Before the opening of the filling hole, put a tray or absorbing textile below the
electrode to avoid the water overflow.
3. Lift up the electrode to such a height that the bolus does not touch the
mounting surface. First of all, fill up the electrode with a special liquid
provided by Oncotherm to avoid algae formation. Use the small bottle with
the label: “Algae control” After this you can fill up the electrode with
distilled water in this position. Use a medical syringe for the filling. Ask for
help for the process because the action needs more than two hands. (See
the picture.)
4. Close one of the filling holes with a screw.
