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

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
12 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
12.
4. If at step 2. (e) on page 12 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
The frequency of performing the in-service tests is
1year 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 12.
2. 12 to 15 weeks after commissioning carry out the
tests given in 2. on page 12.
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 cross
handle.
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 18 pos.
7) and filters on the thermostatic element. 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 (fig.1).
2. Remove the handle end cap, undo the screw and
pull off the handle and safety set disk (fig.2).
3. Rotate the cross handle so the marking point is
positioned at 12 o clock (fig. 3) and re-fit onto
the spindle. Replace the screw (fig.4).

Operating your Shower
The shower pipe has two controls built onto the
handle assembly.
Flow ON/OFF Control
The lever part of the handle is the volume control
/ diverter. When it is pointing straight down, it is
in the off position Turn the lever clockwise to send
water to the showerhead (fig. 1), anti-clockwise to
send water to the handshower (fig. 2). The further the
handle is turned, the greater the flow of water.
Temperature Control
The front part of the handle is the temperature control.
Turn it clockwise to make the water cooler. Turn it
anti-clockwise to make the water warmer (fig. 3).
When turning the handle anti-clockwise, it will stop
when the water is 40°C. To obtain water warmer
than 40°C, press inward on the temperature control,
and continue turning anti-clockwise (fig. 4).
Thermostat
The valve automatically adjusts for changes in
flow supply and maintains the outlet set water
temperature.

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 the
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.
