LECTRONICS

Periodically, inspect the door latch, trim, catch, and gasket for signs of deterioration. Failure to
maintain the integrity of the door system shortens the life span of the Oven.

Electrical components do not require maintenance. If the oven fails to operate as specified, please
contact your Shel Lab distributor or Sheldon Manufacturing Technical Support for assistance.

IFESPAN

The lifespan of the HEPA filter can vary greatly depending on ambient conditions such as humidity
and temperature, as well as the processes or applications the oven is being used for. The dirtier the
bake out process, the faster the filter will become clogged and constrict airflow through the oven.

A useable life of one ( 1 ) year is common for many cleanroom applications. Replace the filter at
least once per year. Replace more often if the exhaust output is noticeably reduced, or if required
by your production or laboratory protocol, or regulatory requirements.
