1.2 MISSING OR DAMAGED GOODS
Immediately on receipt of the goods, it is advisable to check that all items
ordered have been received. If you have any doubt that goods have been
supplied as requested, please contact your supplier immediately. If any
items are missing or damaged, the carrier and your supplier must be notified
within 2 days of receipt if a claim is to be made.
2.0 TEMPORARY STORAGE
If installation is not to start immediately after delivery, the equipment should
be stored in a clean dry area, where it will not be damaged, or be subjected
to temperatures below freezing.
3.0 REGENERATION
3.1 The Regeneration Process
The regeneration process consists of six stages:-
1. Backwash - Water flows upwards through the resin bed, and out to a
drain. As it does so, it loosens the ion exchange beads, removes any resin
'fines' (i.e. small pieces of broken beads etc.) and cleans off any particles of
dirt or pipework corrosion products which may have accumulated during the
service cycle.
2/3. Brine/Slow Rinse - During the first part of this stage, the
concentrated salt -solution is drawn from the brine tank, blended with water to
reduce the concentration to the correct level, and passed down through the
resin. When the required quantity of brine has been drawn in, the water flows
alone to push the remaining brine through the resin at the correct rate, and
ensure that all of the resin sees the right amount of regenerant.

WS1”, 1.5” & 2” Series NRU
Installation Operation Maintenance Manual
Simplex Clack NRU rev 1 Page 4 of 27
4. Backwash (2nd) - This valve has the unique facility of performing a second
backwash allowing for optimum regeneration, efficiency and cleaning of the
resin bed. Water flows as in the first backwash cycle.
5. Fast Rinse - This follows the brine and slow rinse cycle, and entails rinsing
away the residual brine and Calcium and Magnesium salts from the resin and
re-packing the resin bed. This is carried out down flow with water flowing
through the resin in the direction of service.
6. Salt Tank Refill - Following the fast rinse, a quantity of water
sufficient to dissolve the correct amount of salt for the next
regeneration is returned to the salt tank. When this has finished, the unit
automatically returns to service.
3.2 METER CONTROL OF REGENERATION
On meter controlled valves a water meter is installed in the outlet from the
nru, to measure the volume of water which passes to service. The internal
turbine rotates with the flow of water and reports its rate of rotation through
Hall-effect circuitry to the printed circuit board. When the reading reaches
zero the valve will automatically regenerate that night at 2 am for delayed
regeneration nrus or immediately for immediate regeneration nrus.
3.3 TIME CLOCK CONTROL OF REGENERATION INITIATION
Time clock configuration valves initiate regeneration at a pre-set time after
a pre-set number of days. The frequency of regenerations are adjustable
on programming the timer (Regeneration control).
4.0 PRE-INSTALLATION CHECKS
4.1 MECHANICAL
4.1.1 Foundation/Drainage
The nru will not require any special foundations, provided that a firm, level
area which is capable of supporting the working weight is available. (See
Engineering Data, Section 11.2)
Unwanted water from the regeneration process must flow to drain, and so
an open drain or gully, capable of passing the necessary flow is required
(see Process and Operating Data, 11.1, for relevant flows). The total flow
of water to drain depends on site conditions, but will be approximately 6
times the resin volume. Preferably the drain should be level with or no higher
than 500mm above the nru valve.
A second drain is required for the brine tank overflow. This is a safety drain
which will only discharge water if there is a malfunction in the control
valve. Where possible this should be installed through an outside wall
like a cistern overflow, where it will give a visual indication of any failure.

WS1”, 1.5” & 2” Series NRU
Installation Operation Maintenance Manual
Simplex Clack NRU rev 1 Page 5 of 27
4.1.2 Operating Space
The space occupied by the nru can be found in the Engineering Data
(Section 11.2).
Access will be required to refill the salt tank, and to carry out
adjustments or maintenance on the equipment. It is therefore
recommended that a minimum of 500mm clearance be allowed in front of
the unit for this purpose.
4.1.3 Incoming Water
The raw water to be fed to the nru must comply with the following:-
1. Available at all times at a flow equal to or greater than
the required service flow
2. At a pressure between 1.7 and 8.0 bar
3. Temperature between 4 and 38oC
4. Suspended solids less than 1 ppm
5. Iron less than 0.2 ppm, Manganese less than 0.1 ppm,
Free Chlorine less than 1 ppm if temperature is less than
15oC, less than 0.3 ppm if temperature higher (up to 30oC)
4.1.4 Pipework
Pipework to be connected to the nru should not have an excessive
amount of nitrate and sulphate scale deposit. Piping that is heavily built up
with scale (or Iron deposits) should be replaced.
Make sure that the pipework can be connected to the nru in such a way as
to impose no stresses on the control valve, and that it is properly aligned
and supported.
A system for the complete by-passing and isolation of the nru should be
installed.
4.1.5 Water Supply Company Requirements
It is essential that if the equipment is to be connected directly to a mains
water supply, the local bylaws must be adhered to. These cover both
plumbing and the prevention of backflow into the mains. If there is any
doubt, the local water inspector should be consulted, but in general, the
installation of a 'Double check valve assembly' conforming to BS6282 part 2
will be required in the feed pipework to the nru.
If the pressure available from the mains is not adequate it will be
necessary to install a booster pump arrangement. Such a system would
be covered by additional bylaws, and the water storage tank needed must
comply with these.

