Preface
Scope
These instructions describe the installation, opera-
tion and maintenance of Parr Series 4575/4576 HP/
HT Pressure Reactors offered in two sizes, 500 mL
and 250 mL. They cover the basic steps to be fol-
lowed 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 listed in the following
section. This information describes several com-
ponents which are common to most Parr pressure
reaction equipment, and includes safety precau-
tions 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.

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 pres-
sure and electrical codes. If this equipment is used
in a manner beyond its intended usage, the protec-
tion provided by the equipment may be impaired.
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 Controllers operate with a Type J (iron-
constantan) thermocouple. The total resistance
of the thermocouple and the lead wires should
not exceed 20 ohms. If the resistance of the
thermocouple circuit is higher, it will reduce the
sensitivity of the control system.
