1.2. Water Flow Requirements
ThestandardresidentialAIRaiderTMSystemsaredesignedforusewithwaterowsupto20gallons
perminute(GPM).*Thesystemcomesequippedwithanoutowballvalve.Ifhigher/lowersystem

preventthisfromoccuringthewaterowratemustbedeterminedbeforethesystemisinstalled.
*Some AIRaiderTM Systems are not recommended for high ow residential properties. All repressurization systems
(except for the AIRaiderTM EZ95,433-S50 & 433-S50X) are sold separately. Proper repressurization system
sizing is required to meet water ow needs. Consult manufacturer if assistance is needed for system selection.
 Inordertodetermineavailablewaterowratethefollowingisneeded:
  •GardenHose

  •AStopWatchorWatchwithaSecondHand
Or
  •AWaterFlowMeter
Household water use must be discontinued during the following ow rate test.
Mid-Range Flow Rate Test:

thewatersupply.For optimal removal of radon or other VOC’s, other contaminants such as iron or
manganese must be removed before the water supply enters the AIRaiderTM System. Installation of
a sediment lter is highly recommended as a pre-treatment of the water supply. The lter should
be routinely cleaned or replaced.
FAILURE TO REMOVE OTHER CONTAMINANTS INCLUDING SEDIMENT CAN REDUCE
SYSTEM EFFECTIVENESS AND MAY RESULT IN SYSTEM DAMAGE , COMPONENT MALFUNCTION,
PROPERTY DAMAGE, AND PERSONAL INJURY.

9. Install Overow Protection and Alarm Prior to Use.
It is recommended that a Flood Stop (P/N 28276, sold separately) be installed prior to use of
this system to provide point of leak detection, whereby a motorized ball valve will
automatically shut o the system and prevent potential overows should debris clog
a shut-o valve. A basement water alarm also should be installed to warn residents of
water tank overows.
SAFETY TIP: Do Not undertake any step for which
you are Not Qualied.

Note: Short horizontal pipe run from system outlet to pump inlet is optimal. If this
pump location is impractical because of space constraints the pump may be located
remotely at a higher location, but pump lift, pipe diameter, and equivalent pipe length
must comply with limits specied in the pump installation instructions.
Do not mount pump lower than shown as removal of the pump for
service may result in tank contents siphoning out onto the oor!

Do Not Aempt to Adjust the Pressure on 433-S50 or 433-S50X Systems, as this may result
in the pump not shuing down as it aempts to reach too high a set pressure. This problem
may not occur immediately but can occur later when a low voltage supply occurs due to high
electrical demand or other external factors. The factory pressure seing is deliberately less
than maximum to provide an allowance for a low voltage supply event. Continuous
operation of the pump when there is no water demand will overheat the system causing
the thermal overload to trip and consequent pump shut down.
Note: Priming process for the jet pump and pressure seings may vary with repressurization system.

3. Retesting
AftertheAIRaiderTMinstallation,theinstallershouldperformanotherwateranalysistoensure
propersystemperformance.Thissampleshouldbeperformedoneweekafterthedateofinstallation.
Sampling Procedure:
1.Removeaeratorfromfaucetorspigot,ifapplicable.
2.RunwatersothattheAIRaiderTMoperatesfortwocycles.
3.Turnowaterfor5minutes.
4.Turnwateronandproceedwithsamplingasperthelaboratoryinstructions.
4. Maintenance
PropermaintenanceoftheAIRaiderTMcanpreventpossiblesystemfailureandprovideyearsof
trouble-freeservice.
4.1. Six Month Service (recommended)
ThefollowingproceduresshouldbefollowedtomaintaintheAIRaiderTM:

installations with particularly high levels of sediment, cleaning of lters may be required
more frequently.
•Checkandcleaninletscreenonpump.
•Usingawet/dryvac,cleansedimentfromboomofaerationtankifnecessary.
•Clean(ifnecessary)tankanddiusersofallmineralbuildup.

•Checkallcontrolpanelconnectionsandelectricalcomponents(blower,pump,timer,fuses,etc.)for
properoperation.
• Check oat switches for proper operation.
•Inspectventlineforpossibleobstructions.
•Runsystemthroughtwocyclestoensuregoodworkingorder.
