5. Open the desired paraffin tab - P1, P2, P3 or P4 (see Fig. 24, B and

C):

6. Completely empty the paraffin container.

7. Lock the paraffin tab closed again (see Fig. 25).

Let the paraffin drip for a short time so there is no paraffin left in

the drain.

8. Push the rail back into the device.

9. Close the protective cover.
