INTRODUCTION
Please read these instructions carefully and keep in a safe place for future reference.
General Installation Requirements
The installation must comply with regulations of the Local Water Authority as contained in
their bylaws. All of the taps in this range are single flow (the hot and cold water mix in the
body) and should therefore be supplied with hot and cold water at balanced pressures,
both from the tank or both from the mains (via a combination boiler for example). If the taps
are not supplied at balanced pressures then the mixer will not function correctly. It is very
important that all pipe work is flushed thoroughly after installation to avoid damaging the
ceramic discs.
Minimum/Maximum working pressure
These taps are suitable for high and low pressure installations they are fitted with a ceramic
disc cartridge which provides a good flow rate with very smooth movement. To ensure that
the mixer works adequately under low pressure, the cold water storage tank should be at
least 2 metres above the highest installed position. The maximum water pressure is 10 bar
(note: mains cold water is normally supplied at between 2 and 3 bar).
For installations where the mains pressure exceeds 5 bar a pressure reducing valve
should be fitted.
Approvals
All products are manufactured using materials tested and approved under the Water Bylaws
Scheme and comply with requirements of British Standard 5412: 1996 where applicable.
WARNING
Before installing the new mixer it is essential that you thoroughly flush through the
supply pipes in order to remove any remaining swarf, solder or other impurities.
Failure to carry out this simple procedure could cause problems or damage to the
workings of the mixer.
These hints have been prepared for your guidance, you must exercise due care at all times.
We do not accept responsibility for any problems that may occur through incorrect
installation.

CLEANING
TROUBLE SHOOTING
SYMPTOM SOLUTION
After installation the shower runs HOT or
COLD and will not mix.
Hot and cold supplies are plumbed the wrong
way round.
Shower will not run hot enough when first
installed.
Maximum temperature needs adjusting, see
‘temperature setting’.
Cold water tracking through the valve into
the hot water system.
Check and clean the filters.
Very low flow or no flow (gravity). Check hot and cold feeds (the valve will shut
down if either the hot or cold supply fails.
CARE OF YOUR SHOWER VALVE & RISER
We recommend cleaning the valve with a soft damp cloth.
We strongly advise against the use of ALL cleaning products.
SHOWER ROSE & HANDSET
Your shower rose and handset has rub
clean nozzles for easy cleaning. Rub
your fingers across the rubber nozzles to
remove any scale or debris.
If you live in a hard water area you might
have to repeat this procedure regularly.

MAINTENANCE
MAINTENANCE
Before carrying out any maintenance please remember to turn OFF all mains
water and turn ON the isolating valves.
FILTERS
Turn off water supply to the valve and remove from the wall. Using a 29 wrench key
undo the retaining nut within each of the inlets. Wash the filters with clean running water
and replace.
FLOW CONTROL CARTRIDGE
The Flow Control Cartridge uses ceramic discs which normally last indefinitely unless
debris manages to get between them. Wash the cartridge with clean running water, dry
and lightly grease the seal.
THERMOSTATIC CARTRIDGES
The concealed thermostatic valve should give trouble free service, but in the event of
failure, servicing is straight forward.
To remove the thermostatic cartridge. Remove the handle/cover - see temperature
setting.
Pull off the stop ring. Using a hexagonal key undo and remove the screw on the
underside of the valve (keep in a safe place) pull the valve out of the body, you can use
the flats on the thermostatic cartridge to aid removal. Wash the cartridge with clean
running water and make sure that any trapped debris has been removed. Dry and lightly
grease the seals (only use silicone grease) and replace the cartridge making sure that
the hole in the cartridge is lined up with the hole in the body, replace and tighten the
hexagonal screw. Replace the stop ring making sure that the stop is at the 12 o’clock
position. Push the control handle onto the splines, tighten the screw, refit the cover.

OPERATION
Turn the Flow control handle away from you to increase the flow of water tothe shower
rose. To divert the water tothe handset press the button and turn the control handle
towards you. Return the control handle tothe upright position with the button on top toturn
off the flow of water.
Turn the Temperature control handle to increase/decrease the temperature. Push down
on the Override button and turn the handle towards you to override the set temperature.
To change the set temperature see section on page 7 Temperature setting.

Removing the handle/cover - unscrew (but do not remove) the hexagonal grub screw on
the underside of the handle/cover, pull off the handle/cover.
Rotate the exposed thermostatic spindle (clockwise for cold, and anti-clockwise for hot)
until the maximum desired showering temperature is set (38°C - suggested maximum “pre-
set” temperature).
Then line up the button on the top of the handle/cover with the stop on the stop ring itself.
Push the handle/cover onto the splines, tighten the screw. The thermostat is now set to its
new temperature and can only be increased or decreased by repeating this process.

INSTALLATION
First shut off your water heating system then, with your mains stop cock closed, open
the lowest hot and cold taps in the house and allow to run until the cold storage tank and
pipes are empty (the hot water storage cylinder always remains full).
Where combination boilers are fitted it is only necessary to turn off the boiler and shut off
the incoming mains.
Fitting isolating valves to the inlet feeds is recommended for ease of maintenance.
INSTALLATION
Remember to turn off the mains water supply before connecting to any
existing pipe work.
Warning! Please check for any hidden pipes and cables before drilling holes
in the wall.
Preparing the pipe work.
As the valve has no means of fixing to the wall it needs to be supported on rigid pipe
work. Prepare the supply pipes (hot on the left and cold on the right) at the required
height with a width of 150mm centres, making the ends of the adaptors level with the
face of the wall, see fig 1.
Screw each connector/non return valve into the adaptors in the wall see fig 2.
Valve.
Push a cover into the inlets in the valve body. Mount the body onto the “S” connectors
and tighten each of the hexagonal mounting screws on the underside of each inlet.

Fixing the riser
Mark a vertical center line from the valve up the wall, slide the riser support onto the riser
from the bottom followed by handset holder, temporally position the riser into the valve.
Mark the position of the riser support on the wall making sure that the riser support is
below the curve of the riser.
Place the bracket on the centre line and mark the position of the two fixing holes.
Drill the 2 x 6mm holes to a depth of 35mm and insert the wall plugs.
Secure the bracket to the wall using the supplied screws, and slide on the cover
(see fig 1).
Secure the shower rose to the riser using the fibre washer (see fig 2).
Remove the riser nut and ‘O’ ring from the valve and slide onto the riser. Push the riser
down into the connection outlet on the valve, slide down the ‘O’ ring and tighten the riser
nut.
Slide the riser support to meet the bracket and screw together. There are 2 flats on the
bracket pillar to aid tightening.
Insert a fibre washer into the long cone end of the hose and screw to the handset.
Insert the second fibre washer into the short cone end of the hose and attach it to the
mixer outlet.
