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.

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. Ho wever, it is the user's
responsibility to install and operate it in conformance with local pr essure and electrical codes.

If this equipment is used in a manner beyond its intended usage, the protection provided by
the equipment may be impaired.

User’s Responsibility

All Parr reactors and pressure vessels are designed and manufactured with great care to
assure safe operation when used within their prescribed temperature and pressure limits.
But . . . the basic responsibility for safety when using this equipment rests entirely with the user;
who must:

1. Select a reactor or pressure vessel which has the capability, pressure rating, corrosion

resistance and design features that are suitable for its intended use. Parr engineers will be

glad to discuss available equipment and material options with prospective users, but the final

responsibility for selecting a reactor or pressure vessel that will perform to the user’s

satisfaction in any particular reaction or test must rest with the user – not with Parr.

In exercising the responsibility for the selection of pressure equipment, the prospective
user is often faced with a choice between over - or under-designed equipme nt. The ha zards
introduced by under-designed pressure vessels are readily app arent, but the penalties that
must be paid for over-designed apparatus are often overlooked. Recognizing these criteria,
Parr reactors and pressure vessels are offered in several different styles, each designed for
convenient use in daily operation within certain temperature and pressure limits, using
gaskets, closures and other elements carefully selected for safe operation within the limits
specified for that design. But in order to preserve the validity of these designs, all
temperature and pressure limits must be observed, and no attempt should be m ade to
increase these limits by making alterations or by substituting components which are not
recommended by Parr Instrument Company.

2. Install and operate the equipment within a suitable barricade, if required, with appropriate
safety accessories and in full compliance with local safety codes and rules.

All standard Parr pressure vessels are provided with either a suitable relief device or a
means to attach one (typically in the form of a plugged opening). When a pressure vessel is
delivered without a pressure venting device, it is the customer’s responsibility to provide
pressure relief in order to protect the operator and the equipment from destructiv e high
pressures. If you need more information or need help in selecting a proper re lief device,
please contact Parr Instrument Company.

3. Establish training procedures to ensure that any person handling the equipment knows
how to use it properly.

4. Maintain the equipment in good condition and establish procedu res for periodic testing to
be sure the vessel remains structurally sound.

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 delivering c arriers. The vessel, motor, heater,
and temperature controller may be packed separately for convenience in shipping, but these
parts are easily reassembled. Examine the components closely for any lo ose 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.

INSTALLATION

Pressure and Temperature Limits

The working pressure and temperature at which any reactor or pressure vessel can be

used will depend upon the design of the vessel and the materials used in its construction.
Since all materials lose strength at elevated temperatures, any pressure rating must be
stated in terms of the temperature at which it applies. The standard material of construction
for Parr Instrument Company is Type 316 Stainless Steel.

Limits for vessels made of other materials and for other operating temperatures can be

obtained from Customer Service. No attempt should be made to increase these limits by
making alterations or by substituting components which are not recommended by the Parr
Instrument Company. It must also be understood that lower pressure and temperature limits
may be required for modified reactors and for vessels made of special alloys.

Limits for vessels will be determined by the physical characteristics of the vessel material

and will be prescribed on an individual basis.

Temperature and pressure limits are also affected by the physical properties and

temperature limits of the gaskets and seals used in the vessel, and by any valves, gages or
other fittings attached to the vessel. Obviously, the safe operating pressure of any system
can be no higher than that of its lowest rated component.

All Parr reactors show the maximum safe operating pressure and temperature imprinted

on the cylinder.

The working pressure and temperature in these five gallon and ten liter reactors must not

exceed the following maximum limits:

Cylinder Slide Adjustment

Minimal, if any, adjustments
are required for binding or sagging
of the cylinder slide support.

Note: To adjust for sagging, the
cylinder must be removed from the
Slide Support. This can be done
by leaving the closure intact with
the head and cylinder and
removing the (3) 3/8” nuts from the
bottom of the cylinder standoffs.
Lower the support stand
accordingly. This may require
removal of any plumbing devices
or accessories located on the
bottom of the cylinder.

Caution: The
cylinder is very
heavy and caution
should be
observed when the
cylinder is
disconnected from
the Slide Support.

