CS400 Series
Change to a new part when reassembling the
regulator. Coat the threads of the replacement
orifice with a good quality lubricant. (If the orifice
is being replaced with a different size, update the
nameplate to state the new size and maximum
inlet pressure).
5. Reassemble the regulator in reverse order of the
above steps.
Regulator Reassembly
As indicated by the square callouts in Figures 8
through 12, it is recommended that a good quality pipe
thread sealant be applied to pressure connections
and fittings and a good quality lubricant be applied
to O-rings. Also apply an anti-seize compound to the
adjusting screw threads and other areas as needed.
