General Information
This product has been tested to comply with the BS EN 1287:1999 (LP) and BS EN
1111:1999 (HP) thermostatic mixing valve standards.
BS6700 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 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.
This shower valve should be installed in compliance with the Water Supply (Water
Fittings) Regulations 1999 and the Scottish Byelaws 2004.

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 6.
•Instantaneous Water Heater
(combination boiler)
•Unvented System
•Pumped System
Gravity Fed Hot and Cold
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 on page 11.
Flushing Pipework
Important: Before connecting the
shower valve (see Installation on pages 17-
18), supply pipework must be flushed to
clear debris before connecting the shower
valve. Debris will reduce the performance
and life of the shower.