1. Any adjustments to the Slide Support must be made with the Slider Support in the “IN”

position. Adjustments in the “OUT” position can cause unwanted binding to occur.

2. Once the (3) nuts have been removed from the bottom of the Slide Support, the Slide

Support can be lowered. It can then be leveled by loosening the Angle Support Brackets
detailed in the figure F1. Gently loosen the (8) horizontally mounted 5/16 x ¾” fasteners on
the Angle Support Brackets and adjust the Cylinder Support until it is level. Then tighten the
(8) 5/16 x ¾” fasteners accordingly.

3. Loosen the (4) 5/16 x ½” vertically mounted fasteners on the Angle Support brackets

until the support bracket moves freely. Center (left to right) the Slide Support and ensure
that there is no excessive force being applied against or away from the slide rails. Then
tighten the (4) fasteners accordingly.

4. Raise the Slide Support to the bottom of the cylinder until the standoffs are inserted into

the holes provided on the Slide Support. Attach the Slide Support to the cylinder using the
3/8” nuts previously removed.

IDENTIFY THE VALVES

Gas Inlet Valve

The gas inlet valve is easily identified when the vessel is open by noting that it is

connected to a dip tube which extends to a point near the bottom of the cylinder. Typically,
this is an angle valve with an attached fitting which provides a socket for attaching the
A495HC pressure hose furnished with the reactor.

Gas Release Valve

The gas release valve is connected to a plain opening on the underside of the head. Gas

released from this valve will be drawn from the top of the reactor.

Liquid Sampling Valve

The liquid sampling valve is attached to the same fitting as the gas inlet valve and

connected to the same dip tube. With this arrangement, incoming gas is always introduced
below the surface of the liquid and the operator is provided with a means for clearing the dip
tube to be sure that any sample taken during a run will be representative of the charge. This
can be done by opening the gas valve momentarily to force any liquid in the dip tube back
into the reactor before withdrawing a sample from the sampling valve.

5G & 10L Pressure Reactors

4555 - 58 Series

OTHER VESSEL HEAD FITTINGS

Safety Rupture Disc

There is a safety rupture disc attached to the head which is intended to rupture and

release the pressure before it reaches a dangerous level. A metal tag wired to the safety
head identifies the burst pressure at room temperature for that particular disc. A similar tag
is furnished with each replacement disc. This tag must remain with the apparatus at all
times so that both present and future operators will be aware of the disc rating. Users
should read the discussion of rupture discs given in the Instruction Sheet No. 231M for a
complete description of the characteristics of rupture discs and the precautions to be
observed when operating pressure equipment protected by this type of safety device.

Type J Thermocouple

A Type J thermocouple in a 1/8" dia. stainless steel sheath is furnished with the reactor.

Insert this thermocouple into the head thermowell and connect it to the thermocouple socket
on the rear panel of the temperature controller using the A470E2 extension wire furnished
with the reactor.

Pressure Gage

A pressure gage, typically a 0-2000 psi with a T316 Stainless Steel Bourdon tube, is

mounted on the head using attachment fittings similar to those used for the inlet/sampling
valve assembly

Gage and Valve Adapters

The pressure gage and the combined gas inlet and sampling valves are attached to the

head with an adapter which allows these fittings to be drawn up tightly when facing in any
direction. To attach these fittings to the head, screw the gage or valves firmly into the
adapter, and then run the 209HC4 bushing onto the threaded stem as far as it will go.
Screw this assembly into the head until the nose of the adapter is seated; then back it off
until the valve or gage is facing in the desired direction. Now hold the fitting firmly in place
and close the joint by tightening the 209HC4 bushing. This connection can be made and
broken repeatedly without destroying the sealing faces. A light coating of thread lubricant,
such as Parr No. 424HC2 High Temperature Anti-Seize Lube, applied to the threads and to
the nose of the adapter will help to obtain a tight joint.

HOW TO USE THE VESSEL

The vessels used in Model 4555, 4556, 4557, 4558, 4667 and 4668 Reactors have two

types of closures: fixed head and removable head. They are designed so that the vessel
cylinder and heater can remain together while the head and split rings are attached or
removed.

