User’s Responsibility
All Parr Reactors and pressure vessels are designed
and manufactured with great care to assure safe
operation when used within their prescribed tem-
perature and pressure limits. But . . . the basic
responsibility for safety when using this equipment
rests entirely with the user; who must:
1. Select a reactor or pressure vessel which has the
capability, pressure rating, corrosion resistance
and design features that are suitable for its in-
tended use. Parr engineers will be glad to dis-
cuss available equipment and material options
with prospective users, but the final responsi-
bility for selecting a reactor or pressure vessel
that will perform to the user’s satisfaction in any
particular reaction or test must rest with the user
– not with Parr.
In exercising the responsibility for the selection
of pressure equipment, the prospective user is
often faced with a choice between over- or under-
designed equipment. The hazards introduced
by under-designed pressure vessels are readily
apparent, but the penalties that must be paid for
over-designed apparatus are often overlooked.
Recognizing these criteria, Parr reactors and
pressure vessels are offered in several different
styles, each designed for convenient use in daily
operation within certain temperature and pres-
sure limits, using gaskets, closures and other
elements carefully selected for safe operation
within the limits specified for that design. But in
order to preserve the validity of these designs,
all temperature and pressure limits must be
observed, and no attempt should be made to
increase these limits by making alterations or by
substituting components which are not recom-
mended by Parr Instrument Company.
2. Install and operate the equipment within a
suitable barricade, if required, with appropriate
safety accessories and in full compliance with
local safety codes and rules.
All standard Parr pressure vessels are provided
with either a suitable relief device or a means
to attach one (typically in the form of a plugged
opening). When a pressure vessel is delivered
without a pressure venting device, it is the cus-
tomer’s responsibility to provide pressure relief
in order to protect the operator and the equip-
ment from destructive high pressures. If you
need more information or need help in selecting
a proper relief device, please contact Parr Instru-
ment Company.
3. Establish training procedures to ensure that any
person handling the equipment knows how to
use it properly.
4. Maintain the equipment in good condition and
establish procedures for periodic testing to be
sure the vessel remains structurally sound.
heater assembly on to the base of the cart using
the provided mounting holes. The gas feed rack is
located on the left side of the cart and the reactor
is on the right. The racks should be mounted to the
cart using the provided bolts and wing nuts. These
nuts should be checked periodically to ensure that
they are tight.
Cleaning & Maintenance
Periodic cleaning may be performed on the exterior
surfaces of the instrument with a lightly dampened
cloth containing mild soap solution. All power should
be disconnected when cleaning the instrument.
There are no user serviceable parts inside the prod-
uct other than what is specifically called out and
discussed in this manual. Advanced troubleshooting
instructions beyond the scope of this manual can
be obtained by calling Parr Instrument Company in
order to determine which part(s) may be replaced or
serviced.
Ensure that any hot surfaces have had
adequate time to cool before cleaning
or maintaining the reactor and/or its
components.
