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 mixer is fitted with check valves (page 38 pos. 95773000). There are filters on
the thermostatic element too (page 38 pos. 98282000).
The fitting of isolation valves is required (preferred location page 41 Installation
Requirements)
Technical Data

Recommended operating pressure: 1 - 5 bar
Test pressure: 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: 18 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).
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 33.
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
