Intended Usage
This apparatus 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 be-
yond its intended usage, the protection provided by
the equipment may be impaired.
The User’s Responsibility
The user must realize that it is their responsibility
to keep their equipment in good condition and to
use it only within the prescribed temperature and
pressure limits. They must be constantly aware of
the serious consequences that can result from such
things as: opening the wrong valve, mixing com-
bustible vapors with air or oxidizing gases, adding
reactants too fast or failing to observe and prevent
sudden increases in temperature or pressure. Quali-
fi ed personnel should make frequent checks to be
sure that all safety rules are being observed. In the
absence of a supervised safety program the user
must take time to become completely familiar with
their equipment and to consider any hazards inher-
ent in the reactions they intend to perform.
Unpack Carefully
Unpack the equipment carefully and check all the
parts against the packing list. If shipping damage
is discovered, report it immediately to the deliver-
ing carriers. Examine the components closely for
any loose parts or shipping damage and be sure to
check all layers of packing materials thoroughly so
as not to overlook any parts which might otherwise
be discarded.
Cleaning & Maintenance
Periodic cleaning may be performed on the exterior
surfaces of the instrument with a lightly dampened
cloth containing mild soap solution. All power
should be disconnected when cleaning the instru-
ment.
There are no user serviceable parts inside the prod-
uct other than what is specifi cally called out and
discussed in this manual. Advanced troubleshooting
instructions beyond the scope of this manual can
be obtained by calling Parr Instrument Company in
order to determine which part(s) may be replaced or
serviced.
CAUTION!
Ensure that any hot surfaces have had
adequate time to cool before cleaning or
maintaining the hydrogenation apparatus
and/or its components.
