Specification Catalogue 20152016 Water Efficient Washroom Controls Urinal Flushing WC Flushing Washroom Control Taps Spouts Limescale Prevention Our early days Research and development Cistermiser today The company developed its first product a hydraulic urinal flush control valve in 1976 at a time when there were no regulations stipulating that companies had to minimise water consumption in the washroom. The desire to conserve water and promote washroom hygiene is the key driver of Cistermisers ongoing investment in new product development. Two low pressure derivatives of the hydraulic valve were developed during the 1980s before the company added its first domestic product a limescale prevention device called Combimate to its range in 1987. Investment in RD led to the development of electronic technologies and the company launched a complete washroom control and the infrared urinal flush control valve in the early 1990s. In recent years the companys product portfolio has expanded into all areas of the washroom with a range of WC and urinal flushing devices a series of infrared taps spouts and Sensazone an advanced system to manage water and energy. Today the Cistermiser name is synonymous with quality and reliability and has become a generic term for all urinal flush controls. We now offer solutions for commercial industrial and public sector washroom environments where security hygiene and cost reductions are required. www.cistermiser.co.uk Cistermiser has been designing and manufacturing a range of high quality cost effective water-efficient products for over 35 years.

Products Services Cistermiser produces a range of products which control all the water outlets in a commercial washroom. Several of our products can also be used in domestic applications. Urinal Flushing Our range of urinal flush control valves includes the Hydraulic Urinal Flush Control Valve and electronic Infrared Control Valve for use in urinal installations where a cistern is used to flush the urinals. The Direct Flush urinal valve is an intelligent product which detects when someone is using the urinal and only flushes after that person has left it. This valve has been specifically designed for flushing urinals directly from the mains water supply. WC Flushing Easyflush is a no-touch WC flushing valve with dual flush from a single sensor. We also offer Easyflush Direct allowing WCs to be flushed directly from the mains water supply. Taps Spouts Cistermisers range of infrared taps and spouts can be either basin or panel-mounted. Anti-Vandal Range This is a secure range of products designed for use in high risk and challenging environments. This complete washroom solution offers robust heavy duty vandal-proof shower spouts basin spouts urinal and WC flushing. Washroom Control Cistermisers Sensazone range controls the water supply lighting and extractor fans within the washroom. Our Sensazone product controls the supply of hot cold and rain or grey water into the washroom isolating the supplies in vacant periods. Limescale Prevention Cistermiser also manufactures the Combimate a limescale prevention device for use with combination boilers and whole house water heaters in domestic settings. Technical Support Our technical support team is trained to deal with any technical queries or issues with our products post-installation.

Quality Warranty Information All Cistermiser products are WRAS approved and the company is ISO 90012008 certified. All products have a one year parts only warranty from the date of manufacture. The warranty can be extended free of charge to three years from date of installation. to our 2015 Specification Catalogue designed as a guide to help you choose the most appropriate product for your particular application. www.cistermiser.co.uk 5 Our commitment Cistermiser has a long-established record of dedication to conserving water our first water-saving product was launched soon after the 1976 drought. We have always recognised the need to reduce water wastage and our product range reflects this commitment. Our infrared range of products has been recognised as water efficient under the Waterwise Marque and the European Water Label Scheme. We have developed a water efficiency rating chart to show just how much water our products save compared to standard products. The adjacent chart indicates the achievable savings as a result of installing one of our urinal flush controls see page 11 for more details. Water usage in the UK has been rising by 1 a year since 1930. 1.2 billion litres of water are flushed needlessly away every day in the UK. Urinals operating without flush controls can use up to 160000 litres of water a year. Millions of WCs installed in the UK have a flush capacity of 13 litres or even more. A conventional tap installed on typical commercial premises can use over half a million litres of water a year. Despite the chronic shortage of water storage facilities in the UK each individual still uses approximately 150 litres per day this figure increases to over 3400 litres per person every day when embedded water consumption is considered. Water efciency The key to water efciency is reducing waste not restricting use.

