Safety and Important Information
Hansgrohe products are safe provided they are installed, used and maintained in
accordance with these instructions and recornrnendations.
Please read these instructions thoroughly and retain for future use.
The plumbing installation of this thermostat mixing valvemust comply with the require-
ments of UK
Water Regulations/Bylaws (Scotland), Building Regulations or any other regulations
specified by the local Water Authority and supplier.
The installation of thermostatic mixing valves must comply with the requirements of the
Water Supply (Water Fittings) Regulations 1999.
We strongly recommend that you use a plumber registered with or a member of an
Association:
Chartered Institute of Plumbing and Heating Engineering (CIPHE)
Water Industry Approved Plumber Scheme (WIAPS)
Dispose of plastic bags carefully
Keep children well away from the work area.
Check for hidden pipes and cables in the wall before drilling holes.
The unit must be mounted on a finished waterproofed wall surface (usually tiles).
If you are using power tools (e.g. to drill holes) wear safety glasses and always discon-
nect tools from the power supply after use.
Do not operate the shower unit if the hand shower or spray hose has been damaged
or is blocked.
Do not block the flow of water from the hand shower, by placing it on your hand or
any other part of your body or foreign object.
The valve must remain accessible to maintain and commission it.
The thermostatic unit should be serviced annually by a qualified person to ensure
maximum safety during use.
The thermostatic mixing valve will be installed in such a position that maintenance of the
TMV and its valves and the commissioning and testing of the TMV can be undertaken.
The mixer is fitted with check valves (page 35 pos. 96737000). There are filters on
the thermostatic element too (page 35 pos. 96922000 and A).
The fitting of isolation valves is required (preferred location page 38 Installation
Requirements)
Technical Data
This thermostatic valve will suit supplies of:
HIGH PRESSURE (HP-S / HP-T)
Operating pressure:
max. 10 bar
Recommended operating pressure:
1 - 5 bar

16 bar
Hot water temperature:
max. 80°C
Recommended hot water temp.:
65°C
Rate of flow from bath spout:
20 l/min. @ 3 bar
Rate of flow from shower outlet:

Hot and cold supply pressure should be balanced
Mixed water temperature
Application
Mixed water temperature
(at point of discharge).
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 32.
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 or TMV3 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.
The mixed water temperatures must never exceed 46°C.
The maximum mixed water temperature can be 2°C above the recommended maxi-
mum set outlet temperatures.
Note:
46°C is the maximum mixed water temperature from the bath tap. The maxi-
mum 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