Flat Gasket or Self Sealing O-ring Closure

The flat gasket is held in a recess in the vessel head and a machine pilot on the cylinder

closes the recess to completely contain the gasket. The split ring closure used with this
gasket has compression bolts which must be tightened to develop loading on the gasket.
The closure is designed so that the compression bolts in the split ring sections must make
contact within a lip on the compression ring which will bring the split sections into their
proper position. When opening these vessels, the compression bolts must be loosened
enough to clear the retaining lip on the compression ring before the split ring sections can
be removed.

The self sealing design features an O-ring retained in a groove on the vessel head. This

design is self sealing and the split ring used with this sealing system does not require nor
have the compression bolts as with the flat gasket.

To Open the Vessel

Open the gas release valve to discharge any internal pressure; then loosen the

compression bolts in the split ring sections (flat gasket design). The split ring sections can
now be removed, and the head with all attached fittings is free to be separated from the
cylinder.

For removable heads, Disconnect the drive by pulling down on the bottom 1743HC

Coupler Halve to disengage the 1746HC Spider from it and swing the lift tube assembly
positioning the lift plate/lift cables over the head and attach the three cables to the lift eyes
in the head until all internal appendages clear the cylinder lip. Rotate the head assembly
around and lower it into the rear service position of the right hand stand assembly. Handle
the head carefully so as not to damage the stirring shaft and other appendages when they
are outside of the cylinder. The cylinder may also be removed from the heater and lowered
into the front service position of the right hand stand assembly.

For fixed heads, slowly and carefully lower the cylinder using the joystick on the

pneumatic lift.

Before Closing the Vessel

Examine the head gasket carefully to be sure that it is in good condition. In flat gasket

designs, after considerable use, some of the PTFE gasket may extrude into a thin, ragged
edge around the inside diameters. This does not necessarily mean that the gasket must be
replaced, but the extruded portion should be removed with a sharp knife. Examine the
mating surfaces on the cylinder and head to be sure they are clean and free from burrs.

- 15 -

5G & 10L Pressure Reactors

4555 - 58 Series

Close the Vessel

For removable heads, lift the head carefully from its service position and lower into the

cylinder. Slide the two split ring sections into place. Tighten each of the compression bolts
with the wrench furnished with the apparatus or with a torque wrench. Tightening should
proceed in a crisscross pattern rather than progressively around the circle. Let the vessel
stand for about five minutes after initial tightening; then tighten the cap screws again. This
will compensate for any tendency of the PTFE gasket to flow under the loading pressure.

The recommended bolt torque for sealing a vessel with a PTFE flat gasket is shown in

the chart below. Rotate the drive into position. Connect the drive by pushing up on the lower
coupler halve to engage it into the spider. Make sure the ball detent of the lower coupler
snaps into position.

For fixed heads, raise the cylinder slowly and carefully in to position. Slide the two split

ring halves into place and secure the latches. Tighten the compression bolts in the same
manner as noted above.

Gas Connections

Gas connections are dependent on applications. For general usage, use the pressure
hose furnished with the reactor. Screw the Type "A" coned pressure fitting into the adapter
attached to the gas inlet valve and tighten the compression nut firmly. Do not use any
thread dope on the coned fitting. The A495HC pressure hose is made of reinforced Nylon
which can be used for all non-corrosive gases at pressures up to 2500 psig. For operations
involving corrosive gases, this hose should be replaced with an A490HC hose which has a
PTFE lining and a braided stainless steel outer covering. An A506HC all metal hose is also
available in stainless steel and other corrosion resistant materials. All of these hoses have
the same fittings.

Pressurizing the Vessel

Check all valves carefully before admitting gas into the system. The liquid sampling
valve must remain closed throughout the charging procedure. The gas release valve must
also be closed unless the vessel is to be purged, or unless there is to be a continuous flow
through the reactor during a run. Always make certain that the pressure in the gas tank is
greater than the pressure in the vessel; otherwise liquid will be forced out of the vessel and
into the gas tank when the inlet valve is opened. If there is any possibility that the tank
pressure might not be high enough to force gas into the reactor, install a one way check
valve (optional) in the gas line to prevent any reverse flow. With the inlet valve open and the

- 16 -

flow control valve on the gas tank closed, open the main valve on the gas tank only about
one-quarter turn; then use the flow control valve or the valve on a pressure regulator to
control the flow of gas into the vessel. After the desired pressure has been reached, close
the tank valves and the vessel inlet valve and disconnect the hose at the vessel end.

