To reduce the risk of electric shock:
• Do not expose to standing water or rain
• Connect to GFCI outlet
• Do not use an extension cord
• Unplug fan before servicing or changing filters.
• Do not block air intake or outlet. One foot minimum distance to obstructions.
Indoor use only
• Do not use as stool or bench
• Do not operate with damaged cord or plug.
• Do not run cord under carpeting.
• Do not cover cord with throw rugs, runners, or similar coverings.
• Do not route cord under furniture or appliances. Arrange cord away from traffic area and
where it will not be tripped over.
Operation
Transporting the PA-600-HAS
The air scrubber should be transported vertically or horizontally on the appropriate feet located
on the bottom of the unit or opposite the handle.
Electrical Requirements
The PURAERO PA-600-HAS System can be plugged into a grounded 15 Amp circuit. It draws
about 2 Amps with clean filters and no ducting. The amp draw will decrease slightly with added
ducting and as the filters load with particulate. Due to the presence of GFCI receptacle, the
PA-600-HAS must be plugged directly into a wall outlet. No extension cords should be used.
Air Ducting
Inlet Ducting
Occasionally the area to be filtered is difficult to access and/or the unit cannot be located in the
area. In such cases, the air can be ducted to the unit's inlet. A round 16"diameter flexible duct can
be attached to the unit inlet. It connects by placing the wire in the duct over the duct collar lip at
one location and working over it over the lip gradually. It may be removed after use for easier
transport and storage.
Outlet Ducting
A detachable trapazoid shaped exhaust ring is supplied that will allow 10"round lay-flat plastic duct
to be attached to the PA-600-HAS outlet To attach ducting to the collar, remove the ring from the
unit by pressing release tab at the top of the grill. Put the plastic duct end through the inside of
the ring. Roll the duct end outward so that it over-laps the outside of the ring. Clip the ring back
onto the exhaust grill.

Negative Air Ducting
The PA-600-HAS can be used to filter and exhaust air from a space. When exhausting to outside
the space, the space will be under a slight negative pressure. This will help prevent airborne
particles from leaving the space, because the negative pressure will draw air in through openings
in the space's exterior surfaces.
CAUTION :Exhausting too much air from a space with open combustion devices(e.g. furnace, fire
place or water heater)can cause those devices to backdraft. This can contaminate the space with
potentially fatal gases.
In such cases, the PA-600-HAS must be used in one of the following three ways:
A.As a filtering unit only. Exhausting no air from the space and thus causing no negative pressure or
backdrafting.
B. Exhausting a very limited amount of air which does not cause backdrafting. In case B, the open
combustion devices must be thoroughly checked to guarantee that they do not backdraft while the
air scrubber is running.
C. Direct the outlet duct from the air scrubber to the room with the open combustion device(s).This
will positively pressurize the room with HEPA filtered air, thus preventing backdrafting. As in case B,
those combustion devices must be checked after the air scrubber is running to guarantee that they
are not backdrafting.
Power/Speed Control
The power/speed switch is located on the control panel. When turned on to any speed. it powers
the impeller fan. Occasionally the impeller fan may not start on low speed. If this occurs, rotate the
speed control to high speed until the impeller fan starts, then adjust it to a lower speed.
CAUTION: Do not remove HEPA filter with the unit on. Removing the top and filters while
running will expose the dangerous rotating impeller fan. Disconnect the appliance before
changing filters.
Resettable Circuit Breaker
The 12 AMP thermal response resettable circuit breakerprotects the unit and devices connected to
its duplex GFCl outlet. The circuit breaker is designed to sense the total current draw through the
circuit. The circuit breaker "trips" when more than 12 amps of electrical current are drawn through
the device's power cord. Should an over-current condition occur, the PA-600-HAS on-board circuit
breaker prevents nuisance visits to a remote power junction box.
IMPORTANT: Total amperage of the PA-600-HAS plus all devices plugged into the receptacle
must not exceed 12 amps. The circuit breaker will not allow for loads in excess of 12 amps,
although there is a time delay before the overloaded circuit is broken. When the PA-600-HAS
is plugged into a standard "powered" wall outlet the unit's duplex outlet is electrically "HOT"
and AC voltage is present.
GFCI Protection and the On-Board Duplex VAC Outlet
The standard AC voltage outlet GFCI(Ground Fault Circuit Interrupter)protection promotes operator
safety in wet applications. GFCI devices trip when a fault to electrical "ground" is sensed. It is
recommended to check the GFCI protection prior to operation. To check, push the"TEST"
button located on the GFCI duplex outlet. If operating properly the "RESET" button on the GFCI

