Introduction
A thermostatic mixing valve (TMV) is used in domestic hot water systems.
It’s function is to maintain the temperature of the mixed water, supplied to the user, constant at
the set value when there are variations in the supply pressure and temperature of the incoming
hot and cold water or in the flow rate.
The Intamix Pro TMV has been specifically designed for applications requiring a high volume of
water at multiple outlets, such as shower blocks and central mixing.
Systems of this nature require precise, stable temperature control, especially when there are
variations in the flow rates drawn off by the users.
It is recommended, especially in hard water areas, that a water softener such as the ActivFlo or
ActivFlo lite be fitted to reduce the risk of calcium deposits forming.

Installation
If the thermostatic mixing valve is not installed, commissioned and maintained properly,
according to the instructions contained in this manual, it may not operate correctly and may
endanger the user.
Before installation the system must be checked to ensure that it’s operating conditions are within
the range of the valve; eg the supply temperatures, pressures and flow rates.
Systems must be flushed to remove any dirt or debris, which may have accumulated during
installation, which may affect its performance and the manufacturer’s product guarantee.
Failure to remove dirt or debris may affect the performance and the manufacturer’s product
guarantee.
The installation of filters, of appropriate capacity, at the inlet from the mains supply is always
advisable.
In the case of highly aggressive water, arrangements must be made to treat the water
before it enters the thermostatic mixing valve, in accordance with current legislation.
Intamix Pro TMV must be installed strictly in accordance with the Water Supply (Water Fitting)
Regulations 1999, any local authority regulations and the diagrams in this manual.
They can be installed in any orientation, either vertically or horizontally.
The following are shown on the mixer body:
~ hot water inlet, denoted by the letter ‘H’.
~ cold water inlet, denoted by the letter ‘C’.
~ mixed water outlet, denoted by the letters ‘MIX’.

Installation Continued
It is essential that access to the valve is totally unobstructed for any maintenance which may be
required or to the connections.
The pipework to or from the valve must not be used to support the valve unless adequately
supported.
Commissioning
After installation, the valve must be tested and commissioned in accordance with the
instructions given below, taking into account current applicable standards and Codes of
Practice.
1. Ensure that the system is clean and free from any dirt or debris before commissioning.
2. It is recommended that the temperature is set using a suitable calibrated digital
thermometer. The valve is commissioned by measuring the temperature of the mixed water
emerging at the point of use.
3. The maximum discharge temperature from the valve must be set to take account of
fluctuations due to simultaneous use.
Allow conditions to stabilise before measuring the temperature and commissioning
4. Adjust the temperature using the adjusting knob on the valve.
Setting the Temperature
The temperature is set to the required value by means of
the adjusting knob with the graduated scale located at
the top of the valve.
1. Using a suitably sized screw driver unscrew the knob
retaining screw.
2. Note the position of the lug on the body and the
corresponding recess inside the knob.
3. Temporarily refit the knob onto the splined section of
the stem and rotate the stem to alter the mixed water
temperature.
To increase the temperature, rotate the spindle
anti-clockwise.
To decrease the temperature, rotate the spindle
clockwise.
4. Allow the outlet temperature to stabilize for 60
seconds and once again take a temperature
reading.
Repeat the procedure until the desired temperature has been reached.
5. Check the circulating water temperature is stable.

Preset Locking
Position the adjusting knob to the temperature required.
Unscrew the retaining screw.
Remove the knob by pulling away from the valve and reposition on the splined shaft so that the
internal slot locates on the position indicator on the knob frame.
Re fit and tighten the retaining screw.
Maintenance
In service, tests should be carried out regularly to monitor the TMV’s performance, as
deterioration could indicate that the valve and/or the system require maintenance.
If, during these tests, the temperature of the mixed water has changed significantly when
compared with the previous test, the details given in the Installation and Commissioning
sections should be checked and maintenance carried out.
The following should be checked regularly to ensure that the optimum performance levels of the
valve are maintained.
Every 12 months or more often if necessary.
1. Check and clean the system filters.
2. Check that any non-return valves positioned upstream of the TMV are operating correctly
and free from debris.
3. Limescale can be removed from internal components by immersion in a suitable
de-scaling fluid.
4. When the components have been checked and maintained, the mixed water outlet
temperature should be checked using a thermometer following the procedure detailed in
the Commissioning section.
Problem Solving
The following details are supplied for on site queries, should you require any further assistance
our Technical Department can be contacted directly on 01889 272 199.
1 Hot water at cold outlet
i. Operation of the in line check valves is hindered, check the valve is seated correctly.
ii. Check Valves not fitted.
iii. Unbalanced hot/cold supply pressure.
2 Fluctuating mixed water temperature
i. Erratic supply temperatures at the inlets of the valve.
ii. Starvation of the water supplied at the inlets of the valve.
iii. Incorrect commissioning of the valve.
