SECTION 5: TROUBLESHOOTING
Vacuum Problems
Many vacuum problems are attributable to system leakage or contamination. See Leak Detection
(section 3.21) and Cleaning Contaminants (section 3.31) to address system problems. Pump
operation may be verifi ed by isolating the vacuum inlet from the system and using a gauge (built
in for Model 2060) to verify vacuum vis-à-vis Specifi cations.
Power Failure
If pump does not turn on, the power adapter can be replaced. Contact your Welch representative
for information.
