General Information
This product complies with the BS EN 1111:1999 (HP) thermostatic mixing valve standards and
satisfies the requirements of the Water Supply (Water Fittings) Regulations 1999 and current
bylaws.
Designed to be used within systems designed to BS 6700.
BS 6700 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 the UK on page
24).
If the shower valve 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
2 metres to ensure adequate performance.
These shower valves should be installed in compliance with the Water Regulations. For further
details contact you Local Water Authority.

Recommended Outlet temperatures
We recommend 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 ofthe
allowable temperature tolerances inherent
in thermostatic mixing valves and
temperature losses in metalbaths.
Warning: It is not a safebathing
temperature for adults orchildren.
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 mixingvalve.

Commissioning
Commissioning notes for
Thermostatic Mixing Valves
The first step in commissioning a
thermostatic mixing valve is to checkthe
following:
1. The designation of the thermostaticmixing
valve matches theapplication.
2. The supply pressures are within thevalves
operating range.
3. The supply temperatures are withinthe
valves operating range.
4. Isolating valves (and strainers preferred) are
provided.
If allthese conditions are met, proceed to set
the temperature as stipulated inthe
setting section.
The mixed water temperature at the
terminal fitting must never exceed46ºC.
When commissioning / testing is due the
following performance checks shallbecarried
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 T M V, wait for five seconds, ifthewater
is still flowing check that the temperature
is below46ºC.
If there is no significant change to the set
outlet temperature (+/-2ºC or less change
from the original setting) 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
2ºC above the designated maximum mixed
water outlet temperature setting of thevalve.
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 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 thesetting
section.
The installation of thermostaticmixing valves
must comply with the requirements of the
Water Supply (Water Fittings) Regulations
1999.
16

In-Service Testing
Purpose
The purpose of in service tests is to regularly monitor and record the performance of the thermostatic
mixing valve.
Deterioration in performance can indicate the need for service work on the valve and /or water supplies.
Servicing Intervals
To reduce the buildup of lime scale and to ensure this shower works to its maximum performance, we
recommend this shower isserviced every 6 –12 months depending on the hardness of your water.
Procedure
Using the same measuring equipment or equipment to the same specification as used in the
commissioning section, adjust the temperature of the mixed water in accordance with the manufactures
instructions and the requirement of the application, Carry out the following sequence.
a) Record the temperature of the hot and cold water supplies.
b)Record the temperature of the mixed water at the largest draw-off flow rate.
c)Record the temperature of the mixed water at asmaller draw-off flow rate, which shall be measured. If
the mixed water temperature has changed significantly from the previous test results (e.g. >1K), record the
change and before re-adjusting the mixed water temperature check:
d)That any in-line or integral strainers areclean.
e) Any in-line or integral check valves or other anti-back siphonage devices are in good working order.
f) Any isolating valves are fullyopen.
With an acceptable mixed water temperature, complete the following procedure:
a) Record the temperature of the hot and cold water supplies.
b)Record the temperature of the mixed water at the largest draw-off flow rate.
c) Record the temperature of the mixed water at asmaller draw-off flow rate, which shall be measured.
d) Isolate the cold water supply to the mixing valve and monitor the mixed water temperature.
e) Record the maximum temperature achieved as aresult of (d) and the final stabilised temperature.
f) Record the equipment, thermometer etc.used for themeasurements.
If at step (e) the final mixed water temperature is greater than 41ºC and /or the maximum temperature
exceeds the corresponding value from the previous results by more than about 2K, the need for service
work is indicated.
Note: In-service tests should be carried out with a frequency, which identifies a need for service work
before an unsafe water temperature can result. In the absence of any other instruction or guidance, the
procedure described in Annex Fof D 08 may be used.
17

Annex F of D 08 (informative)
Frequency of In-service tests
General
In the absence of any other instruction or guidance on the means of determining the appropriate
frequency of in-service testing, the following proceduremay be used:
a) 6to 8weeks after commissioning carry out the tests in ‘In-Service Tests’.
b)12 to 15 weeks after commissioning carry out the tests detailed in ‘In-ServiceTests’.
Depending on the results of the above tests, several possibilities exist:
c)If no significant changes (e.g. <1K) in mixed water temperatures are recorded between commissioning
and 6to 8week testing, or between commissioning and 12 to 15 week testing the next in-service test can
be deferred to 24 to 28 weeks after commissioning.
d)If small changes (e.g. 1 to 2K) in mixed water temperatures are recorded in only one of these periods,
necessitating adjustment of the mixed water temperature, then the next in-service test can be deferred
to 24 to 28 weeks after commissioning.
e)If small changes (e.g. 1 to 2K) in mixed water temperatures are recorded in both these periods,
necessitating adjustment of the mixed water temperature, then the next in-service test should be
carried out at 18 to 21 weeks after commissioning.
f)If significant changes (e.g. >2K) in mixed water temperatures are recorded in either of these periods,
necessitating service work, then the next in-service test should be carried out at 18 to 21 weeks after
commissioning.

Maintenance
General Cleaning
Your fitting has ahigh 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 yourmixer
valve is to wipe with a soft damp cloth. Stains
can be removed using washing up liquid. All
bath cleaning powders and liquids willdamage
the surface of your fitting, even the non –
scratch cleaners.
Note: Never use abrasive detergents or
disinfectants or those containingalcohol,
hydrochloric acid or phosphoricacid.
Flow Valve Maintenance
If your shower valve begins to drip it maybe
due to the flow valve letting water pass
through the valve.
Isolate both hot and cold water suppliesto the
mixer valve by either:
•Turning the water supply off atthemains
stopcock or
•Turning off the isolation valves to themixer
valve.
1.Remove the flow control cover cap, loosen
the screw and pull the handle offthe valve
spindle.
2.Using a suitable spannerunscrewthe
valve out from the body and check its
condition.
3. Clean the valve and replace ifnecessary.
4. Push the handle back onto the valvespindle
and replace the handle, screw and handle
cover cap.
Cartridge Maintenance
We advise that the shower valve is regularly
serviced in hard water areas to maintain
optimum performance (see Map of HardWater
Regions in the UKoverleaf).
Isolate both hot and cold water suppliesto the
mixer valve by either:
•Turning the water supply off atthemains
stop cockor
•Turning off the isolation valves to themixer
valve.
1.Remove the temperature control cover cap,
loosen the screw and pull the handle off the
cartridge spindle
2. Remove the plastic stop.Important:
Take note of the position of the plastic stop and
handle –they must be refitted in the same
positions.
3.Unscrew the thermostaticcartridge from
the body.
4.Place the cartridge in a bowl and carefully
add hot water (just off the boil) and vinegar to
de-scale the cartridge. Leave in the solution
until the water has cooled and rinse withclean
water.
5.Grease the seals with a silicon grease
6.Reset the maximum temperature and
refit the handle, screw and handle cover
cap.
