COMMISSIONING
Maximum Temperature Setting
Before using the shower the maximum temperature
must be checked to make sure that it is at a safe
level. 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 sufficient supply.
For Type 2 installations the maximum blend
temperature is determined by the application,
refer to he TMV2 Requirements Manual.
1.
Turn on the mixer to the maximum temperature
and maximum flow (i.e. fully anticlockwise) and
allow the temperature to stabilise.
If the temperature is too hot or too cold adjust
as follows:
5.
Insert the 2.5 mm hexagon key into the centre
of the spindle and engage with the recessed
temperature adjusting screw.
6.
Rotate the hexagon key until the required
maximum temperature is obtained at the
shower. Rotate anticlockwise to increase the
temperature, or clockwise to decrease the
temperature (¼ turn = approximately 1°C).
7.
Once the desired maximum blend temperature
has been achieved turn off the mixer by
rotating the hub fully clockwise.
Note!
Do not remove the
hub.
8.
Refit the hub retaining screw.
9.
