Model 8601 Pressure Regulator
4-1 Maintenance
The Brooks 8601 Regulator requires no maintenance when installed in a
dirt-free flow line. Except for filter replacement, repair or disassembly of the
regulator in the field is not recommended (see Filter Replacement). The
regulator parts are ultrasonically cleaned and clean-room assembled for
trouble-free operation. Do not attempt to clean the regulator by flushing
with solvent or air.
Should the regulator become inoperative, it should be returned to the
factory for repair or replacement. If the unit is disassembled in the field, the
warranty is voided and no credit will be issued by the factory.

Filter Removal:
Using a thin screwdriver or a pair of tweezers, rotate the filter 180° by

Filter Installation:

assembly into the inlet cavity of the regulator body. Use tool P/N 908-Z-
060EAA or a 0.305 diameter rod to press the assembly completely into the
body cavity, ensuring that the filter elements remains seated in the retainer.
