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.
