2. Installation
Please observe the regulations concerning the installation of your filter system. Check that
you have allowed space for access to the unit for possible future maintenance. This
installation may require plumbing work and will require an electrical outlet to be fitted near the
system. Only attempt this if you have the necessary skills.
2.1 Pre-installation checks
The area needs to be level, frost free, have access to electricity and an open drain. Check the
incoming water quality is within any parameters specified for that media (see technical
information later in the manual). In addition to this check the incoming water pressure is
between 2 and 8 bar (preferably approx. 4 bar) and the water temperature is between 3ºC
and 45ºC.
2.2 Fitting the Distribution System
Fit the bottom distribution system into the vessel – the bottom screen should been pre glued
to the riser tube (fig A.1) (smaller systems). Alternatively if the system uses bottom laterals
these need to be assembled inside the vessel (fig A.2), Move the vessel in its final position as
it will be difficult to move once the media has been added.
Fig A.1 Fig A.2 Fig A.3
2.3 Adding the Media
Block the top of the riser tube to stop media getting down the tube.(see fig A.3). Add about
1/3 by volume of water to the vessel so when the media is poured in it doesn’t damage the
bottom distribution system. If you have been supplied gravel with your kit this should be
added first so it covers the bottom distribution system. Add the other media supplied but make
sure there is 30%. free space left above the media so when the system is backwashed the
media can expand into the space and the sediment and contaminants can be backwashed
away (there may be media left over). See section 5.4 for more information on the Medias.
Unblock the riser tube.

5
2.4 Fitting the Valve
Add a small amount of silicone grease to the valve outer and inner o-rings (fig A.4 & 5).
Fig A.4 Fig A.5
If a top screen is supplied this should be attached next. (Not always used)
Slide the valve onto the riser tube and gently push it down onto the vessel treads. Screw the
valve on until you start to squeeze the main O ring and then finally give the valve a final
tighten by tapping the rear side of the valve with the palm of your hand (fig A.6)
Fig A.6
2.5 DLFC (drain line flow control)
This is possibly one of the most important components to check has been installed; this will
control the backwash flow rate and ensure the system will continue to function correctly. The
DLFC will either be fitted inside the drain line elbow, the 1” adaptor or in an external housing.
The larger external DLFC may have more than one flow controls fitted to gain the required
flow rate. See below pictures of the drain line housings.

2.6 Electrical connection
To connect the power cable you need to firstly remove the
cover then remove the drive bracket assembly by pressing
up on the drive brackets release tabs and pulling towards
you, the drive bracket including software can now be lifted
away to reveal the back plate (fig A.7). Fig A.7
When the drive plate has been removed, locate the knockout on the
backplate. You can use a punch or a Phillips screwdriver to do this.
(fig A.8)
You can now re install the drive bracket into its original position.
Please make sure that this has been replaced correctly as this
can cause problems at a later date. Fig A.8
Fig A.9 Fig A.10 Fig A.11
Remove the tabs at the bottom of the strain relief on the back side of the back plate (fig A.9).
You can now connect the power cable to the valve and any additional cables that may be
needed for no hard water bypass (CI only) or micro switch cables through the knockout. After
connecting the cables you can weave the wires through the strain relief (fig A.10) and fit the
cover supplied (fig A.11)

3. Commissioning the Filter
3.1 Introduction
With the system fully plumbed (see below) and the valve programmed commissioning can
start.
3.2 Backwash
When the system is fully functional the backwash will happen at the pre-set time (see
programming the valve section). However, running a manual backwash during commissioning
is the best way of removing air from the system, bedding in the media and flushing the
system.
Make sure the water inlet and outlet are closed. Press and hold the regeneration button for 5
seconds. The motor will turn and the piston will move to the backwash position. Slowly half
open the water inlet to the system, and then slowly open the outlet to allow the air to be
purged from the system. Once this has been done you can fully open the inlet and outlet and
allow the system to continue through the backwash cycle, this will allow you to check for leaks
and also purge any remaining air from the system. After a backwash the system will move
through a short rinse cycle and then stop in the service position.
For new systems or after a media change it maybe necessary to run two backwashes to fully
wash the media (check the water at the end of the backwash is running clear).
For TURBIDEX please see below.
Initial backwash instructions for Turbidex filtration media.
Due to the naturally occurring dust and fine particles found in zeolites it is important to
thoroughly clean the new bed to prevent plugging of the distributor slots. Zeolite fines are
crystalline in structure and may get wedged in the slots, becoming very difficult to remove.
Important: Throughout this procedure, do not place the unit into rinse or service until you are
sure the bed has been cleaned of fines.
Always start the unit in backwash and slowly open the by-pass valve until the unit is full of
water (as evidenced by a gradual flow to drain). Shut off the by-pass and allow the unit to