5G & 10L Pressure Reactors

4555 - 58 Series

Do Not Overfill the Vessel

Always watch the pressure gage closely when admitting gas so as not to exceed the
maximum working limit. Remember that any subsequent increase in temperature will raise
the pressure. Also, be sure that the amount of liquid placed in the vessel is carefully
controlled. As a general rule, the liquid charge should not exceed two-thirds of the capacity
of the cylinder. Too much liquid in the vessel can lead to development of dangerous
pressures if sufficient space is not provided for expansion when the liquid is heated. This
hazard is explained in greater detail in a warning statement included in the Safety
Instruction Manual No. 230M.

Releasing Pressure

Use the gas release valve to reduce the pressure in the vessel if the reactor is
accidentally overcharged when filling. Use this valve also to release any excess pressure
during a run and to exhaust the vessel at the end of a run. If the discharge gases are
flammable or toxic, discharge to an exhaust hood or to any other safe release point.

Withdrawing Liquid Samples

Liquid samples may be withdrawn from the sampling valve attached to the same adapter
as the gas inlet valve whenever the vessel is pressurized. Always close the inlet valve
before withdrawing a liquid sample and open the sampling valve cautiously because liquid
will be discharged with considerable force. Be particularly careful if the temperature of the
sample is above its boiling point at atmospheric pressure. If so, it will “flash” and be lost as
soon as it is released from the vessel. This problem can be avoided by connecting an
optional 4351 Sample Collection Vessel to the sampling valve to collect the liquid into an
appropriate receiver. The addition of a small amount of gas can be used to clear the dip
tube between liquid samples so that the next sample drawn through the tube will truly be
representative of the mixture.

The Shaft Seal

The stirrer shafts on these reactors are sealed with a magnetically coupled gland.
Operating and Maintenance instructions for these are provided in Instruction Manual No.
234M.

REACTORS WITH SLAVE BOX CONTROLS

Reactors can be set up with a wide variety of heaters. Single zone flexible mantle type
heaters or 3-zone ceramic fiber, band or aluminum block type heaters can be used
depending on the customer’s requirements. For the high powered 3-zone type heaters, Parr
Instrument Company offers a series of slave box controls. Having zone control allows a
wide range of heating power to be selectable by the operator. These slave controls are used
in conjunction with the 4848M Master Controllers.
Note- 3-Zone Heater locations are traditionally:
Zone 1 = Bottom Heater
Zone 2 = Middle Heater
Zone 3 = Top Heater

A1761HCEE 3-Zone Slave Control Box

The A1761HCEE slave control box is supplied with a 250 volt, 50 amp (NEMA 6-50P)
power plug. A 230 volt, 50 or 60 Hz, single phase power supply capable of a maximum
current draw of 40 amperes is required.

The A1761HCEE slave control box has 3 heater outputs each corresponding with a
respective heated zone. There is a 4 position selectable switch, on the front panel, which
can switch the heaters off or turn on zone 1, zones 1 and 2, or zones 1, 2 and 3.

Also located on the front panel are 3 manual reset, high limit switches. These switches
will trip if an alarm condition is present on the master controller. Once the alarm condition
has been resolved, ensure the selector switch is in the “off” position, and reset each switch
by pushing in each button until it latches. These switches may have to be set when the unit
is first powered on.

A1761HC3 3-Zone Slave Box Control

The A1761HC3 slave control box is supplied with an IEC 60309, 5 pin, 32 amp power
plug. A 400 to 415 volt, 3-phase power supply wired in a 5-wire WYE configuration capable
of supplying a maximum of 20 amperes is required.

The A1761HC3 slave control box has 3 heater outputs each corresponding with a
respective heated zone. There is a 4 position selectable switch, on the front panel, which
can switch the heaters off or turn on zone 1, zones 1 and 2, or zones 1, 2 and 3.

