Preface
Scope
These instructions describe the installation, op-
eration and maintenance of Parr Series 4560 Mini
Bench Top Reactors offered in sizes from 100 mL to
600 mL. They cover the basic steps to be followed
for installing these reactors and describe the func-
tion of all standard components. 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 con-
junction with several related instruction sheets listed
on the previous page. This information describes
several components that 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:
Use a properly grounded electrical outlet of correct
voltage and current handling capacity.
Disconnect from power supply before servicing. The
power supply cord of the equipment is the main
disconnect device.
To avoid personal injury:
Do not use in the presence of fl ammable or com-
bustible materials; fi re or explosion may result. This
device contains components which may ignite such
materials. Refer servicing to qualifi ed personnel.
General Specifi cations
Electrical Ratings
Controller ratings are found in the Operating Instruc-
tions for the controller supplied with your reactor.
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.
Inductive Loads: Inductive loads must be limited to
750 watts (1 hp) at 115 volts, or to 1100 watts (1-1/2
hp) at 230 volts. Do not connect these controllers
to the primary (input) side of an auto-transformer
(Variac, Powerstat or the like). The heavy inductive
load on the primary side of such transformers will
destroy the relay. The secondary (output) side of an
auto-transformer can be carried through the relay if
this circuit is isolated from the controller. A sepa-
rate, full-voltage connection must then be made to
operate the temperature controller and to actuate
the relay.
Thermocouple: Unless otherwise specifi ed, all
Series 4848 Controllers operate with a Type J (iron-
constantan) thermocouple. The total resistance of
the thermocouple and the lead wires should not ex-
ceed 20 ohms. If the resistance of the thermocouple
circuit is higher, it will reduce the sensitivity of the
control system.
