3.4.1.2 Replace Blue O-ring1. Turn the lid with locking ring upside down andplace it on a stable surface.2. Place the blue o-ring on the step located ¼" fromthe bottom of the lid. See Figure 8.3. Make sure that the o-ring is properly seated. Ithelps to “place” the o-ring on the step rather thanto “roll” it on. That prevents it from rolling off.NOTE The blue o-ring sits approximately ¼" awayfrom the seal. See Figure 8.4. Carefully install the lid, making sure that the bluepressure test o-ring sits in the housing without“binding” or “rolling” off.5. Following the markings on the locking ring,align ‘START’ markings with the ports and turnclockwise until ‘LOCKED’ markings align withthe ports. Do not tighten past the ‘LOCKED’marking.3.5 Conducting Pressure TestWARNINGWhen pressure testing a system with water, airis often trapped in the system during the fillingprocess. This air will compress when the systemis pressurized. Should the system fail, this trappedair can propel debris at a high speed and causeinjury. Every effort to remove trapped air must betaken, including opening the bleed valve on thefilter and loosening the pump basket lid while fillingthe pump.WARNINGTrapped air in the system can cause the filterlid to be blown off, which can result in death,serious injury, or property damage. Be sure allair is properly purged out of the system beforeoperating. DO NOT USE COMPRESSED AIR TOPRESSURE TEST OR CHECK FOR LEAKS.WARNINGDo not pressure test above 35 PSI. Pressuretesting must be done by a trained poolprofessional. Circulation equipment that is nottested properly might fail, which could result insevere injury or property damage.WARNINGWhen pressure testing the system with water, it isvery important to make sure that the pump basketlid is completely secure.1. Fill the system with water, using care to eliminatetrapped air.2. Pressurize the system with water to no more than35 PSI.3. Close the valve to trap pressurized water in thesystem.4. Observe the system for leaks and/or pressuredecay.5. If there are lid leaks, repeat Steps 1-3. Fortechnical support, call 800.822.7933.6. After successfully completing the test, discard theblue pressure test o-ring.3.6 Auxiliary Load OperationCertain pump models are equipped with a terminalbar that provides user access to a built-in AuxiliaryLoad relay contact. This normally-open, dry contactis activated under certain operating conditions and isprimarily intended to be used to control external devicesthat require system water flow for proper functioning,such as heaters, booster pumps, salt water chlorinators,etc.See Figures 4, 5A and 5B for compartment’slocation details. An access cover with Phillips-headscrew must be removed before proceeding.Upside Down View ofBottom of LidStep whereO-ring is SeatedGroove whereSeal is SeatedFigure 8.
