Assembly Procedure
• Thevalvebodyisclearlymarkedwith“C”andablueindicatorforcoldand“H”andared
indicator for hot.
• The use of sealing compounds is not recommended.
• Beforeinstallation,thehotandcold-waterinletofthemixingvalvemustbeclearofdebris.
the valve must be correctly connected to the respective supplies.
• Isolationvalvesmustbettedadjacenttothevalveinlet.APressurereducingvalve(PRV)
 mustbettedifdeemednecessary.
• Check the main valve assembly bores are free of debris and the end sealing faces are
clean.
• Checkthetwotailpiecesandconrmtheyarecompletewithunionnutsandcompression
nuts with olives.
• Insertthesealingwasherintotheinletsandoutletandscrewtheinletandoutletttings
 ontothevalvebody,takingcarenottoovertighten.
• Removethecompressionnutsandolivesfromthetailpieces.Locatetheinletlterscreens
and insert them into the bore of the tailpieces up to the shoulder.
• Assemble the valve to the pipe work and ensure the hot and cold-water pipes have full
 penetrationintothetailpieces.Thecompressionttingssuppliedallowfordirect 
connection to BS 22mm OD tube or BS 15mm OD tube.

• Tighten the compression nuts ensuring that the end of the pipe remains in contact with the
 lterelement.
• After installation check carefully for leaks.
• Thevalvemustalwaysbettedinalocationwhereitisaccessibleforbothtestand 
maintenance.

7. Commissioning & Adjustment
•  TheAlbionART33thermostaticmixingvalveissuppliedfactorypre-setat41--43°C. 
 However,installationconditionswilldictate,thattheproductbeadjustedonsite.
•  Priortocommencingcommissioning,thefollowingchecksshouldbecarriedout
• The designation of the TMV matches the application.
• The supply pressures and temperatures are within the operating range of the valve.
 • Isolatingvalvesaretted.
• The supply temperatures are within the range permitted for the valve and by
guidance information on the prevention of legionella etc.
•  Ifalltheseconditionsaremet,proceedtosetthetemperatureasbelow:-
• Remove the protective cap on top of the valve.
  • Back-outthenutusingahexagonwrench:
   o Toincreasethetemperature,turnclockwise
   o Todecreasethetemperature,turnanti-clockwise

7
TMV3 ART 33 Screwed Rev 1
• Temperature is in accordance with the valve application as per the table below: -
HP (1.0 – 5.0 Bar)
High Pressure
LP (0.2 – 1 Bar)
Low Pressure Application Maximum Temperature (°C)
HP-B LP-B Bidet 38
HP-S LP-S Shower 41
HP-W LP-W Wash Basin 41
HP-T44 Bath 44
• When the valve has been installed with the correct conditions of use it is advised that
the valve is subjected to normal operation prior to the commissioning at the application
temperature. Operate the valve from full cold to full hot at least three times by removing
 theblueplasticcapandusingahexagonwrenchtoadjust.
• With the valve at the full cold position bring the valve to the correct application
 temperaturebyturningthenutclockwise.Ifthevalveexceedsthistemperature,returnthe 
 valvetothefullcoldcondition,andresetittothecorrecttemperature+0-2°C.Donotseta 
valve with a lowered temperature as this will not provide consistent operation.
• After adjustment replace the cap to lock the valve in position and prevent tampering.
• Commissioning Test sequence
 •Afteradjustingthetemperatureofthemixedwaterinaccordancewiththevalveapplication.
• Record the temperature of the hot and cold-water supplies.
• Recordthetemperatureofthemixedwateratthelargestdraw-offowrate.
• Recordthetemperatureofthemixedwateratasmallerdraw-offowrate,whichshallbe 
measured.
• Isolatethecold-watersupplytothemixingvalveandmonitorthemixedwatertemperature 
 recordingthemaximumtemperatureachievedandthenalstabilizedtemperature.
• Recordtheequipment,thermometeretc.usedforthemeasurements.
•  Thenalstabilisedtemperaturemustnotexceedthevaluesinthetablebelowandmust 
 neverexceed46°C:-

