Unvented Mains Pressure System
The drawing shows a typical installation of a bath filler in conjunction with an unvented hot
water system. This type of installation must be carried out in accordance with Part G of the
Building Regulations.
Whilst pressures are theoretically equal (balanced) most unvented hot systems have a pressure
reducing valve on the incoming cold water prior to the hot water storage vessel. This means
that the hot and cold pressures can be significantly different.
Most unvented systems use an inlet manifold located directly after the pressure reducing valve.
It is recommended that the cold supply be taken from one of the outlets of the manifold directly
to the bath filler as an independent supply.
For systems without a manifold unit after
the pressure reducing valve and where
the cold water supply pressure is
significantly higher than the hot supply we
recommend that a separate pressure reducing
valve is fitted to the cold supply, as close as
possible to the bath filler and with no draw off
points between it and the bath filler.
Flow regulators are required for
installations where a PRV is not fitted to
ensure simultaneous demand is
accounted for.

Pumped Systems
Pumped systems use a booster pump to increase the pressure of the gravity fed water supplies.
These booster pumps are used where the head of water is insufficient to provide a satisfactory
bath fill or where a high performance bath fill is
required.
Please ensure that the performance of the pump
is matched to suit the bath filler.
Follow the instructions for gravity fed installations
taking into account the installation requirements
of the pump.
Ensure that the hot and cold water storage
capacity is sufficient to supply the bath filler and
any other draw off points that may be used
simultaneously.
Most pumps require a minimum head of water to
allow the flow switches to operate automatically.
Where this is not available a negative head
kit may be required to operate the pump.
Pumps
Please consult the pump manufacturer’s
installation requirements.
Cold Supply
direct from mains
Modulating Combi Boiler / Instantaneous Gas Water Heater
The drawing shows a typical installation of a bath filler in conjunction with a combination
boiler.
Combi boilers will produce a constant flow of water
at a temperature within its operating range.
However we recommend that the system should
supply hot water in excess of 60˚C.
The hot water flow rates are dependant upon the
type of boiler / heater used and the temperature
rise required to heat the cold water to the required
temperature.
The cold water flow rates may be much greater as
they are generally unrestricted from the mains cold
water supply. To ensure relatively balanced flow
rates, we recommend that a pressure reducing
valve or 6 l/min flow regulator is fitted in the cold
water supply pipe.

Gravity System
The drawing shows a typical installation of a bath filler on a gravity supplied system.
The cold water supply must be connected
directly to the water cistern. The hot water
supply should be connected to the hot water
cylinder via an Essex flange or Sussex flange or
to the vent or a draw off pipe as close as
possible to the top of the cylinder.
For equal tank fed pressures there is no need to
fit the flow regulators. This installation is the
recommended minimum for gravity supplies. For
systems with less than 2 metre head pressure,
we recommend that a suitable booster pump is
fitted to increase the supply pressure.

Mini. 2m head
Please note the minimum head pressure required to ensure operation of the valve. In
accordance with good plumbing practice, we recommend that a totally independent hot and
cold water supply be taken to the valve.
Cold Mains & Gravity Hot Supplies
If the cold supply to the bath filler is direct from
the cold water mains and the hot water supply
is gravity fed from the cold water cistern via the
hot water cistern you MUST fit a pressure
reducing valve or a 6 l/min flow regulator.
Site Preparation
It is important to plan the installation thoroughly to suit site conditions before
commencing.
• Before commencing the installation ensure site conditions are suitable.
• The bath filler is designed for concealed pipework, whether in a solid or studded wall.
• The thickness of wall tiles, plaster or plaster board should all be considered when routing the
hot and cold supply pipes.
• The valve requires the offset connectors to have 150mm centres and sufficient thread must
protrude from the finished tiled surface to allow the concealing plates to be fitted and the
union nuts to be fully tightened.
• Ensure the bath filler will be horizontal when installed.
• The supply pipes can come from below, above, the side or through the wall.