Also located on the front panel is a manual reset, high limit switch. This switch will trip if
an alarm condition is present on the master controller. Once the alarm condition has been
resolved, ensure the selector switch is in the “off” position, and reset the switch by pushing it
upwards until it latches. This switch may have to be set when the unit is first powered on.

Initial Operating Test

Read all operating instructions carefully so as to be well acquainted with the correct
procedures for handling the vessel and for operating the controller and other accessories.
An initial operating test should be made, with only water, to check the apparatus before
starting the first experimental runs. For this initial test, fill the cylinder not more than half-full
of water and run the temperature up to 150 °C while checking the apparatus for leaks and
observing the performance of the temperature controller.

ACCESSORIES

Internal Cooling Coils

Cooling coils can be installed in any of these reactors. Reactors purchased without a coil
can have this feature added by ordering the appropriate parts from Parr Instrument
Company.

Cooling coils are made in serpentine configurations. A serpentine coil does not interfere
with the use of a liner. Plugs are available to seal the cooling coil opening when the coil is
not used.

Replacement coils are furnished with excess tubing at the ends to allow for any
adjustments that might be required when installing a new coil. Align the replacement coil
with the internals before retightening the connections. Remove any sharp burrs and attach
the elbow connectors. Use only moderate force when tightening these elbows so that the
ferrules will not be crimped too deeply into the tube. If tightened too hard it will be difficult to
remove the brass ferrules without damaging the tube, making it impossible to reuse the coil
after it has been removed from the vessel head.

Stirrer Drive Systems

Two types of drive systems are available on the 4555 Series Reactors. They are the
direct drive and the gearbox drives. The direct drive has the motor mounted vertically above
the reactor with the drive coupler connected to the motor shaft. This will produce speeds
from 0 to 1700 RPM. The gearbox drive is offered with three different speed ranges. They
are 3:1 ratio, 5:1 ratio, and 10:1 ratio. These are usually used in low RPM, high stirring load
applications.

Quick Disconnect Drive Coupler

The top coupler half is stationary mounted with a set screw to the drive motor shaft. The
bottom coupler half provides vertical movement for quick disconnect of the couplers. The
bottom coupler is held in the up or engaged position by a spring loaded ball that rests in a
detent in the square drive key. The spring loaded ball inside the threaded hole in the bottom
coupler half and is adjustable to obtain the necessary force to hold coupler in drive or
engaged position.

Removable vessel only: If the coupler needs to be adjusted to align the coupler halves
over each, either relocate the drive motor or the overarm plate or, on moveable vessel
designs, loosen the mounting bolts of the 1578HC Top Bearing Housing and move the
A1575HC Series Welded Overarm Assembly as required to align the drive couplers. Tighten
the mounting flange bolts while holding the welded overarm assembly in position.

5G & 10L Pressure Reactors

4555 - 58 Series

Air Motor

Variable stirring speeds from 100 to 2000 rpm can be obtained by replacing the standard
motor with a 1678HC air motor. This motor operates on compressed air which must be
supplied at 20 psig minimum pressure with at least 10CFM available at that pressure. It is
furnished with a speed control valve and oiler, all assembled on a mounting bracket.

To operate reactors equipped with an air motor, mount the drive system firmly on the
heater and connect the air hose to a compressed air line. Fill the oiler with SAE 10 oil and
adjust the oiler to feed one drop per minute into the air stream. For long continuous runs at
high speeds the oiling rate should be increased to three drops per minute.

If the motor becomes sluggish, flush it with a non-flammable solvent in a well ventilated
area. Disconnect the airline and muffler and pour a small amount of solvent into the inlet
port. Rotate the shaft by hand in both directions for a few minutes; then connect the air line
and run the motor until there is not further trace of solvent in the exhaust. If the muffler felts
are dirty, wash them in solvent or replace them. Re-lubricate the motor with a squirt of oil
into the chamber and reassemble. If it becomes necessary to disassemble the motor to
replace the vanes, follow directions given in the instruction sheet published by the Gast
Manufacturing Corp., Benton Harbor, Michigan.

