when not retained by the nozzle retainer (2).
3. Remove all the at head cap screws (1), nozzle retainers (2), nozzles (4), and nozzle
sealing O-rings (3) from the nozzle block (20).
4. Remove the socket head cap screws (5) securing the nozzle block (20) to the
extension tube (6). Remove the nozzle block (20) from the extension tube (6).
5. Remove the ow tube assemblies (19) from the nozzle block (20).
NOTE: The ow tube assemblies (19) could be connected to the extension tube (6)
instead of the nozzle block (20).
6. Remove check valve assemblies (18) from the extension tube (6).
7. Remove socket head cap screws (17) securing the extension tube (6) to the valve
manifold assembly (15). Remove the extension tube (6) from the valve manifold
assembly (15).
8. Remove the ow tube assemblies (16) from the extension tube (6).
NOTE: The ow tube assemblies (16) could be connected to the valve manifold
