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 (0.5 Bar for models with Eco
Showerhead). (0.1 bar = 1 Metre head from cold tank base to showerhead outlet).
Note: For gravity fed or other low pressure systems (0.5 bar or below) do not fit the outlet
flow regulator (where applicable).
• For optimum performance supplies should be nominally equal.
Temperatures
• Factory Pre-set (Blend) Shower: 43° C.
• Optimum Thermostatic Control Range: 35° C to 45° 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: Mixing valve ONLY accepts 15mm OD copper pipe.
IMPORTANT This product is not suitable for use with any other pipe sizes
• Outlet: ½" BSP Flat Face
• Standard connections are:
• Hot - Left, Cold - Right
• Outlet - Bottom
WARNING! This product does not allow for reversed inlets and will deliver dangerously
unstable temperatures if fitted incorrectly.
Suitable Plumbing Installations
Gravity Fed:
The thermostatic mixer must be fed from a cold water cistern (usually fitted in the
loft space) and a hot water cylinder (usually fitted in the airing cupboard) providing
nominally equal pressures.
Mains Pressurised Instantaneous Hot Water System (Combination Boiler):
The thermostatic mixer can be installed with systems of this type with balanced
pressures (Recommended Minimum Maintained Pressure: 1.0 Bar).