To download the estimators you will need to register on www.breeam.orgindex These versions all look at the same broad range of environmental impacts Management Health and Wellbeing Energy Transport Water Material and Waste Land use and Ecology Pollution Credits are awarded in each of the above areas according to performance. A set of environmental weightings then enables the credits to be added together to produce a single overall score. The building is then rated on a scale of PASS GOOD VERY GOOD EXCELLENT or OUTSTANDING and a certificate is awarded to thedevelopment. As part of our commitment to water conservation we have assessed how our products can help a building design achieve BREEAM credits and hence a higher overall BREEAM rating. To achieve an OUTSTANDING rating for example a building design will need to obtain 2 credits under the Wat 01 category. You will find further details which can also be used to justify your choice of products in the following pages. Standard versions exist for common building types. Less common building types can be assessed against tailored criteria under the Bespoke BREEAM version. Buildings outside the UK can also be assessed using BREEAM International. BREEAM Building Research Establishment Environmental Assessment Method can be used to assess the environmental performance of any type of building new and existing. www.cistermiser.co.uk 7 Performance Standard 6 litre full flush with an adjustable part flush giving an effective flush volume of 4.5 litres.

The valve uses a simple patented mechanism which prevents water waste by ensuring that the auto-flush cistern is only filled and can only flush when the washroom is used. Automatic urinal flush control Unique patented hydraulic mechanism no electrical supply or batteries required Industry leader with half a million already installed Fit and forget quality and reliability Hygiene flush option for periods of non-use Ensures compliance with the Water Regulations On DEFRAs ECA Water Technology List purchase and installation are tax deductible How it works The Cistermiser Hydraulic Valve is installed on the supply pipe to the urinal cistern. The valve is activated by short-term pressure drops created by use of taps or WCs onthe same supply. The valve is normally closed when it is activated it opens and water passes to the urinal cistern until the pressures on both sides of the valve are equalised. When the cistern is full the auto-siphon will flush. Hygiene cycle In buildings where the washrooms are vacant for long periods a hygiene cycle attachment is available to ensure aregular flush every 12 hours to prevent washroom odours. The bypass screw should be set to permit a slow drip into the cistern to initiate a flush approximately every 12hours. For correct operation it is essential that the siphon of the auto flushing cistern does not leak. Product information The valve is installed on the supply pipe to the urinal cistern. The installer or user can adjust the time the valve remains open and therefore how long the cistern takes to fill and how much water is used. When the washroom is not being used the water supply pressure remains constant and the valve remains closed preventing water passing into the cistern. The cistern can therefore only flush during periods when the washroom is in use eliminating unnecessary water consumption and cost. www.cistermiser.co.uk 13 Choosing the right valve for your application Technical specification wording Three models make up the range of Hydraulic Valves each suited to a different range of water supply pressure. This table will help to specify the right model for your application.

The Cistermiser Hydraulic Valve consists of three main elements as shown left. Diaphragm operated valve which when opened allows water to pass to the urinal cistern. Hydraulic accumulator which if fully charged will maintain an equal supply-pressure on both sides of the diaphragm. When pressure on the inlet side is reduced as other services are used the pressure imbalance causes the valve 1 to open. Adjuster restrictor screw which can be set during installation to determine the volume of water discharged into the cistern at each operation by altering the duration of the open period. 1 2 3 1 2 3 Colour coded packaging Model Supply Operating sensitivity Standard Valve ...with Hygiene Flush Mains water or tank-fed systems above 5m head 15 of supply pressure Low Pressure Valve ...with Hygiene Flush Tank-fed systems 3m to 5m head 20 of supply pressure High Sensitivity Low Pressure Valve Tank-fed systems 0.5m to 3m head 20 of supply pressure 14 www.cistermiser.co.uk Infrared Control IRC Valve Cistern-flushing urinal valve with motion-sensing infrared Reduces water consumption by up to 80 The Infrared Urinal Flush Control IRC valve automatically manages the supply of water to a urinal cistern. The PIR sensor detects movement and activates the solenoid valve allowing water into a urinal cistern. Ensures compliance with the Water Regulations Can be concealed to reduce the risk of vandalism Battery or mains powered no external transformer required. IRC can use batteries as back-up power to mains supply if required. Pipe wall or ceiling mounted sensor surface mounted or recessed On DEFRAs Water Technology List purchase and installation are tax deductible Visible LED status indicator and low battery alert How it works The Infrared Urinal Flush Control IRC consists of asolenoid valve and the sensor module. When the IRC detects movement in the washroom a pulse from the sensor opens the normally-closed solenoid valve and water flows to the cistern at the same time the sensor is switched off. After 25 minutes the power is restored to the sensor and as long as no movement is detected for 5 minutes the solenoid valve closes shutting off the water supply to the cistern. Product information The solenoid assembly is plumbed in on the water supply to the urinal cistern. The connection to the infrared sensor is made either by directly mounting the sensor module on to the solenoid or by using the floating socket supplied for a remote mounting. If mounted remotely the sensor module may be Surface mounted using a standard pattress box. Recessed into a suspended ceiling using the ceiling mounting kit CMK supplied with the IRCas standard. If the sensor detects no occupancy in 12 hours it will automatically open the valve for 30 minutes to allow one flush of the cistern to rinse the urinals and pipework. The sequence is designed to maximise battery life giving approximately 3 years life from one good quality set of batteries. The flow rate of the water into the cistern is adjustable to maximise water economy. Generally this should be set so that the cistern flushes once every time the valve is opened. i.e. every 30 minutes during occupation.

