Deterioration in performance can indicate the needfor service work on the valve and/ or the water supplies.Procedure1. Carry out the procedure 1. (a) to (c) and 2. (a) to (e) on page 38 using thesame measuring equipment, or equipment to the same specifications.2. If the mixed water temperature has changed significantly from the previous testresults (e.g. > 1 K), record the change and before re-adjusting the mixed watertemperature check:a) that any in-line or integral strainers are cleanb) any in-line or integral check valves or other anti-backsiphonage devices arein good working orderc) any isolating valves are fully open3. With an acceptable mixed water temperature, complete the procedure 2. (a)to (e) on page 38.4. If at step 2. (e) on page 38 the final mixed water temperature is greater thanthe values in Table A and / or the maximum temperature exceeds the corre-sponding value from the previous test results by more than about 2 K, the needfor service work is indicated.NOTE: In-service tests should be carried out with a frequency which identi-fies a need for service work before an unsafe water temperature can result. Inthe absence of any other instruction or guidance, the procedure described in„Frequency of in-service tests“ may be used.Frequency of in-service tests TMV Type 3*GeneralIn the absence of any other instruction or guidance on the means of determining theappropriate frequency of in-service testing, the following procedure may be used:1. 6 to 8 weeks after commissioning carry out the tests given in 2. on page 38.2. 12 to 15 weeks after commissioning carry out the tests given in 2. on page 38.3. Depending on the results of 1. and 4. several possibilities exist:a) If no significant changes (e.g. < 1 K) in mixed water temperatures arerecorded between commissioning and 1., or between commissioning and4. the next in-service test can be deferred to 24 to 28 weeks after commis-sioning.b) If small changes (e.g. 1 to 2 K) in mixed water temperatures are recordedin only one of these periods, necessitating adjustment of the mixed watertemperature, then the next in-service test can be deferred to 24 to 28weeks after commissioning.c) If small changes (e.g. 1 to 2 K) in mixed water temperatures are recordedin both of these periods, necessitating adjustment of the mixed watertemperature, then the next in-service test should be carried out at 18 to 21weeks after commissioning.d) If significant changes (e.g. > 2 K) in mixed water temperatures are re-corded in either of these periods, necessitating service work, then the nextin-service test should be carried out at 18 to 21 weeks after commissioning.4. The general principle to be observed after the first 2 or 3 in-service tests isthat the intervals of future tests should be set to those which previous tests haveshown can be achieved with no more than a small change in mixed watertemperature.*TMV Type 2: The frequency of performing the in-service tests is 1year maximum.Thermostatic AdjustmentTemperature LimitationThe temperature is limited by the safety stop to 40°C. If a higher temperature isrequired, it is possible to over ride the safety stop by depressing the safety button.NB. It is recommended that for private domestic use the maximum mixed watertemperature be set at the following factory set values:Shower Mixer 43°CBath/Shower 43°CFor healthcare applications the Temperatures must be set by following the proce-dures on page 34. This ensures that after correct installation the outlet temperatureof the water can never exceed 43°C.Temperatures can be set by following the procedures on page 34. This ensuresthat after correct installation the outlet temperature of the water can never exceed43°C.To guarantee a smooth running of the thermostatic element, it is necessary fromtime to time to turn the thermostat from total hot to total cold. The thermostatic mixervalve should be checked annually by a qualified person to ensure correct opera-tion.The mixer is fitted with check valves (page 37 pos. 96737000 and 93136000)and filters (page 37 pos 96922000 and 98282000). If the water flow dropsthe filters need to be cleaned. For that purpose please follow the steps 1 - 5 onpage 35.Calibrating ThermostatIf the temperature reading is different to the showering temperature, follow the steps1 - 6 on page 34.KEYIsolating valveReducing valveMixer ValvePumpUnvented System (pressure balanced)22 mm22 mmcold mains supplyPumped Systemcoldhothot28 mm22 mm22 mm22 mm22 mmcold mains supplyGas Combination Boiler (multi-point)15 mm15 mmcold mains supply