Site Preparation
• The supply pipes and offset connectors must be firm and secure to support the bath filler.
If not embedded into the wall with plaster the pipes should be fixed securely to the studding
or by using a mounting plate (not supplied).
• Angle tap swivel connectors or compression/solder fittings can be used to connect the pipes
(not supplied).
• The whole system should be thoroughly flushed, prior to the connection of the hot and cold
water supplies to the bath filler, to remove any debris that may be in the supply pipework.
• Ensure there are no joint leaks before finishing the wall.
• Isolation valves must be fitted in an accessible position to both the hot and cold supplies
should the valve need to be isolated in the future for servicing.

Calibration
Inta Ion and Telo bath fillers have a factory set outlet temperature of 38˚C via the security setting.
This is based on a balanced supply pressure and a stable hot water inlet temperature of 65˚C.
However, the calibration point MUST be checked and re-set as necessary to suit site conditions.
Care must be taken when re-calibrating the valve as INCORRECT CALIBRATION CAN CAUSE
INJURY.
• Remove the cover (2), retaining screw (3) and temperature control knob (4) by pulling away
from the bath filler and the temperature stop ring (5).
• Fully open the flow control (1) and allow the outlet temperature to stabilise.
• Temporarily refit the control knob (4) and using a digital thermometer it is possible to increase
or reduce the mixed water outlet temperature until 38˚C is re-established, by slowly rotating
the control knob.
• Remove the control knob (4) and refit the temperature stop ring (5) onto the splined section of
the cartridge. The red dot on the temperature stop ring must align with the temperature position
symbol (7) on the valve body.
• Refit the temperature control knob in the reverse order ensuring that 38˚C on the control knob
is in line with the temperature position symbol (7).
PLEASE NOTE THAT ONCE CALIBRATED, THE SECURITY SETTING WILL ONLY BE 38˚C
UNDER THE SUPPLY CONDITIONS USED FOR CALIBRATION.

Recommended Outlet temperatures
The BuildCert TMV scheme recommends the following set maximum mixed water outlet
temperature for use in all premises:
Application
Recommended Hot Water Temperature
Bath Fill
44˚C
The mixed water temperature must never exceed 46˚C.
The maximum mixed water temperature can be 2˚C above the recommended maximum set
outlet temperature.
Note: 46˚C is the maximum mixed water temperature from a bath filler. The maximum
temperature takes account of the allowable tolerances inherent in thermostatic bath fillers
and temperature loss in metal baths.
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
bath filler valve. The installer of the thermostatic bath filler 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 bath filler 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 bath filler 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 bath filler.

