Maximum Temperature
Note! For Type 2 and Type 3 valves in healthcare installations the maximum blend temperature
is determined by the application, refer to the TMV2 or TMV3 Requirements Manual.
The maximum blend temperature obtainable by the user should be limited, to prevent accidental
selection of a temperature that is too hot.
All Mira Thermostatic mixing valves are fully performance tested and the maximum temperature
is preset to approximately 41°C under ideal installation conditions at the factory.
Site conditions and personal preference may dictate that the maximum temperature has to
be reset following installation.
Temperatures should always be recorded using a thermometer with proven accuracy.
Maximum Temperature Setting
Before using the shower, the maximum temperature level must be checked to make sure that
it is safe. It has been preset to approximately 41°C at the factory, but due to variations in site
conditions the maximum temperature may need adjustment.
Note! Make sure that the hot water temperature is at least 55°C and that there is a sufficient
supply.
1.
Turn on the shower to maximum flow and temperature (i.e. both controls fully anticlockwise)
and allow the temperature to stabilise.
If the temperature is too hot or too cold adjust as follows:
2.
Using a 2.5 mm Hexagon Key (supplied), unscrew and remove the Temperature Control
Lever.
3.
Insert the 2.5 mm Hexagon Key into the centre of the Green Hub and engage with the
hidden Temperature Adjust Screw.
4.
Turn the Hexagon Key until the required maximum showering temperature is obtained.
Turn anticlockwise to increase or clockwise to decrease the temperature (¼ turn =
approximately 1°C).
5.
Once the desired maximum blend temperature has been achieved, turn off the shower.
6.
Refit the Temperature Control Lever.
7.
Check that the showering temperature is correct.
