4.1.3 Mounting the pH and Redox sensors
Thesensors(notablytheRedoxsensor)shouldbemountedbeforethelterandtheheatingsystemsothat
sensorreadingsarerepresentativeofactualvaluesinthepool.Impuritiesaccumulatedintheltermedium
removeChlorinefromthewaterasitpassesthroughthelter,inaddition,Chlorinecanbedegradedon
contactwithheatingelementsandhotexchangerplatesintheheatingsystem.
Sensorsaremountedinhousings(seebelow)tobescrewedintothetappedoriceinthesensorhousing.
Thesensorfeedheadsshouldpointup.Theyshouldnotbelocatedata"high"pointofthehydraulic
circuittoavoidthembeingexposedtoairshouldairbeintroducedintothesystem.
Tostopthesensorsfrombeingdamagedbygravelorsand,theby-passvalvesshouldbesettoslow
theowofwaterthroughtheby-passcircuit.
Removethesensorsfromtheirstorageasksandinstallthemcarefullyinthepipeonly after the circuit
hasbeenlledwithwater.Keeptheaskstostorethesensorsintheeventthattheyareremovedfor
winterizing.
Sensor cables should not be run through sheaths containing other electrical cables, to avoid
interference.
4.1.4 Mounting the pH reducer injection pump
Thesuctionandinjectiontubesare2mlong.
Respectthemax.suctionheightbetweenthepumpandthepHreducertank:1.5 m max.
Insertoneendofthetubeintheconnectionlocatednearthecellheadandtightenthe1/2"barrelunion.
Theotherendshouldbeplacedatthebottomofthetankcontainingtheacid;itshouldnotbepossible
toremovethetubebysimplypullingonit.
Thetankholdingtheacidshouldbestableandlocatedoutofthereachofchildren.
