After the unit has stabilised the bath temperature (T

1.2 Operating
safety
The thermostat must be operated with non-flammable bath liquids only, or with
flammable bath liquids up to 25°C below their fire point, otherwise there is a possibility
that a flammable atmosphere may form (see Item 4.2).
1.3 WARNING:
Parts of the bath cover may reach temperatures above 70°C when working at higher
temperatures.The outflow and return pipes of the pumps reach the operating
temperature. Touching them is dangerous because of very high or low temperatures.
