Failure to do the above could result in personal injury or
property damage
Vent Opening
Make sure the regulator vent, vent assembly, or vent tube
does not become plugged by mud, insects, ice, snow,
paint, etc. The vent screen aids in keeping the vent from
becoming plugged, and the screen should be clean and
properly installed.
Water inside Regulators from
Floods, Weather, or Water Table on
Underground Systems
Replace any regulator that has been ooded or has been
submersed below the water table of an underground tank,
have had water in their spring case or show evidence
of external or internal corrosion. Checking for internal
corrosion can be done by removing the closing cap and
with the aid of a ashlight observing the condition of the
relief valve spring, main spring, and internal spring barrel
area. A more detailed examination will require shutting
down of the gas system and the complete removal of the
adjusting screw. Closely examine regulators installed
with their vent horizontal for signs of corrosion. Correct
any improper installations.
Regulator Replacement
Older regulators are more likely to catastrophically
fail because of worn or corroded parts. Replace
R600 and HSRL Series regulators over 20 years of age.
Other service or environmental conditions may dictate
replacement of the regulator before it becomes 20 years
old. Regulators that are installed on underground
systems and in areas that are subject to sea salt
(coastal) atmospheres should be inspected annually
for external and internal corrosion and may require
replacement sooner. Refer to Fisher
®
Bulletin LP-32 for
additional information.
Regulator Repair
Regulators that have been disassembled for repair
must be tested for proper operation before being
returned to service. Only parts manufactured by Fisher
should be used to repair Fisher regulators. Be sure to
give the complete type number of the regulator when
corresponding with the factory.
The type number, orice size, and spring range are
on a label attached to the spring barrel. The date of
manufacture is stamped on the regulator. Always provide
this information in any correspondence with your Fisher
Distributor regarding replacement parts or technical
assistance. If construction changes are made in the eld,
be sure that the regulator marking is also changed to
reect the most recent construction.
