74Technical DataThis thermostatic valve will suit supplies of:HIGH PRESSURE (HP-S)Operating pressure: max. 10 barRecommended operating pressure: 1 - 5 barTest pressure: 16 barHot water temperature: max. 80°CRecommended hot water temp.: 65°CRate of flow: 26 l/min. @ 3 barMaximum outlet temperature: 43°C +/-*Safety check: 40°CHot water connection: Left handCold water connection: Right handMinimum difference between hotwater and mixed water temperature: 6 KHot and cold supply pressure should be balancedMixed water temperatureApplication Mixed water temperature(at point of discharge).Shower 41°C max.Washbasin 41°C max.Bath (44°C fill) 44°C max.Bath (46°C fill) 46°C max.* For preset outlet temperature adjustment – See page 63.NB. If a water supply is fed by gravity then the supplypressure should be verified to ensure the conditions of useare appropriate for the valve. Valves operating outside ofthese supply conditions cannot be guaranteed to operateas a TMV2 or TMV3 valve.Recommended outlet temperaturesThe BuildCert TMV scheme recommends the followingset maximum mixed water outlet temperatures for use inall premises:44°C for bath fill but see notes below;41°C for showers;41°C for washbasins.The mixed water temperatures must never exceed 46°C.The maximum mixed water temperature can be 2°C abovethe recommended maximum set outlet temperatures.Note: 46°C is the maximum mixed water temperaturefrom the bath tap. The maximum temperature takes accountof the allowable temperature tolerances inherent in thermo-static mixing valves and temperature losses in metal baths.It is not a safe bathing temperature for adults or children.The British Burns Association recommends 37 to 37.5°C asa comfortable bathing temperature for children. In premisescovered by the Care Standards Act 2000, the maximummixed water outlet temperature is 43°CInstallation RequirementsThis thermostatic mixer valve must be installed in comp-liance with current Water Regulations. If you have anydoubts about the Water Regulation requirements contactyour local water services provider or use the services ofa professional plumber.This mixer valve is suitable for use with the following watersupply systems:Gas Combination Boiler (multi-point) 1.0 - 10 bar*Unvented System (pressure balanced) 1.0 - 10 barPumped System 1.0 - 10 barIMPORTANT: If you install this mixer with a gravity fedsystem, there must be a minimum head (vertical distance)from the underside of tlie cold water storage tank to theshowerhead position of at least 5 metre.Before connecting the mixer, water should be flushedthrough the system to remove all debris that might otherwisedamage the valve.* If pressure is in excess of 3.5 bar, a pressure-reducingvalve should be fitted.Supply Conditions TMV2Operating pressure range High pressureMaximum static pressure - bar 10Flow pressure, hot and cold - bar 0.5 to 5Hot supply temperature - °C 55 to 65Cold supply temperature - °C 5 to 25Operating pressure range High pressureMaximum static pressure - bar 10Flow pressure, hot and cold - bar 1 to 5Hot supply temperature - °C 52 to 65Cold supply temperature - °C 5 to 20Supply Conditions TMV3