Variable Speed Electric Motor

Reactors are normally equipped with a DC variable speed motor supplied and controlled
through the 4848M/A3600HC_Series controller. Instructions for connecting and operating
these motors are included in the controller Instruction Manual No. 548M. This motor is
usually installed in a drive system designed to produce stirring speeds up to 1700 rpm.

Spare Parts Kit

Parr can furnish spare parts kits for these reactors which will provide a reserve supply of
parts and tools sufficient to handle most normal replacements and emergency repairs during
a year of heavy usage. These kits contain replacement gaskets, packing, O-rings, shafts,
bearings, and rupture discs. They can be ordered from any Parr Dealer or direct from Parr
Instrument Company. The order must specify the reactor size and indicate type of rupture
disc, stirrer drive. It is advantageous to provide the serial number stamped on the vessel
head or cylinder.

5G & 10L Pressure Reactors

4555 - 58 Series

EXPLOSION PROOF OPERATION

If the local safety code requires that equipment installed in the user’s laborat ory must be
explosion proof, there are five possible ignition hazards to be considered:

1. The Motor

The standard variable speed motor is not explosion proof, yet these motors are not unduly
hazardous if operated in a well ventilated location where care is taken to prevent the
accumulation of explosive gases or vapors. To eliminate any possible spark hazard originating
at the motor, Parr can furnish an air motor as described above, or the reactor can be equipped
with a variable speed, encased electrical explosion proof motor which is approved for use in
Class 1, Groups C & D, and Class 2, Groups E, F, & G atmospheres. Explosion proof m otors
are furnished with a temporary power cord and plug which are not explosion proof. The user
should remove this temporary wiring and replace it with an explosion proof wiring as required to
comply with the local electrical code.

2. The Temperature Controller

The 4848M/A3600HC_Series Temperature Controllers furnished with these reactors contain
switches and other elements which are not explosion proof. The mini mal spark hazard
associated with these units can be resolved by installing the controller in a re mote location
outside of the hazardous area or by enclosing it in an approved explosion proof h ousing. If
enclosed within a positive pressure, clean air housing, the discharge from the housing must be
directed into a safe area. If requested, Parr will furnish the long lead wires needed to mount th e
controller in a remote location. If the controller is to be installed in an explosion proof housing,
the user must provide the necessary housing and installation.

3. Slave Box Control

Reactors furnished with 3-zone high power heaters are supplied with a slave control box.
These slave boxes also contain switches and other elements that are not explo sion proof. The
minimal spark hazard associated with these units can be resolved by installing the controller
and slave box in a remote location outside of the hazardous area or b y enclosing it in an
approved explosion proof housing. If enclosed within a positive pressure, clean air housing, the
discharge from the housing must be directed in to a safe area. If requested, Parr will furnish the
long lead wires needed to mount the controller and slave box in a rem ote location. If the
controller is to be installed in an explosion proof housing, the user must prov ide the necessary
housing and installation.

4. The Heater

The elements in the heater could be dangerous in an explosive atmosphere if the surface
temperature of the element becomes high enough to ignite flammable vapors. This hazard must
be evaluated for each individual installation since major modifications are required if the heater
must be isolated from the surrounding atmosphere. Users who consider this a significant hazard
are urged to contact Parr Instrument Company for further discussion and sugge stions which
might be helpful. Parr is currently offering aluminum block heaters (4555 on ly) and circulating
jacketed cylinders which have been used in explosive environments.

5. The Wiring

Unless specifically designed for use in hazardous atmospheres, the wiring in these reactors
will not meet the standards prescribed for explosion proof equipment. Optional, intrinsically safe
barriers are available.

5G & 10L Pressure Reactors

4555 - 58 Series

PERIODIC PRESSURE TESTS

Each cylinder used in a Parr stirred reactor is tested under hydrostatic pressure to 1.3
times its maximum rating before it is released from the factory. Micrometer caliper
measurements are taken during this test to check the deflection of the cylinder walls under
pressure. Excessive deflection or failure of the metal to resume its original dimension after
pressure is released indicates that a cylinder is potentially unsafe and it will be rejected.
Similar tests should be made at regular intervals during the life of each cylinder, and
particularly whenever the user suspects that the equipment has been over-stressed or
damaged.

