IMPORTANT – The following instructions must be read prior to the installation of any thermostatic
mixing valve.
The installer should also be aware of his responsibility and duty of care to ensure that all aspects
of the installation comply with all current regulations and legislations.
It has been brought to our attention that flushing water systems using certain chemicals may affect
the workings of the valve, which may adversely affect its performance.
We recommend that following system flushing with chemicals, mixers are checked for correct
operation.

system to which the valve is intended to be fitted are checked to confirm compliance with the
parameters as quoted within the Technical Specification above and conditions on which the
approval is granted i.e. verify supply temperatures, supply pressures, risk assessments etc.
