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.
Additional filters can be purchased. Please contact your
AIRPHX representative at 855-424-7749 or visiting our
online store - https://www.AIRPHX.com/shop
If further assistance is required, please contact your AIRPHX representative at 855-
424-7749 or visit our website https://www.AIRPHX.com/FAQs, where additional

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.

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

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.

9 Installation Procedure
Procedure:
In the example below, a bolt, flat washer and wing nut are used to secure the wall
mount bracket to a drywall surface.
1. Find a central location for the PA2400 in the area you would like to treat. Be
mindful of any obstructions that may be within the wall.
2. Using painter’s tape, tape the provided installation template to the wall.
3. Utilizing a level, check to make certain that the template is level by placing a
level on the level line located on the top of the template.
4. Using a punch, mark all four mounting holes for the wall mount bracket.
5. Drill each hole using a ¾ drill bit.
6. Insert each bolt through a flat washer and into a wing nut. Thread the wing
nut on the bolt far enough that it will not fall off the bolt during installation
as shown in fig 1.
7. Insert all four wing bolt assemblies into the holes. Make certain that the
wings nuts have expanded and that all four wing bolts and flat washers are
sticking far enough out of the wall that the wall mount bracket can be hung
on them as shown in fig 2.
8. Hang the wall mount bracket on all four wing bolts with the flat side of the
bracket towards the wall as shown in fig 6.
9. Tighten all four wing bolts to secure the bracket to the wall. Using a level on
the bracket make certain that the bracket is level before completely
tightening the bolts as shown in fig 3.
10. Hang the PA2400 on the wall mount bracket by lining up the four enclosure
bolts with the mounting holes in the bracket as shown in figures 4 and 5.
11. The easy mount bracket has four “V” slots that will self-guide the PA2400
into its correct position on the bracket as shown in fig 6.
12. The installation is complete. The PA2400 can be plugged in and turned on.

13 Testing – Replacement of the Plasma Chamber
The Active indicator on the PA2400 is illuminated red.
If resetting the filter does not clear an Active indicator that is illuminated red, this
is an indication that the plasma chamber monitoring circuit has detected a fault
within the plasma chamber. There are several factors that can cause a fault.
Exposure to high humidity, cleaning solvents, an AC power issue or a foreign
substance that has built up on the plasma cell itself. This can be a temporary issue
or one that requires the replacement of the plasma chamber. The plasma chamber
is designed to be easily replaced without removing the PA2400 from the wall.
A Temporary Issue
Before replacing the plasma chamber, it is a good idea to identify whether it is a
temporary issue or one that requires the replacement of the plasma chamber. If
this is a new install and the PA2400 was working without issues for several days
before the Active indicator illuminated red, the problem is more than likely
temporary.
A common reason for the Active indicator to illuminate red is the need to reset the
filter function. With the unit powered on, press and hold the filter reset button
located on the front of the unit, for 15 seconds. If this is the issue, the Filter
indicator will change from red to green and the unit will startup. If the condition
does not clear, see below.
An Issue Needing Replacement
If your PA2400 has been installed for several months or years and the Active
indicator has illuminated red and you have tried the option above, it may be time
to replace it. Over time, the plasma chamber can collect foreign substances that
can cause it to fail. This is more than likely due to an environmental factor or
something that was recently introduced into the plasma chamber.
To obtain a replacement plasma chamber, please contact your AIRPHX
representative at 855-424-7749.

14 Plasma Chamber Replacement Process
1. Turn off and unplug the PA2400.
2. Carefully remove the replacement plasma chamber from the box it was shipped
in. Note – The plasma chamber contains glass elements and is very fragile. If the
shipping box or plasma chamber looks damaged, please contact your AIRPHX
representative for a replacement.
3. The plasma chamber is held in place by its exhaust grill located on the top of
the unit. The grill needs to be removed in order to gain access to the plasma
chamber.
4. Using a small flat blade screwdriver, loosen all four screws that secure the
exhaust grill in place. Note - The screws will remain within the grill housing once
removed. Refer to fig 1B.
5. The grill can be removed once all four screws have been completely loosened,
refer to fig 1C. If you find it difficult to remove the grill, check to make certain
that all four screws have been completely loosened.
6. The plasma chamber (tube) will be exposed once the grill is removed. Grasp the
end of the tube and pull it straight up and out of the unit. Note - The plasma
chamber has two contact points located at the bottom of the tube. These two
contact points need to align with the two notches in the grill base in order to
remove the plasma chamber. Refer to fig 1D.
7. Note - when installing the new plasma chamber, make certain that the notch
cut into the top of the plasma chamber is aligned with the front of the unit as
shown in fig 1C.
8. With the new plasma chamber in hand, align the contacts on the plasma
chamber with the two notches in the grill base, refer to fig 1D.
9. Keeping the plasma chamber in a straight orientation, lower it slowly into the
unit. You will feel the plasma chamber come to a stop once it is in its contact
socket. If resistance is felt during this process, you may want to open the front
door to the PA2400 to help guide the plasma chamber into its socket.
10. Replace the exhaust grill taking note of the alignment arrows as shown in Fig
1F.
