Change the heating bath fluid
To change the heating bath fluid, proceed as described in the preceding section “Fill/
empty the heating bath” on page 112:
➜ Emptying the heating bath, see “Empty the heating bath” on page 113.
➜ Filling the heating bath, see “Fill the heating bath” on page 112.
➜ Observe the instructions in section “Bath fluid selector” on page 112!
When changing the bath fluid, the heating bath and the drain tube
between the heating bath and the drain valve must be thoroughly
cleaned and dried.
In particular, when changing from water to oil, make sure that the
heating bath temperature is only slowly and gradually augmented
during restart (recommendation: 10 °C), so that remaining water in
the system can evaporate until the process temperature is reached.
