4. INSTALLATION
Thedeviceshouldbeinstalledinthepoolplantroom,protectedfromtheweatherandthesun.

Important:Whenchoosingthelocationsofthecontrolpanelandthecell,andbeforestartingwork,
makesurethattheelectricalcablethatwillconnectthepanelandthecellislongenoughto
make the connection;
4.1.1 Mounting the cell
• InthecaseofthePROAandPROLS65and200models(equippedwithagassensor),thecell
mustbeinstalledverticallyandatahighpointsothatthegassensorlocatedonthecellpower
supplysidecanrunproperly.Ifitisnotpossibletoinstallthecellverticallyatahighpoint,aow-switch
kitmustbeinstalled.
• InthecaseofthePROLS300model,andothermodelsttedwiththeFlow-switchoption,thereareno
constraintsregardingtheorientationofthecell,onlythatoftheow-switch(see4.1.5).
• Respectthefollowingdirectionofow:watershouldenterthecellfromthetop,owpastthe
electrodesandexitfromthebottom.
4.1.2 Mounting the temperature sensor
• Mountthesensorhousingonaby-passloop(50or63mm)locatedbetweenthelterandtheheating
device(seethehydraulicinstallationdiagram).Thehousingmustbeorienteddownwardssothatthe
sensorsarealwaysinwaterandtheirreadingsarerepresentativeofthecurrentpoolwatervalues.The
housingmustbeinstalledonahorizontalsectionoftheby-passloop,orientedsothatthesidewith2
holespointsup(optionalpHandRedoxsensors),andthesidewithoneholefacesdown(temperature
sensor).Screwthetemperaturesensorsdirectlyintothedownwardfacing1.2‘‘tappedorice.
