Maintenance
Filter elements are subject to wear. In order to maintain system efficiency, optimal
performance and best gas quality, these rules of proper maintenance should be followed:
•
Replace filter elements P, R, M, S at least once per year or when pressure drop
reaches 350mbar.
•
A filter element must be changed after 6 months.
•
B filter element can be cleaned with ultrasonic bath or with back flushing. Intervals of
cleaning depend on application. If necessary replace filter element with new one.
•
The housing O-ring can be damaged during filter element change. To prevent gas leakage
and malfunction replace housing O-ring if necessary. For replacement contact
manufacturer.
•
Damaged components are to be replaced by new ones. If a marked degree of damage is
found, the entire filter is to be replaced.
•
Filter has been designed for a life of 10 years in normal operating environment. After 10
years periodical checks of filter integrity are strongly recommended for safe operation.
•
Carry out a check for leaks once the maintenance work has been finished.
