Important -- Please Read Before Use
INTENDED USE AND DESCRIPTION
The Instrument Processor System consists of an automatic Instrument Processor; Zymit LF
Detergent; endoscope trays specific to endoscopes type (bronchoscope, colonoscope,
duodenoscope, etc.) and baffle inserts specific to endoscopes type. The LIC Instrument
Processor, when used in accordance with its labeling, the Zymit LF Detergent, provides
cleaning of remaining protein to validated levels as low as < 1.3 µg/cm² and remaining total
organic carbon (TOC) levels as low as < 1.8 µg/cm².
The Instrument Processor is designed to: (1) clean one endoscope at a time during a
complete processing cycle, (2) replicate the cleaning results only obtained by following the
reprocessing instructions provided in the user’s manual of the endoscope being processed,
and (3) facilitate the healthcare facility’s compliance with reprocessing guidelines published
by SGNA, APIC, AORN, ASGE, CDC, and other professional organizations. The
Instrument Processor provides a continuous, automated cleaning process. Following the
automated cleaning process, the processed endoscope is immediately available for further
processing in accordance with the endoscope manufacturer’s reprocessing instructions to
achieve high level disinfection.
The Instrument Processor is a floor standing apparatus that is approximately the size of a
large office copying machine. It stands approximately 45-5/8 inches in height, 48 inches
wide and 34-3/8 inches deep.
Figure 1: Picture of Instrument Processor showing side and front views
In the center of the apparatus, positioned at approximately tabletop height, is a stainless steel
chamber in which the medical instrument is processed. When loading, the instrument to be
processed is placed on a plastic tray with the distal and proximal ends of each lumen
positioned on opposite sides of the baffle insert.

The tray includes features to hold the instrument safely in place, yet does not prevent the
processing fluids from contacting all of the instrument's external surfaces. The trays are
positioned in the Instrument Processor chamber, the endoscope is placed in the trays and
supported using the hold down features. Then specially designed baffle inserts are slid into
a slot in the baffle so that the instrument is further secured. The areas on the baffle where
the instrument is secured are also designed to allow the processing fluids to freely contact
the instrument's external surfaces. The baffle partitions the chamber into two sections. The
design of the tray and baffle are such that a predetermined restriction is introduced between
the two sides of the chamber. This restriction is used to generate the patented "push-pull"
mechanical scrubbing agitation action that facilitates instrument cleaning.
On the top, right side of the apparatus there is an interactive key pad that is positioned to be
easily viewed and accessed by a user. The interactive key pad includes a graphical liquid
crystal display that supplies general status information and prompts, illuminated status and
warning indicators, and control buttons.

5
The Instrument Processor System is a self-contained apparatus that automatically cleans
endoscopes. The system uses a combination of physical and chemical actions to achieve its
function.
To clean endoscopes placed in the apparatus, the system uses two stages. The first stage
uses a detergent for cleaning. The second stage rinses the endoscope twice and cleaning is
complete. The cleaning and rinse stages reduce the endoscope's soil burden.
After rinsing, remove the endoscope from the Instrument Processor System and subject the
endoscope to whatever process the facility uses to achieve high level disinfection.
The Instrument Processor relies on four fundamental process parameters to achieve its
cleaning function. The parameters include the TIME that the instrument being processed is
exposed to each process stage, the differential PRESSURE generated across the two sides of
the bisected processing chamber during the scrubbing agitation, the CONCENTRATION of
chemical, and the TEMPERATURE of the liquid that is exposed to the instrument being
processed. The software controls all of these parameters using an intricate system of
monitoring/sensing devices located throughout the device.

