Safety
This thermostatic shower must be installed and commissioned correctly to ensure that water is
supplied at a safe temperature to suit the users.
The shower is pre-set using ideal conditions to 38°C at the stop with a manual push button
override to 46°C (can be re-set to suit site conditions or user preference – see calibration
page 13).
The maximum mixed temperature takes account of the allowable tolerances inherent in
thermostatic shower mixers and temperature losses.
It is not a safe bathing temperature for adults or children
.
The British Burns Association recommends 37 to 37.5˚C as a comfortable bathing
temperature for children. In premises covered by the Care Standard Act 2000, the maximum
mixed water outlet temperature is 43˚C.
