Installation
IMPORTANT – The following instructions must be read prior to the installation of any Inta
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.
1. It is essential that, before installing a thermostatic mixing valve, 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 above and conditions on which the
approval is granted i.e. verify supply temperatures, supply pressures, risk assessments etc
2. Consideration must be made for the possibility of multiple/ simultaneous demands being made
on the supply system whilst the thermostatic mixing valve is in use, all practical pre-cautions
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 valve.
3. The supply system to which the Thermostatic Mixing Valve is to be installed into must be
thoroughly flushed and cleaned to remove any debris (see page 13), which may be
accumulated during the installation. Failure to remove any debris will affect the performance
and the manufacturer’s warranty on the product.
4. Independent filters/check valves and isolation valves must be fitted in conjunction with the
valve. In areas that are subject to hard water, provision must be made to treat the supplies
prior the supplies entering any product.
5. The maximum flow rate of the valve will only be achieved when the supply conditions are
achieved as quoted, with a flow condition under 1 bar differential pressure.
6. This Inta thermostatic mixer has been designed to be wall mounted. It is essential that access to
the valve is not obstructed for future maintenance, that may be required to the valve or
associated fittings.
7. The connection of the hot and cold supplies must be in accordance with the instructions shown
on page 8 i.e. hot water connected to the left hand side of the valve when the nozzle is facing
you.
8. In a situation where one or both of the water supplies are excessive, it is recommended to fit a
Pressure Reducing Valve, WRAS approved product, to reduce the pressure(s) to within those
stated in the Technical Specification previously stated or a suitable flow regulator.
9. We recommend that Y pattern strainers and full bore isolation valves are installed in
conjunction with this product as close as practically possible to the location valve.
