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.

CLEANING
CARE OF YOUR SHOWER VALVE
We recommend cleaning the valve with a soft damp cloth.
We strongly advise against the use of ALL cleaning products.

INTRODUCTION
DIMENSIONS
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 will also be
necessary to fit non-return valves on both hot and cold feeds. 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.
Preparation and bylaw requirements
These taps are single flow so the hot and cold water mix in the body. Water bylaws require that
where the hot water is supplied from a tank and cold from the mains, non return valves are
fitted on both hot and cold pipes as close as possible to the tap. These are not supplied. Where
combination boilers are fitted it is only necessary to shut off the incoming mains and turn the
boiler off, non return valves are not required.
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

INSTALLATION
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.

SCREWS
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.
Preparation.
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 pipes 25mm out from the face of the wall,
see fig 1.
HOT INLET
Remove the nuts and olives and place the valve over pipes, mark the position of the back
plate and remove. Remove the back plate from the valve by loosening the grub screw
underneath, position the back plate onto the wall with the grub screw at the bottom and mark
the position of the 3 holes. Drill the 3 x 6mm holes to a depth of 40mm and insert the wall
plugs. Fix the back plate to the wall with the supplied screws

Slide the cover plates onto the nuts and position on each pipe with the cover plate against
the wall, slide an olive onto each pipe. Push the valve over each pipe and into the back plate,
tighten the 2 nuts onto hot and cold inlet, and then the grub screw underneath the valve.
Finally connect the valve the riser.
Note: There is the option to fit the valve as described and then move the stopper from bottom
outlet to the top. This will allow for a flexible hose to be used.
Having first checked all new connections, turn on the mains stop cock, close all taps except
the new valves and as the system starts to refill check for leaks.
Once you have satisfied yourself that there are no leaks, switch on the water heating.

REFITTING HANDLES
The control handles on this product are factory
set and should require no adjustment. However,
if for any reason the handles and/or the mixing
cartridge is removed it is important the following

finished.
SLOT IN BODY
Wash the cartridge with clean running water,
dry and lightly grease the seal. Fit cartridge
