PREFACE
Scope
These instructions describe the installation, opera-
tion and maintenance of Parr Series 4530 Floor
Stand Reactors offered in one and two liter sizes.
They cover the basic steps to be followed install-
ing 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 informa-
tion describes several components which are com-
mon to most Parr pressure reaction equipment and
includes safety precautions and other related infor-
mation 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 cor-
rect voltage and current handling capability.
2. Ensure that the equipment is connected to elec-
trical service according to local national electri-
cal codes. Failure to properly connect may create
a fi re or shock hazard.
3. For continued protection against possible haz-
ard, replace fuses with same type and rating of
fuse.
4. Disconnect from the power supply before main-
tenance or servicing.
To avoid personal injury:
1. 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 material.
2. Refer servicing to qualifi ed personnel.
General Specifi cations
Electrical Ratings
Controller ratings are found in the Operating In-
structions for the controller supplied with your reac-
tor 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 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.
