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 7). 

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.