saturate for a minimum of one half hour for filters below 16”, one hour for 18” to 30”, 2 hours
for 36” to 48” and a minimum of 3 hours for larger vessels.
After the media has been fully saturated, open the by-pass until the full backwash flow is
reached. Inspect the water going to drain for evidence of the water being milky in colour.
Once the water going to drain begins to run clear, close the by-pass and allow the unit to
settle for 5 minutes.
Open the by-pass again and inspect the water going to drain, again you will notice a milky
colour in the water.
Repeat this procedure until there is no longer any colour in the water going to drain.
At this point you may rinse the filter for 10 to 30 minutes depending on the size and then
place the valve into the service position.
Note
Check the service and backwash flow rates (see technical information). If the service
flow rates are exceeded or the backwash flow rate is not correct then the filter may not
work correctly.
If during a backwash cycle you need to skip through the cycle this can be done in the
following way. To skip to the next stage press the REGEN button.
3.3 Service
Water flows into the valve at the top, down through the media and then up through the ‘riser’
tube in the middle of the vessel. As the water travels through the media the contaminants are
removed. The timer options are set to automatically self clean (backwash) and wash away any
of the accumulated contaminants.
4.Routine Maintenance
The filter system is designed to run with the minimum of maintenance and does not normally
require much adjustment.
Monthly
Check there is no sign of damage or leaks, check drain lines and power cables are still
in good condition and not kinked.
Yearly
We recommend that a competent service engineer checks the system annually. The
inlet and outlet pipes need to be rinsed, the drain line checked for degradation, and the
system flushed through. The media should be checked, if pH it probably needs to be
topped up.
The quality of the treated water needs to be checked regularly. How regularly depends on
what the water is being used for eg drinking water or irrigation etc. If the water is being used
for drinking water then it needs to be checked more regularly and the relevant Private Water
regulations covers the sampling and testing routines for England this is “The Private Water
Supplies Regulations 2009” No. 3101. However it is sensible to at least partially test the
treated water every 3 months or so and certainly every 6 months to look for compliance. A
competent water treatment company can help with this.

5. Technical Information
Note: Check the service and backwash flow rates (see technical information). If the
service flow rates are exceeded or the backwash flow rate is not correct then the filter
may not work correctly.

Birm can be used for iron and manganese removal by oxidation (up to 15ppm). It requires a
pH of 7 or more for iron removal and pH 8 for manganese removal (it uses dissolved oxygen
in the water to oxidise the metal). As it acts a catalyst it is not consumed so Birm doesn’t
require regenerating or topping up (does require backwashing). Birm also has the advantage
of acting as a filter removing relatively high levels of turbidity. It is advised not to use Birm in
combination with chlorination and the water should be free of oil, polyphosphates and
hydrogen sulphide. Alkalinity should be greater than twice the sulphate and chloride level and
the organic loading should be below 5ppm. If the pH of the water is too low pH correction
maybe required by adding a pH correction media such as Juraperle or Corrosex. Birm
requires a dissolved oxygen of at least 15% of the iron and manganese content to work..

requires a pH of 7 or more for iron removal and pH 8 for manganese removal plus a dissolved
oxygen level of at least 15% of the iron and manganese content. It needs a high backwash
flow rate to remove the oxidised iron and manganese but can cope with high service flow
rates. Filox can also cope with chlorinated water. NSF certified, Freeboard 30% to 50%

Water with a pH below 7 is acidic and can damage copper pipe-work and heating systems.
Raising the pH will neutralise the water stopping the corrosivity, removing the metallic taste.
The pH is raised by passing the water through a vessel containing slowly dissolving calcium
and magnesium salts. These salts slowly dissolve into the water 're-mineralising’ the water
and naturally raising the pH. Make sure that there is 30% freeboard.
Juraperle: a granular media made up of 99.4% calcium carbonate. It has a superior
performance to limestone due to its micro-crystalline structure and dissolves very
slowly. Juraperle is consumed and from time to time new media should be added.

16
Corrosex: a highly magnesium oxide salt and is used most effectively where the pH
correction is substantial or the flow rate is high. In reality for a pH of less than 6 a 25%
Corrosex, 75% Juraperle mix is ideal.

Sediment filters are needed when the water supply is cloudy or turbid. The particles in the
water will block plumbing systems, leave unsightly staining, may contain toxic chemicals or
bacteria. The easiest way to remove the particles is by passing the water through a media
where the particles get stuck and allowing clear water to flow through. The particles can be
periodically ‘backwashed’ away to drain.
Sand: The grade of sand is tightly controlled so only highest quality; triple washed 0.5 to
1mm size water treatment grade sand is used. Particles above 40 micron are typically
trapped.
Filter Ag: Has a high surface area and complex flow path for a more efficient removal of
suspended matter. Filter Ag is also lighter in weight than sand which reduces backwash flow
rate. Particles down to 20 micron can be trapped. Filter Ag should be soaked for 24 hours
before use.

Severn Trent worked to develop an arsenic removal media formulated to give a high arsenic
removal capacity. The media is strong, reliable and easy to handle. Arsenic is trapped within
the media and held even when it is backwashed. Typical life time of the media depends on
arsenic levels and the amount of water used. A 1054 system with 1 bag of media (15 Kg) can
typically be expected to treat 1500m3 of water at 50ug/l Arsenic .For a family of 4 the media
should last about 6 years.
Pre-treatment may be necessary as the raw water must contain: Iron <200ug/l, Manganese:
<50ug/l, Silica (SiO2) <40mg/l, Phosphate: <200ug/l, pH: 6.5 to 8.5, suspended
solids:<10mg/l.
Backwash frequency 14-28 days.

Activated carbon (GAC) works by absorbing soluble pollutants onto its surface and holding
them. Eventually all the pores are filled and the carbon needs to be replaced. GAC is used to
reduce chlorine, natural colours and odours from water.
