Application
The thermostatic mixing shower valve has been independently tested by WRAS and certified as meeting
the requirements of the BS EN 1111:1999 under the TMV2 Scheme as being suitable for use on the
following designations.
Recommended Outlet Temperatures
The BuildCert TMV scheme recommends the following set maximum mixed water out let temperatures for
use in all premises:
The mixed water temperature must never exceed 43˚C.
The maximum mixed water temperature can be 2˚C above the recommended maximum set outlet
temperature.
Recommended Outlet Temperatures
Note: 43˚C is the maximum mixed water temperature from the shower. The maximum temperature takes
account of the allowable tolerances inherent in thermostatic shower valves and temperature losses.
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 Standard Act 2000, the maximum mixed water outlet
temperature is 43˚C.
Installation
Important: - The following instructions must be read prior to the installation of the thermostatic shower
valve. The installer of the thermostatic shower valve must comply with the requirements of the Water supply
(Water Fittings) Regulations 1999 and also be aware of their responsibility and duty of care to ensure that
all aspects of the installation comply with the regulations.
It has been brought to our attention that flushing water systems using certain chemicals may wholly or
partially remove the lubricant from the internal workings of the valve, which may adversely affect its
performance. We recommend that following flushing the system with chemicals; valves are checked for
correct operation.
1. It is essential that before installing any thermostatic shower valve to ensure that the supply conditions of
the system to which the valve is intended to be fitted are checked to confirm compliance with the
parameters as quoted within the technical specification and conditions on which the approval is
granted i.e. verify supply temperatures, supply pressures, risk assessment.
2. Consideration must be made for the possibility of multiple / simultaneous demands being made on the
supply system whilst the thermostatic shower valve is in use, all practical precautions must be made to
ensure that the valve is not affected. Failure to make provision within the pipe sizing etc. will affect the
performance of the shower valve.