•  46°Cisthemaximummixedwatertemperaturefromthebathtap.Themaximum 
temperature takes account of the allowable temperature tolerances inherent in
 thermostatic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 as a comfortable bathing
 temperatureforchildren.InpremisescoveredbytheCareStandardsAct2000,  
 themaximummixedwateroutlettemperatureis43°C.
8. Maintenance & In-Service Testing
• The purpose of in-service testing is to regularly monitor and record the performance of the
 thermostaticmixingvalve.Deteriorationinperformancecanindicatetheneedforservice
 workonthevalveand/orwatersupply.
• Carry out the test sequence using the same or equivalent equipment used for
commissioning the valve.
•  Ifthemixedwatertemperaturehaschangedsignicantlyfromtheprevioustestresults
 (e.g.>1°C),recordthechangeandbeforere-adjustingthemixedwatertemperaturecarry
out the following checks;
 • Allin-lineorintegralltersareclean.
• Any in-line or integral non-return valves or other anti-back siphonage devices are in
good working condition.
• Any isolation valves are fully open.
•  Withanacceptablemixedwatertemperature,completethetestsequenceaspersection7
of this document.
•  Intheabsenceofanyotherinstructionorguidance,itisrecommendedthatIn-Service
 Testsarecarriedoutasperthetablebelow.Ifthetemperatureisoutsideoftheexpected
range it will be necessary to remove and clean the valve in accordance with the
instructions in the table below: -
Temperature Variation (°C) Comment Service Frequency (Weeks)
+/-1°C N/A 24 – 28 Weeks
+/-1°C–2°C In either one period 24 – 28 Weeks
+/-1°C–2°C In both periods 18 – 21 Weeks
+/-Exceed2°C In either period 18 – 21 Weeks
• Ifthereisaresidualowduringthecommissioningorbi-annualverication(cold 
water supply isolation test) then this is acceptable providing the temperature of the water
 seepingfromthevalveisnomorethan2°Cabovethedesignatedmaximummixedwater

• Ifawatersupplyisfedbygravitythenthesupplypressureshouldbeveriedtoensurethe
conditions of use are appropriate for the valve.
• Thettingofisolationvalvesisrequiredascloseasispracticabletothewatersupply 
 inletsofthethermostaticmixingvalve.
• Temperaturereadingsshouldbetakenatthenormalowrateafterallowingthesystem
 tostabilize.Thesensingpartofthethermometerprobemustbefullysubmergedin 
the water that is to be tested. Any TMV that has been adjusted or serviced must be re-
commissioned and re-tested in accordance with the manufacturer’s instructions.
• Intheabsenceofanyotherinstructionorguidance,itisrecommendedthatIn-service 
Tests are carried out once every 6 months as a minimum.
9. TMV Cleaning Instructions
• Most domestic water supplies contain calcium which will separate out when the water is
heated in a system. The degree and speed of scaling may vary depending on factors such
 aswaterowrates,systemdesign,thehardnessofthewaterandthetemperatureto 
which the water is heated.
•  Depositsofscalemayovertimeforminthevalve,particularlyatthehotinlet.The 
formation of the scale may adversely affect the performance of the valve which will be
detected during the in-service testing. If this occurs it will be necessary to remove
the valve for de-scaling and service.
Cleaning Procedure
• Isolate the hot and cold supply.
• Remove the valve to a clean working area.
• Remove the protective cap.
• Unscrew the headwork of the valve.
• Carefully remove the temperature sensitive thermal element and piston assembly and put
to one side.
• Removethemainspringandowguideandcarefullyputtooneside.
• Inspect the components for contamination or damage.

TMV3 ART 33 Screwed Rev 1
• Clean or replace as necessary.
• There may be a need to periodically grease components. Please ensure that the grease is
WRAS approved.
• Remove the O-ring.
• Clean the valve body and headwork using a propriety de-scaler.
• Thoroughly rinse the body and headwork in clean water.
• CarefullytO-ringtobody.
• Carefullyre-tallcomponentsandperformthecommissioningsequence.
