K 90 SW The pump motor is fitted with a temperature monitor which switches off if the motor winding overheats The heater is also switched off simultaneously After the motor winding has cooled down the pump starts up automatically 4 2 Why can a thermostat be dangerous 1 Thermostats are equipped with heaters supplying the necessary heat to the thermostating liquid If the temperature control fails or if the liquid level is too low the heater may reach temperatures which can lead to a fire in the laboratory especially in combination with flammable liquids 2 When using the thermostat as a circulation thermostat a hose may break causing hot liquid to spill and endangering people and goods The safety requirements on thermostats therefore depend on whether o non flammable or flammable liquids are used o operation is with or without supervision The thermostats described in these Operating Instructions are protected against overtemperature and low liquid level when operated according to the regulations FL The units can be operated with non flammable bath liquids and with flammable bath liquids up to 25 C below their fire point EN 61010 on condition that there is a correct adjustment and regular testing see Item 8 12 of overtemperature and low level protection 4 3 Important notes The user is only protected against those hazards which are caused by exceeding the temperature and by low liquid level Further hazards may arise