ENDOSCOPE TRAYS, AND BAFFLE INSERTS
Trays are used to position the endoscopes in the processing chamber and hold the
endoscopes in place during the cleaning and rinse cycles. There are two trays one on each
side of the baffle. To allow the endoscope to pass through the baffle, chamber baffle inserts
are removable and secure the endoscope as it passes through the baffle when inserted. The
baffle inserts are specific to the type of endoscope to be processed. There are four types of
inserts (see Appendix D – Trays and Inserts for more information on the combination of
trays and inserts to be used). This system allows the external surfaces and internal lumen
surfaces of the endoscope to be cleaned without attaching connectors to the ends of the
endoscope and facilitates removal of the cleaned endoscope.
INDICATIONS
The Langford IC Systems Instrument Processor, when used in accordance with its labeling
and the Zymit LF Detergent, provides cleaning to remaining protein levels of < 6.4 µg/cm²
on the inner lumen and outer surfaces of the endoscope in preparation for the high level
disinfection process.
The Zymit LF Detergent cleaning solution used in the Instrument Processor System is
compatible with the materials contained in the endoscopes to be processed. Reprocessed
endoscopes will contain minimal residual levels of detergent.
The volume of Zymit LF Detergent required for each cycle is conveniently measured by
filling the detergent reservoir to the prescribed fill level. The volume in the reservoir is
consumed during a normal processing cycle.
The Instrument Processor System will abort the processing and signal the user to take
corrective action if the monitored parameters are not within range.
Process parameters will be printed for Hospital Quality Assurance and / or Patient records
by the onboard printer contained inside the Instrument Processor System.
The Instrument Processor System facilitates compliance with the endoscope reprocessing
guidelines published by SGNA, APIC, AORN, ASGE, CDC, and other professional
organizations.

CONTRAINDICATIONS
Appendix A lists endoscopes that have been tested by Instrument Processor in the
Qualification of the Instrument Processor System’s cleaning cycles. Use only those
endoscopes that are published in this manual as compatible with the Instrument Processor
System. Additional endoscopes will be published in supplements to this manual for other
medical instruments validated in the future for processing in the Instrument Processor
System by Langford IC Systems.
Endoscopes that should not be processed with the System
Endoscopes that are not compatible with the Zymit LF Detergent based on compatibility
testing or literature information of material compatibility with the Instrument Processor
System process.
Do not process endoscopes that are not indicated for total submersion, see Appendix A.
Certain areas of the endoscope that require protective coverings prior to submersion must
have the protective coverings in place prior to placing the endoscope in the Instrument
Processor System chamber. Endoscopes that do not have appropriate protective coverings
for the aerating or irrigating channels, or cannot withstand a temperature of 140°F (60 °C)
should not be processed with the Instrument Processor System as damage to the endoscope
may result. Refer to the endoscope manufacturer’s manual for any cautions related to
protective coverings and/or temperature during reprocessing the endoscope.
WARNINGS
Do Not Use in Patient Areas. The Instrument Processor System is equipment that shall not
have contact with patients.
Use only those product(s), supplies, parts or accessories recommended by Langford IC
Systems in this manual (see Accessories and Supplies Section). Failure to do so may result
in ineffective cleaning or disinfection, damage to endoscope, and/or system malfunction.
The Instrument Processor System must be installed according to the instructions and
specifications provided in the Installation Procedures (see System Installation Section).
Failure to do so may result in ineffective cleaning, damage to endoscopes, system
malfunction and/or non-compliance with local codes.
It is the user’s responsibility to provide the Instrument Processor System with hot water at a
minimum temperature of 100°F but not to exceed 140°F. Although the Instrument
Processor System has an on-board hot water filter, Langford IC Systems recommends that
the user also supply filtered water.
Ensure that the endoscopes to be cleaned have been tested for leaks and lumen
obstructions according to the endoscope manufacturer’s instructions and current
professional practices prior to processing in the Instrument Processor System. This
involves wiping the outer surface of the endoscope with detergent, leak testing and passing a
small amount of detergent through the working lumen(s) to ensure that the lumen is not
occluded. Failure to perform these pre-processing steps may result in ineffective
cleaning and or damage to the endoscope.