The LED flashes green every 3 seconds whilst a user is detected. If a user is detected whilst the water is flushing the flush is automatically arrested to prevent splashing and wastage. During the flush the LED flashes green once a second. The flush duration is adjustable which ensures that only the minimum amount of water necessary is used. If there has been no use of the urinal for 12 hours the direct flush automatically runs a hygiene flush to prevent odours and the build up of uric acid in the pipework. Product information Direct Flush includes an integral DC pipe interrupter air gap enabling the installer to connect it directly to the mains water supply. This provides fluid category 5 back-siphonage protection without the need for any additional backflow prevention or check valves. Direct Flush can be powered by either mains electricity via the DC transformer or batteries both options are included as standard. When batteries are fitted the Direct Flush provides a low battery warning indicator. A mains power supply unit PSUC which powers up to 20 Direct Flush urinal valves is also available. Only 1 fused spur is required when using this product. Additional customised washroom settings are obtainable via a hand held remote control Infrared Configuration Unit ICU which is available as an optional extra. The remote controller enables rapid automatic range configuration to the specific washroom dimensions deactivation of the hygiene flush function and where a siphonic trap has been fitted activation of the trap refill function. The Direct Flush automatically flushes the individual urinal after use ensuring the highest level of hygiene from the minimum volume of water. Direct Flush removes the need for the auto-flush cistern and associated plumbing used in traditional urinal installations which flush all urinals intermittently even if they have not all been used. Direct Flush Discreet 18 www.cistermiser.co.uk Reducing water wastage and costs ensuring hygiene Uncontrolled urinals may flush constantly regardless of use wasting thousands of litres of water per year and costing hundreds of pounds per year. The Direct Flush is activated after every use of the urinal but flushes as little as 0.5 litre at a time.

The dual flush mode enables the user to select either a part or full flush by the length of time their hand is in front of the sensor. For a part flush the hand is held in front of the sensor for up to one second and for a full flush over one second. Easyflush Walkaway is normally activated by the user standing up or leaving the cubicle however it can also be activated by the user bringing their hand toward the sensor. The Walkaway version comes with the dual flush factory programmed. A part flush will be delivered if the user departs from the cubicle within 40 seconds and a full flush will be delivered if the user departs after 40 seconds. Product information Both the Wave and Walkaway sensors meet the DDA requirements and are Part M compliant. Easyflush is two interlinked valves in one a lift drop valve which empties the cistern and a delayed action float valve which controls refilling. It also includes an integral overflow pipe to preventflooding. The compact single-piece unit is located over the outlet by a bayonet-type locking device which simplifies installation. Intelligent memory feature If the user requires an additional flush they can bring their hand close to the infrared sensor to activate anautomatic further flush once the cistern has finishedrefilling. Easyflush is easy to install in retrofits or new installations. It can also be supplied with its own cistern. The Easyflush no-touch dual flush WC cistern valve promotes best practice in water economy and hygiene indomestic and commercial washrooms. www.cistermiser.co.uk 23 Installation options Delayed action valve operating sequence Reducing water wastage through delayed action Easyflush is powered by 4 x 1.5V AA LR6 batteries or a 6V DC mains adaptor which can be installed behind service panels. The battery option allows the Easyflush to be installed inside exposed cisterns. Also available as an optional extra is a multi product mains power supply unit PSUC to power up to 20 sensors from a single fused spur. The Easyflush Wave can be fitted into a concealed or an exposed cistern and can also be easily retrofitted. The Easyflush Walkaway is only suited to concealed installations. The inlet float valve operates with a delayed action which only allows the cistern to begin refilling after it has been completely emptied and the outlet valve has closed. This patented feature prevents an increase in the volume of water per flush. In other systems water can enter the cistern before the outlet valve has closed thus increasing the volume of water per flush. Installing a Cistermiser Easyflush can save up to 162000 litres per year as shown below. UK toilets needlessly flush away 1.2 billion litres of water a day Waterwise. The graph below adapted from WRc data shows that the actual flush volume for a nominal 6 litre WC increases as pressure increases.

