1. PRE-INSTALLATION
The AIRaider™EZ95 System is a diused bubble aeration system for the removal of radon and other VOC’s from
residential water supplies. This installation and operation manual is designed to guide professionals through
the safe and proper installation of the AIRaider™EZ95 System.
Before beginning the installation of the AIRaider™EZ95 System, there are 5 items to be considered. They are:
1. Safety
2. Installation site requirements
3. Inspection of System components
4. Qualied Technicians are necessary
5. Knowledge of all contaminants in the water
1.1. Safety Matters
Safety is the most important step in the installation process. Never perform any step of the installation that you
are not qualied to perform (i.e. Electrical or plumbing hook up). It is important that you read through the
entire manual prior to beginning the installation.
When performing the installation, work slowly and deliberately. Follow all instructions carefully and never take
shortcuts. Our team of technicians is available to answer your questions at 800-355-0901.
WORK SAFELY!

IN052 Rev. K 0613
1.2. Water Flow Requirements
The AIRaider™EZ95 System is designed for use with water ows up to 7 gallons per minute (GPM)* for
optimum Radon Reduction. Higher outow can be accommodated although higher ows will result in reduced
water pressure (see Figure 1) and a degradation of radon reduction ecacy.
If higher or lower system outow is needed, a ow control valve may be placed in the outlet piping down
stream of the bladder tank and may be opened or closed by the amount necessary to balance the system.
To avoid interruptions in the outow from the AIRaider™ EZ95 System the well pump output must exceed the system
outow by at least 1 GPM at design ow (i.e. well output = 8 GPM ; AIRaider™ EZ95 outow setting = 7 GPM).
If the well pump output is less than the system output the AIRaider™ EZ95 may run dry which will cause the
pump, installed integrally within the AIRaider™ EZ95 System, to automatically shutdown. To prevent outow
interruptions it is strongly recommended that well pump water ow rate be determined before the AIRaider™
EZ95 System is installed and that the system is balanced accordingly.
*The AIRaider™ EZ95 System is not recommended for high ow residential properties. Other AIRaider™Systems
are designed specically for high ow residential properties. Separate repressurization systems are not required
with the AIRaider™ EZ95 System but are available for other AIRaider™ Systems. Proper repressurization system
sizing is required to meet water ow needs. Consult the manufacturer if assistance is needed for system selection.
In order to determine available water ow rate the following is needed:
• Garden Hose
• Five Gallon Bucket
• A Stop Watch or Watch with a Second Hand
Or
• A Water Flow Meter.
Figure 1 - Pump Curve
PRE-INSTALLATION

Page 5 of 22
IN052 Rev. K 0613
Mid-Range Flow Rate Test:
1. Attach garden hose to the drain connection on the base of the Well Pressure Tank.
2. Open the drain valve and run water for 15 minutes.
3. After 15 minutes, check the pressure gauge on the well system. Adjust the drain valve (open or
close) as needed to maintain the required running system pressure (constant pressure on gauge)
with the well pump running continuously.
4. Run for 5 minutes while ensuring that the pressure is not uctuating.
5. Run water from the hose into a ve gallon bucket. Using a stop watch, time how many seconds it
takes to ll the bucket (Z sec.).
6. Determine the GPM by dividing 60 seconds by the number of seconds it took to ll the bucket (Z
sec.). Multiply the answer by 5 gallons. This gives you the GPM.
GPM = ( 60 / Z ) x 5
7. Repeat steps 5 and 6 and average the 2 numbers. The answer is the well pump output in gallons per
minute. It is recommended that this number be indelibly recorded in an obvious location, together
with the date of test, as it will be required when setting the AIRaider™EZ95 System and may be re-
quired for future troubleshooting of the well pump system or the AIRaider™EZ95 System.
Failure to remove other contaminants can reduce the eectiveness of the system and may result in system damage!
1.3. Full Water Test
A full Water Sample Analysis must be performed to determine the quality of the water that requires treat-
ment. In many water supplies, contaminants other than radon are present. The AIRaider™EZ95 System
is only eective for the removal of radon and some other VOCs. The Aeration Process employed by the
AIRaider™EZ95 System and other radon removal systems can worsen problems due to iron or manganese
contaminants in the water supply. For optimal removal of radon or other VOCs, other contaminants such as
sediment, iron, or manganese must be removed before the water supply enters the AIRaider™ EZ95.
1.4. Unpacking and Locating System Components
1.4.1. Unpack All System Components
Remove all packing material and discard appropriately away from the work area.
1.4.2. Locate All Components
Check to ensure all components are intact and included in shipment.
Included Component List (may vary with order)
• Tank Assembly
• Pump (Installed Inside Tank Assembly)
• Diuser Assembly (Installed Inside Tank Assembly)
• Bypass Valve (Sold Separately)
• Bladder Tank (Minimum 5 gallon. Sold Separately)
• Manual
Household water use must be discontinued during the following ow rate test.