WS1”, 1.5” & 2” Series NRU
Installation Operation Maintenance Manual
Simplex Clack NRU rev 1 Page 6 of 27
4.2 ELECTRICAL
A continuous supply of 240v, 5 VA is required. The nru itself is 12 volt but a
plug in 240v/12v transformer is supplied and should be connected to an
uninterrupted mains supply, which is separately 1 Amp fused, and does
not have any additional switch.
5.0 ASSEMBLY/INSTALLATION
5.1 MECHANICAL
Check all the items against the parts list and shipping documents, and
ensure you have them all before starting work. In addition to the nru
you will require installation materials and basic tools, (i.e., spanners,
screwdrivers etc., and PTFE tape)
5.1.1 Pipework
Pipework should be assembled incorporating the features shown in the
Installation Diagram, Section 14.1. It is essential that inlet and outlet
isolating valves and a by-pass valve are provided, and that the water main
is protected by a double check valve where appropriate (see Local Water
Bye-laws).
Pipework can be constructed from any normally acceptable material
(Copper, Galvanised, Plastic), provided it is properly supported and
aligned. Ensure that the pipe is sufficiently large to accommodate the flow
of water required, making due allowance for the pressure drop between
the nru and the point of discharge of soft water.
NOTE: IF BRAZED OR SOLDERED FITTINGS ARE TO BE USED, THE
PIPE WORK MUST BE DISCONNECTED FROM THE VALVE DURING
HEATING AND COOLING. EXCESS HEAT CAN CAUSE PERMANENT
DAMAGE TOSOME OF THE VALVE COMPONENTS.
5.1.2 Assembly
If possible place the pressure vessel on its final location before filling. Check
that the distributor tube, with its yellow top cover, is in place and using a
funnel slowly pour in the resin taking care not to spill any on the floor. Ensure
that the distributor tube remains central in the vessel during filling. After
emptying all the bags, the vessel should be almost 75-80% full. This is to
allow for the rising of the resin bed during backwash. Once the vessel is
filled, immediately sweep up any spilled resin.
Remove cover from distributor tube and brush any beads of resin out of
the threads in the neck of the vessel.

WS1”, 1.5” & 2” Series NRU
Installation Operation Maintenance Manual
Simplex Clack NRU rev 1 Page 7 of 27
Unpack valve and skip down over the distributor tube. Screw the valve in to
the resin vessel, taking care not to cross the threads. Excessive force
should not be needed as the valve is running in to the vessel. Finally
tighten to approximately 20 ft/lbs torque. Adjust position of vessel to line
up piepwork connections, not the position of the valve on the vessel.
Position the brine tank and connect brine line to the bulkhead
connector above the overflow (3/8”). Ensure that a brass insert is placed
inside the brine line before connecting.
Connect inlet and outlet pipework to the valve (1” BSP 90 deg or straight
male threaded elbows at rear of valve) using flexibles where possible or rigid
high pressure pipe and socket unions. Some felxible pipework is
advisable to prevent stress on the vessel as it cycles during service, since
it will expand and contract longitudinally.
Connect drain line to the drain outlet (3/4” male threaded elbow on top of
valve). Ensure that there is an air break in the drain line at the same height as
the valves to prevent negative pressure on the vessel.
Connect brine line to the brine connection on the valve. Again ensure that a
brass insert is placed inside the brine line before connecting.
Connect power supply to valve and commission.
6.0 PROGRAMMING
6.1 INTRODUCTION
It is recommended that the commissioning of the plant is undertaken by a
trained service engineer, who will be able to put the plant into service
quickly, and most efficiently. However, if the services of an experienced
engineer are not available, following the steps outlined below will result in
the system being properly commissioned.
6.2 CONTROLLER SETTING - Site programming mode
All controller settings will require the valve to have the mains supply
switched on. The valve must not be regenerating when controller
settings are adjusted.

