During priming an audible noise was noted coming from the revolution centrifugal head. There were also vibrations noted noted arising in the tubing. The unit was changed out pre bypass as it was felt that it was not appropriate to continue with this particular unit. The replacement unit removed the audible noise and vibrations and there were no subsequent issues.
