This product has been tested to the Water Regulations Advisory Scheme (WRAS) and
satisfies the requirements of the Water Supply (Water Fittings) Regulations 1999 and
current bylaws.
For full Installation Requirements & Notes (IRN) please visit www.wras.co.uk/directory.
BS7600 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 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 1 metre to ensure adequate performance.
Note: Nominally equal (balanced) inlet supply pressures are recommended for optimum
performance.
This shower valve should be installed in compliance with the Water Supply (Water
Fittings) Regulations1999 and the Scottish Bylaws 2004.

Flow Regulators
This shower valve is supplied with a
5 and 7 litre per minute flow
regulator loose in the box which
must be fitted if the shower valve is
installed in conjunction with an
instantaneous water heater /
combination boiler.
With both flow regulators fitted and
by turning the water heater /
combination boiler to its hottest
setting, will ensure a sufficiently hot
water supply to the shower valve
during winter months (in the UK),
when the mains cold water supply is
at its coldest.
To fit the flow regulators
Remove the inlet elbows ensuring
the filter washer is also removed.
carefully remove the plastic inserts
from the valve inlets and push in the
flow regulators. The green 7 litre per
minute flow regulator must be fitted
to the cold inlet and the yellow 5
litre per minute flow regulator must
be fitted to the hot inlet.
Place the filter washers back into
the elbow nuts and tighten the nuts
fully onto the outlets.
In the event that this shower valve
is not installed with an
instantaneous water heater /
combination boiler, the flow
regulators do not need to be fitted.

finished Fit the rubber washer to
the back of the wall outlet, place
the assembly through a
25-30mm hole in the wall and secure
with the backnut ensuring the
washer is fitted between the
backnut and the wall.
Connect the wall outlet assembly
to the shower valve outlet.
b: Without rear access once wall
finished

Tips:Apiece of insulation or masking
tape positioned where holes are to
be drilled and before marking out the
exact position for the fixing holes will
help stop the drill bit from wandering,

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 product 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.
Cartridge Maintenance
We advise that the shower valve is
regularly serviced in hard water areas
to maintain the flow of water.
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 temperature handle
and plastic stop.
Important: Take note of the
position of the plastic stop and handle
-They must be refitted in the same
position.
2. Unscrew the cartridge anti-
clockwise and remove from the
valve body.
3. Remove the piston and thermostat
assembly and place into a bowl.
Carefully add hot water (just off the
boil) and vinegar to de-scale. Leave
in the solution until the water has
cooled and rinse with clean water.
4.Grease the seals with a silicon grease
supplied by Bristan (part number: SP-
495-0002) and carefully refit.
5.Refit the temperature stop and
handle. Reset the maximum
temperature.