7.0 COMMISIONING
The objective of commisioning is to fill the nru and brine tank with water,
check for leaks and prepare it for service. The simplest way to
commission the unit is to initiate a regeneration. This will eliminate the
air from the system and flush the resin prior to use.
Manually add water to the brine tank until it is filled approximately 6”
(100mm) from the bottom of the tank.
Before opening the inlet water supply, ensure that the outlet is shut and
switch on the power supply and press the “REGEN” button on the
valve. “Regen today” will appear at the bottom left of the timer, by
continuing to press the “REGEN” button the motor will power up and
move the valve into the backwash position. Slowly open the inlet valve.
At first, air will be expelled from the drain line, followed by water once
the vessel is full. The first quantity of water will have a tan colouration
which is perfectly normal. Allow water to run to drain until the water is
clear.
Next, press the “Regen” button and the motor will move the valve into
the brine and slow rinse position. Ensure that the water level in the
brine tank drops as water is drawn in. During brine and slow rinse
water will slowly run to drain.
Press the “Regen” button 3 more times (after pressing the button once,
wait for the motor to stop before pressing it again) until the valve
reaches the refill stage. Ensure that water is now refilling the brine
tank. Leave to fill for full duration of the cycle and add salt to the brine
tank. The level the water will reach depends on the type of salt used
and the resin volume of the nru
At the end of the refill cycle the motor will automatically move the valve
back into the service position. The nru is now commissioned. Open
the outlet from the nru to run water to service.
Add salt to the brine tank. If tablet salt is used (recommended) then
the cabinet can be filled to the top. If granular salt is used then the
cabinet must only be 3/4 full.

8.0 ROUTINE MONITORING
The following recommendations are made to help the user of the
nru confirm that it is performing as required, and to give early
warning of possible problems. The operation of the nru is
completely automatic, and should not require adjustment.
Weekly
Check the treated water nitrate and sulphate with a nitrate
and sulphate test kit. Inspect the level of salt in the salt tank
and refill if necessary.
Monthly
Check raw water nitrate and sulphate, and record. Compare with
original nitrate and sulphate and adjust volume capacity setting if
required (see Section 12.0).
Annually
Inspect and clean/replace as necessary the brine injector, brine screen
and the internal seal spacer set. This should be performed by a
competent engineer familiar with the WS1 valve.

SIMPWS1 REV2 06/08/10 PAGE 14 OF27
9.0 FAULT FINDING AND RECTIFICATION
Modern Nitrate Removal Unit are extremely reliable and unlikely to give
any problems if they are installed and operated correctly.
9.1 NO FLOW TO SERVICE
Check mains pressure is above 1.7 bar.
Check inlet and outlet isolating valves are open.
Check service outlet valve is open.
Check pressure drop across resin. If excessive, resin may be fouled,
or internals blocked. Initiate a regeneration. If this does not free up
the resin the nru will need to be inspected and serviced by a
competent engineer.
9.2 POOR TREATED WATER QUALITY
Check manual by-pass closed.
Check salt level in salt tank. Refill if necessary.
Trickle flow through conventional ball valve in storage tank. Replace
with Torbeck or Fluidmaster servo valve.
Check raw water pressure above minimum. If flow is less than
minimum, channelling of water can occur in resin. which results in
inadequate treatment.
Check injector strainer and injector not blocked (see Appendix for
drawings). Clean if necessary.
Check brine pick-up screen not blocked. Clean if necessary.
Check brine line not split. Replace if necessary.
Check raw water nitrate and sulphate, and then check if capacity setting
is correct for this nitrate and sulphate (see Section 12.0)

WS1”, 1.5” & 2” Series nru
Installation Operation Maintenance Manual
SIMPWS1 REV2 06/08/10 PAGE 15 OF27
9.3 NO REGENERATION
Check electrical supply, fuses etc. satisfactory.
Check control head motor runs by initiating a manual regeneration
(Press “REGEN” button for 5s and then again for a further 5s), listening
for drive motor ‘whirring' as it advances between cycles. Replace if
necessary.
Check internal meter running freely (if fitted) indicated by small black
dot in center of display flashing.
9.4 UNSATISFACTORY CAPACITY BETWEEN
REGENERATIONS
Check condition of resin. It may have become fouled, inhibiting the
regeneration process. If fouled, it should be cleaned or replaced.
Check incoming water for presence of Chlorine. If high, the resin may
have been degraded.
Check raw water pressure. Too high pressure may mean the brine
draw stage of regeneration is not effective
