SPECIFICATIONS
For Type 2 Valves, the supply conditions
specified in the TMV2 Requirements Manual
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 showerhead outlet).
Note! For gravity fed or other low pressure
systems do not t the outlet ow regulator.
• For optimum performance supplies should be
nominally equal.
Flow Regulator Installation
Flow regulators are supplied with this product
and should be tted in high pressure systems
to either;
• Reduce excessive force and ow rate.
• Reduce noise through the mixer due to high
or unequal pressures.
• Stabilise incoming supply temperatures.
Important! The fitting of flow regulators will
invalidate any TMV2 compliance due to minimum
ow rate requirements. Do not t the ow regulator
in TMV2 applications.
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 operate 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 / 15 mm Compression
• Standard connections are: hot - left, cold -
right, outlet - bottom (Exposed models),
top (Built-in models).
