A final temperature check SHOULD be madeon-site to guarantee user safety, and that themixer falls within recommended ‘maximummixed water outlet temperatures’ - as statedon Page 12.FLOW REGULATIONA flow regulator is supplied for use with highpressure water systems. It may be fitted withany of the systems listed to reduce flow rate andassist economy.TO FIT THE FLOW REGULATORFit the flow regulator into the outlet fitting asshown in (fig.13).11

Thermostatic bar mixer showerTemperatureoverridebuttonFig.14TEMPERATURE ADJUSTMENT RANGEThe mixer has a temperature stop to preventaccidental rotation to higher temperatures. Thisis adjustable to provide a maximum temperatureof 35 C – 45 C.The mixed water temperature can be adjustedfrom cold through to a top limit (which canbe pre-set during installation – factory setat approximately 38 C) with full anti-scaldprotection throughout the range - SEE PAGE 17.Recommended outlet temperaturesFig.15The BuildCert TMV scheme recommends thefollowing set maximum mixed water outlettemperatures for use in all premises:44 C - for bath fill but see notes below.Temperaturespindle41 C - for showers.41 C - for washbasins.38 C - for bidets.The mixed water temperatures must neverexceed 46 C at terminal fitting.The British Burns Association recommends 37 to37.5 C as a comfortable bathing temperaturefor children. In premises covered by the CareStandards Act 2000, the maximum mixed wateroutlet temperature is 43 C.ADJUSTING THE MAXIMUMTEMPERATURE STOP SETTING Remove the end trim from the temperaturecontrol to allow access to the retainingscrew. Undo the retaining screw and pull thetemperature control off (fig.14). The maximum temperature stop does notneed to be removed. Turn the flow control to full flow. With asteady flow running, adjust the temperaturespindle until the temperature is about 38 C(fig.15). When the showering temperature issatisfactory turn off the shower. Refit thetemperature control, making sure the overridebutton aligns to 12 o'clock. Secure the temperature control in place withthe screw and fit the trim.12

Thermostatic bar mixer showerAPPROVALSThis mixer valve is approved to the requirements of:* BS EN 1111*On pressures above 0.5 bar.* WRASDesignation: HP-S (high pressure shower only)TMV2 REQUIREMENTS (12 MONTHLY VERIFICATION)It is a requirement that all TMV2 approved valves shall be verified against the original settemperature results once a year.On installation and on a yearly basis please perform the following checks:1. Cold water supply isolation testIsolating the cold water supply to the TMV, wait for five seconds if water is still flowing check thatthe temperature is below 46C.If there is no significant change to the set outlet temperature ( 2 C or less change from theoriginal settings) and the fail-safe shut off is functioning, then the valve is working correctly andno further service work is required.If there is a residual flow during the commissioning or the annual check this is acceptableproviding the temperature of the water seeping from the valve is no more than 2C above thedesignated maximum mixed water outlet temperature setting of the valve.Note:Temperature readings should be taken at the normal flow rate after allowing for the system to stabilise.The sensing part of the thermometer probe must be fully submerged in the water that is to be tested.FLOW CHART17

Thermostatic bar mixer showerMAINTENANCECleaningThe following maintenance procedure mustbe carried out for commercial and health carepremises, but is not necessarily required fordomestic installations.It is recommended that all products are cleanedusing warm, soapy water.Maintenance of the unit is required to givecontinued performance after installation and thatit continues to provide scald prevention.Do not use abrasive or aggressive chemicalcleaning products as this may affect the productsurface finish and invalidate your guarantee.Cleaning the filters (fig.A)Note: a thermostatic mixing valve in need ofmaintenance can be undetectable in normal useand only becomes apparent when a disruptionoccurs in the hot or cold watersupply temperatures or pressures.It is advised that this should be carried out by aqualified person.It is a requirement that all TMV2 approvedvalves shall be verified against the original settemperature results once every 12 months. Remove the filter housing and disassemble.a) Initially check the filters for debris once everythree months and clean if necessary. Turn off the water supplies before starting. To gain access to the filters remove the unitfrom the inlet fittings. Wash the filters thoroughly under runningwater, use a suitable brush to remove all debris. Reassemble and fit in reverse order.b) Perform a thermal shut off testevery three months, and check themaximum temperature setting. See the‘Commissioning’ section for the details ofthis test and readjustment of the maximumtemperature setting if required.Note: the filterhousing is Lefthand thread.non-return valve‘O’ ringc) If the maximum water temperature variesby more than 2 C from the commissionedsetting then carry out the following checksFilter Check the isolating valves are fully open. Check the internal surface for scaling.If the body requires descaling then it should beremoved from the pipework to carry this workout (all rubber parts MUST be removed beforedescaling). Check the function of the non-return valves.The non-return valves (NRVs) prevent cross-flowbetween hot and cold supplies under unequalpressure conditions. They are designed for longlife with no maintenance.Filter housingFig.ADisinfectionWhere chlorine is used for the disinfectionof water systems all relevant guidelines andapproved codes of practice must be strictlyfollowed. Failure to comply with the relevantguidelines and approved codes of practice mayinvalidate your guarantee.Note: the (NRV’s) will only operate in one direction- water should be able to flow into the unit from theinlets, but NOT back out through the inlets.WARNING!Do not use ‘powerful’ abrasive orsolvent cleaning fluids when cleaning theshower as they may damage the fittings.If these checks do not highlight the reasonfor the temperature variation, then internalcomponents will require replacement - please seethe spare parts list.18
