The Mira Select Flex is a thermostatic mixer with
separate ow and temperature controls. The lever
controls have been designed to be easily operated
by users with restricted hand movement.
The thermostatic mixer incorporates a wax
capsule temperature sensing unit, which provides
an almost immediate response to changes of
temperature of the incoming water supplies to
maintain the selected showering temperature.
An adjustable temperature stop is provided which
limits the maximum temperature to a safe level.
Inlet lters are tted to protect the thermostatic
cartridge.
On exposed models the thermostatic mixer
has adjustable inlets to fit pipework centres
between 139 mm and 153 mm and is designed
for connection to rising, falling or rear entry
pipework.