If a process cycle is STOPPED (cancelled), either by the user or by the Instrument Processor
System’s operating system, the endoscope being processed is not safe to use.
Failure to properly secure the endoscope in the endoscope tray, properly select and place the
correct baffle insert and properly cover the non-submersible and pressure sensitive areas of
the endoscope may result in damage to the endoscope.
Review the instructions for use for the detergent prior to use. Contact Langford IC Systems
Customer Service at “1-508-337-6500” with any questions regarding the use of the
detergent.
Use only the 510(k) approved Zymit LF Detergent in the Instrument Processor System. The
active ingredients are ethanol, 1,2-dihydroxypropane and other proprietary chemical
substances. The concentrated solution is automatically diluted by the Instrument Processor
System to an in-use concentration of approximately 2%.
WARNING: Zymit LF Detergent is a skin irritant. Wear protective gloves and
eyeglasses. Avoid prolonged breathing of vapor. In case of contact, flush with
water. Do not mix with other detergents. Store at room temperature (5-30° C). A
Material Safety Data Sheet is provided with each shipment of Zymit LF Detergent
and is also available from Langford IC Systems Customer Service.
The Zymit LF Detergent requires no user preparation other than uncapping the
container and filling the detergent reservoir to the “Fill Line” on the reservoir.
The Zymit LF Detergent is the only agent 510(k) approved for use with the Instrument
Processor System. No other chemicals are authorized or recommended for use. The use of
other agents may result in ineffective cleaning or damage to the instrument being processed
or damage to the Instrument Processor System.
DANGER! Risk of EXPLOSION if the Instrument Processor System is operated in the
presence of flammable anesthetics!
A failure to follow the instructions in this manual along with the endoscope equipment
manufacturers cleaning procedures after each use can compromise patient safety.
Patient debris and reprocessing chemicals (detergent) are hazardous. Wear personal
protective equipment to safeguard against potentially infectious material and dangerous
chemical solutions. Follow universal precautionary standards and facility policies for
handling potentially infectious material and hazardous chemicals.

The Instrument Processor System continuously monitors the processing cycles to ensure
cleaning within the parameters validated for release of the processed instrument. If an error
occurs in the monitored parameters, the cycle will be ABORTED by the Instrument
Processor System controls.
The operator may also stop the operational cycle. Upon cycle cancellation, the cleaning
solution in the Instrument Processor System chamber drains and the chamber latch
deactivates.
If a cycle is either aborted or cancelled, endoscopes should be reprocessed or rinsed
manually immediately upon cancellation of the cycle in order to prevent detergent from
drying (concentrating) on the endoscope(s).
If an operational error occurs that results in the “Service Required” screen display, then
further processing by the machine will be suspended. Call the Customer Service at
Langford IC Systems at “1-508-337-6500”.
An incoming water temperature of greater than 140°F (60°C) will cause the system to
automatically shutdown to protect heat sensitive endoscopes from being damaged.
Do not process endoscopes that are not recommended to be processed by the Instrument
Processor System. See Appendix A.
Damage may occur to endoscopes if they are not properly secured in the appropriate
processing tray and the correct baffle insert selected.
Zymit LF Detergent has been developed for use with the Instrument Processor System only.
Do not use with other washer.
Do not expose the thermal printer paper to direct sunlight or overhead florescent lighting.
Premature color development will occur if the paper is exposed to high temperature, light or
scratched with a sharp object.
DANGER! Do not attempt to open the processing chamber during a cycle, as it is under
pressure. You must press and acknowledge the STOP button if access to the
endoscope is required prior to the completion of the cycle. Pressing and
acknowledging the STOP button will cause the machine to stop the cycle, drain
and release the interlock so that the chamber may be opened.

Thermal papers used
 Product No.: TP-211C-1 (10 rolls per box)
 Paper width: 58 mm
 Outer diameter of roll paper: φ50 mm or less
 Core: included
Use the specified thermal paper. If you use another type of thermal paper, the
quality of print and the useful service life of the thermal head may not be guaranteed.
2. Hot Water filter
The Instrument Processor System uses one water filter, a 2.0 micron filter. The 2.0
micron filter serves to remove large particles, sediment, from the incoming water hot
supply. The Instrument Processor System monitors time relevant to filter operation
and provides alarms when the filter needs replacement. However, it is
recommended that the user facility routinely monitor the microbial quality of the
rinse water used during endoscope reprocessing to assure the effectiveness of the
water filtration process. Filter life of the onboard filter can also be extended if you
connect the Instrument Processor System to one of the external filtration systems
normally located in the area where endoscopes are processed.
Suggested maintenance for the 2.0 micron hot water filter is as follows:
a. Every 7-10 days or when the Instrument Processor System indicates that the
filter needs replacement by listing an Exception #23
EX_C_CHAMBER_NOT_FULL, or #78 EX_C_BYPASS_TIMEOUT.
Check water pressure as these errors are also displayed when the chamber
does not fill because of low water pressure.
Note: Frequency of hot water filter replacement varies and depends on the
quality of the incoming water as well as whether or not pre machine user
facility filtration is being used. Slow fill times will generate an error
warning (see Exception #23 or #78 in the troubleshooting section)
requiring the hot water filter to be replaced.
CHANGING THE HOT WATER FILTER
The hot water filter should be changed when the fill rate warning prints out, lights up
or is indicated by the Screen Display of Exception #23 or #78. Use only LIC
authorized filters (see Accessories and Supplies section of this manual).
Make sure the Instrument Processor System is in the following condition prior to
changing the filter:
1. Ensure that there is no wash in progress (power is OFF or green Ready light
is ON on the control panel).
2. Turn the POWER to the Instrument Processor System OFF (if ON).
3. Turn the incoming hot water supply OFF.
Steps in changing the filter:

