What happens if the rupture disc on the small side primary pump blows, and what should I do?

If the rupture disc ever opens, do not operate the machine until both the over pressure valve and the rupture disc have been replaced. The rupture disc is provided on the small side primary pump (pumps 145 cc and smaller) as a back-up to the over pressure relief valve. You should also determine the cause of the over-pressurization and correct it before replacing the rupture disk assembly (258962) and the over-pressure relief valve (302). (Pages 10, 44)
