The Phoenix Guardian R HEPA System is the most compact,
portable unit in our popular line of high performance
airscrubbers. The Phoenix Guardian R features a 22” x 24”
footprint and stands only 14” tall. Weighing less than 35 lbs
and featuring a molded handle and stackable design, the
Guardian R is easy to carry, transport, and store.
For maximum flexibility, the Phoenix Guardian R features
variable airflow and can be operated vertically or
horizontally. The Guardian R is designed to accept 16”
inlet flex duct and 10” lay flat outlet duct for a variety of
operating set-up options.
The Guardian R delivers a maximum 500 CFM of HEPA
filtered air, while drawing less than 2.3 amps of power. This
makes the Guardian R HEPA System perfect for a variety
of remediation projects where space and power are at a
premium. A single Guardian R is capable of providing 4 air
changes per hour (the recommended minimum) on a 7500
cubic foot room (more than a 30’ x 30’x 8’).
The Guardian R HEPA System’s 2-stage filter design - with
documented true HEPA filtration performance - will remove
hazardous particles from the air and, with the addition of an
optional carbon/potassium permanganate filter, will adsorb
a wide range of odors and gases.

3 Operation
3.1 Transporting the Phoenix Guardian R
The power cord may be stored by wrapping it neatly around
the duct collar or stowed below the circular foam inlet cover.
In either case rotate the four small stainless steel locking
tabs 90° for transport of your Guardian R
The Guardian R should be transported vertically or
horizontally on the appropriate feet located on the bottom of
the unit or opposite the handle.
3.2 Electrical Requirements
The Phoenix Guardian R HEPA System can be plugged into
a grounded 15 Amp circuit. It draws about 2.4 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 unit
must be plugged directly into a wall outlet. No extension
cords should be used.
3.3 Air Ducting
3.3A 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 circumference at one location and working it
over the lip gradually. Ducting can be locked into position
by reaching through collapsed ducting to rotate locking tabs
90°. It may be removed after use for easier transport and
storage. Flexible 16” duct is available from Therma-Stor LLC.
(4028357)
3.3B Outlet Ducting
A detachable trapazoid shaped exhaust ring is supplied that
will allow 10” round lay-flat plastic duct to be attached to
the Phoenix Guardian R HEPA System outlet. Lay-flat plastic
ducting is available from Therma-Stor LLC. (4024935)
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.
3.3C Negative Air Ducting
The Phoenix Guardian R HEPA System can be used to filter
and exhaust air from a space. When exhausting to outside,
the space will be under a slight negative pressure. This will
help prevent airborne particles from leaving the space, as
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, fireplace or water heater)
can cause those devices to backdraft. This can contaminate
the space with potentially fatal gases.
In such cases, the Phoenix Guardian R HEPA System 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 Phoenix Guardian R
HEPA System is running.

C. Direct the outlet duct from the Guardian R HEPA System
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
Guardian R HEPA System is running to guarantee that
they are not backdrafting.
3.4 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.
3.5 Resettable Circuit Breaker
The 12 AMP thermal response resettable circuit breaker
protects the unit and devices connected to its duplex GFCI
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 Guardian R on-board circuit breaker prevents
nuisance visits to a remote power junction box.
Note: The holes on the control panel plate allow the
pressure inside the control panel to equalize with ambient
air pressure.
IMPORTANT: Total amperage of the Guardian R 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.
IMPORTANT: When the Phoenix Guardian R is plugged into
a standard “powered” wall outlet the Phoenix Guardian R’s
duplex outlet is electrically “HOT” and AC voltage is present.
3.6 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
Guardian R 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.
3.7 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 Phoenix Guardian R is first turned on, check for
excessive vibration. If the unit vibrates excessively or if
impeller rubs on housing, turn off the unit immediately. Have
a service technician inspect the unit to locate the problem.
4 Maintenance
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.
4.1 Air Filters
The standard Phoenix Guardian R HEPA System 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. 30 to 35% efficient (per ASHRAE 52.1-1992), MERV-7,
pleated fabric pre-filter.
B. 99.97% DOP efficient HEPA filter.

4.2 Filter Replacement
4.2A Filter Change
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 500
CFM performance.
Airflow on high speed with all filters clean and no ducting
is slightly over 500 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. 500 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:
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.
4.2B Optional Activated Carbon/Potassium
Permanganate Filters
Optional gas phase filters are available from Therma-
Stor. They 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 damage.
The life of the media blend depends upon both the hours
used and the contamination level. Another 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.