1. Shut off the hot water supply.
2. Obtain a strap wrench large enough (at least 4” O.D.) to accommodate the
diameter of the hot water filter housing.
3. Obtain a small tray to collect water that will fit under the hot water filter.
4. Open the front service door by using a tool (i.e. pen) to depress the door latch
button (see Figure 25).
5. Place the small tray under the hot water filter to collect the water runoff.
6. Using the strap wrench, turn the hot water filter housing to the left until loose
enough to turn by hand (see Figure 27).
7. Continue turning several turns by hand until the housing and filter separate
from the filter cover.
8. Empty the housing of water and discard the old filter.
9. Center and drop the new filter into the center of the empty filter housing (it
does not matter which end is up, as the filter has no polarity).
10. Reinstall the filter housing, turning to the right by hand (while keeping the
filter centered within the housing) until snug.
11. Using the strap wrench, tighten until fully seated (DO NOT OVER
TIGHTEN).
12. Remove the small tray, and discard the collected water runoff.
13. Turn the incoming hot water supply ON.
14. Keeping the door switch closed (see Figure 26), perform the following steps:
a) Turn the POWER to the Instrument Processor System ON
b) Follow the prompts to initialize the machine.
c) Check for water leaks under and around the hot water filter housing.
d) If the filter housing is leaking, tighten it using the strap wrench until the
leak stops. (DO NOT OVER TIGHTEN!)
e) Run a wash without an endoscope (use Inst ID #000000000, using the
“Other” instrument type).
f) While the chamber is filling during the first cycle, check for water leaks
under and around the hot water filter housing.
g) If the filter housing is leaking at any time during the fill, tighten it using
the strap wrench until the leak stops. (DO NOT OVER TIGHTEN!).
h) If the leak does not cease by the time the chamber has filled, turn off the
water and contact Langford IC customer service.
15. If leaks are not detected and the cycle entered the “Agitation” step release
the switch that detects the service door open, and close the service door.
16. Acknowledge the exception that occurs from having released the switch, and
allow wash recovery to complete.

Routine Maintenance of the Instrument Processor System Processing Chamber:
Periodic cleaning of the Instrument Processor System processing chamber is
recommended as a general maintenance procedure. The processing chamber is
constructed of stainless steel which is generally kept clean by the scrubbing action of
the Instrument Processor System cleaning cycle. Langford I C Systems recommends
that the chamber be reviewed at the end of each cleaning process to determine if any
staining or residue has occurred. Because of the continuous scrubbing action of the
process residue build up is not anticipated. If, however, it does occur or minor
staining occurs Langford IC Systems recommends using the cleaning methods
described in the “Designer Handbook, The Care and Cleaning of Stainless Steel”
published by the Specialty Steel Industry of North America. A copy of the handbook
is provided in Appendix C.

SPACE REQUIREMENTS
The Instrument Processor System must be installed on a level surface. However, the unit
has leveling pads so that minor adjustments may be made after installation, if necessary.
To prevent damage to the wheels, AFTER LEVELING THE WHEELS MUST BE OFF
THE FLOOR. See Figure 28 below.
Leveling Pad Adjustment

Figure 28: Caster Leveling Pad Adjustment
The dimensions of the Instrument Processor System, with the chamber lid closed and open,
are as follows:
Chamber Lid Closed: Dimensions (height/width/depth) 45-5/8 x 48 x 343/8 inches
(115.9 x 121.9 x 87.3 cm)
Chamber Lid Open: Dimensions (height/width/depth) 60.25 x 48 x 343/8 inches (153 x
121.9 x 87.3 cm)
Space requirements are the physical space that is taken by the device without regard to the
additional space needed for a person to walk around it. In addition to these measurements,
the Instrument Processor System has external components, such as the water hook-ups.
Accordingly, the following clearances are recommended: The water inlet line should have
8-10 in. clearance on the back side of the unit, so that the water hose can be connected and
are accessible.

