NOTE
Reheat element sheaths and fins are manufactured with stainless steel. Regular inspections
are necessary to assure proper cleanliness of the reheating element. Should inspection reveal
corrosion particles on the reheating element or adjoining surfaces (including ducts and
plenums), appropriate cleaning should be performed. Periodic reheating element replacement
may be required to meet specific application requirements.
