General Information
This product has been tested to the TMV2 scheme which complies with the BS EN
1287:1999 (LP) and BS EN 1111:1999 (HP) thermostatic mixing valve standards and
TMV3 scheme for use in Healthcare and commercial situations and performs to the
requirements of NHS specification D08.
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.
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.

Installation Requirements
These fittings need to be installed in
accordance with the following Installation
Requirements and Notes (IRN) to ensure
they meet the requirements of the Water
Supply (Water Fittings) Regulations 1999
and the Scottish Byelaws 2004.
IRN R001: See text of entry for Installation
Requirements or Notes.
IRN R040 - Schedule 2-15 (1): The
fitting shall be installed so that its outlet
discharges above the spill-over level of
any fixed appliance as indicated below:-
For backflow protection in domestic or
installations up to, and including, Fluid
Category 3.
If the fitting cannot be installed as
indicated in the table opposite it shall be
installed as either a or bbelow:
a: with an approved double check valve
assembly or some other no less
effective backflow prevention device
immediately upstream of the inlet.
b: so that it draws water by gravity only
from a cistern, or cylinder having a
permanently open vent pipe, and the
distributing pipe supplies no other fitting
(other than draining tap) at a lower level.
For backflow protection in premises or
installations up to, and including Fluid
Category 5.
The vertical distance of the outlet above
the spill-over level shall be not less than

Conditions of use for Type 2 (Thermostatic mixer) valves
High Pressure Low Pressure
Maximum Static Pressure (Bar) 10 10
Flow Pressure, Hot & Cold (Bar) 0.5 to 5 0.1 to 1.0
Hot Supply Temperature (ºC) 55 to 65 55 to 65
Cold Supply Temperature (ºC) Equal to or less than 25 Equal to or less than 25
Note: Valves operating outside these
conditions cannot be guaranteed by the
Scheme to operate as Type 2 valves.
If a water supply is fed by gravity then the
supply pressure should be verified to ensure
the conditions of use are appropriate for the
valve.
Recommended Outlet temperatures
The BuildCert TMV scheme recommends
the following set maximum mixed water
outlet temperatures for use in all premises:
41ºC for showers;
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.
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 table on page 12 shows the flow regulator requirements and valve adjustments for
various hot / cold supplies.
# Flow regulators are fitted and will be required to be removed when installed in low
pressure (gravity fed) applications below 1.0 bar. To remove: unscrew the retaining ring
and remove regulator and washer. Re-fit elbows back to the body.
* With certain permutations of combi-boiler hot supply and cold supply, it must not be
necessary to fit the flow regulator on the hot supply.
** The bottom cap is factory set at 3/4 turn from
the fully closed position. Only adjust if instructed
to do so in the table on page 12 or when fitting a
replacement cartridge assembly. (See maintenance
section. Remove mixing valve from backplate (see
Installation). Peel of label to reveal bottom cap, with a
marker pen, mark a point in-line with the slot. Turn an
extra 1/2 turn (180º) turn using a screw driver.
*** Important: It is a requirement of Instantaneous Electric Water Heaters that a
stable flow of water passes through the heater. This requirement can be satisfied by
using a flow stabiliser in the supply to the heater. It should be adjusted to give a flow
temperature of 45-50ºC from the heater.