DRAIN
CAUTION: The system drain operates via active pumps from the rear of the Instrument
Processor System.
Drain outlet – detail
Drain outlet
Figure 31: Drain Outlet Connection
The Instrument Processor System's drain connection is located on the back of the cabinet.
Consult your facilities department if you are installing multiple units. The user facility drain
system must have a capacity of at least 5 gal/min (18.9 L/min).
DRAIN PUMP SERVICE
The drain pump may need servicing after many hours of operation. There are two types of
servicing needs that may occur:
1. Circuit Breaker – Usually caused by the pump stalling, drawing too much current,
and tripping the internal circuit breaker. This results in drain time-out exception (i.e.
EX. #29), because the pump is disabled until the circuit breaker is reset.
2. Impeller Damage – Wear that causes individual vanes of the impeller to break off.
This causes the drain pump to run slower, resulting in longer cycle times from taking
longer to drain, and eventually resulting in drain time-out exception exception (i.e.
EX. #29).

DRAIN PUMP CIRCUIT BREAKER
When the Drain Pump Circuit Breaker breaks, there is usually a loud momentary vibrating
sound that the pump makes (which is much louder than the noise pump normally makes
when it’s operating and lasting a few seconds) before tripping the circuit breaker. Follow
these steps to reset the circuit breaker (Drain Time-out Exception):
CAUTION: Power to the Instrument Process System is “ON”.
1. Open the front service door.
2. Figure 32, Figure 33 and Figure 35 show where the Drain Pump Circuit Breaker is
located in the machine. Reach around inside and reset the pump circuit breaker as
shown in Figure 36.
3. Acknowledge the exception(s), and allow wash recovery to complete.
4. If the machine displays a service exception, enter the Service User ID to clear the
exception.
5. Endoscope in the chamber must be reprocessed.

REPLACING THE IMPELLER
The impeller needs to be checked periodically (see table), or when the chamber fails to
properly drain within the time-out by producing an exception, and the drain appears to be
free of blockages. The following shows a damaged impeller:
Broken vane,
replace impeller
Missing vane, most
likely sent to drain,
replace impeller
Cracked vane,
replace impeller
Figure 37: Damaged Drain Pump Impeller
If the Drain Pump Impeller needs inspecting or replacing, make sure the Instrument
Processor System is in the following condition prior to inspecting / changing the impeller:
1. Ensure that there is no wash in progress (power is OFF or green Ready light is ON
on the control panel).
2. Turn the POWER to the Instrument Processor System OFF (if ON).
To inspect or replace the Drain Pump Impeller, follow these steps:
1. Obtain a small tray to collect water that will fit under the Drain Pump Impeller
housing.
2. Open the front service door by using a tool/pen to depress the door latch button.
3. Place the small tray under the Drain Pump Impeller housing to collect the water
runoff.
4. Remove the four screws to remove the impeller housing cover (see Figure 26) and
examine the Drain Pump Impeller using the guideline shown in Figure 37.
5. If the impeller needs to be replaced, remove the damaged impeller and replace with a
new impeller.
6. Replace the impeller housing cover and four screws.
7. Remove the small tray, and discard the collected water runoff.
8. Keeping the door switch closed perform the following steps:
a) Turn the POWER to the Instrument Processor System ON
b) Follow the prompts to initialize the machine.
c) If the impeller cover is leaking, tighten it until the leak stops.
d) Run a wash without an endoscope (use Inst ID #000000000, using the “Other”
instrument type).

