Safety Precautions Operator Manual 122997-341
1
The following Safety Precautions must be observed when operating or servicing this equipment. WARNING indi-
cates the potential for personal injury and CAUTION indicates the potential for damage to equipment. For empha-
sis, certain Safety Precautions are repeated throughout the manual. It is important to review ALL Safety
Precautions before operating or servicing the unit.
WARNING – PERSONAL INJURY AND/OR EQUIPMENT DAMAGE HAZARD:
WARNING – PERSONAL INJURY HAZARD:
WARNING – ELECTRIC SHOCK AND/OR BURN HAZARD:
Always wear appropriate Personal Protective Equipment (PPE) when cleaning or removing debris from
bottom of wash chamber and over suction plate.
Only STERIS or STERIS-trained service personnel should make repairs and adjustments to this equip-
ment. Maintenance done by inexperienced, unqualified personnel or installation of unauthorized parts
could cause personal injury, invalidate warranty, or result in costly damage. Contact STERIS regarding
Service options.
Regularly scheduled preventive maintenance, in addition to faithful performance of minor maintenance
described within this manual, is required for safe and reliable operation of this equipment. Contact
STERIS to schedule preventive maintenance.
To open doors from inside wash chamber, pull EMERGENCY STOP cables. Washer operation will
automatically stop. Then, push firmly on door panel using shoulder and upper arm, applying upper body
force.
Items in washing cart may move during processing and be filled with residual hot water or protrude from
cart at the end of the cycle. Always wear appropriate personal protective equipment (PPE) and carefully
remove items from cart.
Never perform cleaning of wash chamber until full cycle has been completed. If cycle has not been
completed, contaminated debris or water may remain in the bottom of the wash chamber.
Keep fingers away from door hinges to prevent pinching.
To prevent tipping, place biggest and heaviest items on the lower levels of accessory cart.
Disconnect all utilities to washer before servicing. Do not service washer unless all utilities have been
properly locked out. Always follow local occupational health and safety regulations, as well as electric
and plumbing codes.
SAFETY PRECAUTIONS

1-2
122997-341 Operator Manual Safety Precautions
WARNING – CHEMICAL BURN AND/OR EYE INJURY HAZARD:
WARNING – BURN HAZARD:
WARNING – SLIPPING HAZARD:
CAUTION – POSSIBLE EQUIPMENT DAMAGE:
Washer chemicals are caustic and can cause adverse effects to exposed tissues. Do not get in eyes, on
skin, or attempt to swallow. Read and follow precautions and instructions on chemical label and in
Material Safety Data Sheet (MSDS) prior to handling detergent containers, or servicing detergent injec-
tion pumps, tank, and lines. Wear appropriate Personal Protective Equipment (PPE) whenever handling
chemicals or servicing chemical injection pumps, tank, and lines.
Wear appropriate Personal Protective Equipment (PPE) when removing clamps and replacing squeeze
tubes. Residual chemicals might remain in used squeeze tubes. If chemical contacts skin or eyes,
immediately flush with running water for at least 10 minutes. If contact was with eyes, seek medical
attention.
Wear gloves and eye protection when using a descaling product. Avoid contact with eyes or skin. If
spilled or splashed, flush with plenty of water for 15 minutes. If swallowed, DO NOT induce vomiting.
Administer an alkali with plenty of water. Seek medical attention immediately.
Allow unit to cool down before performing any service on mechanical components and on piping. Com-
ponents and piping become very hot during operation.
Inner surfaces of washer are very hot after cycle completion. Operator should wear appropriate Per-
sonal Protective Equipment (PPE) and avoid all contact with inner walls when entering chamber to
unload washer.
Pipes may be extremely hot.
When cycle is complete, partially open chamber door and allow chamber and load to cool. Hot steam
may escape through door opening if door is fully opened after a cycle.
To avoid slippery floor conditions, keep floor dry. Promptly wipe up any spilled liquids or condensation. If
spilled liquids are detergents or other chemicals, follow safety precautions and handling procedures set
forth on detergent or chemical label and/or Material Safety Data Sheet (MSDS).
Always use non-foaming chemical for effective cleaning and proper pump and water level control opera-
tion. Follow manufacturer’s recommendations for amount of chemical to be used.
Always use a silicone lubricant to lubricate squeeze tubes. Petroleum-based lubricants, such as
Vaseline®1 or grease, will cause squeeze tubes to melt.
Avoid product damage. Always select a cycle appropriate for items being processed.

Safety Precautions Operator Manual 122997-341
CAUTION – POSSIBLE EQUIPMENT DAMAGE (Cont’d):
Before operating unit, always position manifolded Bottle Washing Cart over central water inlet connec-
tor. If manifolded accessory is not positioned correctly, damage may result and unit will be unable to
effectively wash load.
Do not process load using Bottle Washing Cart when Automatic Floor Tilting option is activated. If Auto-
matic Floor Tilting is used, manifolded water inlet and washer will be damaged.
Remove all cellulose-type bedding from cages and pans before processing. Cellulose bedding can clog
filters and piping.
Use nonabrasive cleaners when cleaning unit. Follow directions on containers and rub in a back-and-
forth motion (in same direction as surface grain). Abrasive cleaners will damage stainless steel. Clean-
ers rubbed in a circular motion applied with a wire brush or steel wool will scratch and dull stainless
steel. Do not use these cleaners on painted surfaces.
When choosing a detergent, select one with a low chloride content. Detergents with a high chloride con-
tent can corrode stainless steel.

2.3 Chemical Additives
Specifications
The selection of chemical additives is open for customer preference;
however, in order to achieve optimal performance, the selected
chemical additives must meet as a minimum, the following specifica-
tions:
NOTE: When choosing and using chemicals, take note of the follow-
ing:
1) Follow chemical label recommendations for concentration of
chemical to use.
2) Follow chemical manufacturer's recommendations to determine
the temperature of the WASH treatment.
3) Follow chemical manufacturer's recommendations for the amount
of chemical used according to water hardness.
To achieve maximum cleaning efficiency, select chemical appropri-
ate to soil type being processed. STERIS recommends the following
chemicals:
