For Type 2 and Type 3 Valves, the supply conditions specified in the TMV2 and TMV3
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 (0.5 bar or below) do not fit the outlet
flow regulator (where applicable).
•
For optimum performance supplies should be nominally equal.
Note! For combination type boilers it may be necessary to fit the flow regulator (supplied) to
restrict the flow through the boiler to ensure it produces a sufficiently hot water temperature.
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
at desired flow rate.
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 (Exposed models), 15 mm Compression (Built-in models)
•
Standard connections are: hot - left, cold - right, outlet - bottom (Exposed models),
top (Built-in models).
Flow Regulator Installation
Flow regulators are supplied with this product and should be fitted in High Pressure systems to either;
1.
Reduce Excessive Force & Flow Rate
2.
Reduce Noise through the mixer due to high or unequal pressures
3.
Stabilise incoming supply temperatures
Important! The fitting of flow regulators will invalidate any TMV2/3 compliance due to the
minimum flow rate requirements. Do not fit the flow regulator in TMV2/3 applications.
