3. Start the fan after making the electrical power connections.
4. Energize the equipment heater.

a. Use enough fresh air (or N2) to remove the smoke, while still being able to achieve and

maintain the necessary temperature.

b. The completion of the burn-off period should be based on the particle level in the oven or

smoke-free exhaust and minimal odor level.

c. Check the filter hold-down nuts after burn-off and tightened as necessary.
d. For best oven particle control, this step should be repeated on a regular basis.



If the equipment must be moved after the burn-off process, use
considerable care.



The binder which strengthened new filters is now burned-off
and the media is very fragile.



Rough handling of either the filter alone or the equipment
with the filter installed is not recommended as it may tear the
media and lead to reduced filter efficiency.



Removal of the filter after heating can also result in damage
to the frame seal, and is only recommended when replacing
the filter.
