User Guide.
Note! Only use Shower Fittings recommended
by the manufacturer or supplier.
Suitable Plumbing Systems
Gravity Fed:
The thermostatic mixer must be fed from a cold
water cistern (usually located in the loft space) and
a hot water cylinder (usually located in the airing
cupboard) providing nominally equal pressures.
Mains Pressurised Instantaneous Hot Water
System (Combination Boiler):
The thermostatic mixer can be installed with
systems of this type with balanced pressures.
(Recommended Minimum Maintained Pressure:
1.0 Bar).
Note! On combination boiler systems we
recommend that the thermostatic mixer is
operated in the maximum flow position in order to
achieve the minimum flow rate required to ignite
and run the boiler.
Unvented Mains Pressure System:
The thermostatic mixer can be installed with an
unvented, stored hot water system.
Pumped System:
The thermostatic mixer can be installed with an
inlet pump (twin impeller). The pump must be
installed in a suitable location and in accordance
with its instructions.

temperature, or clockwise to decrease the
temperature (¼ turn = approximately 1°C).
7. Once the desired maximum blend temperature
has been achieved turn off the mixer by
rotating either the hub or flow control lever
(depending on model) fully clockwise.
Note! Do not remove the hub.
8. Refit the hub retaining screw.
9. Refit the control lever with the lever at the top

10.C heck that the shower temperature is
correct.
Before using the shower the maximum temperature
must be checked to make sure that it is at a
safe level. It has been preset to approximately
41°C at the factory but due to variations in site
conditions the maximum temperature may need
adjustment.
Note! Make sure that the hot water temperature
is at least 55°C and that there is sufficient supply.
For Type 2 installations the maximum blend
temperature is determined by the application,
refer to section: ‘Type 2 Valves - Application’.
1. Turn on the mixer to the maximum temperature
and maximum flow (i.e. fully anticlockwise) and
allow the temperature to stabilise.
If the temperature is too hot or too cold adjust
as follows.
2. Carefully remove the concealing cap from the

Important! For TMV2 installations the mixed water temperature at the discharge point should never
exceed 46°C.
In order to achieve the safe water temperatures expected of a Type 2 Valve it is essential that the valve
is used only for the applications covered by its approved designations, with the appropriate water supply
pressures and temperatures, and it is commissioned, maintained and serviced in accordance with the
recommendations contained in this guide (refer to the section ‘Maintenance, In-Service Tests’ for in
service test frequency that must be used as a minimum guide in Type 2 installations).
Supply Conditions
For applications where a Type 2 Valve is required, the supply conditions must comply with the values
extracted from the TMV2 standard (EN1287 & EN1111), shown in the Table below. Note that both hot
and cold supply pressures must lie within the same pressure range.

Recommended Outlet Temperatures
The fitting of strainers is recommended as close
as is practicable to the water supply inlets of the
thermostatic mixing valve.
The BuildCert TMV scheme recommends the
following set maximum mixed water outlet
temperatures for use in all premises:
If all of these conditions are met, proceed to
set the temperature as specified in section:
‘Commissioning’ .
44°C for bath fill, but see notes below;
41°C for showers;
41°C for washbasins;
38°C for bidets.
It is a requirement that all TMV2 approved
valves shall be verified against the original
set temperature results once a year. When
commissioning/testing is due the following
performance checks shall be carried out.
Important! For TMV2 installations the mixed
water temperature at the discharge point should
never exceed 46°C.
Measure the mixed water temperature at the
outlet.
The maximum mixed water temperature can
be 2°C above the recommended maximum set
outlet temperatures.
Carry out the cold water supply isolation test by
isolating the cold water to the TMV, wait for five
seconds if water is still flowing check that the
temperature is below 46°C.
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.
If there is no significant change to the set outlet
temperature (±2°C or less change from the
original settings) and the fail-safe shut off is
functioning, then the valve is working correctly
and no further service work is required.
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.
Notes! If there is a residual flow during the
commissioning of the valve 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.
Commissioning notes for Thermostatic Mixing
Valves
Temperature readings should be taken at the
normal flow rate after allowing for the system to
stabilise.
The first step in commissioning a thermostatic
mixing valve is to check the following:
The designation of the thermostatic mixing
valve matches the application, refer to section:
Type 2 Valves, Application.
The sensing part of the thermometer probe
must be fully submerged in the water that is to
be tested.
The supply pressures are within the valves
operating range.
The supply temperatures are within the valves
operating value.
Any TMV that has been adjusted or serviced
must be re-commissioned and re-tested in
accordance with the instructions given in this
guide.
The fitting of isolation valves is required as
close as practicable to the water supply inlets of
the thermostatic mixing valve.
The installation of thermostatic mixing valves
must comply with the requirements of the Water
Supply (Water Fittings) Regulations 1999.
