Thank you for purchasing this Softener. We are sure that it will provide you with
trouble free service for many years to come. Please use the following p ages to assist you
in the installation and set up of your new Softener.
Planning Your Installation .
Please observe the regulations concerning the installation of your water softener. For
guidance check out the water regulations advisory service web site ( www.wras.co.uk) Check
that you only have one rising main, that you have allowed space for access to the unit for
possible future maintenance and salt replenishment. Check the water pressure; locate the
rising main (stop cock) a drain facility and a power s upply.
Unless you are replacing an existing water softener, this installation will require you to carry
out plumbing work and may require an electrical outlet to be fitted near the softener. You
should only attempt this if you have the necessary ski l ls.
P ositioning the Softener .
Where possible the softener should be placed close to the rising main. Take care to allow hard
water take off points for a drinking water facility and /or an outside tap. The distance between
the drain and the Softener should be as short as possible . Ensure that both the drain and
overflow will not freeze or reach a temperature above 40°C . If putting the Softener within a
cupboard ensure that the base is adequately supported. If the Softener is being installed within
your loft etc i t is recommended to house the Softener within a tank capable of storing at least
100 Litres with an overflow fitted. The overflow on the tank should be below the Softener
overflow and be a minimum of ¾” in size.
A single Check Valve .
A suitable ch eck val ve should be fitted. This will usually be in the installation kit that can be
ordered separately.
Check List .
Before you start the installation make sure that you
have all the necessary fittings. The purchase of one
of our standard installation kits will normally ensure
that you have everything that you need for a typical
installation
Water Pressure Test .
It is important that a pressure test is carried out. High
and low water pressure can result in either damage to
or failure of the Softener. Although the Softener is
tested to a pressure of 8 bar (120psi) , we recommend
the fitting of a pressure limiter should your pressure
exceed 5 bar (70 psi) . The minimum working
pressure is 1.4 bar (20 psi)
Before starting the installation of the valves ensure that the s top cock is in the closed
position.

Connecting the Softener .
Once you have completed the installation of the valves set the valves as follows:
Softener Inlet and Outlet valve CLOSED
Bypass valve OPEN
You can now safely return the stop cock to the op en position . Using the hoses provided (if
installation kit ordered) connect the straight end of the h ose having first inserted the washer
provided to the softener inlet and outlet valves. Connect the angled end to the Softener. The
Softener inlets and outl ets should be indicated either with the words inlet or outlet or with an
embossed directional arrow o n the Softener tails. Normally the Softener tails are in a
configuration of three with the centre normally being the waste outlet.
Waste Pipe Installation .
Connect the waste pipe to the waste outlet on the Softener and run the hose to either an up
stand or outside drain, a minimum air gap of 20mm must exist at the end of the drain line.
Softened water will have no adverse effect on a septic tank. Should yo u need to extend the
drain hose this can be done by connecting to a 15mm copper tube for a maximum run of 8
meters with a minimum daytime pressure of 40 psi. Ensure that the drain hose is not kinked
or obstructed in any way as this will lead to an overflow of the softener. The drain pipe can
run uphill to a maximum of 1 Meter with a minimum water pressure of 40 psi.

Overflow Connection .
The overflow connection is the white ½” hose spigot on the rear or side of the cabinet. A clip
is not required for this connection. The overflow must be run downhill through an outside
wall without kinks or restrictions. It is recommended the overflow hose be visible when it
exits the outside wall.
Electrical Connection .
Connect the transformer provided to a continuous electrical supply with the power off. Plug
the flying lead from the transformer into the electrical connection on the controller (see
programming instructions). Ensure the flying lead cannot get caught on the camshaft or any
moving parts on the Softene r valve.
Preparing the Softener to go into service .
Now that all the connections have been completed put approximately 5 litres of water into the
brine tank. You may also at this point put a quantity of salt into the tank. Do not allow the salt
level in the brine tank to exceed the height of the overflow. The amount of salt used will
depend on the type and model of Softener you have, you should never let the brine tank
become completely empty of salt and it is advisable to check the salt levels on a regul ar basis
until a usage pattern has been established.
Putting the Softener into service .
You should now complete any programming instructions that may apply to your particular
Softener . During the commissioning process and initial regeneration you can con firm that the
unit has no leaks from the installed valves and that w aste water runs free. This regeneration
will also assist in cleaning any potential air locks that may be present within the system.
The regeneration will also reset any internal meter or timer devises that dictate the frequency
of the regeneration cycle.
