Model 8601 Pressure Regulator
2-8 Panel Mounting
A single 9/16" diameter panel hole is required for panel mounting the
regulator. For front panel mounting, remove the regulator knob, the knurled
packing nut, and one panel nut. Insert the regulator stem in the panel
opening. Replace and tighten the panel nut, packing nut, and knob. Do not
over-tighten the knurled packing nut.
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.
