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 10 „Commisioning“.
NB. If a water supply is fed by gravity then the
supply pressure should be verified to ensure the con-
ditions of use are appropriate for the valve. Valves
operating outside of these supply conditions cannot
be guaranteed to operate as a TMV2 or TMV3 valve.
Recommended outlet temperatures
The BuildCert TMV scheme recommends the follow-
ing 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 tempera-
ture from the bath tap. The maximum temperature
takes account of the allowable temperature toler-
ances 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 Stand-
ards Act 2000, the maximum mixed water outlet
temperature is 43°C.

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
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.
Application Mixed water
temperature
Shower 43°C
Washbasin 43°C
Bath (44°C fill) 46°C
Bath (46°C fill) 48°C
f) record the equipment, thermometer etc. used
for the measurements
Table A: Guide to maximum stabilised
temperatures recorded during site
tests
The mixed water temperature at terminal fitting
should never exceed 46ºC.
If there is a residual flow during the commission-
ing 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.

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 (c) on page
10 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. >
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
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 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
TMV3*
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.
*TMV2: 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 46°C
Temperatures can be set by following the procedures
under „Setting thermostat to a maximum
temperature“. 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 15 pos.
9) and filters on the thermostatic element (page 15
pos 2). If the water flow drops the filters need to be
cleaned. Proceed as follows:
1. Remove the handle end cap, undo the screw
and pull off the handle and safety set disk.
2. Remove the faceplate, the sleeve and the spindle
extension.
3. Close the shut-off valves clockwise with an allen
wrench (8 mm).
4. Remove the thermostatic element, clean filters
and lubricate the seals.
5. Reassemble in reverse order and calibrate
unit.
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 (fig.1).
2. Undo the screw and pull off the handle (fig.2).
3. Rotate the handle so the button is positioned at
12 o clock and re-fit onto the spindle. (fig.3)

Cleaning
Cleaning materials for Mixers and
Showers
Acids are necessary ingredients of cleaning
materials for removing lime. However please pay
particular attention to the following points when
cleaning mixers and showers:
Only use cleaning material specifically intended
for this type of cleaning - such as Hansgrohe’s
Decalcifying Agent, available through the
specialist sanitary trade.
Never use cleaning materials which contain
hydrochloric, formic or acetic acid, as they
cause considerable damage.
Never use Phosphoric acid as it can cause
damage.
Never mix any cleaning material with another.
Never use cleaning materials on appliances with
an abrasive effect, such as unsuitable cleaning
powders, sponge pads or micro fibre cloths.
Cleaning Instructions for Mixers and
Showers
Please follow the cleaning materials manufacturer’s
inistructions. In addition pay attention to tlie
following points:
Clean the mixers and showers as and when
required.
The cleaning dosage and time the cleaner needs
to take effect should be adjusted according to
the product and the cleaner should not be left
longer than necessary.
Regular cleaning can prevent calcification.
When using spray cleaner, spray first into a
cloth or sponge never directly onto the sanitary
tapware, as drops could enter openings and
gaps and cause damage.
After cleaning, rinse thoroughly with clean water
to revove any cleaner residue.
Important
Residues of liquid soaps, shampoos and shower
foams can also cause damage, so rinse with clean
water after use.
If the surface is already damaged, the effect of
cleaning materials will cause further damage.
Damage caused by improper treatment will
not be covered by our guarantee.
Operating your Shower
Temperature Control
Turn the thermostat handle anti-clockwise to increase
the water temperature and clockwise to decrease
the water temperature.
