f
Pipework (J in installation layout) sized min. DN50. Use only the flexible DN20 hoses included in
the delivery. Ensure a correct sealing and setting of all pipes before first commissioning.
f
To comply with good plumbing practice the external waste-water-drainage must have a minimum
space of air: 20 mm (according to guideline EN 14743).
f
Drainage from the overflow of the brine tank, Connections between the channel and two flexible
hoses (according to standard EN 3131).

To increase the lifetime of your softener ensure it is kept in a clean, dry place with an ambient
temperature between 5 and 40 °C. Incorrect temperature may result in damage to resin or compo-
nents.
3.6 Installing your softener
1. Positioning the water softener:
It is very important to establish the water pressure before installing the water softener. If the water pres-
sure 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 5.0 bar UK, 8.0 bar EU or if you are unsure about pressure, then a pressure reducing
valve should be fitted.
Where the pressure is less than 1.7 bar UK, 1.0 bar EU 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 plum-
bing system. Arrows on the inlet and outlet piping from the valve will confirm the direction of flow.
Connections can be made with either conventional copper tube and fittings or the high flow flexible
hoses supplied, ensure hoses are not kinked as this may restrict flow.
3. Drain connection:
Push the flexible drain hose onto the barbed connector (Drain; see chapter 3.4 Installation Layout) and
secure with the clip provided. Run the drain hose to a stand pipe or to a drain. The air gap needs to
be at least 20 mm. Softened water will have no adverse effect on a septic tank. You can extend the
drain up to 9m if you have sufficient pressure (greater than 3 bar). The drain hose must not be kinked
or restricted in any way as this will cause an overflow from the brine cabinet.
4. Overflow connections:
The hose barb overflow pipe (not supplied with the softener) should be connected to the push fit elbow
at the rear of the cabinet. Run the pipe downhill to the drainage. Take care that the overflow does not
discharge where damage could occur. If the water softener is fitted in a cellar or basement, the over-
flow can be run to a storage tank. Do not elevate the overflow hose.
