This user guide contains basic information for the safe installation and operation of
the AIRPHX PA2400. The operation and installation of this equipment is the sole
responsibility of the end-user. Please read this guide in its entirety before installing
and operating the equipment.
The AIRPHX PA2400 is intended to treat areas with 250,000 cubic feet of air. In
smaller areas, the timer should be used to reduce the amount of oxidizing
molecules being released.
The AIRPHX PA2400 should never be exposed to liquids. If using cleaning products or
liquids near or around the unit, please turn the PA2400 off prior to cleaning.
Please follow all recommendations for the mounting and installation of the PA2400 unit.
If you have any question about the installation, please contact your AIRPHX
representative at 855-424-7749.
Find a central location for the PA2400 within the treatment area.
oAvoid locations with high humidity, like swimming pools, whirlpools, and showers.
High moisture levels can damage the PA2400’s plasma chamber.
oMount the unit at least four feet from an adjacent wall, and at least 2 feet from
the ceiling.
The PA2400 requires a standard 120-volt outlet. Please verify the following electrical
requirements prior to the installation of the PA2400 unit.
oVerify the voltage of the outlet. The PA2400 requires a standard 120- volt outlet
with a ground and draws only 1/2 amp, therefore it can be part of an existing
circuit.
oIf a new outlet is installed, please make certain that the outlet meets all local,
state and national electrical codes.
oVerify that the outlet is not part of a circuit that may be overloaded. Large power
fluctuations associated with overloaded circuits can damage the PA2400.
oDo not use a cord adapter that defeats the earth ground on the provided power
cord.
The filters on the PA2400 generally need to be replaced every 30 days. There is a Filter
indicator, located on the front of the unit, that will illuminate red as a reminder to change
the filters. Depending on the environment in the treatment space, it is possible that
filters may need to be changed more frequently.

2 Notice cont.
It is strongly recommended that you mount the AIRPHX PA2400 on a wall using the
enclosed hardware.
If you opt not to mount the unit on a wall, it may be placed flat on the back of the unit
with the LEDs and timer facing the ceiling. You will need to ensure that the top of the unit
where the air discharges is at least two feet from a wall or obstruction.
Never run the unit by just placing it upright on a shelf or other flat surface. Doing so will block a
cooling fan on the bottom of the unit and cause damage to the unit’s electronic components.
To protect against injury, it is recommended that all repairs to the PA2400 be performed
by qualified service personnel.
Do not introduce foreign objects into the unit’s intake or exhaust ports.
Keep the air inlets and outlets of the PA2400 clear of obstructions.
Do not expose the PA2400 to liquids. Please turn off the PA2400 prior to cleaning around
the unit.

3 Modes of Operation
The PA2400 has three modes of operation.
Run Mode: The power switch is in the ON position (switch will illuminate red). The
7-day timer switch is in the OFF position.
7-Day Timer Mode: Both the power switch and the 7-day timer switch are in the
ON position. In this mode, the PA2400 is controlled by the schedules programmed
within the 7-day timer.
Standby: In standby, the PA2400 7-day timer is on and the timer is in the middle of
an OFF-schedule program. The plasma chamber of the unit and the unit’s blower
are both off. The Active LED will not be illuminated green.
Please note that if the filter has not been changed within 15 days after the Filter
indicator illuminated red, the Active LED will illuminate red indicating the unit’s
plasma cell is off. At this point, the filter will need to be changed and the filter
reset procedure is required. Please refer to the section in this guide, Filter
Replacement and Reset Procedure for more details.
In both conditions, the unit will resume operations once the condition is cleared.

5 Status Indicators
The PA2400 has three status indicators located on the front of the unit.
Active Indicator:
This indicator illuminates green whenever the plasma cell is active, and the unit is
producing disinfecting molecules. It will illuminate red if a filter reset has not
occurred within the last 45 days or if a fault has been detected within the plasma
chamber. If this happens, please reset the Filter LED as explained in the Filter
Replacement and Reset Procedure section of this guide. If after resetting the filter,
the Active indicator remains red, refer to the section in this guide Testing and
Replacement of the Plasma Chamber for more details.
Note – It is normal for the blower to run while the Active indicator is illuminated
red. This helps remove any moisture from the plasma chamber.
Timer Indicator/Switch:
This indicator illuminates green when the unit is in the 7-day timer mode.
Filter Indicator/Switch:
This indicator will illuminate green at first activation of the PA2400. It will remain
green for 30 days at which point it will illuminate red indicating it is time to replace
the filter. If the filter is not replaced within 15 days of the indictor illuminating red,
the unit will go into standby until the filter is replaced, and the filter reset
procedure is completed. Please refer to the Filter Replacement and Reset
Procedure section in this guide for further details and instructions.

6 Filter Replacement and Reset Procedure
Filter Locations
1. Turn the PA2400 off.
2. Locate the 92mm intake filter on the left side of the unit. Note, each filter
has a grill that holds the filter media in place. This grill needs to be removed
in order to replace the filter.
3. Pull on the outer edges of the plastic grill carefully to remove it. A small
screwdriver can be used to help pry the grill from its retainer.
4. Replace the filter media.
5. Replace grill by carefully snapping it back onto its retainer. Make certain that
the filter media stays within the grill during this process.
6. Once all the filters are replaced, power on the unit. The Filter indicator will
still be illuminated red at this point.
7. To reset the Filter indicator, press the filter reset button located on the front
of the unit and hold it for 15 seconds. The Filter indicator will change from
red to green indicating the filter reset is completed. The PA2400 will resume
operation once this process has been completed.
Please note that if the reset button is pressed again after the reset procedure has
been completed or while the Filter indicator is green, the Filter indicator will
illuminate red and the unit will cut on and off as long as the reset button is held.
This is normal operation.
Please note that your unit may have a smaller 60 mm filter on the right hand side
of the unit. If this filter appears dirty, the plastic grill can be removed and the filter
can be discarded. There is no need to replace this filter.