2.2. Preparing the System for Installation
1. Remove fasteners securing cover to tank and
remove cover assembly. (See Figure 3)
2. Remove lid
3. Remove any packing materials, manuals, bagged
parts etc., from inside the system.
4. Check that the diuser assembly is mounted in
the elbow at the bottom of the front most pipe
on the right of the tank and is secured via the
mounting screw located vertically thru elbow
and horizontal diuser pipe.
5. Ensure that pump oat, is free to oat over the
diuser bar.
6. Check that all liquid tight connectors on cables
above the mounting plate are secure.
7. Check that all hose clamps on all oats and vent
pipe are tight.
8. Verify oat distances from mounting plate and
cable lengths from tether to oat are correct.
9. Mount the lid and lid gasket, do not secure with the fasteners provided at this time.
10. Replace the cover assembly, do not secure with the fasteners provided at this time.
2.1. System Location
When selecting the location for the AIRaider™EZ95 System, six factors should be among those considered:
1. System Plumbing Hook-up. Find a location that will minimize the amount of plumbing necessary, this
is typically in proximity to the well tank.
2. Electrical Hook-up. Keep in mind the need for accessibility to a 20 Amp dedicated 120VAC power
supply.
3. Exhaust Line Venting. The location of the system must allow for outside venting of the system exhaust
above the eave of the structure. The Manufacturer requires that the exhaust pipe pitch-back toward the
system (see Section 2.5).
4. Remote Air Intake. If the system must be installed in an area with questionable air quality (i.e. furnace
room, garage, crawlspace) then ducting from the air intake to a remote location having good air quali-
ty may be required.
5. System must be Level. The system should not be located on a signicant slope as this may impede
system performance and may cause system damage.
6. Drain Location. The system is equipped with an overow connection, it is recommended that this
connection be directed to a drain or sump.
Place the system in the location acceptable to customer that maximizes the ease of installation. All Local and
State codes as well as any applicable AARST, EPA and/or State Radon standards must be adhered to when
locating the AIRaider™ (i.e. away from electrical panel, furnace, exits, etc.).

2.3. Plumbing Hook-up
All plumbing should be performed in accordance
with Local and State Codes by a Qualied Plumber.
1. Shut o water main valve located after the pres-
sure tank.
2. Drain water line.
3. Plumb system into water line after the pressure
tank and all other water treatment equipment.
(Exception: Install before activated carbon lter/
tank.)
4. Plumb appropriately to “Water In” and “Water
Out”. (Figure 6)
For ease of installation and servicing a ¾” sharkbite
tting is provided on the inlet. This is compatible
with 3/4” pex or copper tubing.
5. From the open leg of the inlet tee run pipe/tubing
thru a bypass valve to a second tee.
6. Plumb unit as shown in Figures 6, 7 and 7a. The
Bladder Tank must be connected to the Rise Leg
of the Tee provided on the System Outlet, without
any elbows between the Tee and Tank.
Warning: An undersized bladder tank will result in
premature pump failure.
Note: Pipe supports are required, particularly to
support the bladder tank. These are not shown, as
installation details vary by property.
7. Plumb the water line to the house into the open
leg of the second tee. (Figure 7) It is recommended
that a ow control valve be installed in this line.
8. The built-in pump pressure switch and pressure
regulator provided are designed for use with a
pressure tank. The pressure tank bladder pressure
should be set per the tank manufacturers recom-
mendations for a pressure switch setting of 37 psi.
9. An outlet pipe must be installed in the overow
connection (gure 6) and connected to drain or
sump in accordance to Local and State Codes.
Warning: Overow may occur due to a blocked vent
pipe, debris in or wear of the solenoid valves, or incorrect
connection to the electrical supply. Failure to connect
the overow to a drain or sump (with sump pump or
other means of external discharge) may ood the area
around the unit in the event of overow occurring.
10. With the system in bypass mode, slowly open the
main water valve and check for leaks.
11. Remove tank cover and slowly change bypass
valve to service conguration and check for leaks.

2.4. Electrical Hook-up
The Installation must comply with the National Electrical Code, NEC NFPA 70 and all applicable Local and
State Codes! Electrical Wiring must be completed by a qualied and licensed electrician.
1. Turn main power switch, located on electrical box at rear left of unit, to the “O” position.
2. Bring power into the electrical box via the hole provided.
3. Connect power line to the connections provided within the electrical box per the Electrical Schematic
(Figure 8).
Warning: Line L1 must be connected to the switch connection. Do Not connect L1 to the white Neutral wire.
This will cause the Aeration System to malfunction.
4. Ensure that the “red” lead, provided for an optional auxiliary fan, remains insulated if not used. The
“red” lead is the live feed from the Aeration System to the Fan.
Warning: Do Not connect any of the Fan Leads to a separate power source. This will cause the Aeration
System to Malfunction
5. Connect power line to power source *. The AIRaider™ EZ95 System requires an 115VAC 20amp supply,
as marked on the system name plate, which is found on the rear left hand corner of the tank. Follow all
code requirements regarding wire and circuit breaker size.
* Manufacturer recommends that the AIRaider™ EZ95 System be directly wired to the panel on a dedicated circuit.
WARNING: Never perform electrical work while standing in water. Do not attempt
wiring on a live circuit.
WARNING: Power Supply Voltage must match that marked on the System Name Plate.
Improper wiring may result in system and/or property damage.

