The water temperature must be restricted to a value set according to the geographical area. Setting to the lowest temperatures
runs the risk of causing condensation on the floor, together with all the other risks this may engender.
If the limit temperatures are not observed, the manufacturer may not be held responsible for any physical injuries or damage
to equipment that may be caused.
