IMPORTANT ANNOUNCEMENT Supply of Spares - Payment by Credit/Debit Card
Siemens Water Technologies are pleased to announce that we are now able to accept payment for spare parts by major credit/debit cards. We appreciate that some of our Customers periodically require quantities of spare parts, possibly to repair plant breakdowns. Standard procedures, whereby an official order has to be issued before parts can be supplied, often hinders this process, leaving the operations/maintenance personnel frustrated and without vital spares to complete the job. If you, or your staff, have a valid credit/debit card, that is all you need. We will not require an official order to cover credit/debit card transactions. To order freephone 0800 7834628. Our staff will take all the details and advise you on price and availability of your parts requirements. Your order will be despatched the same day wherever possible (depending on the time the order is placed). If ordered late in the day, it will be despatched the next working day. An invoice will be sent to your designated invoice address with a copy of the credit payment slip for your records. We are sure that this “Fast Track” facility will be welcomed by your “sharp end” personnel who keep plant operational. R. Russ General Manager Sales & Marketing

4.3 Installation.
Only those persons suitably qualified/trained should undertake the installation of an Ezetrol®plus. Only those persons qualified to carry out electrical installation works should undertake the installation of electrical wiring of an Ezetrol®plus.
4.3.1 transport
During transport the Ezetrol®plus must be handled carefully and should not be exposed to wet weather or moisture.
4.3.2 unpacking
The equipment should be unpacked in a clean, dry area, preferably in the place in which the unit will be installed. All parts should be checked against the enclosed packing note before the packing materials are discarded.
��WT.050.425.00�.GE.IM.0�09
Ezetrol®plus analysEr/controllEr
Upon receipt, immediately check if package is free from damage and that the contents are complete. Report immediately any damage. Handle the sensors carefully when unpacking, as they can be broken if dropped on a hard surface.
notE: Each sensor is shipped with its tip immersed in a small cap of fluid, to prevent it from drying out. Leave the cap in place on the tip until you are ready to install the sensor into a sample cell with a fully established water flow.
4.3.3 location
There are a number of factors that should be considered as you select a location for the controller. These include, but are not limited to:
• A sound mounting surface to adequately support the board assembly.
• A location that is accessible, free from chemical fumes, excessive heat and dampness should be chosen as they can seriously damage the controller. Damage due to chemical fumes, including hydrochloric acid fumes, will invalidate the warranty.
• The controller should be easily accessible for taking display readings or making operating adjustments. Lighting should be adequate and clearance must be provided for service. Do not mount in direct sunlight.
• High voltage transformers and other energy-emitting electrical devices can affect the delicate sensing circuits of the controller. Locate the board assembly as far away as practical from sources of interference and be sure that it is electrically grounded as specified in the wiring diagrams.
• The Ezetrol®plus is designed to be permanently powered. The main power into the unit should NOT be interlocked with main circulation pumps. The controller has a secondary input (external stop), which is used to isolate the dosing pump outputs. This input is volt-free and must not be powered (or the controller will be damaged, invalidating the warranty).
• The main power feed should be provided from a ‘clean’ 10-amp switched and fused source.
• The position of the nearest drain should also be given consideration, as the standard Ezetrol®plus supply requires a drain that is open to atmosphere to which the sample water to runs. An optional return to filtration, post filer, pipework kit is available.
WT.050.425.00�.GE.IM.0�09�4
Ezetrol®plus analysEr/conTrollEr
4.3.4 Mounting
The Ezetrol®plus should be positioned at an easily read and accessed height. Siemens Water Technologies recommend that the centre of the display is at a height of 1650 mm.
Drill a 9mm hole, in a convenient position, in each corner of the backboard.The holes in each corner of the board should be used to pass an 8mm bolt through. The fixing should be passed through the mounting board and one of the spacers supplied, at each corner.
The board should NOT be fixed directly against the wall, as this would cause damage to the sensor leads that are passed through the back of the board. Spacers are provided to hold the board away from the wall.
4.3.5 Samplewatersupply
Required pressure at flow cell.Minimum 0.25 barMaximum 4.0 bar
A flow of approximately 30 l/hr is required for the accurate operation of the chlorine sensor; the flow regulator automatically limits the amount of water flowing through the cell. A flow in excess of 30 l/hr would be held within the sample water sample pipe work and will eventually pass through the flow cell. It is important to use the hose supplied and not to increase the bore of the water supply pipe to prevent undue lag-time between the water entering the sample hose and passing the sensor tips.
