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:
Institute of Plumbing (IOP) - throughout the UK
National Association of Plumbing, Heating and Mechanical Services Contractors
(NAPH & MSC) - England & Wales
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 fitting of isolation valves is required (prefered location page: 6 and 7; Installation Requirements). The
mixer incorporates check valves (page 15 pos. 8) and filters on the thermostatic element (page 15 pos 7).

Technical Data
Ecostat ibox
This thermostatic valve will suit supplies of:
HIGH PRESSURE (HP-S)
Operating pressure: max. 10 bar
Recommended operating pressure: 0.2 - 5 bar
Test pressure: 16 bar
Hot water temperature: max. 80°C
Recommended hot water temp.: 65°C
Rate of flow: 58 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 10 „Commisioning“.
NB. If a water supply is fed by gravity then the
supply pressure should be verified to ensure the con-
ditions 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 follow-
ing 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 tempera-
ture from the bath tap. The maximum temperature
takes account of the allowable temperature toler-
ances 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 Stand-
ards Act 2000, the maximum mixed water outlet
temperature is 43°C.
Supply Conditions TMV2
Operating pressure range High pressure
Maximum static pressure - bar 10
Flow pressure, hot and cold - bar 1 to 5
Hot supply temperature - °C 55 to 65
Cold supply temperature - °C 5 to 25

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:
Gravity Fed Hot and Cold (pressure balanced) 0.1 - 1.0 bar
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 1 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.
