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 requirements 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 disconnect 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 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 17
#94074000). There are filters on the thermostatic
element too (page 17 #94282000).

The fitting of isolation valves is required (preferred
location page 6 and 7 Installation Requirements)

Technical Data

This thermostatic valve will suit supplies of:
HIGH PRESSURE (HP-S-T)

Operating pressure: max. 10 bar
Recommended operating pressure: 1 - 5 bar
Test pressure: 16 bar
Hot water temperature: max. 70°C
Recommended hot water temp.: 65°C
Rate of flow: 36 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).
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
14 „Commisioning“.
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 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,
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 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.
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

Installation Requirements

This thermostatic mixer valve must be installed in
compliance with current Water Regulations. If you have
any doubts about the Water Regulation requirements
contact your local water services provider or use the
services of a professional plumber.

This mixer valve is suitable for use with the following
water supply systems:

Gas Combination Boiler (multi-point) 1.0 - 10 bar*

Unvented System (pressure balanced) 1.0 - 10 bar

Pumped System 1.0 - 10 bar

IMPORTANT: If you install this mixer with a gravity
fed system, there must be a minimum head (vertical
distance) from the underside of tlie cold water storage
tank to the showerhead position of at least 5 metre.

Before connecting the mixer, water should be flushed
through the system to remove all debris that might
otherwise damage the valve.

* If pressure is in excess of 3.5 bar, a pressure-reducing
valve should be fitted.
