as well as expert repair services. Contact your STERIS
representative for details.
Indications for Use The AMSCO®400 Series™ Small Steam Sterilizer is designed for
sterilization of heat- and moisture-stable materials used in healthcare
facilities and is available in two configurations:
•Prevacuum – designed for sterilization of heat- and moisture-
stable materials. The Prevacuum sterilizer is equipped with
Prevacuum, Gravity, Liquid, Leak Test and Daily Air Removal
(Bowie-Dick) test cycles.
•Steam Flush Pressure Pulse (SFPP) – designed for sterilization
of heat and moisture-stable materials. The SFPP sterilizer is
equipped with SFPP, Prevacuum, Gravity, Liquid, Leak Test and
Daily Air Removal (Bowie-Dick) test cycles.
Important: The liquid cycle is for non-patient contact use only.

Safety Precautions Operator Manual P129394-020
1
The following Safety Precautions must be observed when operating or servicing this AMSCO®400 Series Small
Steam Sterilizer. WARNING indicates the potential for personal injury and CAUTION indicates the potential for
damage to equipment. For emphasis, certain Safety Precautions are repeated throughout the manual. It is
important to review all Safety Precautions before operating or servicing the unit.
Strictly following these Safety Precautions enhances the Customer’s ability to safely and effectively utilize the unit
and helps avoid improper maintenance methods which may damage the unit or render it unsafe. It is important to
understand that these Safety Precautions are not exhaustive; Customers are encouraged to develop their own
safety policies and procedures to enhance and complement these Safety Precautions.
Important: Please read this Equipment Manual to get the best understanding and to help ensure best
performance of this equipment, which has been throughly inspected, tested and adjusted by factory-trained
personnel.
• Equipment maintenance other than described in the manual (unless by authorized representatives of the
STERIS Corporation), shall be at the risk of invalidating the equipment warranty.
• To obtain authorized service call:
STERIS Corporation
Healthcare: 1-800-548-4873
Life Sciences: 1-800-444-9009
WARNING – ELECTRIC SHOCK AND BURN HAZARD:
WARNING – PERSONAL INJURY HAZARD:
WARNING:
Sterilizers may be equipped with up to three electrical connection points (sterilizer control,
vacuum pump and/or integral steam generator). Each electrical supply must be provided with a
separate disconnect. Disconnect all utilities to sterilizer before servicing. Do not service the
sterilizer unless all utilities have been properly locked out. Always follow OSHA Lockout-Tagout and
electrical safety-related work practice standards.
Avoid personal injury from bursting bottles. Liquid sterilization cycle must only be used for liquids in
borosilicate (Pyrex®a) flasks with vented closures.
a. PYREX®is a registered trademark of Corning Incorporated.
The liquid cycle is for non-patient contact use only.

SAFETY PRECAUTIONS 1

1-2
P129394-020 Operator Manual Safety Precautions
WARNING – EXPLOSION HAZARD:
WARNING – SLIPPING HAZARD:
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.
• Processed bottles are hot following liquid cycle and may boil over. Always wear appropriate PPE
including thermal gloves and goggles when removing processed bottles from chamber. Do not move
bottles if any boiling or bubbling is present. Do not allow hot bottles to be jolted; this can cause hot-
bottle explosions.
Reduce risk of liquid boil-over. Do not place liquid-filled bottles within 4” (102 mm) of chamber door
during processing.
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.
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.
