Removing Spout
The HTMWMRS wall mounted and HTMDMRS deck mounted taps have a removable spout to
assist with cleaning, disinfection by immersion or sterilisation in an autoclave.
Inta recommend that a replacement spout is available as the tap should not be left without
a spout (HTMSP16XX).
Cleaning, disinfection and sterilisation is only necessary if there is evidence of solid deposits
around the outlet from the tap or a minimum of once per year.
• Ensure the isolation valve in both supplies to the tap are in the closed position and the lever is
also in the closed position to prevent water flow and potential flooding.

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.

Wash Hand Basin 41˚C
Installation
10. It is essential that this product should not be installed in situations where there is a possibility of
the valve being deprived of water or where demands for water are greater than the actual
stored supplies.
11. To ensure that the performance levels of this Thermostatic Mixing Valve are maintained (in the
event of cold water failure) the temperature of the hot water supply at the point of entry to the
valve must be a minimum of 10°C above the commissioned mixed water discharge
temperature.
12. This Thermostatic Mixing Valve must not be subject to any extreme temperature variations
either during the installation or under normal operating condition
Commissioning
IMPORTANT – The following instructions must be read and understood prior to the commissioning
of a Thermostatic Mixer. If under any circumstances there are aspects to the installation/system which
do not comply with the specification laid down, the valve MUST NOT is put into operation until the
system/installation complies with our specification.
1. Ensure that the system is thoroughly cleaned and free from any debris prior to the
commissioning of the valve. (See page 10)
2. The commissioning of the temperature must be carried out using a suitably calibrated
thermometer – preferably a digital thermometer. (See page 8)
3. In the absence of other temperatures being specified we recommend that the outlet
temperatures quoted in table 1 are used, extracted from the “National Health Service –
Health Guidance Note – Safe Hot Water and Surface Temperatures”.
Table 1
4. Each valve must be commissioned taking into consideration any fluctuations, which may
occur within the system due to simultaneous demands. It is advisable that any outlets which
are connected to the same supply as the mixing valve are opened during setting of the
mixed water temperature. It is advisable to ensure that the water temperatures are
established before any attempt to commission.
5. Once the supply temperatures are stable and the normal operating conditions are
established, the valve can be commissioned. We suggest that the following sequence is
followed when commissioning the valve:
5.1 Using the lever turn to the maximum hot setting of the tap, the mixed water temperature
should be preset (see page 8).
5.2 Measure and record the temperature of the hot and cold water supplies at the
connections to the valve.

Application Maximum Hot Water Temperature
Wash Hand Basin 43˚C
Table 2
Commissioning
5.3 Measure and record the temperature of the water discharging from the valve for the
largest and smallest draw off point.
5.4 Isolate the cold water supply to the valve and monitor the mixed water temperature.
5.5 Measure and record the maximum mixed water temperature and the final temperature.
The final temperature found during the test should not exceed the values quoted in
table 2.
5.6 Record all the equipment used during the commissioning.
6. Ensure that the application, to which the valve will be used, is appropriate for the approved
designation.
7. The above information must be recorded and updated on every occasion when any work is
carried out on the valve.
In Service Testing
To ensure that the Thermostatic Mixer maintains a high level of protection, we advise the following in
service testing is followed (the same equipment used to commission the valve initially must be used in
the following tasks).
1. After a period of between 6 and 8 weeks after commissioning carry out the following.
a) Record the temperature of the hot and cold water supplies.
b) Record the temperature of the mixed water at the largest draw off flow rate.
c) Record the temperature of the mixed water at the smallest draw off flow rate.
2. If the mixed water temperature has changed significantly from the previous test results
(e.g. > 1 k), record the change and before re-setting the mixed water temperature check that:
a) All the strainers are clean
b) All the check valves are in good working order
c) The isolation valves are fully open.