Installation
3. The supply to which the thermostatic bath filler is to be installed must be thoroughly flushed
and cleaned to remove any debris, which may have accumulated during the installation.
Failure to remove any debris will affect the performance and the manufacturer’s warranty of
the product. In areas that are subject to aggressive water, provision must be made to treat
the supplies prior to the supplies entering the bath filler.
4. The thermostatic bath filler has been designed for horizontal installation and surface
mounting.
5. The thermostatic bath filler will be installed in such a position that maintenance of it’s
components, associated valves and the commissioning and testing of the bath filler can be
undertaken.
6. The hot and cold water supplies must be connected to the valve strictly in accordance with
the indications on the body of the valve i.e. hot water supply to the hot port of the valve.
7. In a situation where one or both of the water supplies are excessive, it is recommended to fit
a Pressure Reducing Valve to reduce the pressure(s) to within the limits as quoted previously.
8. Any thermostatic bath filler must be fitted with a back flow prevention device, such as check
valves to prevent the cross contamination of supplies. The thermostatic bath filler is supplied
complete with integral insert check valves and strainers.
9. Isolation valves in an accessible position are required as close as is practicable to the water
supply inlets of the thermostatic bath filler.
10. The fitting of strainers is recommended as close as is practicable to the water supply inlets of
the thermostatic bath filler.
11. It is essential that the fail safe thermostatic bath filler 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.
12. To ensure that the performance levels of the thermostatic bath filler are maintained (in the
event of cold water failure), the temperature of the hot water supply at the point of entry to
the thermostatic bath filler must be a minimum of 10˚C above the commissioned mixed
water discharge temperature.
13. The fail-safe thermostatic bath filler must not be subject to any extreme temperature
variations either during the installation or under normal operating conditions.
Commissioning
Important: - The following instructions must be read and understood prior to commissioning the
thermostatic bath filler. If under any circumstances there are aspects to the installation / system
which do not comply with the specification laid down, the valve MUST NOT be put
into operation until the system / installation complies with the specification. However if all
these conditions are met, proceed to set the temperature as follows;
1. Ensure that the system is thoroughly cleaned and free from any debris prior to
commissioning the thermostatic bath filler.
© Intatec Ltd 2011
14
Commissioning
2. Commissioning the temperatures must be carried out using a suitably calibrated
thermometer, preferably a digital thermometer. The sensing part of the thermometer probe
must be fully submerged in the water when testing.
3. The 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 bath filler are open during setting of the mixed
water temperature. It is advisable to ensure that the water temperatures are established
before any attempt to commission.
4. Once the supply temperatures are stable and the normal operating conditions are
established, the bath filler can be commissioned. The following sequence should be followed
when commissioning the valve;
4.1 The first step in commissioning a thermostatic bath filler is to check the following:
• The designation of the thermostatic bath filler matches the application.
• The supply pressures are within the valve’s operating range.
• The supply temperatures are within the valve’s operating range.
• Isolating valves (and ‘Y’ strainers preferred) are provided.
4.2 If all these conditions are met, proceed to set the temperature following the procedure
described earlier in the Calibration section.
4.3 Measure and record the temperature of the hot and cold water supplies at the
connection to the valve.
4.4 Measure and record the temperature of the water discharging from the valve.
4.5 Isolate the cold water supply to the valve and monitor the mixed water temperature.
4.6 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.
4.7 Record all the equipment used during the commissioning.
4.8 The mixed water temperature at the terminal fitting must never exceed 2˚C above the
set temperature.
5. If the mixed water temperature exceeds the recommended temperature of 41˚C by 2˚C or
does not reach 41˚C the bath filler can be adjusted as follows:
5.1 With stable supply conditions remove the temperature control knob.
5.2 Rotate the temperature control knob by one spline clockwise to increase the temperature
and one spline anticlockwise to reduce it.
5.3 Measure the water discharging from the shower.
5.4 Repeat 5.2 until the desired temperature is stabilised and record the temperature.
5.5 Repeat 4.4 and 4.5
© Intatec Ltd 2011
15
Commissioning
5.6 Secure the temperature control knob with the retaining screw and re-fit the cover.
6. The above information must be recorded and updated on every occasion when any work is
carried out on the valve.
In Service Testing
It is a requirement that all TMV2 approved valves shall be verified against the original set
temperature results once a year. When commissioning / testing is due the following
performance checks shall be carried out.
1. Measure the mixed water temperature at the outlet.
2. Carry out the cold water supply isolation test by isolating the cold water supply, wait for five
seconds if water is still flowing check that the temperature is below 43˚C.
3. If there is no significant change to the set outlet temperature (±2˚C or less from the original
settings) and the fail-safe shut off is functioning, then the valve is working correctly and no
further service work is required.
Notes:
• If there is a residual flow during the commissioning or the annual verification (cold water
supply isolation test), then this is acceptable providing the temperature of the water seeping
from the valve is no more than 2˚C above the designated maximum mixed water outlet
temperature setting of the valve.
• Temperature readings should be taken at the normal flow rate after allowing for the system
to stabilise.
• The sensing part of the thermometer probe must be fully submerged in the water to be
tested.
• Any thermostatic bath filler that has been adjusted or serviced must be re-commissioned
and re-tested in accordance with the manufacturers’ instructions.
