It is very important that the tubes and pipes are
completely clean: no dirt, chips or burrs are
allowed. Flush all piping before connecting the
high-pressure pump to ensure the system is
clean. Internal surfaces of the piping must not be
corroded. If dirt or rust is not removed, the pump
and the valves can be damaged. In worst case
the pump can be damaged beyond repair!