WRAS approved BREEAM Wat 01 compatible product 26 www.cistermiser.co.uk Easyflush Direct is an electronic flushing system for WCs that removes the need for a WC cistern by taking its water feed straight from the mains supply. Effective flushing To achieve an effective and efficient flush the water system needs to deliver at least 90 lpm litres per minute. Typically this would require that the dynamic water pressure measured before the valve is at least 2bar. If 90 lpm cannot be achieved the flush will be less effective and a longer flush duration or multiple flushes may be required. This can result in water wastage. If the water flow rate exceeds 150 lpm splashing from the WC bowl may occur. Easyflush Direct is fitted with a flow regulator that will limit the flow rate to 100 lpm. However additional flow regulators for 90 lpm and 125 lpm are included to regulate the flow rate further if required. These flow regulators are colour coded Dark blue 90 lpm Black 100 lpm fitted as standard White 125 lpm Product information Easyflush Direct includes a valve DC pipe interruptor and sensor. When the sensor is activated the valve is activated for between 2 and 3.5 seconds supplying water to flush the WC direct from the mains water supply. After this period the valve closes and the flush is complete but can be activated again immediately. There are two versions to suit different applications Easyflush Direct Wave is operated by the user bringing their hand towards the infrared sensor. A part flush is triggered by holding ones hand in place near the sensor for about 1 second and a full flush is triggered by a slightly longer hand pass. Easyflush Direct Walkaway is activated when the user stands up or leaves the cubicle but it can also be activated by the user bringing their hand toward the sensor. A part flush is triggered by short user occupancy and a full flush by long user occupancy over 45 seconds. This means there is no cistern to be refilled and a second flush can be activated without a delay. A hygiene flush can also be activated to maintain the cleanliness of the WC. NOTE Some WC bowls are designed for low volume flushing and an effective flush can be achieved at low flow rates. Please check with the WC bowl manufacturer. The flow regulator can be removed to maximise flush performance but this can lead to excessive water use. www.cistermiser.co.uk 27 The flush volume is determined by the flush duration and the flow rate of the water supply. Using the flow regulators and adjusting the flush duration will allow you to configure the flush performance. However this will differ based on the WC bowl design. The flow rate can also be reduced by turning the adjuster screw in the middle of the valve clockwise to reduce flow or by fitting a third party pressure reducing valve above Easyflush Direct. Ensure that the dynamic water pressure pressure measured while the valve is open and water is flowing is sufficient to achieve the required flow rate. X Walkaway version only.