e) While the chamber is performing bypass and draining during the first cycle,
check for leaks by visually inspecting the impeller cover.
f) If the impeller cover is leaking at any time during the drain, tighten it until the
leak stops.
g) If the leak does not cease by the time the chamber has completed draining,
contact Langford IC Systems customer service.
9. Release the switch that detects the service door open, and close the service door.
10. Acknowledge the exception that occurs from having released the switch, and allow
wash recovery to complete.
11. Any endoscope left in the chamber must be reprocessed.
CHAMBER FULL, COVER CLOSED, CANNOT OPEN
This can happen for a variety of causes, but specifically from the chamber being left full
when the machine is shut off, as the auto latch won’t allow a full chamber to open upon
power up:
1. There is a Drain Pump Circuit Breaker failure or some other fault that results in a
Service Exception, for which the user is forced to turn off the machine without being
able to drain the chamber.
2. There is a power failure or the user shuts off power during a wash, leaving the
chamber full when the machine powers up.
If this happens, follow these steps after powering on the machine:
1. Power cycle the machine “OFF” and “ON”. The machine will enter the Initialization
step, follow the prompts to initialize the machine.
2. Press the “OPEN” switch to set the Auto-latch home position and open the chamber
lid.
3. Call Service if initialization does not reset the machine to operational mode
CAUTION: If a cycle is either aborted or cancelled, endoscopes should be
reprocessed or rinsed manually immediately upon cancellation of the cycle in order
to prevent detergent from drying (concentrating) on the endoscope(s). The endoscope
being processed is not safe to use.

Fill Pressure Exceeded
The chamber pressure was too high during POST. Call a
service technician.
The interlock is still engaged after a wash indicating the lid
is considered not safe to open. A faulty level sensor, a faulty
ball valve, a motor fault are all possible reasons for this
warning being issued. If this condition remains, the lid will
not be allowed to open, requiring service.
The lid was opened during a wash cycle.
The chamber absolute pressure was over the SRS specified
limit during agitation. This exception is posted when the
absolute chamber pressure is too high during agitation. This
could be caused by improper placement of the endoscope in
the tray, a clogged endoscope, or a bad tray. Reposition the
endoscope in a new tray, and try the wash again.
After draining the chamber, LS5 indicated the chamber was
still full.
During a fill, the chamber pressure rose above the minimum
level. This could be caused by a failed solenoid valve, ball
valve, or level sensor. Clean the chamber level sensors. Try
the wash again, and if that doesn’t work, call a service
technician.

WHAT IS STAINLESS STEEL
Cleanliness and stainless steel are
Stainless steel is not a single alloy, but rather the name applies to a group of iron-based

Table 2 STANDARD MECHANICAL SHEET FINISHES
Unpolished or Rolled Finishes:
No. 1 A rough, dull surface which results from hot rolling to the specified thickness followed by annealing
and descaling.
No. 2D A dull finish which results from cold rolling followed by annealing and descaling, and may perhaps get
a light roll pass through unpolished rolls. A 2D finish is used where appearance is not of primary concern.
No. 2B A bright, cold-rolled finish resulting in the same manner as No. 2D finish, except that the annealed and
descaled sheet receives a final light roll pass through polished rolls. This is the general-purpose cold-rolled
finish that can be used as is or as a preliminary step to polishing.
Polished Finishes:
No. 3 An intermediate polish surface obtained by finishing with a 100-grit abrasive. Generally used where a
semifinished polished surface is required. A No. 3 usually receives additional polishing during fabrication.
No. 4
A polished surface obtained by finishing with a 120-150 mesh abrasive, following initial grinding with coarser
abrasives. This is a general-purpose bright finish with a visible “grain” which prevents mirror reflection.
No. 6
A dull satin finish having lower reflectivity than No. 4 finish in a medium of abrasive and oil. It is used for
architectural applications and ornamentation where a higher luster is undesirable, and to contrast with
brighter finishes.
No. 7
A highly reflective finish that is obtained by buffing finely ground surfaces but not to the extent of completely
removing the “grit” lines. It is used chiefly for architectural and ornamental purposes.
No. 8
The most reflective surface obtained by polishing with successively finer abrasives and buffing extensively
until all grit lines from preliminary grinding operations are removed. It is used for applications such as mirrors
and reflectors.

CLEANING OF
STAINLESS STEEL
Stainless steels need to be cleaned for
aesthetic considerations and to preserve
corrosion resistance. Stainless steel is
protected from corroson by a thin layer of
chromium oxide. Oxygen from the
atmosphere combines with the chromium
in the stainless steel to form this passive
chromium oxide film that protects from
further corrosion. Any contamination of the
surface by dirt, or other material, hinders

* Surface finishes (b), (e) and (f) are applicable to round bars only.
** Bars of the 4xx series stainless steels which are highly hardenable, such as Types 414, 420, 420F, 431, 440A,
440B and 440C, are annealed before rough turning. Other hardenable grades, such as Types 403, 410, 416 and
416Se, may also require annealing depending on their composition and size.
