3. Unscrew and remove fixing nut
J
with open-end spanner 19 mm A. F. Pull electrodes cables
through the fixing nut
J
.
4. Remove terminal box and pull electrode lines through the hole of the fixing screw.
5. Remove gasket
A between electrode and terminal box.
Mounting the terminal box
1. Depending on the desired position of installation, unscrew the corresponding sealing plug O and
screw it into the bore in which the electrode rod was previously screwed, Fig. 4 .
2. Put gasket
A
onto the electrode rod. Use only undamaged gaskets.
3. Pull electrode cables through the now free bore in the terminal box and put the terminal box onto
the electrode rod, making sure that the gasket fits correctly between the electrode rod and the
terminal box.
4. Pull electrode cables through fixing nut J . Use a 19 mm A. F. spanner to attach the fixing nut J to
