PREFACE
Scope
These instructions describe the installation, opera-
tion and maintenance of Parr Series 5500 Compact 
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 function of all standard components. They are 
intended to be used in conjunction with several re-
lated instruction sheets listed on the previous page. 
This information describes several components that 
are common to most Parr pressure reaction equip-
ment, and includes safety precautions and other 
related information applicable to all reaction labora-
tories. The users should study all of these instruc-
tions 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 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.
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 100 ohms. If the resistance of the thermo-
couple circuit is higher, it will reduce the sensitivity 
of the control system.