Page 13 of 22
IN052 Rev. K 0613
2.5. Vent Line Installation
Use only 2”, 3” or 4” Schedule 40 PVC or equivalent pipe
for vent line. Follow all applicable AARST, EPA, and/or
State Standards for Radon or VOC venting.
1. Connect vent line to 2” socket elbow on the rear of the
system (gure 9). Use PVC cement in a fashion that ensures
no leakage will occur. Note: A rubber coupling permitting
disconnection of the system from the vent line for future
maintenance is provided beneath the cover.
2. The vent line must be mounted in a fashion that allows the
system to exhaust above the level of the roof (Figure 10).
3. The vent must be pitched back towards the system to ensure
that any condensation runs back into the unit. If an optional
inline auxiliary fan is used, recommendations regarding
pipe pitch in the fan installation instructions must be strictly
adhered to.
4. If an optional auxiliary fan is used then the fan must be
wired to the system electrical box, connections as shown in
the Electrical Schematic (Figure 8). This will ensure that the
fan operates only when required by the system. The “red”
lead is the live feed from the Aeration System to the Fan.
Warning: Do Not connect any of the Fan Leads to a separate power
source. This will cause the Aeration System to Malfunction
5. Install weather cap on top of the vent line. This cap should
not restrict air ow and must prevent rain, snow and other
contaminants from entering the vent line.
Failure to install a proper vent line may cause
contamination of the water, outgassing of
contaminants into the building, limit system
performance and/or cause the system to
overow.
NOTE: The Manufacturer has found that vent lines less than 250
equivalent linear feet do not cause a decrease in contaminant
removal percentages. 90° Bend = 15 Equiv. Linear Ft ; 45° Bend =
7 Equiv. Linear Ft. An inline auxiliary fan is recommended if the
vent line exceeds 250 equivalent linear feet.

2.6. Remote Air Intake
If a Remote Air Intake is required because of Air Quality or Quantity issues then Use Only 1-1/4” or larger
Schedule 40 PVC or equivalent pipe for the air intake line.
1. Unscrew the air lter provided from the cover and run the intake line from the pipe thread
connection on the cover to the location selected for the air intake.
NOTE: A rubber coupling or similar means to disconnect the intake line from the AIRaider™ must be provided so that
the AIRaider™ cover may be removed for start-up and maintenance.
2. Connect the air lter previously removed to the intake end of the intake line.
If the air intake is located outside, the intake must be mounted high enough to prevent the drawing in of snow, water and
other contaminants. Do not locate the air intake in the vicinity of vents from furnaces, barbecue grills, etc.
2.7. System Start-Up
1. Remove cover and lid and pour ¼ cup of chlorine into the AIRaider™ tank. (This will disinfect the
system.) Secure the lid with the screws and washers provided.
2. Check that all plumbing and electrical connections have been properly completed.
3. Slowly change bypass to the “service” conguration. Check for leaks.
4. Turn power switch for AIRaider™ to “On”. Solenoid valves will now open allowing water into the
system. The aeration process will also start. Check for leaks.
5. Allow the AIRaider™ to ll with water. The aeration process will stop. The pump will self prime
during the ll cycle. There is an orice behind the left side of the pump which allows the pump to
prime. This orice will spray water into the aeration tank whenever the pump is running. The orice
is sized for the minimum ow specied for the pump. (The pump will fail to prime if the orice is
blocked). The pump will start and will continue running until the house water system is pressurized.
Check thoroughly for leaks around all pipe joints, etc., and seal if required.

IN052 Rev. K 0613
2.8 System Check
1. Run the system through a couple of
cycles to ensure all components are
working properly.
2. e blower operates for the duration
of the ll cycle. e blower should
shut o when the ll cycle ends.
3. If the blower fails to operate, the
alarm buzzer will sound. e alarm
buzzer will also sound if the lower
oat fails to operate. e function
of the alarm buzzer can be checked
by removing the blower fuse on the
rear of the blower enclosure while the
blower is running.
4. If the pump does not continuously
supply water under maximum out-
ow conditions, the outow from the
AIRaider™ EZ95 probably exceeds the
well pump output previously deter-
mined in Section 1.2. is may
be remedied by closing the ow control valve, at maximum demand, until continuous output
is obtained. For optimum radon removal the outow should be adjusted to the value given in
Table 1 for the measured well pump output. is is done by temporarily attaching a hose to the
house connection of the bypass valve and adjusting the ow control valve to provide the correct
ll time for the 5 gallon bucket used to determine ow rate (or the correct ow rate if using a
ow gauge).
5. Replace the cover and secure with the fasteners provided. With the system running check the
cover for air leaks between gasket and cover. If leaks occur the gasket may need to be repositioned
and fasteners retightened.
6. Make sure you have properly labeled the system with the necessary installer information (i.e.
company, name, phone #, date installed, etc.) and have le all system information with the
home owner.
