1 – Unscrew the nut.
2 - Take out the spool (see fig.21)
fig.21 fig.22
3 – Unscrew the steel sleeve (see fig.22).
4 – Take out the inside cylinder to see whether it needs to
be cleaned, for example from calcium residue.
5 – Unscrew the brass base in order to replace the whole
solenoid valve if necessary.
6 – Reassemble the whole unit carrying out the operations in
reverse order.
