P.E.D. Categories
This product may be used as a safety accessory
with pressure equipment in the following Pressure
Equipment Directive 97/23/EC categories. It may
also be used outside of the Pressure Equipment
Directive using sound engineering practice (SEP)
per table below.
Only qualied personnel should install
or service a regulator. Regulators
should be installed, operated, and
maintained in accordance with
international and applicable codes and
regulations, and Fisher
If the regulator vents uid or a leak
develops in the system, it indicates that
service is required. Failure to take the
regulator out of service immediately may
create a hazardous condition.
Personal injury, equipment damage, or
leakage due to escaping uid or bursting
of pressure-containing parts may result
if this regulator is overpressured or
is installed where service conditions
could exceed the limits given in the
Specications section, or where
conditions exceed any ratings of the
adjacent piping or piping connections.
To avoid such injury or damage,
provide pressure-relieving or
pressure-limiting devices (as required
by the appropriate code, regulation,
or standard) to prevent service
conditions from exceeding limits.
Additionally, physical damage to the
regulator could result in personal injury
and property damage due to escaping
uid. To avoid such injury and damage,
install the regulator in a safe location.
Clean out all pipelines before installation of the
regulator and check to be sure the regulator has
not been damaged or has collected foreign material
during shipping. For NPT bodies, apply pipe
compound to the external pipe threads. For anged
bodies, use suitable line gaskets and approved
piping and bolting practices. Install the regulator
in any position desired, unless otherwise specied,
but be sure ow through the body is in the direction
indicated by the markings on the body.
