SAFETY : WARNINGS
WARNING - This product can deliver scalding temperatures if not operated, installed
or maintained in accordance with the instructions, warnings and cautions contained
in this guide.
The function of a thermostatic mixing valve is to deliver water consistently at a safe temperature.
In keeping with every other mechanism, it cannot be considered as functionally infallible and
as such, cannot totally replace a supervisor’s vigilance where that is necessary. Provided it is
installed, commissioned, operated and maintained within manufacturers recommendations,
the risk of failure, if not eliminated, is reduced to the minimum achievable.

INSTALLATION
Suitable Plumbing Systems
Gravity Fed:
The thermostatic mixer must be fed from a cold water cistern (usually tted in the loft space) and
a hot water cylinder (usually tted in the airing cupboard) providing nominally equal pressures.
Gas Heated System:
The thermostatic mixer can be installed with a combination boiler.
Unvented Mains Pressure System:
The thermostatic mixer can be installed with an unvented, stored hot water system.
Mains Pressurised Instantaneous Hot Water System:
The thermostatic mixer can be installed with systems of this type with balanced pressures.
Pumped System:
The thermostatic mixer can be installed with an inlet pump (twin impeller). The pump must
be installed on the oor next to the hot water cylinder.