Also available as an optional extra is a multi-product mains power supply unit PSUC to power up to 20 sensors from a single fused spur. Easyflush Direct introduces an air gap into the water system. Care must be taken that pipework design and WC bowl selection is appropriate to ensure sufficient flow to flush the WC while preventing water flowing out of the air gap. This can occur when back pressure is high caused by a restrictive connection to the WC. The valve should always be installed as high as possible on the vertical pipe feeding the WC bowl flush inlet to prevent water backing up and leaking from the DC pipe interrupter. When installing the valve it is good practice to ensure there is an accessible isolation valve upstream of the valve. Ensure flow rate at valve does not exceed the flow rate to the WC bowl to prevent water backing-up to the DC pipe interrupter. Easyflush Direct is supplied with a DC pipe interrupter and a 1.5 flush pipe fitting. 126.25 66.90 126.25 66.90 67mm126mm 163mm 48mm 27mm 37mm www.cistermiser.co.uk 29 Taps Spouts Novatap Novaspout Vectatap Vectaspout Spouts 30 www.cistermiser.co.uk Hands-free infrared basin outlets Automatic shut-off no drips or taps left running Improve water and energy efficiency Easy to use ideal for less-abled or elderly Hygienic reduce risk of cross-contamination Available in 5 litres per minute and 3.5 litres per minute models Mains and battery powered options included Vandal resistant Easy to fit in new installations or retrofits Save water promote hygiene and reduce maintenance costs Infrared Taps Spouts Novatap Novaspout Vectatap and Vectaspout www.cistermiser.co.uk 31 The Novatap and Vectatap are deck- mounted chrome basin outlets supplied with sensor and control unit. The Novatap features a valve integral in its body making itextremely simple to install. The Novaspout and Vectaspout are elegant panel-mounted polished stainless steel basin spouts supplied with an infrared sensor control unit and valve. How it works The flow of water from the spouts is turned on when the user presents their hands to the infrared sensor which is located on the lower body of the Novatap and Vectatap or is positioned adjacent to the Novaspout and Vectaspout. No contact is required. When the users hands are moved away the flow of water stops after a 2 second delay. Product information Robust design and build quality make the spouts ideal for hard use environments where the less- abled or elderly may find it difficult to operate conventional spouts. The spouts are particularly useful where hygiene issues coupled with water and energy efficiency are paramount. Both the water flow run-on time and the sensor range between the spout and the users hands arefully adjustable. The spouts automatically switch off after 60 seconds of continuous flow preventing any water wastage if there is attempted vandalism. To prevent the potential build up of stagnant water which can create legionella bacteria growth the spout incorporates a hygiene rinse option which operates 12 hours after the last use of the spout. Additional spout lengths are available. Please contact Cistermiser directly for further information. The Water Regulations require that the flow rate of a spout does not exceed 3.6 litres per minute where basins have no plug. The 3.5 litres per minute model therefore ensures that this spout is compliant in such applications.

When touched the button causes an electronically operated valve to open and allow water to flow from a hand basin spout or shower head or the flushing of a WC or urinal. The flow duration for each outlet is programmed on installation. If the user touches the button for a second time within the programmed flow period water flow is stopped at once. There are no moving parts within the piezo touch button. The buttons are hard-wired to the anti-vandal six-channel controller which controls the outlets. Each unit can control up to six valves and each piezo touch button controls one outlet. Key features and benefits Cistermisers Anti-Vandal range is easy to install and is designed to offer the highest possible levels of tamper-proof security and remote control while at the same time saving water and minimising running costs through the use of latching solenoids. Each channel terminal fitting can be programmed tooperate differently to other channels or all channels can be programmed with the same operating characteristics flush duration hygiene rinse flush etc.. Each channel has a hygiene rinse facility which may be programmed to activate water outlets WC or urinal flush 12 hours after their last use to minimise legionella risk and maintain the integrity of waste pipetraps. Alarms and messages from the six-channel controller can be directed to a building management system ifpresent or fed directly to visual or audible indicators as necessary. A remote disable function allows the water supply tobe turned off from one central location which offers additional security and further eliminates the risk offlooding. The system is powered by extra low voltage supplied from the multi-product power supply unit which can power up to 10 control units and 60 individual Anti-Vandal range washroom products. Minimising running costs There are two standard types of simple onoff 22 solenoid valves latching bi-stable and non-latching mono-stable. Latching valves typically need a pulse of up to 50 milliseconds to open and a reverse polarity pulse of the same length to close. Non-latching valves must be powered for the entire open time. Assuming solenoids of equal power 2W for a 10 second open time A latching solenoid would use 0.2J of power or 0.056E-6 kWh. A non-latching solenoid would use 20J of power or 5.6E-6 kWh 100 times as much.