Some laboratories maintain hydraulic test facilities and make it a rule that all pressure
vessels must be tested at regular intervals. Records are kept of deflections at specific test
pressures so that any increase in deflection becomes a warning that the metal has lost
strength. Any cylinder which fails to return to its original dimensions after application of the
prescribed hydrostatic test should be discarded as unsafe for further use.

Users who do not have pressure test facilities can return any Parr pressure vessel to the
factory for hydrostatic testing and overhaul. This should be done whenever the metal shows
excessive damage from corrosion or whenever an over-pressure or other unusual
occurrence raises any safety questions. To return a vessel for repair, contact Parr
Instrument Company for a return authorization number. Apparatus returned for testing and
overhaul should be shipped prepaid to the Parr Instrument Company, 211-53rd Street,
Moline, Illinois 61265. An order or letter of instructions should be mailed to the same
address, as no repair work will be started without specific instructions and a Health & Safety
Assurance Certification form (F0042) signed by a responsible user.

GENERAL MAINTENANCE NOTES

1. Periodically inspect all electrical wiring and pressure connections for excessive corrosion
or wear. Suspect parts should be replaced by components only supplied by Parr Instrument
Company.

2. Always use appropriate wrenches on all fittings and valves. Never use pliers or pipe
wrenches.

3. Head and cylinder service fixtures are available for convenience and protection of
components during maintenance of your reactor.

4. To reinstall straight thread (NPS) fittings to the head, screw the gage or valves firmly into
the adapter. Run the bushing onto the threaded stem as far as it will go. Screw this
assembly into the head until the nose of the adapter is seated; then back it off until the valve
or gage is facing in the desired direction (no more than one full turn). Hold the fitting firmly in
place and close the joint by tightening the bushing. This connection can be made and
broken repeatedly without destroying the sealing surfaces. A light coating of thread
lubricant, such as Parr High Temperature Anti-Seize Lubricant, applied to the straight
threads and to the nose of the adapter will help to obtain a tight joint. Note: PTFE tape
should be used only on all tapered (NPT) threads, not NPS straight threads.

5. NPT (National Pipe Taper) threads should not be disassembled any more than
necessary. It will become increasingly difficult to maintain a tight seal with these tapered
threads if the joint is made and broken repeatedly.

6. Do not use oil or anti-seize lubricant on threads or fittings if the vessel is to be used with
oxygen.

7. If your vessel is equipped with a loose compression ring, be sure that it is in place on the
head before attaching any head fittings. The compression ring cannot be installed after
fittings have been screwed into the head.

8. Clean all threads and gas passages thoroughly and remove all tape fragments when
overhauling a vessel. An ultrasonic bath is excellent for cleaning metal parts, but do not
place a thermocouple probe, pressure gage, face seals or ball bearings in an ultrasonic
bath. Periodic cleaning may be performed on the exterior surfaces of the reactor stand with
lightly dampened cloth containing mild soap solution. All power should be disconnected
when cleaning.

9. Routinely inspect cap screws on split ring closure for lubrication and cleanliness. It is
important to clean and lubricate periodically with Parr High Temperature Anti-Seize
Lubricant so that the required torque is accurately applied.

- 23 -

10. To operate reactors equipped with an air motor, connect air hose to a compressed air
line. For best torque and speed control the piping to the motor should be at least 3/8" IPS or
larger. Fill the oiler with SAE 10 oil and adjust the oiler feed to a rate of one drop per minute
into the air stream. For long continuous runs at high speeds, the oiling rate should be
increased to three drops per minute.
If the motor becomes sluggish, flush it with a non-flammable solvent in a well ventilated
area. Disconnect the air line and muffler and pour a small amount of solvent into the inlet
port. Rotate the shaft by hand in both directions for a few minutes; then connect the air line
and run the motor until there is not further trace of solvent in the exhaust. If the muffler is
dirty, replace it. Re-lubricate the motor with a squirt of oil into the chamber and reassemble.

11. If servicing assistance is needed, contact Parr Instrument Company directly at the
address shown on the back of these instructions
