Page 43: Safety Notes
Safety notes Safety notes General safety notes A laboratory thermostat is intended for heating and pumping liquids according to the needs of the user. This leads to hazards by high temperatures, fire, and the general hazards by the use of electrical energy. The user is largely protected through the application of the appropriate standard specifications. - Page 44 Safety notes produced. Ensure appropriate ventilation! • Immersion thermostats have to be fixed carefully at the bath vessels! • Only use bath vessels which are appropriate for the intended operating temperatures! • When changing the bath liquid from water to oil, for temperatures above 100 °C, carefully remove all traces of water, also from tubing and from the external consumer, otherwise ! danger of burns through delayed boiling! •...
