Flow Controllers for Gas and Liquid Service
4-1 Maintenance
The FC Series Flow Controllers require no maintenance when installed in a
dirt-free flow line. Repair or disassembly of the regulator in the field is not
recommended. The regulator parts are ultrasonically cleaned and white-
room assembled for trouble free operation. Do not attempt to clean the
regulator by flushing with solvent or air.
The optional filter elements should be periodically inspected and
ultrasonically cleaned or replaced if necessary. When reinstalling the filter
elements use care to prevent any dirt or foreign matter from entering the
lines.
Should the regulator become inoperative, it should be returned to the
factory for repair or replacement.
