a. PYREX®is a registered trademark of Corning Incorporated.
The liquid cycle is for non-patient contact use only.
WARNING – BURN HAZARD:
When sterilizing liquids, to prevent personal injury or property damage resulting from bursting bottles
and hot fluid, you must observe the following procedures:
• Use Liquid cycle only; no other cycle is safe for processing liquids.
• Use only vented closures; do not use screw caps or rubber stoppers with crimped seal.
• Use only Type I borosilicate glass bottles; do not use ordinary glass bottles or any container not
designed for sterilization.
• Do not allow hot bottles to be jolted; this can cause hot-bottle explosions. Do not move bottles if any
boiling or bubbling is present.
Sterilizer, rack/shelves, and loading car will be hot after cycle is run. Always wear protective gloves
and apron when removing a processed load. Protective gloves and apron must be worn when reloading
sterilizer following the previous operation.
Do not attempt to open the sterilizer door if a WATER IN CHAMBER ALARM condition exists. Call a
qualified service technician before attempting to use sterilizer further.
After manual exhaust, steam may remain inside the chamber. Always wear protective gloves, apron,
and a face shield when following emergency procedure to unload sterilizer. Stay as far back from the
chamber opening as possible when opening the door.

SAFETY PRECAUTIONS 1

1-2
P129394-176 Operator Manual Safety Precautions
WARNING – EXPLOSION HAZARD:
WARNING – SLIPPING HAZARD:
WARNING – PERSONAL INJURY HAZARD AND/OR EQUIPMENT DAMAGE HAZARD:
Allow sterilizer to cool to room temperature before performing any cleaning or maintenance
procedures.
Failure to shut off the steam supply when cleaning or replacing strainers can result in serious injury.
Jacket pressure must be 0 psig before beginning work on the steam trap.
Proper testing of the safety valve requires the valve to be operated under pressure. Exhaust from
the safety valve is hot and can cause burns. Proper safety attire (gloves, eye protection, insulated overall)
as designated by OSHA, is required. Testing is to be performed by qualified service personnel only.
Steam may be released from the chamber when door is opened. Step back from the sterilizer each
time the door is opened to minimize contact with steam vapor.
This sterilizer is not designed to process flammable compounds.
To prevent falls, keep floors dry by immediately wiping up any spilled liquids or condensation in
sterilizer loading or unloading area.
Regularly scheduled preventive maintenance is required for safe and reliable operation of this equipment.
Contact your STERIS service representative to schedule preventive maintenance.
When closing the chamber door, keep hands and arms out of the door opening and make sure opening is
clear of obstructions.
Repairs and adjustments to this equipment must be made only by fully qualified service personnel.
Maintenance performed by inexperienced, unqualified persons or installation of unauthorized parts could
cause personal injury, result in costly equipment damage and/or void the warranty.
The performance of the 510k cleared AMSCO C Series Sterilizer is validated as a system including
components defined by STERIS in the Operator Manual and Service Manual for the AMSCO C Series
Sterilizer. Substitution of unauthorized components can potentially lead to personal injury, damage or
premature failure of the product and result in a unit configuration that is inconsistent with the validated,
FDA cleared product. Altering the equipment or using unapproved component’s may void STERIS’
warranty. DO NOT USE components that are not validated as part of the AMSCO C Series Sterilizer.
WARNING – STERILITY ASSURANCE HAZARD:
Load sterility may be compromised if the biological indicator or air leak test indicates a potential problem.
If these indicators show a potential problem, refer the situation to a qualified service technician before
using the sterilizer further.
WARNING – BURN HAZARD: (CONTINUED)

Safety Precautions Operator Manual P129394-176
CAUTION – POSSIBLE EQUIPMENT DAMAGE:
According to AAMI standards, a measured leak rate greater than 1 mm Hg/minute (1.3 mbar/min)
indicates a problem with the sterilizer. Refer the situation to a qualified service technician before using the
sterilizer further.
Gasket must be fully retracted prior to operating sterilizer door.
If 0 dry time is selected, sterilizer automatically initiates a vapor removal phase in place of drying. This
phase can still draw a vacuum to 5 inHg. Consult device manufacturer’s recommendations to ensure
devices being processed can withstand this depth of vacuum.
Lifting the chamber float switch when cleaning the chamber may cause the sterilizer control to initiate a
“Chamber Flooded” alarm. If this alarm condition occurs, the operator must turn the control power OFF
then ON to clear the alarm. The control power switch is located in the mechanical area at the side of the
sterilizer. Placing the sterilizer in standby does not clear this alarm.
Never use a wire brush, abrasives or steel wool on door and chamber assembly. Do not use cleaners
containing chloride on stainless-steel surfaces. Chloride-based cleaners will deteriorate stainless steel,
eventually leading to failure of the vessel.
Do not use cleaners containing chlorides on loading cars. Chloride-based cleaners will deteriorate the
loading car metal.
Sterilization of chloride-containing solutions (e.g., saline) can cause chamber corrosion and is not
recommended by the manufacturer. If, however, chloride-containing solutions must be processed, clean
the chamber after each use.
Allow thermostatic traps to cool down to room temperature before removing cover. Since there is nothing
to limit expansion, the bellows may rupture or fatigue if trap is opened while hot.
Actuation at less than 75% of rated pressure can allow debris to contaminate the seat and cause the
safety valve to leak. A leaking safety valve must be replaced.
Insufficient service clearance will make repairs more difficult and time-consuming.
Piping sized too small may cause water hammer, resulting in damage to the sterilizer.
After installation, it is mandatory to brace piping at the drain funnel so that it will not move vertically.
Make sure door opening is clear of any obstruction before closing the door(s).
Do not attempt to open sterilizer door during manual operation unless chamber is at 0 psig.
During manual operation, gasket must be fully retracted prior to operating sterilizer door.
Immediately wipe up saline solution spills on loading car to prevent damage to stainless steel.
