4878 Automated Liquid Sampler
PREFACE
Scope
These instructions cover the installation and operation of the Parr 4878 Automated Liquid Sampler
as used with Parr Laboratory Reactors and Pressure Vessels. The users should study the instructions carefully before using these instruments so
that they will fully understand the capabilities of
this equipment and the safety precautions to be
observed in its operation.
Applications
The Parr 4878 Automated Liquid Sampler is
designed specifically for use with Parr reactors
and pressure vessels. The sampler system can
be used with reactors from any manufacturer
provided the vessel is equipped with a dip tube
arrangement as is provided as a standard feature
in reactors from Parr. This dip tube extends down
to nearly the inside bottom of the vessel and
typically connects to two valves on the top of the
head. The upper valve is used as a gas inlet valve,
and the lower of the two valves is used as the
liquid sampling valve.
To ensure that the second and subsequent samples
are fresh and indicative of current reactor contents,
it is prudent to first allow some gas to enter the reactor pushing the liquid remaining in the dip tube
from the previous sampling back into the reactor.
As you will see shortly, this Liquid Sampler has
features that allow this function to be automated.
Intended Usage
This instrument 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.

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.
If the instrument is used in a manner not specified by Parr Instrument Company, the protection
provided by the equipment may be impaired.
Establish training procedures to ensure that any
person handling the equipment knows how to use
it properly.
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.

INSTALLATION
General Instructions
Set the controller near the reactor on a sturdy
bench or table where there is convenient access
to an electrical outlet capable of carrying the
appropriate current. Leave a space of at least
twelve inches between the controller and the
reactor so that the controller will not be affected
by radiant heat.
Attach the supplied power cord to the POWER
INPUT connector located on the rear panel of the
4878 Automated Liquid Sampler.
Plug the power cord into a properly grounded
electrical supply outlet.
Main Power Switch
This switch will cut off power to the controller.
Protective Fuses
Main fuses are mounted on the back panel of the
sampler system. These fast acting, 250VAC, 4amp
fuses are intended to protect the sampler system
and supply in case of a fault condition.
CAUTION! Unplug unit before servicing.
For continued protection against possible
hazard, replace fuses with same type and
rating of fuse.
The following are 4878 Automated Liquid Sampler
fuses which are intended to be field serviceable.
