all safety instructions before using!
1. Electrical shock could occur if used outdoors or on wet surfaces.
2. Always store machine indoors in a dry area. If machine is dropped in water or left in rain, it should be
serviced by an authorized service technician prior to plugging the unit in.

11. Do not operate this machine with any of the openings blocked; always keep these areas free of lint and
dust or any other particles that could reduce the airflow.
12. Never operate or plug in this machine or any other electrical appliance with wet hands or when
standing in water.
13. This machine should never be operated without the proper filters installed in the manner described in
the following pages of this manual.

FILTER MAINTENANCE AND REPLACEMENT INSTRUCTIONS
Your Nikro vacuum has a five stage filtration system; Non-clinging Dacron bag filter bag,
Canvas filter bag, Polyester Prefilter, Impaction filter, and HEPA Filter. These filters should be
inspected every time the tank is emptied or when a significant loss of vacuum power is detected.
If a decrease in vacuum power is detected, turn off the vacuum immediately. (WARNING:
Continued use could cause serious damage to motor and or HEPA filter.) This loss of vacuum
power could be caused by one of the following:
a) The tank may be full and needs to be emptied.
b) The Dacron filter bag may be clogged and needs cleaning.
c) The canvas filter bag may be clogged and needs cleaning.
d) The polyester prefilter may be clogged and needs to be cleaned or replaced.
e) The impaction filter may be clogged and needs to be replaced.
t) The HEPA filter may be clogged and needs to be replaced.
g) The wand, hose, or intake may be clogged and needs to be cleaned.
PROCEDURES FOR REMOVING CONT AMINATED FILTERS
Caution:
When removing contami5ated filters or using this machine, you should always wear gloves,
clothing, and a respirator approved for use with the particular contaminant you are working with.
FILTER REMOVAL PROCEDURES
1. Turn off and unplug machine.
2. Slowly and carefully lift one side of the lid assembly from the tank. Holding the lid with one
hand, reach under the lid and gently tap all around the Dacron bag, allowing any dust
particles to drop into the tank.
3. Carefully lift the lid assembly off the tank. With a damp rag, wipe the underside of the lid
assembly. Set it aside and dispose of the rag properly.
4. Carefully remove the Dacron filter bag from the tank. This filter bag can be washed and
reused.
5. Remove the 6 mil. breather bag. This bag can be removed by gathering the top of the bag
together, hold bag just below breather holes and lift out of tank. This bag can be tied or taped
below the breather holes.
6. Unhook the canvas filter bag clamp and slide the bag off the lid assembly. This filter bag can
be washed and reused.
7. Carefully unfasten the Velcro from the polyester prefilter and remove it from the HEPA
filter. This filter can be washed and reused or discarded when material begins to separate or
fall apart.
8. Remove the impaction filter and discard it.
9. Take a damp rag and wipe down the inside of the tank. Dispose of contaminated rag
properly.
10. All hazardous waste material must be disposed of properly. Never put contaminated debris in
a regular trash container. All debris must be placed in a plastic bag or container labeled
"Hazardous Materials", and should be removed by a licensed hauler. Consult proper
authorities on disposal regulations.

FILTER SET-UP PROCEDURE
1. Place HEPA filter on lid, making sure the airflow arrows are pointing towards motors
