Important Safety Information
• Please read these instructions thoroughly and retain for future use.
• All products manufactured and supplied by Heritage are safe provided they are installed,
used correctly and receive regular maintenance in accordance with these instructions.
• If you are in any doubt about your ability to install this product safely you must
employ the services of an experienced qualified plumber.
• Do not use if the showerhead or shower hose has been damaged or is blocked.
• Do not crush or kink the shower hose, this could damage the hose and cause leaks.
• Remove all packaging and check the components for damage before starting
installation.
•
Warning: Before starting any installation please consider the following: Prior to
drilling into walls, check that there are no hidden electrical wires, cables or water
supply pipes. This can be checked with the aid of an electronic detector.
• If power tools are used do not forget to: - Wear eye protection
- Unplug equipment after use
•
The fitting of isolating valves is required as close as is practical to the supply inlet feeds of the
thermostatic mixing valve.
•
Warning: Before installing the new shower valve it is essential that you thoroughly flush
through the pipework in order to remove any remaining swarf, solder, etc.
Failure to carry out this procedure could cause problems or damage to
the workings of the shower valve.
• This product must not be modified in any way as this will invalidate the guarantee.

General Information
This product has been tested to comply with the BS EN 1287:1999 (LP) and BS EN
1111:1999 (HP) thermostatic mixing valve standards.
BS6700 recommends the temperature of stored water should never exceed 65ºC. A
stored water temperature of 60ºC is considered sufficient to meet all normal
requirements and will minimise the build up of lime scale in hard water areas (see Map
of Hard Water Regions in England & Wales on page 23).
If the fitting is installed at low pressure (tank fed), then the minimum distance from the
highest installed position of the showerhead to the underside of the cold tank should be
at least 1 metre to ensure adequate performance.
Note: Nominally equal (balanced) inlet supply pressures are recommended for optimum
performance with mixer showers.
This shower valve should be installed in compliance with the Water Supply (Water
Fittings) Regulations 1999 and the Scottish Byelaws 2004.

you have any doubts about the water
regulation requirements contact your local
water services provider or use the services of
a professional plumber.
This shower valve is suitable for use with the
following water supply systems.
• Gravity Fed Hot and Cold
(pressure Balanced)
• Gravity Fed Hot and Mains Cold
(differential pressure – see Specification
section on page 6.
• Instantaneous Water Heater
(combination boiler)
• Unvented System
• Pumped System
Gravity Fed Hot and Cold
Important: If you install this shower
valve with a gravity fed system, there must be
a minimum head (vertical distance) from the
underside of the cold water storage tank to
the showerhead position of at least 1 metre.
Note: Pumped system (with Essex
flange) If you install this shower valve to a
pumped gravity fed system where the
minimum head (vertical distance) from the
underside of the cold water storage tank to
the top of the hot water cylinder is less than 1
metre we recommend an Essex flange is used
as shown on page 11.
Flushing Pipework
Important: Before connecting the
shower valve (see Installation on pages 17-18),
supply pipework must be flushed to clear
debris before connecting the shower valve.
Debris will reduce the performance and life of
the shower.

the conditions of use are appropriate for the
valve.
Recommended Outlet temperatures
We recommend the following set maximum
mixed water outlet temperatures for use in all
premises:
41ºC for showers;
Warning: It is not a safe bathing
temperature for adults or children.
The British Burns Association recommends 37
to 37.5ºC as a comfortable bathing
temperature for children. In premises covered
by the Care Standards Act 2000, the maximum
mixed water outlet temperature is 43ºC.
The thermostatic mixing valve (TMV) will be
installed in such a position that maintenance of
the TMV and its valves and the commissioning
and testing of the TMV can be undertaken.
The fitting of isolation valves is required as
close as is practical to the water supply inlets
of the thermostatic mixing valve.
The mixed water temperatures must
never exceed 46ºC.
The maximum mixed water temperature can
be 2ºC above the recommended maximum set
outlet temperatures.
Note: 46ºC is the maximum mixed water
temperature from the bath tap. The maximum
temperature takes account of the allowable
temperature tolerances inherent in
thermostatic mixing valves and temperature
losses in metal baths.

