11. If using the 'R' port as a balance line, connect it through a continuous rise to the helm pump bottom connection.
12. If using pressurized reservoir type systems, ensure that the pipe is suitable for at least 7 bar.
13. Clean all pipes and fittings before connecting them to prevent dirt from entering the system.
14. Use good quality ISO VG10 to ISO VG42 hydraulic mineral oil as the hydraulic fluid. Check compatibility with the helm pump and ram manufacturers' specifications.
