SECTION 5: TROUBLESHOOTING
5.10 VACUUM PROBLEMS
5.11
Leakage, contamination, and unusual outgassing are the general causes of problems associated with
poor vacuum. To operate at maximum efficiency, 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. This can be accomplished by blocking of the intake and reading the vacuum level on
the gauge (See Section 2.80).
5.20 PRESSURE PROBLEMS
5.21
Leakage and contamination are the general causes of problems associated with poor pressure.
To operate at maximum efficiency a system must be thoroughly clean. If the system is completely
clean and free from leaks and unwarranted pressure problems still exist, the pump/compressor should be
checked by a service technician.