�5WT.050.425.00�.GE.IM.0�09
Ezetrol®plus analysEr/controllEr
Water from the flow cell is normally fed to the drain. It is also possible to return the ‘waste’ water back to a post filter point in the pool water return, at a maximum back pressure of 1.5 bar. A return water installation kit of parts is available.
If the flow cell sample supply water pressure is less than 0.25 bar, a sample water pump may be installed either from the pool or from the circulation system (preferred). The use of a booster pump must include a loop of pipe work with a sample tapping to draw of a proportion of the water to pass through the sample cell. This prevents the entire pump pressure from being put directly onto the flow regulator and also stops the creation of an artificial lag time.
The sample water supply point must be installed in the delivery pipework between the circulation pump(s) and the filters. However, the sample water point must be installed upstream of the flocculant dosing station an the pressure applied directly to the measuring cell must be at least 0.2 bar. The sample water point must be chosen to ensure that the water sample is representative with a constant, bubble-free flow. The sample supply hose is supplied with the kit of parts. The sample line should be as short as possible. If the sample line is to be longer than 30m refer to Siemens Water Technologies.
A sample strainer must be fitted to ensure that the flow switch, flow regulator and sensors cannot be fouled or damaged by solids passing from the circulation pump supply.
Failure to use the strainer provided will allow debris such as ‘hair & lint’ to pass into the flow regulator and the flow cell. This will compromise the performance of the Ezetrol®plus and will invalidate the warranty.
For sample runs of 20m upwards, a loop from the circulation pump delivery pipework should be taken to a point below or adjacent to the board mount assembly and returned to the suction side of the circulation pump(s).
The sample loop should be run in ½” uPVC pipe, suitably supported throughout its entire length. A ½” tee adjacent to the flow cell should be fitted and a minimal length of 5/16" hose and connected to the adapter on the strainer inlet, out let and then on the to the flow switch mounted directly under the flow cell. The fittings from the tee to the flow cell are included the ½” uPVC pipe and fitting are to be supplied by others.
Please note that if 50% duty circulation pumps are employed, running only one pump only will reduce the sample rate of flow to the flow cell.
WT.050.425.00�.GE.IM.0�09��
Ezetrol®plus analysEr/conTrollEr
Attention should be given to the amount of flow during this period and, if adjusted, the subsequent flow when the second pump flow is restored.
Should the ‘waste’ water be returned to the post filter circulation pipe work remove the ‘tundish’ from the board and the threaded insert, plus the spare threaded insert, used to support an isolation valve.
4.3.6 sensor connection
Remove protective caps from the pH and chlorine sensors. Screw sensors into the flow cell. The chlorine sensor has an integral lead that can not be removed from the sensor. The back nut/thread on the sensor may be screwed into the flow cell without rotating the sensor or ‘knotting’ the lead.
There should be no air bubbles in the tip of the pH sensor, if there are, remove them by gently shaking the sensor (similar to shaking a clinical thermometer).
After start-up, all sensors require a settling-down period of approximately two - four hours. Calibration and other adjustments should only be made after this period and automatic feed control should be switched off. The Ezetrol®plus should not be left in automatic feed mode overnight for 24 hours after first fitting the sensors.
Do not use stabilised chlorine products, as the Ezetrol®plus will not function correctly.
Sensor warranty will be void if the above is not complied with.
4.3.7 Electricalconnections
Only those persons qualified to carry out electrical installation works should undertake the installation of electrical wiring of an Ezetrol®plus.
The electrical supply to the board assembly should be wired via a double pole isolation switch. The supply should be fused at 10 amp max and the location of the fuse clearly identified.
Please refer to wiring diagrams at the rear of this manual for identification of all the terminals to enable cable connection.
The Ezetrol®plus is not provided with internal dosing relay fuses. To ensure the relays and PCB are protected external fuses must be fitted.

WarnInG: The Ezetrol®plus is designed to be permanently powered. The main power into the unit should NOT be interlocked with main circulation pumps. The controller has a secondary input (external stop), which is used to isolate the dosing pump outputs. This input is volt-free and must not be powered (or the controller will be damaged).
