Page 10 Section 5: TROUBLESHOOTING 5.10 Vacuum Problems Leakage, contamination and unusual outgassing are the general causes of problems with poor vacuum. To operate at maximum efﬁ ciency a system must be thoroughly clean. If the system is completely clean and free from leaks, and unwarranted vacuum problems still exist, the pump should be checked. A simple criterion for the condition of the pump is the determination of its maximum vacuum capability.
