SPECIFICATIONS

For Type 2 Valves, the supply conditions specied

in section: ‘Type 2 Valves - Application’ take
precedence over the operating parameters which
follow.

Pressures

Max Static Pressure: • 10 Bar.
Max Maintained Pressure: • 5 Bar.

Min Maintained Pressure (Gravity System): •

0.1 Bar. (0.1 bar = 1 Metre head from cold

tank base to shower handset outlet.)

Note! For gravity fed / other low pressure

systems (0.5 bar or below) do not t the outlet
ow regulator.

For optimum performance supplies should be •

nominally equal.

Temperatures

Factory Pre-set (Blend) Shower: • 41°C.
Optimum Thermostatic Control Range: • 35°C

to 43°C (achieved with supplies of 15°C cold,

65°C hot and nominally equal pressures).

Recommended Hot Supply: • 60°C to 65°C

Note! The mixing valve can ope rate at
higher temperatures for short periods without
damage, however this could detrimentally
affect thermostatic performance. For safety
and performance reasons it is recommended
that the maximum hot water temperature is
limited to 65°C.

Cold Water Range: up to• 25°C.
Minimum Recommended Differential between •

Hot Supply and Outlet Temperature: 12°C.

Thermostatic Shut-down

For safety and comfort the thermostat will •

shut off the mixing valve within 2 Seconds if
either supply fails (achieved only if the blend
temperature has a minimum differential of

12°C from either supply temperature).

Connections

Inlets: 15 mm Compression.•
Outlet: ½” BSP Flat Face.•
Standard connections are: • hot - left, cold -

right, outlet - bottom.
