Thank you for purchasing this Wrekin Water Softener. We are sure this will provide you with many
years of trouble free service. This guide is designed to help you plan, install and commission your
softener correctly so that you get the best out of the machines capability
PLANNING YOUR INSTALLATION
The installation schematic found later in this guide covers all the aspects to assist you with the
correct installation of the softener and covers the main points you need to consider during the
planning stage of your installation (FIG 1)
Check that you have only one rising main and that you have allowed space to access the unit for
possible future maintenance and salt replenishment.
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 skills
POSITIONING THE SOFTENER
Where possible the softener should be placed close to the rising main. Allowances should be
made to take hard water take off points for untreated drinking water and/or outside taps if required.
Ensure that the drain and overflows will not freeze or reach temperatures higher than 40°C. If the
softener is to be placed inside a cupboard ensure that the base has adequate support. If you are
fitting in a loft space, then the softener should be placed inside a secondary tank/container with its
own overflow fitted at least 3/4in in size. This overflow on the tank must be positioned lower than
the overflow located on the softener. A tank size capable of holding 100 litres would be preferable
if space allows. If installation is to be outside, then this must be contained in a well, insulated
cabinet containing at least 2”of High Grade insulation on all sides and any other steps taken to
avoid freezing
SINGLE CHECK VALVE.
A suitable check valve should be fitted on the supply to the softener. This can be purchased
separately or will be included in the optional fixing kit supplied with the machine.
WATER PRESSURE TEST
It is important to test the water pressure. 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 fitting a pressure limiter should your daytime pressure exceed 5bar (70psi). A 5 Bar
PRV can be purchased separately. The minimum working pressure is 1.4bar (20psi). Please note
that partially closing the stop cock will not reduce maximum pressure, it will just reduce flow.
WASTE PIPE CONNECTION
The waste, or Drain pipe should be run to an up stand with a 20mm air gap or to an outside drain
or gully. Softened water waste will have no adverse effect on septic tanks. Should you need to
extend the drain hose this can be done by connecting to 15mm copper tube to a maximum run of
8mtrs with a daytime pressure of 40psi and can be run uphill to a maximum of 1m per 40psi of
daytime pressure Ensure that the drain hose is not kinked or obstructed in any way as this will
lead to an overflow of the softener. A plumbing out kit, with its own Non-Return Valve that can be
attached to a 32mm or 40mm waste pipe to assist in the drain connection can be purchased
separately if required
Now you can commence the installations of the valves. Before starting, ensure that you have
turned off the water supply at the main stop cock

Fig 1 –Typical Installation Schematic
CONNECTING THE SOFTENER
Once the installation of the valves is complete, and with the inlet, outlet and bypass valves closed
the stop cock can be turned on. Then open the bypass valve and check for leaks in the plumbing
and correct as necessary.
You can now proceed with the connection of the softener to the valves, which is normally done
with flexible hoses as in FIG1. The direction of flow is embossed on top of the softeners tails so
you can identify which port is the flow in and which is flow out. Ensure that the hoses are attached
to the correct ports. The drain connection is normally the central port as in FIG1 above. Hoses
normally are supplied with a bent connector on one end, which is usually fitted to the rear of the
softener and a straight connector on the other. A sealing washer must be inserted into the
connectors to achieve a water tight seal when attaching the hose to the softener and the valves. A
washer is also supplied for the drain connector.
WASTE PIPE CONNECTION
Connect the waste pipe ensuring kink free. If fitting into a standpipe ensure that the hose is
fastened securely as the waste is vented at mains pressure to prevent the hose from coming out
during the cleaning process
OVERFLOW
The overflow connection is the white 1/2in hose spigot on the rear of the cabinet. The overflow
must run downhill through an outside wall with no kinks or restrictions. It is recommended that the
white hose is 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 back left
hand side of the control panel. Ensure the flying lead cannot get caught on the camshaft
or any moving parts on the Softener valve. The power lead is best fed down the right
hand side and placed under the clips that hold the existing wires. The front display panel
can be unclipped from the valve frame so that the power lead can be fed through the
frame and behind the control panel. Re-clip the control panel back into position. The
release clip for the control panel is at the back of the panel on the left hand side as you
face the softener.