Page 3
outlet will pop out. A tripped GFCI is indicated by a small LED. The device can only be RESET
when the PA-600-HAS is connected to a wall outlet providing standard voltage. This duplex AC
outlet allows the inter-connection of other AC powered devices. The sum total amperage of all
devices plugged into the receptacle must not exceed 10 amps.
Servicing
Before each use inspect for damage, blocked inlet or outlet. Inspect the GFCI to ensure it is not
in a "tripped" condition. Push RESET to reset the GFCI. When the PA-600-HAS is first turned
on, check for excessive vibration. If the unit vibrates excessively or if impeller rubs on housing.tum
off the unit immediately. Have a service technician inspect the unit to locate the problem.
Air Filters
The standard PA-600-HAS is equipped with two filters that progressively filter out smaller particles.
An optional activated carbon/potassium permanganate filter can be also added. These filters must
be checked regularly. Operating the unit with dirty filters will reduce the airflow, but will do no harm
to the unit. The unit can be run indefinitely with dirty filters. The two standard filters used are listed
below(as installed in the unit from top to bottom):
A.25 to 30% efficient(per ASHRAE 52.1-1992),MERV-7.pleated fabric pre-filter.
B.99.97% DOP efficient HEPA filter.
Filter replacement
When the amber "filter change light" illuminates. It may be time to replace one or both filters
To check airflow accurately, an airflow meter or anemometer must be used:
When the filter change light illuminates; remove all ducting and run on high speed. If the filter light
remains lit; replace the pre-filter and run on high again. If the light remains: it is time to replace the
HEPA filter for full 650 CFM performance. Airflow on high speed with all filters clean and no ducting
is slightly over 650 CFM. The unit can be run with very dirty filters and virtually no flow without
harming the unit. The operator's decision to change filters should be based on filter cost vs. the
unit's filtering effectiveness. If airflow is 250 CFM vs.650 CFM, the unit will filter particles from a
space at half the rate. The operator must judge if that is acceptable.
If the operator determines the filters should be changed due to low airflow, it is most economical to
change them in the following order:
Change the pre-filter(top)first. This is the least expensive filter. Recheck the airflow. If the airflow is
acceptable, no other filters need to be changed.
Maintenance
WARNING! Use extreme caution when changing the HEPA filter as hazardous material could
be trapped in the media. Always make sure to dispose of filters in the appropriate way. If you
are unsure of how to safely dispose of any filter-consult an industrial hygienist to ensure that
all hazardous materials are contained and disposed of properly.

Page 3
If the airflow is still too low, the HEPA filter must be changed. To remove the HEPA filter, follow these
steps:
1.Loosen the eight screws one revolution
2.Rotate all eight clips out of the way.
3.Remove old filter.
4.Installing the new filter is the reverse of these instructions
Optional Activated Carbon/Potassium Permanganate Filters
Optional gas phase filters use a blend of activated carbon and potassium permanganate. This blend
removes the vast majority of gaseous contaminants encountered in most filtering applications. The
activated carbon removes the heavier volatile organics while the potassium permanganate removes
lower molecular weight contaminants. This is well suited to the smoke odors present after fire.
The life of the media blend depends upon both the hours used and the contamination level. Another
damage advantage of the blended media versus activated carbon only is that part of the blend
changes color as it loads up with contaminants. It starts out black, then turns pink, then brown, and
finally white .It is best changed when it passes the brown stage and begins to turn white. It has lost
most of its effectiveness at that point. The filter is the same size as the pleated fabric filter. Install it
in place of the pleated fabric filter.
Service
CAUTION: Servicing the PA-600-HAS with its high voltage circuitry presents a health hazard that
could result in death. serious bodily injury, and/or property damage. Disconnect the appliance from
the power supply before servicing. Only qualified service people should service this unit.
