Page 5: General Notes
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual GENERAL NOTES These instructions cover the 9000/9100/9500 Range of Duplex Water Softeners, which includes models ranging in size from 20-120 litres resin volume fitter with ¾” – 1.1/2” Mechanical Meter/Timer or SXT Electronic Meter/Timer.
Page 6: The Softening Process
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual THE SOFTENING PROCESS Hardness in water is caused by the presence of dissolved salts of Calcium and Magnesium. In order to overcome the problems associated with the use of hard water, these salts must be removed. This process is called 'Softening'.
Page 7: The Regeneration Process
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual THE REGENERATION PROCESS The regeneration process consists of four stages:- 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.
Page 8: Duplex Operation
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual DUPLEX OPERATION A 'Duplex' system is a means of operation to achieve a constant flow of soft water to service, without the need for extensive treated water storage. The system is essentially two vessels, which are connected to common inlet and outlet pipework, and which are in service alternately.
Page 9: Unpacking And Parts Identification
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual UNPACKING AND PARTS IDENTIFICATION BASIC PACKAGES The Nitrate Removal will be delivered in a number of packages which include a pair of glassfibre reinforced pressure vessels, a control valve, slave valve adapter, interconnecting hoses, a brine tank, an even number of 25 litre bags of resin with possibly two additional part bags, and a funnel to fill the vessels.
Page 10: Description Of Plant Components
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual DESCRIPTION OF PLANT COMPONENTS NITRATE REMOVAL VESSEL AND INTERNALS The pressure vessel which contains the ion exchange resin is made from a fibreglass/epoxy resin outer layer surrounding an inner, seamless shell made from Polyethylene, Polypropylene or ABS.
Page 11: Brine System
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual BRINE SYSTEM The brine system consists of a moulded polyethylene tank into which the brine well and brine pick up are assembled. The tank forms the salt storage container. The brine pick-up tube within the brine well is connected to the pipe from the control valve which sucks the brine from the tank.
Page 12: Pre-Installation Checks
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual PRE-INSTALLATION MECHANICAL 6.1.1 Foundation/Drainage The Nitrate Removal 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 12.2) 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, 12.1, for relevant flows).
Page 13: Pipework
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual 6.1.4 Pipework Pipework to be connected to the Nitrate Removal should not have an excessive amount of hardness 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 Nitrate Removal in such a way as to impose no stresses on the control valve, and that it is properly aligned and supported.
Page 14: Assembly/Installation
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual ASSEMBLY/INSTALLATION 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 Nitrate Removal you will require installation materials and basic tools, (i.e., spanners, screwdrivers etc., and PTFE tape) 7.1.1 Assembling Vessel, Riser Tube and Internals The larger units are shipped as pre-assembled components to reduce the...
Page 15: Assembling The Control Valve
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual 7.1.4 Assembling the Control Valve Carefully remove the control valve and the slave tank adapter from their packing, and check that all parts are present. On the 9000 and 9100 valves, snap in the bayonet fit distributors to the control valve and slave tank adapter.

NOTE: IF BRAZED OR SOLDERED FITTINGS ARE TO BE USED, THE PIPEWORK MUST BE DISCONNECTED FROM THE VALVE DURING HEATING AND COOLING.
Page 17: Electrical
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual ELECTRICAL Electrical installation is very straightforward, but should still be carried out by a competent electrician, and must conform to the appropriate standards of safety. 7.2.1 Mains Supply The mains supply should be through a separate, switched supply, fused and earthed in accordance with Institute of Electrical Engineers Regulations.
Page 18: Commissioning
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual COMMISSIONING 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.
Page 19: Brine System
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual Press the extra cycle button to set the regeneration override. The default is 3 days for duplex softeners. This may be changed to a different interval by pressing the up and down arrows. Press the extra cycle button to exit the Site Programming mode.

9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual PRE-SERVICE FLUSH AND REGENERATION – MECHANICAL TIMERS Set the manual isolating valves so that water will by-pass the Nitrate Removal. Turn on the main water supply. Open a soft water tap close by and let the water run for a few minutes to flush out any debris or foreign matter from the pipework system.

This has now commissioned both vessels and the system is ready for service. 'Close' the timer so that the support leg snaps into the backplate. Adjust the capacity of the Nitrate Removal if necessary using the reference sheet attached.

Page 23: Operation
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual OPERATION NORMAL OPERATION Operation is completely automatic, with regeneration being initiated whenever required by the meter controller. REFILLING WITH SALT Since salt is used in the regeneration process, the level of salt in the brine tank will fall after each regeneration.
Page 24: Temporary Shut-Down
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual TEMPORARY SHUT-DOWN If the Nitrate Removal needs to be taken out of service for some time for any other reason, it is recommended that one or two simple procedures be undertaken to ensure the return to operation is as smooth as possible. The unit should be left with both columns fully regenerated regenerated.
Page 25: Routine Monitoring
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual ROUTINE MONITORING The following recommendations are made to help the user of the Nitrate Removal confirm that it is performing as required, and to give early warning of possible problems. The operation of the Nitrate Removal is completely automatic, and should not require adjustment (except as above).
Page 26: Fault Finding And Rectification
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual 10.0 FAULT FINDING AND RECTIFICATION Modern water softeners are extremely reliable and unlikely to give any problems if they are installed and operated correctly. 10.1 NO FLOW TO SERVICE Check mains pressure is above 1.7 bar. Check inlet and outlet isolating valves are open.
Page 27: No Regeneration
9000/9100/9500 Duplex Watersoftener Installation Operation Maintenance Manual 10.3 NO REGENERATION Check electrical supply, fuses etc. satisfactory. Check control head motor runs, by initiating a manual regeneration. Replace if necessary. 10.4 UNSATISFACTORY CAPACITY BETWEEN REGENERATIONS See Section 10.2. Check condition of resin. Resin may have become fouled, inhibiting the regeneration process.
