4570 HP/HT Pressure Reactors Parr Instrument Company
ASSEMBLE THE REACTOR
These reactors require at least 10 sq. ft.
of workspace in a well-ventilated area with
convenient access to an electric outlet,
running water, air and a drain.
1. Set the stand in the workspace.
2A. Removable Vessels.
First pivot the overarm assembly to the
back of the support stand.
The pressure vessel has been shipped
as a complete assembly; it may be
easiest on the initial setup to place the
entire pressure vessel assembly into
the heater. Note: The complete
assembly does not need to be removed
from the heater during opening and
closing operations. It is designed so
that the cylinder can remain in the
heater while the head and split rings
are attached or removed.
Once the vessel assembly is in place
rotate the magnetic stirrer by hand to
make sure that it turns freely. Then
move the overarm back into position
above the vessel. The knob on the top
of the overarm will raise the upper shaft
with coupling for attachment to the
adapter on the top of the magnetic
stirrer. Push down and rotate the
upper shaft to bring these components
into alignment.
Occasionally the motor housing and
overarm assembly may vibrate out of
the standard position. If the upper
shaft is not in alignment with the center
of the top of the magnetic stirrer it will
be necessary to loosen the bolt which
attaches the motor housing to the
support stand. Remove the motor
housing panel, there is a single bolt
that runs through the lower housing
support and the top shelf of the floor
stand.
Once the bolt is loosened, rotate the
housing the required amount, connect
the upper shaft to the magnetic stirrer
and then tighten the motor housing
bolt.
2B. Fixed Head Reactor.
Bolt the stand to the floor
using the holes in the
base plate.
Remove the (2) flat head socket cap
screws of the vessel retainer mounted
on the midplate of the support stand
and remove the retainer bracket.
The pressure vessel has been shipped
as a complete assembly. It is
necessary to loosen the split ring bolts
and remove the split ring. Lift the head
assembly out of the cylinder and slide it
into the midplate of the stand. Re-
install the retainer bracket. The
cylinder should be placed in the
cylinder lift bracket.
Pull up on the release knob located on
top of the belt guard. This knob is
attached to the upper drive shaft and
the universal coupling. Lifting the knob
will allow the alignment of the universal
coupling and the drive adapter attached
to the magnetic drive. Turn the knob to
align the slot in the drive adapter with
the universal coupling.
Rotate the magnetic stirrer by hand to
make sure that it turns freely.
Connect an air line to the 1/4” quick
disconnect fitting at the base of the
support stand. This pneumatic lift
package will raise or lower the cylinder.
It may also be used for the heater. The
lever on the side panel of the support
frame controls the lift motion.
