Type 99 Pressure Reducing Regulator
WARNINg
!
Since a pilot-operated regulator is
constructed of both a pilot and a main
valve, care should be used not to exceed
the maximum inlet pressure shown on
the nameplate of either unit. When inlet
pressure exceeds the pilot limitation, a
pilot supply reducing regulator and/or
relief valve is required.

Failure to follow these instructions or
to properly install and maintain this
equipment could result in an explosion
and/or fi re causing property damage and
personal injury or death.
Fisher
regulators must be installed,
®
operated and maintained in accordance
with federal, state and local codes, rules
and regulations and Emerson Process
Management Regulator Technologies,
Inc. instructions.
If the regulator vents gas or a leak
develops in the system, service to the unit
may be required. Failure to correct trouble
could result in a hazardous condition.
Call a gas service person to service the
unit. Only a qualifi ed person must install
or service the regulator.
