Remove the four screws that secure the battery to the sheet metal sides. Remove the battery by first sliding it
to the left, in order to release the hydraulic connections from the holes on the side.
Reassemble all the new components in reverse order, taking care, if necessary, to gently adapt the position
of the manifolds to the hexagonal holes in the side (if necessary) without damaging them. The battery must be
positioned a few millimeters (2-3mm) into the main tank.
