3 Operation

3.1 Transporting the Phoenix GuardianR

The GuardianR 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 GuardianR HEPA 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 Pro model 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 at one location and working over it over the lip  gradually. It may be removed after use for easier transport  and storage. Flexible 16” duct is available from Therma-Stor

LLC. (4028357)

3.3C Negative Air Ducting

The Phoenix GuardianR HEPA System 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.

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 GuardianR 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.

1 2

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 GuardianR 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 GuardianR HEPA 

System is running.

C.   Direct the outlet duct from the GuardianR 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 GuardianR 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.

3 4

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 GuardianR on-board circuit breaker prevents nuisance visits to a remote power junction box.

IMPORTANT: Total amperage of the GuardianR 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 GuardianR is plugged into a standard “powered” wall outlet the Phoenix GuardianR’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 

GuardianR 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 GuardianR 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 GuardianR 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.  25 to 30% 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 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.

Toll-Free 1-800-533-7533 4 www.UsePhoenix.com • [email protected]

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

The photo depicts clip in a locked position. Turn screw counter-clockwise to remove.

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. 

5 Service

CAUTION: Servicing the Phoenix GuardianR HEPA System with its high voltage circuitry presents a health hazard that could result in death, serious bodily injury, and/or property damage.
