Technical Data
This thermostatic valve will suit supplies of: HIGH PRESSURE (HP-S-T)
Operating pressure: max. 10 bar Recommended operating pressure: 1 - 5 bar Test pressure: 16 bar Hot water temperature: max. 70°C Recommended hot water temp.: 65°C Rate of flow: 36 l/min. @ 3 bar Maximum outlet temperature: 43°C +/-* Safety check: 40°C Hot water connection: Left hand Cold water connection: Right hand Minimum difference between hot water and mixed water temperature: 6 K Hot and cold supply pressure should be balanced
Mixed water temperature
Application Mixed water temperature (at point of discharge). Bidet 38°C max. 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 14 „Commisioning“. 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. Valves operating outside of these supply conditions cannot be guaranteed to operate as a TMV2 valve.
Recommended outlet temperatures
The BuildCert 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, 38°C for bidets. The mixed water temperatures must never exceed 46°C. 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 tlie cold water storage tank to the showerhead position of at least 5 metre.
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.

Bath / Shower Thermostat (positioned over a bath)
The thermostatic mixing valve must be installed in a position that is easily accessible for commissioning and future servicing.
1. The hot and cold water outlets should be 150 mm apart (plus or minus 12mm). Hot on the left and cold on the right (fig. 1). The recommended plumbing fittings are ½“ back plate elbows (not supplied).
2. Flush through the hot and cold water supplies.
3. Wrap PTFE tape round the S-unions and screw into the backplate elbows. The S-unions must protrude beyond the tiled surface between 32 and 41mm (figs.2-3).
4. Seal the gap between the S-unions and the tiles (fig.3).
5. Screw the escutcheons onto the S-unions.
6. Fasten the thermostatic mixer onto the S-unions using the union nuts. Align the unit and tighten the nuts (be careful not to damage the chrome finish). The S-unions allow inaccuracies to be compensated for.
Bath/Shower Thermostat (Fitting to the bath using
pillar unions).
The thermostatic mixing valve must be installed in a position that is easily accessible for commissioning and future servicing.
1. The pillar unions are designed to fit tap holes on a bath 180 mm apart with hot on the left and cold on the right (fig.4).
2. Flush through the hot and cold water supplies.
3. Place fibre washers into the holes of the chrome union nuts. (DO NOT USE FILTERS WHEN USING PILLAR UNIONS!)
From under the bath fit a large seal washer over the
thread then fix with the nuts.
4. Fasten the mixer onto the union pillars using the union nuts (be careful not to damage the chrome finish).

f) record the equipment, thermometer etc. used for
the measurements
Table A: Guide to maximum stabilised tem-
peratures recorded during site tests
Application Mixed water temperature
Shower 43°C Washbasin 43°C Bath (44°C fill) 46°C Bath (46°C fill) 48°C
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.
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 ope-
rating pressures for the designation of the valve
c) the supply temperatures are within the range per-
mitted for the valve and by guidance information on the prevention of legionella etc.
2. Adjust the temperature of the mixed water in accor-
dance with the manufacturer’s instructions 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
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 stabilised temperature
NOTE: The final stabilised mixed water temperature
should not exceed the values in Table A.
11
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 2. (a) to (e) on page 72
using the same measuring equipment, or equipment to the same specifications.
2. If the mixed water temperature has changed signi-
ficantly from the previous test results (e.g. > 1 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-line or integral check valves or other
anti-backsiphonage 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 (c) on page 10.
4. If at step 2. (e) on page 10 the final mixed water tem- perature 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 identifies 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 TMV2
The frequency of performing the in-service tests is 1 year maximum.
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 10.
2. 12 to 15 weeks after commissioning carry out the tests given in 2. on page 10.
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. 1 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 recorded 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.

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 46°C Bath/Shower Mixer when installed as type 3 valve the maximum mixed water temperature shall be set at 43°C for both outlets (bath & shower)
Temperatures can be set by following the procedures under „Setting thermostat to a maximum tem- perature“. 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 a qualified person to ensure correct operation.
The mixer is fitted with check valves (page 17 #96644000) and filters (page 17 #96922000). If the water flow drops the filters need to be cleaned. For that purpose the mixer has to be removed from the wall.
Calibrating Thermostat
1. If the temperature reading is different to the showering temperature, turn the thermostat handle until a 40°C reading is shown on your ther­mometer.
2. Remove the handle end cap, undo the screw (fig. 1).
3. Pull off the handle (fig. 2).
4. Remove the circlip from the spindle and slide off the locking ring (fig. 3).

Cleaning
Cleaning Recommendation for Hansgrohe Products
Today, modern sanitary and kitchen tapware, showers, accessories, washstands, sinks, tubs and radiators consist of very different materials to comply with the needs of the market with regard to design and functionality.
To avoid damage and reclamations, it is necessary to consider certain criteria when cleaning.
With regard to caring for the Hansgrohe products, the following must in principle be heeded:
• Only use cleaning material which is explicitly provided
for this type of application.
• Never use cleaning materials, which contain
hydrochloric acid, formic acid, concentrated caustic soda, chlorine pale lye or acetic acid, as they cause considerable damage.
• Phosphorus acidic cleaners are only conditionally
applicable.
• Mixing cleaning agents is not permitted, generally.
• Never use cleaning materials or appliances with an
abrasive effect, such as unsuitable cleaning powders, sponge pads or micro fibre cloths.
• The instructions of the cleaning agent manufacturers
have to be followed absolutely.
• Cleaning has to be carried out with a specified
cleaner dosage, contact time, object-related and adapted to the needs.
• The building up of calcifications has to be removed by
cleaning regulary.
• When using spray cleaners, spray the cleaning
solution onto a soft cloth or sponge, never directly onto the Hansgrohe products, as the atomised spray could enter openings and gaps in the Hansgrohe products and cause damage.
• After cleaning rinse thoroughly with clean water to
remove any cleaner residue.
• The use of steam cleaners is not permitted. The high
temperatures can damage the products.
Important
Residues of toiletries such as liquid soaps, shampoos and shower gels, hair dyes, perfumes, aftershave and nail varnish can also cause damage.
Here too: Carefully rinse with water after use to remove residues.
Likewise, do not store any cleaning agents or chemicals under the products, for example in a vanity unit, as the vapours may damage the products.
The damage of already damaged surfaces will deteriorate under the effect of the cleansers.
Components with damaged surfaces must be exchanged, otherwise there could be an injury danger.
