Preface
Scope
These instructions describe the installation, operation and maintenance of Parr Series 5500 Compact
Micro Reactors which are offered in three sizes 25,
50 and 100 mL. They cover the basic steps to be
followed when installing these reactors and describe the function of all standard components.
They are intended to be used in conjunction with
several related instruction sheets. This information
describes several components which are common
to most Parr pressure reaction equipment, and
includes safety precautions and other related information applicable to all reaction laboratories. The
users should study all of these instructions carefully
before starting to use these vessels so that they will
fully understand the capabilities and limitations of
the equipment.

Safety Information
To avoid electrical shock, always:
1. Use a properly grounded electrical outlet of correct voltage and current handling capability.
2. Ensure that the equipment is connected to electrical service according to local national electrical codes. Failure to properly connect may create
a fire or shock hazard.
3. For continued protection against possible hazard,
replace fuses with same type and rating of fuse.
4. Disconnect from the power supply before maintenance or servicing.
To avoid personal injury:
1. Do not use in the presence of flammable or combustible materials; fire or explosion may result.
This device contains components which may
ignite such material.
2. Refer servicing to qualified personnel.
General Specifications
Electrical Ratings
Controller ratings are found in the Operating Instructions for the controller supplied with your reactor and on the controller data plate.
Before connecting a controller to an electrical outlet,
the user must be certain that the electrical outlet has
an earth ground connection and that the line, load
and other characteristics of the installation do not
exceed the following limits:
Voltage: Fluctuations in the line voltage should not
exceed 10% of the rated nominal voltage shown on
the data plate.
Frequency: Controllers can be operated from either
a 50 or 60 Hertz power supply without affecting their
operation or calibration.
Current: The total current drawn should not exceed
the rating shown on the data plate on the controller
by more than 10 percent.
Thermocouple: Unless otherwise specified, all Series 4848 Reactor Controllers operate with a Type J
(iron-constantan) thermocouple. The total resistance
of the thermocouple and the lead wires should not
exceed 100 ohms. If the resistance of the thermocouple circuit is higher, it will reduce the sensitivity
of the control system.

This CAUTION symbol may be present on the Product Instrumentation
and literature. If present on the product, the user must consult the appropriate part of the accompanying product literature for more information.
This CAUTION symbol indicates that the surface may be hot.
Protective Earth (PE) terminal. Provided for connection of the Protective Earth (green or green/yellow) supply system conductor.
Environmental Conditions
This instrument is intended to be used indoors.
Operating: 15 °C to 35 °C; maximum relative humidity of 80% non-condensing. Installation Category II
(overvoltage) in accordance with IEC 664. Pollution
degree 2 in accordance with IEC 664.
Altitude Limit: 0 to 2000 meters above sea level.
Storage: -25°C and 65°C; 10% to 85% relative humidity.
Caution!
Do not use in hazardous atmospheres.
Intended Usage
This system has been designed for use as a high
pressure reactor system. It has been designed, built,
and tested to strict physical and electrical standards.
However, it is the user’s responsibility to install and
operate it in conformance with local pressure and
electrical codes.
If this equipment is used in a manner beyond its intended usage, the protection provided by the equipment may be impaired.
Provisions for Lifting and Carrying
The reactor and its components are very heavy. Before moving ensure all cables are disconnected. Use
proper and safe lifting techniques when installing or
moving the reactor and/ or its components.
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 product 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.

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 temperature 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 that has the
capability, pressure rating, corrosion resistance,
and design features that are suitable for its
intended use. Parr engineers will be glad to discuss available equipment and material options
with prospective users, but the final responsibility 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 the 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 pressure 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 recommended 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 customer’s responsibility to provide pressure relief
in order to protect the operator and the equipment 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.
Unpack Carefully
Unpack the equipment carefully and check all the
parts against the packing list. If shipping damage is
discovered, report it immediately to the delivering
carriers. The vessel, motor, heater, and controller
may be packed separately for convenience in shipping, but these parts are easily reassembled. Examine the components closely for any loose parts or
shipping damage and be sure to check all layers of
packing materials thoroughly so as not to overlook
any parts which might otherwise be discarded.

Flat PTFE Gasket or Self Sealing O-Ring Closure
The flat gasket is held in a recess in the vessel head
and a machine pilot on the cylinder closes the recess to completely contain the gasket. The split ring
closure used with this gasket has six cap screws
which must be tightened to develop the loading on
the gasket.
The self sealing design features an O-ring retained
in a groove on the vessel head. This design is self
sealing and the split ring used with this sealing system does not require nor have the cap screws used
with the flat gasket.
The face seal O-ring with screw cap closure is designed to be simply hand tightened.
The flat PTFE gasket can be used to operating temperatures as high as 350 ºC. The maximum temperature of the vessels equipped with O-ring seals
depends upon the material used for the O-ring. The
most common material is a fluoroelastomer (FKM)
which has a 225 ºC maximum operating temperature limit.
