Servicing
This chapter includes the following parts information and component
replacement procedures.
Thermo Fisher Scientific suggests that you return the entire instrument to
the factory or an authorized service center once a year for cleaning, testing,
and calibration.
From time to time, you must remove and renew several components of the
TVA2020 analyzer. Some components may be replaced as normal
maintenance functions performed by operating personnel. Other
components, however, should be replaced only by personnel thoroughly
trained and familiar with the analyzer instrument and its applications.
