ATTENTION! The wire guide wheels should be directed so they
follow the direction of the wire.
If any deviation is found:
1. Pull out the plug (B).
2. Loosen screws (C).

in position.
2. Pull the pole down through the drain valve hole until it is free in the top of the tank.
3. The pole can now be taken out of the tank through the filling hole.
