PREFACE
Scope
These instructions include information for the installation and operation of standard Parr
Models 4555, 4556, 4557, 4558, 4667, and 4668 (5G and 10L volume) Reactors. It should be
noted that these reactors can be custom designed to accommodate a customer’s specific
operating parameters. This may impact certain areas of these instructions or related instructions
mentioned within this manual.
These instructions cover the basic steps to be followed in installing these reactors and
describe the function of all principal components. They are intended to be used in conjunction
with several related instruction sheets listed on the previous page which provide information
describing several components which are common to most Parr pressure reaction apparatus.
These instructions also include safety precautions and other information applicable to all
pressure equipment.
The user should study all of these instructions carefully before starting to use these reactors
to fully understand the capabilities and limitations of the equipment, and to be well aware of the
precautions to be observed in the operation.
Safety Information
To avoid electrical shock, always:
1. Use a properly grounded electrical outlet of correct voltage and current handling capacity.
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.
Provisions for Lifting and Carrying
The 4555, 4556, 4557, 4559, 4667 and 4668 (five gallon and ten liter volume) reactors and
their 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.
Caution
Do not use in hazardous atmospheres.
