• The valve body is clearly marked with “C” and a blue indicator for cold and “H” and a red
indicator for hot.
• 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.
• Assemble the valve to the pipe work and ensure the hot and cold-water pipes have full
penetration into the tailpieces.
• After installation check carefully for leaks.
• Thevalvemustalwaysbettedinalocationwhereitisaccessibleforbothtestand 

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
• Temperature is in accordance with the valve application as per the table below: -
HP (0.5 – 5.0 Bar)
High Pressure
LP (0.1 – 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-T Bath 46

TMV2 ART 33 Screwed Rev 1
• 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: -
Application Max Temperature °C
Bidet 40
Shower 43
Wash Basin 43
Bath 46 (note 1)
Note 1
• 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 once every 12 months as a minimum. If the temperature is outside
of the expected range it will be necessary to remove and clean the valve in accordance
with cleaning procedure prior to recommissioning.
• 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° above the designated maximum mixed water
outlet temperature setting of the valve.
• 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.
• 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.

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.
• 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.