When touched the button causes an electronically operated valve to open and allow water to flush your WC cistern. The flow duration for each outlet is programmed on installation. If the user touches the button for a second time within the programmed flow period water flow is stopped at once. There are no moving parts within the piezo touch button. The buttons are hard-wired to the anti-vandal six-channel controller which controls the outlets. Each unit can control up to six valves and each piezo touch button controls one outlet. Flush Valve Options The Anti-Vandal WC system can be installed with either a cistern-mounted valve or a direct supply valve. The cistern valve option utilises the durable Easyflush valve see page 21 that offers a flush outlet and delayed action fill inlet valves combined in one unit. The direct flush option utilises the Easyflush Direct valve see page 25 that removes the need for a cistern and offers the advantage of an immediate re-flush. Product information The touch buttons are made from robust AISI 316L stainless steel. They come with anti-rotation washers and pins to ensure they cannot be removed or tampered with and used for self-harm or to inflict harm on others. The touch buttons are available in a choice of three tail lengths to accommodate panelwall thicknesses from 17mm to 330mm. The piezo touch button is supplied with 3 metres of cable to allow maximum flexibility for sitting of the valves and control box. System users only have access to touch buttons and WC bowls.

Keeps pipework clear and energy costs down Prevents brown water protects pipework and keeps maintenance costs down Compact flexible and quick to install on vertical and horizontal pipework with top or bottom entry For single appliances or whole house water supply Safe for drinking water and all domestic appliances 100 food grade material FAOWHO approved and compliant with EN 1208 No maintenance. Easy annual Combiphos top-up WRAS approved Combiphos a polyphosphate compound is 100 food grade material approved by FAOWHO and compliant with the European normative standard BS EN 1208 that prevents scale build-up and soft water corrosion in combination boilers and other domestic hot water appliances.

This action prevents the formation of scale while retaining the health benefits of the natural minerals contained in hard water. Combiphos coats the inside of the pipework boiler heat exchanger and appliances with a non-residual microscopic protective coating to prevent scale-causing minerals from accumulating and aggressive soft water from corroding the system and appliances. Tried and tested Combiphos is a polyphosphate compound specifically developed to provide the most effective limescale prevention in flow-through installations. Polyphosphate dosing has been safely used to treat water throughout the world for many years. Health and safety Combiphos is tasteless and odourless and contains a polyphosphate compound which is classified by the WHO as a food-grade additive. The quantity size and hardness of the spheres control the amount of Combiphos released. Typically this is less than 3ppm parts per million of phosphate in treated water and perfectly safe for human consumption. The Combimate de-scaling guarantee If Combimate is installed with a new boiler and the Combiphos is replaced annually Cistermiser guarantees that the new boiler new heat store or new heat exchanger will not scale up. Cistermiser is so confident in the capabilities of Combimate when used with Combiphos that if the unit it is protecting experiences significant scaling we will contribute up to 500 towards the cost of repair or replacement. Subject to Cistermisers warranty policy NOTE Combiphos does not soften water and its effectiveness may be reduced in water heated to temperatures above 60 degrees in water with carbonate hardness levels above 360ppm or at pH levels below 6.5. 50 www.cistermiser.co.uk There are two possible installations whole-house supply or single appliance Whole-house supply For this installation Combimate should be plumbed inafter the stop-valve on the cold water supply to the premises. The white removable divider tray should be removed from inside the Combimate dome in a whole house installation so that the dome can be completely filled with Combiphos. Single appliance installations Combimate can be used to protect a single appliance by placing it on the cold water supply to that appliance e.g. a boiler in which case the red removable divider tray should be left in place and Combiphos should only be put in the top half of the dome and this reduces the amount of Combiphos required. Inlet and outlet connections use 15mm or 22mm compression fittings depending on model. There is minimal pressure or flow rate loss through Combimate. Vertical top and bottom entry pipework can be used which ensures easy retrofit installation. Combimate should be installed at least 05m from any local sources of heat such as boilers orhot water pipes. The Combimate can be installed in various configurations allowing maximum flexibility of pipework configurations. 1.6mm or 116 of scale in a heating system causes a 12 loss in heating efficiency.
