1. The softenerrequiresan inletwaterpressurebetween 140kPa(20psi)and 690kPa
(100psi).
2.The softenershouldserviceall waterlinesinthe houseexcept the toilet and outside taps.
The softenershouldbe positioned on alevelflatsurfaceclosetoadrainoranyother
properlytrapped wasteoutlet.
The brass adaptorssupplied aresuitablefor20mm (3/4")femalefittingsand the softener

3.When facing the front of the controlthe inlet istothe right and the outlet istothe left.
4.The systempressuremust be between 140 kPaand 690 kPapsi.
5.If the systempressureisgreaterthan 690kPapsia pressurereducingvalve mustbe
installed.
6.The unit must be installed inaccordancewithlocalcodes.
7.Donot overtighten connections.
8.Drainline IDmust be at least 12mm.
9.Teflon tape shouldbe used when installing he drainfitting intothe controlvalve.
10.The drainline must be free of kinks.
11.Asafetyfloat withan aircheck isinstalled.
