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 65º . A
stored water temperature of 60º 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 the UK 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:
Note: Note:
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
This shower valve should be installed in compliance with the Water Supply (Water
Fittings) Regulations 1999 and the Scottish Byelaws 2004.

If there is no significant change to the set
outlet temperature (+/-2º 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 2º 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.
If all these conditions are met, proceed to
set the temperature as stipulated in the
maintenance section.

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.
•arry 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 46º .
The sensing part of the thermometer probe
must be fully submerged in the water that
is to be tested.
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.
