2-5 Transit Precautions

2-6 Removal from Storage

2-7 Installation

Any instrument returned to Brooks requires completion of Form RPR003-1,
Brooks Instrument Decontamination S tatement, as well as, a Material
Safety Data Sheet (MSDS) for the fluid(s) used in the instrument. This is
required before any Brooks Personnel can begin processing. Copies of the
form can be obtained from any Brooks Instrument location listed above.

To safeguard against damage during transit, transport the instrument to the
installation site in the same container used for transportation from the
factory if circumstances permit.

Upon removal from storage, a visual inspection should be conducted to
verify the condition of the equipment is “as received.” If the equipment has
been in storage in conditions in excess of those recommended
(See Section 2-3), the device should be subjected to a pneumatic pressure
test in accordance with applicable vessel codes.

2-2

The regulator may be installed in any attitude. Inlet and outlet connection
piping should be rigidly supported to prevent undue strain on the regulator
body. A good quality sealant that is comp atible with the gases involved should
be used on NPT connections.

2-8 Panel Mounting

Section 2 Installation

Model 8601 Pressure Regulator

Extreme care must be exercised to prevent any solids from entering the
regulator. It is recommended that a Brooks Model 1391 Filter or equivalent be
used on the regulator input to protect it from any foreign matter in the flow
stream.

A single 9/16" diameter panel hole is required for panel mounting the
regulator. For front p anel mounting, remove the regulator knob, the knurled
packing nut, and one panel nut. Insert the regulator stem in the p anel
opening. Replace and tighten the panel nut, packing nut, and knob. Do not
over-tighten the knurled packing nut.

Section 3 Operation

Model 8601 Pressure Regulator

Before placing the regulator in operation, make sure all gas connections
are tight. For initial start-up, the supply pressure should not exceed 75 psi
and may afterward be increased to operating level. Supply pressure must
never exceed 250 psi. If a flowmeter is desired for rate indication, it should
be installed on the downstream side of the regulator .

Section 4 MaintenanceInstallation and Operation Manual

Model 8601 Pressure Regulator

4-1 Filter Replacement

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

pushing on the edge (See Figure 4-1). Remove the filter and filter retainer.

Filter Installation:
Locate the filter element into the retainer as shown. Place the filter

assembly into the inlet cavity of the regulator body . Use tool P/N 908-Z­060EAA or a 0.305 diameter rod to press the assembly completely into the
body cavity , ensuring that the filter element s remains seated in the retainer .
