Where extraction of the suction valve unit is especially difficult (i.e. incrustations due to
prolonged lack of use), use an extractor tool #F27516200 (1, fig. 103) as indicated.
Unscrew the valve opening device by means of a 30mm spanner (1, fig. 104).
Remove the suction and outlet valve units, unscrewing an M10 screw in such a way to press on the inner
guide and remove the valve guide from the valve housing (1, fig. 105).
Complete disassembly removing the 1/4” NPT plugs on the front of the head.
