General Information
Operating pressure range: Minimum 0.1 bar, Maximum 5.0 bar.
Maximum static pressure: 10.0 bar.
This product has been tested to the TMV2 scheme which complies with the BS EN
1287:1999 (LP) and BS 1111:1999 (HP) thermostatic mixing valve standards and satisfies
the requirements of the water supply (water fittings) regulations 1999 and current
bylaws.
BS 6700 recommends the temperature of stored water should never exceed 65°C.
A stored water temperature of 60°C 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 28).
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: Nominally equal (balanced) inlet supply pressures are recommended for optimum
performance with mixer showers.
These shower valves should be installed in compliance with the Water Regulations.
If in doubt, contact a registered plumber or your Local Water Authority or the Secretary

Installation Requirements
This shower valve must be installed
in compliance with current water
regulations. If you have any doubts about
the water regulation requirements contact
your local water services provider or use
the services of a professional plumber.
This shower valve is suitable for use with
the following water supply systems:
• Gravity Fed Hot and Cold
(pressure balanced)
• Gravity Fed Hot and Mains Cold
(differential pressure - see Specification
section on page 13)
• Instantaneous water heater
(combination boiler)
• Unvented System
• Pumped System
Gravity Fed Hot and Cold Gravity Fed Hot and Mains Cold
cold mains supply cold mains supply
Important: If you install this shower
valve with a gravity fed system, there must
be a minimum head (vertical distance)
from the underside of the cold water
storage tank to the showerhead position
of at least 1 metre.
Note: Pumped system (with Essex
flange) If you install this shower valve to
a pumped gravity fed system where the
minimum head (vertical distance) from
the underside of the cold water storage
tank to the top of the hot water cylinder
is less than 1 metre we recommend an
Essex flange is used as shown.
Flushing Pipe-work
Important: Before connecting the
shower valve (see ‘Installation’ on pages
16-23), supply pipe-work must be flushed
to clear debris before connecting the
shower valve. Debris will reduce the
performance and life of the shower.

Maximum Static Pressure (Bar) 10 10
Flow Pressure, Hot & Cold (Bar) 0.5 to 5 0.1 to 1
Hot Supply Temperature (˚C) 55 to 65 55 to 65
Cold Supply Temperature (˚C) Equal to or Less than 25 Equal to or Less than 25
Note: Valves operating outside these
conditions cannot be guaranteed by the
Scheme to operate as Type 2 valves.
If a water supply is fed by gravity then
the supply pressure should be verified
to ensure the conditions of use are
appropriate for the valve.
Recommended outlet
temperatures
The BuildCert TMV scheme recommends
the following set maximum mixed
water outlet temperatures for use in all
premises:
44˚C for bath fill but see notes below;
41˚C for showers;
41˚C for washbasins;
38˚C for bidets.
The mixed water temperatures must
never exceed 46˚C.
The maximum mixed water temperature
can be 2˚C above the recommended
maximum set outlet temperatures.
Note: 46˚C is the maximum mixed water
temperature from the bath tap. The
maximum temperature takes account of
the allowable temperature tolerances
inherent in thermostatic mixing valves and
temperature losses in metal baths.
Warning: It is not a safe bathing
temperature for adults or children.
The British Burns Association
recommends 37 to 37.5˚C as a
comfortable bathing temperature for
children. In premises covered by the Care
Standards Act 2000, the maximum mixed
water outlet temperature is 43˚C.
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 mixing valve.

Selecting Flow Regulators
Regulators can be fitted if water economy is required.
Yellow (5 litre) regulator may not be necessary on some gas water heaters.
Important: It is a requirement of Instantaneous Electric Heaters that a stable
flow of water passes through the heater. This requirement can be satisfied by
using a ‘flow stabiliser’ fitted prior to the heater and should be adjusted to give a
temperature of between 45 - 50˚C from the heater.

1. Inlet positions
The shower valve has three inlet positions
- top, bottom and rear. Rotate the inlet
elbows as required.
With the elbows screwed fully against
the valve body it can be unscrewed a
maximum of 1.5 turns to allow for lateral
tolerance.
Sufficient 15mm diameter supply pipes
should protrude through the finished
wall surface to fit fully into shower valve
elbows.
2. Attach backplate to wall
Loosen the ‘backplate’ grub screw on the
back of the valve using the hexagonal key.
Use the backplate as a template and mark
the centres of the fixing holes onto the
wall.
Warning: Please check for any hidden
pipes and cables before drilling holes in
the wall.
Drill suitable holes and insert the wall
plugs. Securely attach the backplate to
the wall using countersunk screws (17).
Note: If required, any decorating should
be complete now before starting the
Second Fix (page 17).

3. Fit wall outlet
There are two methods of fixing the wall
outlet depending on the type of wall:
a: With rear access once wall finished
Remove the backnut from the wall outlet
(12). Insert the wall outlet through a 21-
24mm hole in the wall and secure with the
backnut.
Plumb in the wall outlet assembly to the
shower valve outlet.
b: Without rear access once wall finished
Fit a ‘wall plate elbow’ (not supplied)
within the wall cavity and plumb in from
the shower valve.
Once the wall has been finished, remove
the backnut from the wall outlet (12).
Note: The backnut is not required.
Screw the wall outlet into the ‘wall-plate
elbow’ using a suitable thread sealant.
Note: If required, any decorating should
be complete now before starting the
Second Fix (page 20).
Important note: Please note the depth of
the cavity required to mount the recessed
shower valve. From the back face of the
valve to the front face of the tiling should
be between 68-77mm to ensure correct
fixing of the concealing plate.
Take care to protect the shower valve
whilst finishing the surround.

1. Fit concealing plate
Note: The concealing plate (2) can be
used as a template by drawing around the
plate and measuring in by 15mm to give
sufficient clearance.
Run a bead of silicon sealant around
the groove on the rear outer seal. Use a
smear of washing up liquid around the
inner seal (this will help when fitting over
the valve lever).
Slide the concealing plate over the valve
lever and press firmly against the tiling
around the edges.
Note: If required the valve lever can be
removed from the valve before fitting
the concealing plate. Remove the plastic
cap, loosen the grub screw using the
hexagonal key (10) and carefully pull the
lever off. Once the concealing plate is
fitted, re-fit the valve lever.
