1. 1 Positioning the water softener It is very important to establish the water pressure before installing the water softener If the water pressure is low then the water softener may not operate effectively If it is too high then components inside the unit may be damaged Water pressure should be tested with a gauge at the kitchen tap or outside tap It should be noted that water pressure can increase at periods of low water usage e g overnight If therefore the daytime pressure exceeds 5 BAR or if you are unsure about pressure then a pressure limiting valve should be fitted Where the pressure is less than 1 7 BAR a booster pump may be required 2 Inlet and outlet connections With the bypass valve open and the inlet outlet valves closed the unit can be connected to the plumbing system Arrows on the inlet and outlet piping from the valve will confirm the direction of flow Connections can be made in one of three ways where high flow rates are not required static head systems these connections can be made using the standard flexible hoses supplied with your softener ensure the hoses are not kinked as this may restrict flow For systems requiring higher flow rates those fitted with combination boilers or unvented pressurised systems the connections should be made using specialist high flow hoses supplied with a HI FLO softener or conventional copper tube and fittings 3 Drain connection Push the flexible drain hose onto th2.