The hardness figure is arrived at by using the test kit that comes with your softener. This setting is
important on the metered machines as this determines the capacity of soft water that can be
produced between regeneration cycles. In normal Service mode the display alternates between
the time of day and Flow Rate through the softener. If there is no flow, 0 will be showing. The flow
indication also has a running tap symbol that appears at the same time. Hardness is input as PPM

SET TIME
Press the set button. The time should be flashing and a small pointer indicator will display the programme
function you are setting. Using the up or down arrows set the time and confirm by pressing the set button
SET DAY OF THE WEEK
Press the set button to display the days of the week. Display will flash, using the up and down arrows bring
the indicator to the required day and press set to confirm
SET DAYS TO REGENERATE
A. Metered Models: This is a calendar override that forces a regeneration if you haven’t used enough
water in the set days to do an automatic regeneration. This enables the resin bed to be refreshed at
reasonable intervals. The override days should be set between 7-21 days. The default setting is at
14 and this can be left on this setting unless there are obvious reasons to change it:
a. Press SET and the display will flash and use the up/down arrows to the desired setting
b. Press SET to accept
B. Timed machines: This then applies on how many days you want to elapse on a timed model before
the machine regenerates. This setting can from 0.5 days to 21 days. The default setting is 3 days
a. Press SET and the display will flash and use the up/down arrows to the desired setting
b. Press SET to accept
TIME OF REGENERATION
Press the Set Button and display will flash. This defaults to 02:00 hrs (2am) and this is the time the
machine will perform the regeneration cycle. The regeneration requirement will be determined by the
hardness settings you input on a metered softener or by your planned days sequencing on the Timed
version. If you prefer the machine to clean at an alternative time of day, this can be set now by using the
up/down arrows. Otherwise, press SET to accept the default setting.

COMMISSIONING THE SOFTENER
Now the programming is complete it is time to turn on the water supply to the softener. There is no
hard and fast rule on this but we prefer to use the following sequence
1) Close the bypass valve
2) Partially open the inlet valve to the softener until the softener is pressurised. This gives you
chance to inspect for any leaks. Once pressurised, the Inlet valve can be fully opened
3) Once the softener is pressurised and all fittings and connections are water tight, we are
going to prime the softener ready for use by fast tracking the softener through a
regeneration cycle. Be sure that your drain connection is fitted correctly as water will be
vented out of the drain at various stages of this process. Before we do that, familiarise
yourself with the information that will be shown in the display panel.
When the softener is in the regeneration mode, the display will change from the clock and show
information as below
The Key Points are
The Triangular REGEN symbol shows in the display throughout when a regeneration cycle
is in progress
The Egg Timer Symbol shows when the CAM is rotating. Only advance the cycle when this
symbol disappears confirming the cam rotation has stopped
The stage of the regeneration cycle will be indicated by the letter C following by the
regeneration Sequence number.
To start the manual regeneration, press the REGEN button for 3 seconds and release
To advance to the next stage, press and hold the SET button and press the up arrow once
and release both. This must only be done when the EGG timer symbol is not visible in the
display
The time shown in the display is the time remaining of the regeneration cycle. As you fast
track through the cycle this figure will change.

20230701
Now we are ready to force a manual regeneration:
The Regeneration cycle comprises of a number of stages as below:
C1 Backwash (Prepares Resin bed by aerating the bed for brining)
C2 Brine and slow rinse (Draws brine from the Salt bin through the resin)
C4 System Pause (Re-pressurise the tank)
C5 Fast Rinse
C6 Backwash Cycle 2
C7 Fast Rinse
C8 Refill –Fill Salt tank with Water
Immediate Regeneration
1) Press the Regeneration button for 3 Secs. The cam will rotate and stop at C1. Leave at this
stage for about 1 minute. This will allow any discoloration in the resin to be washed to drain
2) Advance the programme, 1 sequence at a time by pressing and holding the SET button and
then pressing the UP arrow once then release both. The Cam will move, the indicator Egg
Timer symbol appears and when it disappears the C code will advance to the next stage
3) Repeat the above process until the C8 sequence is reached. Allow the C8 sequence to
finish fully. At this stage, water will begin to fill the salt bin. At this time any remaining air in
the cylinder will be expelled and the correct level of water will be put into the salt bin after
the sequence fully times out.
4) Following the completion of C8 –Refill, the display will return Service Mode and the display
will start alternating between Flow Rate and capacity remaining. Capacity is expressed in
cubic meters and this figure will reduce as water is consumed. Please note –Flow rate will
show “O” if no flow is being recorded and the flow rates are expressed in litres per min.
5) Turn on the Outlet valve fully and double check that the by-pass is fully closed. Your
softener is now producing softened water. Fill up the Salt Chamber to within a few inches
from the top of the bin with salt and your installation is complete
6) When completed, the clock returns to “in service” mode. The display will alternate between
capacity (expressed in m3) and Flow Rate and tap symbol. (Metered Versions Only). The
flow will show “0” when there is no soft water being drawn off. When water is flowing
through the machine, the flow rate will be displayed accordingly. If there is no flow
indication, check that the bypass valve is fully closed and the contact cable on the outflow
port is fully home and secure.