Important: It is a requirement of Instantaneous Electric Heaters that a stable flow
of water passes through the heater. This requirement can be satisfied by using a ‘flow
stabiliser’ fitted prior to the heater and should be adjusted to give a temperature of
between 45 – 50C from the heater.
Flow regulators are factory fitted.

Commissioning
Commissioning notes for Thermostatic
Mixing Valves
The first step in commissioning a
thermostatic mixing valve is to check
the following:
1. The designation of the thermostatic
mixing valve matches the intended
application.
2. The supply pressures are within the
valves operating range.
If there is no significant change to the set
outlet temperature (+/-2ºC or less change
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 that
2ºC above the designated maximum mixed
water outlet temperature setting of the valve.
3. The supply temperatures are within the
valves operating range.
Temperature readings should be taken at the
normal flow rate after allowing for the system
to stabilise.
4. Isolating valves (and strainers preferred)
are provided.
The sensing part of the thermometer probe
must be fully submerged in the water that is to
be tested.
If all these conditions are met, proceed to
set the temperature as stipulated in the
maintenance section.
The mixed water temperature at the
terminal fitting must never exceed 46ºC.
It is a requirement that all 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:
•
Measure the mixed water temperature at
the outlet.
•
Carry out the cold water supply isolation
test by isolating the cold water supply to
the TMV wait for five seconds, if water is
still flowing check that the temperature is
below 46ºC.
17
Any TMV that has been adjusted or serviced
must be re-commissioned and re-tested in
accordance with the instructions in the
maintenance section.
The installation of thermostatic mixing valves
must comply with the requirements of the
Water Supply (Water Fittings) Regulations
1999.
Maintenance
General Cleaning
Your fitting has a high quality finish and should be treated with care to preserve the visible
surfaces. All surfaces will wear if not cleaned correctly. The only safe way to clean your mixer is
to wipe with a soft damp cloth. Stains can be removed using washing up liquid. All bath cleaning
powders and liquids will damage the surface of your fitting, even the non-scratch cleaners.
Note: Never use abrasive detergents or disinfectants or those containing alcohol,
hydrochloric acid or phosphoric acid.
To ensure continued performance of your shower the showerhead needs to be regularly
descaled.
Cartridge Maintenance
We advise that the shower valve is regularly serviced in hard water areas to maintain the flow of
water (see map of Hard Water Regions on page 23).
Isolate both hot and cold water supplies to the shower valve by either:
• Turning the water supply off at the mains stopcock or
• Turning off the isolation valves to the shower valve
1. Remove the handle: Unscrew the lever, loosen the grub screw using the hexagonal key and
carefully pull the handle off.
2. Unscrew the cartridge anti-clockwise (using a suitable spanner) and remove from the valve
body.
3. Carefully remove the cartridge assembly and spring. Remove all visible ‘O’ rings and washers
from the body.
4. Place the cartridge in a bowl and carefully add hot water (just off the boil) and vinegar to descale the cartridge. Leave in the solution until the water has cooled and rinse with clean
water.
5. Replace all seals and grease with a silicon grease supplied by Heritage and carefully refit.
6. Reset the maximum temperature and refit the handle and tighten the grub screw. Screw the
lever back into the handle.

Maintenance Cont.
Adjusting the Temperature
The shower valve has been factory set
with equal (balanced) hot and cold water
supply pressures with the hot water
supply at 65ºC.
If your operating conditions are different
from those above, the outlet water
temperature may differ from the factory
setting.
If required the shower valve can be recalibrated to suit your own temperature
requirements.
Set the temperature control lever to
maximum and check the temperature of
the water with a thermometer. If the
temperature is not correct, re-calibrate
the shower valve.
1. Turn the temperature handle anticlockwise to the maximum temperature
position.
hexagonal key and carefully pull the
temperature handle and shroud off.
3. Push the temperature handle back
onto the cartridge spidle and turn to
increase / decrease the temperature.
• Turn clockwise for a cooler
temperature
• Turn anti-clockwise
for a warmer temperature
Note: This will be the maximum
temperature setting, it is recommended
that the temperature is set no higher
than 43ºC.
4. Once the correct temperature is
achieved, remove the temperature
handle, push the shroud and handle back
on. Tighten the grub screw and re-fit the
indice.
