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 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.
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.
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.
If the airflow is still too low, the HEPA filter must be changed. To remove the HEPA filter, follow these steps:
- Loosen the eight screws one revolution
- Rotate all eight clips out of the way.
- Remove old filter.
- 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.
