SpecificationsImportant Points:1. The installation, commissioning and maintenance of this product must be carriedout in accordance with instructions given in this Manual, and must be conductedby designated, qualified and competent personnel.2. Installations must comply with all Local/National Water Supply AuthorityRegulations/Bye-laws, and Building and Plumbing (UK: BS6700) Regulations.3. Rada-Presto products are precision-engineered and should give continuedsuperior and safe performance, provided:• they are installed, commissioned, operated and maintained in accordancewith these recommendations• periodic attention is given as necessary to maintain the product ingood functional order. Recommended guidelines are given in section:'Maintenance'.4. Warning! Continued use of this product in conditions outside the limits listed inthis section can severely affect the performance and reduce the effective servicelife, and can present potential risk to users.Normal Operating Conditions are considered as:• inlet dynamic pressures nominally balanced to within 10% of each otherduring flow• Stop valves with check valves to isolate system supplies.• daily usage of 1-6 hours• installation and usage environment not subject to extremes of temperature,unauthorised tampering or wilful abuse.Operating Parameters:Temperature range:The temperature of stored water should never exceed 65°C. A stored watertemperature of 60°C is considered sufficient to meet all normal requirements andwill minimise the deposition of scale in hard water areas.Pressure:Minimum maintained pressure 0.15 barMaximum maintained pressure 10.0 bar

CommissioningCommissioning must be carried out in accordance with these instructions, and mustbe conducted by designated, qualified and competent personnel.Commissioning Checks1. Check inlet pipework for correct function of stop valves.2. Operate the tap and check:• Flow-rate is sufficient for purpose.• The connection to the supply is watertight.The flow control and flow time are preset at manufacture, however both may beadjusted, see below.Flow Rate Control SettingThe TF2000/TF2000S and TF2010S are factory set to flow position S4, which suppliesapproximately 5 l/min flow at 0.3 bar maintained pressure. Should the installationpressures require adjustment of the flow rate, any one of the five different flow ratepositions, S1 to S5 may be selected, with S5 being the least restrictive. Adjust theflow rate as follows:1. Isolate the water supply. Removethe tap knob and unscrew thehead assembly (refer to section:'Maintenance').2. Remove the head assembly andattached cartridge.3. Turn the adjusting ring (colouredblack on the TF2000 and green on theTF2000S/TF2010S) on the cartridgeclockwise or anticlockwise accordingto the flow rate required (refer toillustration and Flow Rate AdjustmentChart).Note! Taps are supplied set in positionS4.4. Install the cartridge and headassembly into the body (refer tosection: 'Maintenance').PositionVisible Aperture10+-Flow Rate ControlSetting AdjustmentS1 S2 S3 S4 S5(Refer to flow curves chart for pressure/flow rates)

OperationTF2000The TF2000 is simple to use. A firm push on the tap knob starts the water flowingfor the duration of the flow timing. The flow timing is factory preset but this can bealtered (refer to section: 'Commissioning'). If the tap knob is pushed again whilstthe tap is flowing a further preset cycle will commence.TF2000S and TF2010SThe TF2000S and TF2010S are fitted with the security "S" cartridge. The tap isoperated by a firm push on the tap knob, however, flow will not commence until thetap knob is released. The flow timing is factory preset but this can be altered (referto section: 'Commissioning'). If the tap knob is pushed again whilst the water isflowing the flow will cease. The tap knob will have to be released again to achievewater flow.Fault DiagnosisSymptom1. Tap not working (Noflow).Cause/Rectificationa. Check Inlet supplies.b. Remove the cartridge and clean the mechanismunder running water: refer to section: 'Maintenance'for removal.Note! Cartridges may only be cleaned by flushingthrough under a jet of clean water to removelodged particles. Do not descale. Cartridges arenot serviceable, and must not be dismantled.2. Tap will not shut off. a. Check the piston seal for cleanliness.b. Make sure that the spindle spring slides freely inits aperture.Refer to section: 'Maintenance' for removal.3. Tap shuts off tooquickly.a. Check the cleanliness of the sealing cap in thepiston.b. Check the spindle spring for damage.Refer to section: 'Maintenance' for removal.13

LubricantsImportant: Use only silicone-based lubricants on this product. Do not useoil-based or other lubricant types as these may cause rapid deterioration ofseals.Standard silicone-based lubricants may be used on all static seals, and threads, toassist refitting (e.g. Rocol MX22).Maintenance ProceduresMaintenance must be carried out in accordance with these instructions, andmust be conducted by designated, qualified and competent personnel.This tap series is designed for minimal maintenance under conditions of normaluse.Components are precision-made, so care must be taken while servicing to avoiddamage.When ordering spare parts, please state product type, i.e. Rada-Presto TF2000, andidentify part name and number (refer to the Spare Parts List).Protection against freezing: Turn off the incoming supply and push the tap severaltimes to drain the system.
