Technical Data
This thermostatic valve will suit supplies of:
This thermostatic valve will suit supplies of:
HIGH PRESSURE (HP-S / HP-T)
Type 3 High Pressure shower HP-S only
Type 2 High Pressure shower or tub as appropriate HP-S and or HP-T

Mixed water temperature
Application| Mixed water temperature (at point of discharge).
Shower| 41°C max.
Washbasin| 41°C max.
Bath(44°Cfill)| 44°C max.
Minimum difference between hot water and mixed water temperature:| 6 K

Hot and cold supply pressure should be balanced

• For preset outlet temperature adjustment – See page 33.
  NB. If a water supply is fed by gravity then the supply pressure should be verified to ensure the conditions of use are appropriate for the valve.
  Recommended outlet temperatures
  The TMV scheme recommends the following set maximum mixed water outlet temperatures for use in all premises:
  44°C for bath fill but see notes below;
  41°C for showers;
  41°C for washbasins.
  The maximum mixed water temperature can be 2°C above the recommended maximum set outlet temperatures.
  Note: 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.

Installation Requirements

This thermostatic mixer valve must be installed in compliance with current Water Regulations. If you have any doubts about the Water Regulation requirements contact your local water services provider or use the services of a professional plumber.
This mixer valve is suitable for use with the following water supply systems:
Gas Combination Boiler (multi-point) 1.0 – 10 bar*
Unvented System (pressure balanced) 1.0 – 10 bar
Pumped System 1.0 – 10 bar
IMPORTANT: If you install this mixer with a gravity fed system, there must be a minimum head (vertical distance) from the underside of tile cold water storage tank to the showerhead position of at least 5 metres.
Before connecting the mixer, water should be flushed through the system to remove all debris that might otherwise damage the valve.

• If pressure is in excess of 3.5 bar, a pressure-reducing valve should be fitted.
  Supply Conditions TMV Type 2

Supply Conditions TMV Type 3

Valves operating outside these conditions cannot be guaranteed to operate as Type 2 or Type 3 valves.

Commissioning and in-service tests

Commissioning
Purpose
Since the installed supply conditions are likely to be different from those applied in the laboratory tests it is appropriate, at commissioning, to carry out some simple checks and tests on each mixing valve to provide a performance reference point for future in-service tests.
Procedure

1. Check that:
   a) the designation of the thermostatic mixing valve matches the intended application
   b) the supply pressures are within the range of operating pressures for the designation of the valve
   c) the supply temperatures are within the range permitted for the valve and by guidance information on the prevention of legionella etc.

2. Adjust the temperature of the mixed water in accordance with the manufacturer’s instructions (page 33) and the requirement of the application and then carry out the following sequence:
   a) record the temperature of the hot and cold water supplies
   b) record the temperature of the mixed water at the largest draw-off flow rate
   KEY| Isolating valve
   ---|---
   | Reducing valve
   | Mixer Valve
   | Pump

c) record the temperature of the mixed water at a smaller draw-off flow rate, which shall be measured
d) isolate the cold water supply to the mixing valve and monitor the mixed water temperature
e) record the maximum temperature achieved as a result of (d) and the final stabilized temperature
NOTE: The final stabilized mixed water temperature should not exceed the values in Table A.
f) record the equipment, thermometer etc. used for the measurements

Table A: Guide to maximum stabilized temperatures recorded during site tests

The mixed water temperature at terminal fitting should never exceed 46ºC.
If there is a residual flow during the commissioning or the annual verification (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 outlet temperature setting of the valve.
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.
Any TMV that has been adjusted or serviced must be re-commissioned and re- tested in accordance with the manufacturers’ instructions.
In-service tests
Purpose
The purpose of in-service tests 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 the water supplies.
Procedure

1. Carry out the procedure 1. (a) to (c) and 2. (a) to (e) on page 38 using the same measuring equipment, or equipment to the same specifications.

2. If the mixed water temperature has changed significantly from the previous test results (e.g. > I K), record the change and before re-adjusting the mixed water temperature check:
   a) that any in-line or integral strainers are clean
   b) any in-fine or integral check valves or other anti-back siphonage devices are in good working order c) any isolating valves are fully open

3. 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 than the values in Table A and/or the maximum temperature exceeds the corresponding value from the previous test results by more than about 2 K, the need for service work is indicated.
   NOTE: In-service tests should be carried out with a frequency which iden6 fees a need for service work before an unsafe water temperature can result. In the 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*

General
In the absence of any other instruction or guidance on the means of determining the appropriate 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 are recorded between commissioning and 1., or between commissioning and 4. the next in-service test can be deferred to 24 to 28 weeks after commissioning.
   b) If small changes (e.g. 1 to 2 K) in mixed water temperatures are recorded in only one of these periods, necessitating adjustment of the mixed water temperature, then the next in-service test can be deferred to 24 to 28 weeks after commissioning.
   c) If small changes (e.g. I to 2 K) in mixed water temperatures are recorded in both of these periods, necessitating adjustment of the mixed water temperature, then the next in-service test should be carried out at 18 to 21 weeks 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 next in-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 is that the intervals of future tests should be set to those which previous tests have shown can be achieved with no more than a small change in mixed water temperature.

*TMV Type 2: The frequency of performing the in-service tests is 1 year maximum.

Thermostatic Adjustment

Temperature Limitation
The temperature is limited by the safety stop to 40°C. If a higher temperature is required, 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 water temperature be set at the following factory set values:
Shower Mixer 43°C
Bath/Shower 43°C
For healthcare applications the Temperatures must be set by following the procedures on page 34. This ensures that after correct installation the outlet temperature of the water can never exceed 43°C.
Temperatures can be set by following the procedures on page 34. This ensures that after correct installation the outlet temperature of the water can never exceed 43°C.
To guarantee a smooth running of the thermostatic element, it is necessary from time to time to turn the thermostat from total hot to total cold. The thermostatic mixer valve should be checked annually by o qualified person to ensure correct operation.
The mixer is fined with check valves (page 37 pos. 96737000 and 93136000) and filters (page 37 pas 96922000 and 98282000). If the water flow drops the filters need to be cleaned. For that purpose please follow the steps 1 – 5 on page 35.
Calibrating Thermostat
If the temperature reading is different to the showering temperature, follow the steps 1 – 4 on page 33.
